  In many situations land managers have recollections or anecdotes about an area such as, “This pasture used to produce more grass” but do not have data to backup these statements. Repeat photography is a simple and relatively quick way to monitor rangelands. Repeat photography can illustrate changes over space and time for rangeland attributes like plant growth, species composition, total plant cover, litter, spatial arrangement of plants, and soil erosion. These are all important attributes that can be related to grazing management practices, fire, drought, precipitation, and other environmental variables. When it comes to convincing others that management practices are improving the landscape, a series of photographs taken at the same location through the years can vividly demonstrate change on the range. It is especially important to document change when people may have the historical context of the landscape.

  Allen et al. (2011) defined rangelands as: Arid and semi-arid land on which the indigenous vegetation is predominantly grasses, grass-like plants, forbs, or shrubs that are grazed or have the potential to be grazed, and which is used as a natural ecosystem for the production of livestock and wildlife. Rangelands may include natural grasslands, savannas, shrub lands, many deserts, steppes, tundras, alpine communities, and marshes.

  More info

  Abstract This paper reviews the literature and reports on the current state of knowledge regarding the potential for managers to use visual (VC), auditory (AC) and olfactory (OC) cues to manage foraging behaviour and spatial distribution of rangeland livestock. We present evidence that free-ranging livestock use these sensory cues to make decisions about foraging, drinking, habitat selection and spatial distribution, and to detect and avoid predators. This knowledge provides managers with opportunities to favourably alter behavioural patterns of rangeland ungulates. Opportunities to use sensory cues to shape livestock spatial distribution patterns arise primarily from the abilities of animals to: (a) learn to respond to cue-consequence associations that enhance their ability to adapt to changing foraging environments on rangelands, (b) generalize learned cue-consequence associations across spatial and temporal foraging scales and (c) influence one another's behaviour through social learning. Key literature on cue-consequence principles is initially reviewed from fine-scale studies (e.g., controlled studies conducted in mazes, arenas). Applications of cue-consequence principles are then highlighted from literature dealing with field-scale studies (e.g., controlled and observational studies conducted in large pastures or paddocks). We then discuss potential management implications derived from these studies. Finally, we summarize conclusions and recommendations for potential future research directions. The studies reviewed here suggest that VC, AC and OC associated with positive or negative reinforcers can be used to effectively direct livestock towards or away from selected areas. The feasibility of favourably altering grazing pressure on rangelands without having to build expensive, static fences has the potential to provide substantial economic and ecologic advantages.

  Abstract During March 2001–December 2003, we measured use of forage and height of stubble in pastures at low, middle, and high elevations. In years with higher precipitation, use of forage by cattle (Bos taurus) and elk (Cervus elaphus) was less in the middle elevation compared to low and high elevations. In the worst drought year on record (2002), use of forage increased with elevation. Overall, use of forage was greater in 2002 than in 2001 and 2003. Shorter stubble corresponded to lower production and higher use of forage. Total use of forage did not exceed 50%.

  Abstract: The challenges associated with wolf restoration programs vary regionally and depend on a myriad of interacting factors. Actual predation events, as well as social and environmental factors, can influence vigilance rates of prey species that forage in the presence of predators. Moreover, prey response to a particular predator species may vary depending on the environmental and evolutionary history of predator?prey relationships, as well as on the unique hunting strategy of the predator species. A more complicated situation exists on rangelands occupied by livestock, wild ungulates, and wolves. Some recent work has been done in the northern Rocky Mountains, but most of our limited understanding of wolf?livestock interactions is based primarily on older studies from Canada, Europe, and the upper Midwest. The extent and magnitude of wolf reintroduction effects on regional livestock production, however, remain largely unknown. In fact, considerable controversy exists regarding the effect of wolves on livestock-rearing systems.

  Abstract: Radiotelemetry is an important tool for wildlife management and research, but in some cases attachment of neck collars can be problematic. An alternative in large mammals is to attach transmitters to the ear, though little is published about ear-tag radiotransmitter integrity (i.e., how long a transmitter emits a useful signal) and retention (i.e., how long a transmitter remains attached to an animal). Here we report eartag transmitter integrity and retention from 2 studies monitoring free-ranging calves (Bos taurus) in eastern Arizona, USA, and feral horse (Equus ferus) foals in northwestern Spain. Transmitter integrity and retention was lower for transmitters attached to foals then calves. The primary cause for reduced integrity was antennas breaking off, whereas the primary retention problem involved transmitters ripping out of the ear. When data were pooled across study sites, mean integrity and retention loss was 111 days and 180 days, respectively. Transmitters attached to the interior of the outer ears had retention rates >2 times higher than transmitters attached to the exterior of the outer ear (88% vs. 43%). We recommend that researchers intending to utilize ear-tag transmitters for studies on large domestic or wild animals attach transmitters to the interior of the outer ear, reinforce transmitter antennas in order to improve integrity, and report integrity and retention rates. © 2012 The Wildlife Society.

  Abstract: New Mexico State University and the University of Arizona sent a comprehensive evaluation survey called Southwestern Noxious/Invasive Weed Short Course in April 2009 in order to increase awareness of invasive weed impacts. Each topic offered at the Short Course is presented within the framework and utility of applying integrated weed management (IWM) approaches to deal with invasive plants. An evaluation survey was administered following a derivation of the widely recognized total design methodology. The respondents represented a wide variety of land managers from 19 different organizations or entities who were attempting to manage invasive weeds on both private and public land. The results of study showed that the overwhelming majority of respondents increased their awareness and knowledge of the negative impacts of invasive weeds as a result of attending the Short Course. The survey results indicate that the Short Course's theme of couching management techniques within the context of IWM was very important.

  Abstract: The article discusses the effects of a rotational cattle grazing system on Elk Diets in Arizona Piñon-Juniper Rangeland. Overall proportions of the various plant species in cattle and elk diets were as expected and agree with the general classification of cattle and elk as grazers and intermediate feeders, respectively. Diet quality generally agreed with the results from diet composition. Again it was not surprising that elk diets containing more forbs and shrubs were higher in protein than cattle diets. One factor that might have exaggerated the researchers' observed differences in cattle versus elk diet quality was that they sampled cattle feces once at the end of the grazing period in their respective pastures. The grazing system as applied in this study did not accomplish the management goal to attract elk to pastures recently grazed by cattle and reduce grazing pressure on the rested pastures.

  Abstract: Conserving large carnivores throughout the world will often require that they share the landscape with livestock. Minimizing depredations and increasing tolerance by livestock producers will be critical for conservation efforts. To investigate factors influencing calf mortality and producer detection rates (i.e., number of livestock killed by predators, found by producers, and correctly classified as to cause of death), we monitored radio-tagged domestic calves at two sites in the Mexican wolf recovery area (East Eagle [EE] and Adobe Ranch [AR]). Study areas differed in grazing practices, density of predators (mountain lions, black bears, coyotes, and Mexican wolves), and amount of effort spent monitoring cattle. We radiotagged 618 calves over 3.5. years, and 312 calves over 2 years on the EE and AR, respectively. The overall proportion of radioed calves that died was higher on the EE (6.5%) than on the AR (1.9%). Predators (especially mountain lions) accounted for 85% of mortality on the EE and 0% on the AR. Calves selected by predators were on average 25 days younger than the surviving cohort. Our results indicate that year-round calving, especially in areas with high predator densities, are subject to higher losses primarily because calves are exposed to mortality agents for longer periods of time rather than having higher natural rates of mortality. We found a significant difference in producer detection rates between study sites, likely due to differences in the intensity of monitoring cattle between sites. On the EE, the producer detected 77.5% of mortalities and on the AR, the producer detected 33% of mortalities. Our results support changing husbandry practices to limit calving to a seasonal endeavor and that performance payment may be a better compensation strategy than ex post compensation schemes. © 2010.

  PMID: 19429201;Abstract: Wild and domestic ungulates modify their behaviour in the presence of olfactory and visual cues of predators but investigations have not exposed a domestic species to a series of cues representing various predators and other ungulate herbivores. We used wolf (Canis lupus), mountain lion (Puma concolor), and mule deer (Odocoileus hemionus) stimuli (olfactory and visual), and a control (no stimuli) to experimentally test for differences in behaviour of cattle (Bos taurus) raised in Arizona. We measured (1) vigilance, (2) foraging rates, (3) giving up density (GUD) of high quality foods and (4) time spent in high quality forage locations in response to location of stimuli treatments. In general, we found a consistent pattern in that wolf and deer treatments caused disparate results in all 4 response variables. Wolf stimuli significantly increased cattle vigilance and decreased cattle foraging rates; conversely, deer stimuli significantly increased cattle foraging rate and increased cattle use of high quality forage areas containing stimuli. Mountain lion stimuli did not significantly impact any of the 4 response variables. Our findings suggest that domestic herbivores react to predatory stimuli, can differentiate between stimuli representing two predatory species, and suggest that cattle may reduce antipredatory behaviour when near heterospecifics. © 2009 Elsevier B.V.

  Abstract: Vigilant behavior in wild ungulates is critical to guard against predation. However, few studies have examined vigilant behavior in domesticated ungulates. Considering the expansion of large predator populations, understanding vigilant behavior and factors that influence it will help with the management of livestock. We observed adult female cattle (Bos taurus L.) in open-range conditions where large predators (wolves [Canis lupus L.] and mountain lions [Puma concolor (L.).]) were common threats during summers of 2005 and 2006 in eastern Arizona. This study was designed to determine 1) to what extent cattle exhibit vigilant behavior compared to published data on wild ungulates, 2) whether predation events influence vigilance rates of cattle, and 3) whether social and environmental factors affect vigilance of cattle. Cattle exhibited vigilant behavior (3% ± 0.19%) during peak foraging periods, but at a lower rate than wild ungulates. Cows with calves were more than twice as vigilant (4.5% ± 0.46%) as those without calves (2.0% ± 0.27%). Single cattle and groups of two to five exhibited higher vigilance rates (4.2% ± 0.79%) than groups of six to 20 (2.5% ± 0.32%) and groups of > 20 (3.0% ± 0.41%). Cattle in groups of > 20 increased vigilance as visual obstruction increased. Mother cows whose calves were preyed upon (n = 5) exhibited a 3% to 48% increase in vigilance within 3 d after their calves were killed; this rate returned to near baseline levels after 10 d. Conversely, mother cows reduced foraging after their calves were killed from 88.5% ± 1.69% to 43.5% ± 11.4%; foraging rate also returned to near baseline levels after 10 d. Cattle exhibit vigilance at lower levels compared to wild ungulates, but this behavior appears to be at least partially an antipredatory behavior. Our findings provide support that predators can influence cattle behavior.

  Social learning can be of critical importance to cattle grazing rangeland environments with high variability of food resources across space and time. Experienced individuals can greatly facilitate foraging decisions (what to eat and where to eat) of naïve peers in such settings. We conducted an experiment with cattle to investigate strength and persistence of socially induced food and feeding site avoidance behaviours. Sixteen naïve yearling steers were paired with 16 social models that had either not been trained (control) or been trained with an emetic (LiCl), electrical shock or both to avoid: (a) an unsafe high-quality food (LiCl); (b) an unsafe high-quality feeding site (shock); or (c) both the unsafe high-quality food and the unsafe high-quality feeding site (LiCl + shock). Ten-minute trials were conducted in an experimental arena containing three artificial feeding sites each consisting of groups of bowls with either high- (HQ) or moderate-quality (MQ) foods (HQ = barley and oat grain; MQ = Bermuda grass hay). Unsafe high-quality (UHQ, surrounded by traffic cones) and safe moderate-quality (SMQ) feeding sites consisted of nine rubber bowls containing either HQ or MQ foods. The safe high-quality (SHQ) feeding site consisted of two groups of eight bowls containing HQ food, which surrounded the UHQ and SMQ feeding sites. Social models did not induce diet and feeding site avoidance behaviours in naïve steers; they exerted small and transient changes in the feeding behaviour of their naïve counterparts. Consequences to the individual outweighed social influences; when naïve animals experienced the same punishment contingencies as their social models, their behavioural patterns closely resembled those of their social model. Conditioned food and location aversions via LiCl were apparently influenced by prior exposure to target foods and the experimental arena. Conversely, conditioned feeding site avoidance via shock was apparently not influenced by prior exposure to target foods or the experimental arena.

  Abstract Free-grazing ruminants forage in environments containing multiple levels of complexity; the forage selection process operates at the landscape scale, when selecting feeding sites, and at the plant part level when selecting actual bites. Pen trials have shown that livestock associate visual cues with feeding sites, however, no field study has shown that animals generalise from training with visual cues in pens in order to choose feeding sites in the field. Our study tested nine beef heifers’ ability to generalise a learned visual cue association to select feeding sites in a rangeland setting offering a novel forage, Lehmann lovegrass (LL). Initially, animals were trained to associate high quality feed with a visual cue during pen trials. We then tested animal response to the cue before and after they gained 14-day grazing experience with LL. Two identical field experiments (i.e., novel, before animals had experienced foraging LL versus familiar, after the animals had 14-day grazing experience with LL) were conducted over 3-day periods. Each experiment consisted of 27, 10-min trials. Animals were tested in plots containing high quality (HQ) and low quality (LQ) LL patches. For each trial, one of three randomly selected scenarios was presented: (1) the visual cue was placed in the HQ patch, (2) the visual cue was placed in the LQ patch, or (3) no visual cue was placed in either patch. Dependent variables were first patch-type chosen, bite rate in each patch, and number of observations of grazing in each patch. Cue presence influenced initial patch choice, bite rate, and grazing tallies within patch type. Heifers took 212 more HQ bites than LQ bites when the cue was placed in the HQ patch ( P P P

  Abstract: In the southwestern United States, local weed management programs are increasingly important in weed prevention and control; however, little is known about the effectiveness of different local approaches to weed management. We surveyed coordinators of 53 local weed management programs in Arizona, Colorado, New Mexico, and Utah to determine how 4 key program attributes (interagency coordination, volunteer participation, regulatory authority and enforcement, and the state in which the program was located) were related with 4 performance measures: weed control, public education and outreach, weed monitoring, and integrated weed management. Based on the responses of 42 program coordinators (79%) we found that 1) weed programs that coordinated their activities with other organizations and those with citizen volunteers conducted more monitoring, but programs that did not coordinate or use volunteers treated more of their infested acreage; 2) programs that used a light-handed regulatory approach conducted more weed control than those with more punitive enforcement regimes or no enforcement authority; and 3) Colorado programs conducted more outreach and education than did programs in the other 3 states. Thus, although volunteer involvement and interagency coordination contributed to the performance of the local weed programs studied, particularly in monitoring, they have not compensated for the lack of locally enforceable weed regulations or adequate funding. Successful weed management in southwestern United States will require adequately funded, locally adapted approaches supported by locally enforceable weed regulations.

  Abstract: Many grazing-management challenges stem from poor livestock distribution resulting in overuse of some areas and low utilization of others. Managing livestock-distribution patterns requires knowledge of pasture characteristics and animal behavior patterns. Behavioral patterns result from recognizable processes that include inherited attributes, individual and social learning systems, cue-consequence specificity, predispositions toward novel stimuli, and spatial memory. Through these behavioral mechanisms, animals form and revise preferences and aversions for specific locations in their foraging landscape. To accomplish habitat selection, domestic herbivores use sight and sound cues to seek and return to high-quality foraging locations. Nested within habitat selection are learned diet preferences and aversions by which ungulate herbivores associate taste with positive or negative postingestive feedback. The deliberate and careful modification of animal attributes and habitat characteristics could yield options for adaptive rangeland management. In this article, we describe the basic principles that underlie how animals make decisions about where to forage and how long to stay in a particular habitat. We also suggest management practices designed to modify animal behavior and alter habitat-use patterns.

Moreover, overuse of and lowered carrying capacity in suboptimal habitats could contribute to resource degradation (e.g., overgrazing in marginal habitats, increased erosion and sedimentation) and lower producer profits due to declines in livestock production (e.g., weight gain, body condition, lamb or calf crop). Thus, indirect impacts of predation may have negative impacts on the ecological integrity of the land, as well as negative impacts on personal,

  Animals possess an external or skin-defense system that protects them from aggressions inflicted by predators, and an internal or gut-defense system that deters them from over-ingesting toxins. We conducted a study with cattle to investigate the relation between skin- and gut-defense systems and their influence on diet and habitat selection. Sixteen yearling steers were randomly assigned to one of four treatment groups and were exposed individually to an experimental arena during multiple 10 min trials during which they were allowed to select between an unsafe high quality habitat (UHQ) surrounded by traffic cones (visual cues), a safe, uncued high quality habitat (SHQ), or a safe, uncued moderate quality habitat (SMQ). Experimental habitats were made up of groups of bowls containing barley and oat grain (UHQ and SHQ habitats) or Bermuda grass hay (SMQ habitat). Treatments consisted of no aversions (control group), or of averted groups using: (a) electric shock; (b) lithium chloride (LiCl); or (c) both LiCl and electric shock. Steers in the shock group avoided UHQ almost completely, spending significantly less time there than control steers ( P< 0.05), but consumed as much HQ forage from SHQ habitat as control steers. Thus, steers in this group did not become averted to the HQ food in uncued locations. Moreover, location avoidance of steers in this group did not extinguish after shock collars were removed or when location of the UHQ habitat was switched. Steers in the LiCl group consumed significantly less HQ forage than control steers, both in UHQ habitat and SHQ habitat, and spent significantly less time than control steers in UHQ and SHQ habitats. Whereas food aversion remained unchanged during experimentation and extinction trials, location avoidance of steers in the LiCl group rapidly extinguished when location of habitats was switched. Thus, steers averted with LiCl avoided HQ food irrespective of its location or association with visual cues. Steers in the LiCl + shock group almost completely avoided HQ forage in UHQ and SHQ habitats and spent less time than the control steers in both of these

  More info

  The Walker Basin Allotment grazing system in central Arizona is designed to allocate resource use under elk (Cervus elaphus L.) and cattle (Bos taurus L.) grazing. The grazing system was designed to promote biologically acceptable levels of forage use on the half of the allotment scheduled for cattle grazing and to rest the other half by attracting elk to pastures recently grazed by cattle. The objectives of our 2-year study were to determine whether the grazing system facilitated proper forage use as defined by recent forage use and residual stubble height guidelines (i.e., 30 to 40% use and an 8- to 10-cm stubble height) and whether the system rested one half of the allotment from elk and cattle grazing. Mean (+/- SEM) total elk and cattle forage use for western wheatgrass (Pascopyrum smithii Rydb.), the key forage species, was 32 and 61% +/- 7 in 1997 and 1998, respectively; corresponding mean (+/- SEM) stubble heights were 11 and 10 cm +/- 0.6. Mean total cattle and elk forage use in 1998 (61%) exceeded the 30 to 40% use guidelines. However, mean end-of-year stubble height was never below 10 cm. The grazing system did not provide half the allotment with complete rest; elk used all study pastures. Elk use was higher in pastures with heavier tree cover and steeper terrain in both years, regardless of where cattle grazing occurred. Elk grazing patterns were apparently more dependent on tree cover and topography than any changes in forage caused by the grazing system. DOI:10.2458/azu_jrm_v55i4_halstead

  Abstract: A study was conducted in an eight-arm radial maze to determine if cattle with various foraging experiences could facilitate location of feeding sites by other cattle. Heifers assigned as 'followers' (n = 24) were initially trained to expect straw at the end of each arm. Initial training of heifers assigned as 'leaders' (n = 12) differed based on the three following treatments: (1) no-experience, (2) barley in the same two arms, and (3) barley in two arms but locations changed daily. During training, leaders with barley in fixed locations foraged more efficiently by traveling to fewer (P < 0.05) arm ends to find barley than leaders in the variable treatment. After training, two followers were placed in the maze with a leader, and barley was available in two arms. Leaders facilitated the location of barley by followers. In 61% of the occasions that followers first found barley, leaders were at the feeding site. Eighty-one percent of followers later located barley without leaders in the maze. Followers with experienced leaders did not find barley consistently more often than heifers with inexperienced leaders. Cattle can apparently learn feeding site locations from other animals, but additional research is needed to evaluate the behavioral mechanisms that influence social facilitation during foraging.

  Forage use data can help rangeland and wildlife managers make informed decisions. However, managers need to know if forage use techniques that are commonly used to estimate ungulate herbivory under field conditions produce comparable results. The objective of this 2-year study was to directly compare forage use measurements obtained via the paired-plot method and 2 height-weight methods (using on-site height-weight curves and the pre-established United States Forest Service height-weight gauge). In June, July, and October of 1997 and 1998, we measured forage use of western wheatgrass (Pascopyrum smithii Rydb.) by cattle (Bos taurus L.) and wild ungulates, mainly elk (Cervus elaphus L.). On-site height-weight curves and the USFS gauge consistently produced lower estimates (overall means = 8 and 7%, respectively) than the paired-plot method (overall mean = 31%). Height-weight estimates did not differ (P > 0.05) when calculated with either on-site curves or the USFS gauge. Within sampling areas, paired-plot estimates were relatively more precise (mean CV = 63%) than on-site curves (mean CV = 238%) or the USFS gauge (mean CV = 271%). Selective grazing likely contributed to higher CVs for height-weight techniques. Our findings are important for rangeland and wildlife managers because the forage monitoring technique they use may influence the results obtained and, consequently, grazing management and wildlife harvest decisions. Managers should ensure that chosen monitoring techniques provide an appropriate evaluation of management goals and objectives. DOI:10.2458/azu_jrm_v53i5_halstead

  We tested the hypothesis that cattle aided by visual cues would be more efficient than uncued animals in locating and consuming foods placed in either fixed or variable locations within a 0.64-ha experimental pasture. Eight yearling steers were randomly selected and trained to associate traffic barricades and traffic cones with high- (oat-barley mixture) and low- (straw) quality foods, respectively. Initially steers were randomly assigned to 1 of 4 food location/visual cue treatments: fixed locations/with cues (F/C), variable locations/with cues (V/C), fixed locations/no cues (F/NC), or variable locations/no cues (V/NC). High- and low-quality foods and their respective cue (or no cue) were placed in the experimental pasture. Individual animals were allowed to explore the pasture for 10 min twice per day every other day for 1 week. Minutes until feeding, first feed type consumed (i.e., high-quality, low-quality, or no food consumed), animal location and activity (i.e., feeding, standing, or moving), and total intake of high- and low-quality feed were recorded during each 10-min trial. At the end of each week, location/visual cue treatments were randomly assigned to another 2 steers, which permitted an independent test of each animal in each treatment over a 4-week period. Animals in the F/C and V/C treatments took about 2 min to initially locate and consume a food, compared to F/NC and V/NC animals who took nearly 4 and 6 min, respectively. The high-quality food was the first food located and consumed by F/C, V/C, F/NC, and V/NC animals during 79, 77, 67, and 54% of sampling occasions, respectively. Cued animals typically spent more time feeding (P=0.0004) and less time standing (P=0.005) than uncued animals. Cued animals had a higher mean intake than uncued animals of high- (P=0.001) and low- (P=0.04) quality food. Mean high-quality intake for F/C, V/C, F/NC, and V/NC treatments was 266, 245, 214, and 126 (+/-22) g, respectively; mean low-quality intake for the same treatments was 36, 32, 12, and 10 (+/-10) g. Cued animals also consumed more food per distance traveled than uncued animals (P=0.005). Animals located food quicker (P=0.03) and consumed more high-quality food (P=0.02) when food locations were constant than when they were variable. Our data strongly indicate that cattle can learn to associate visual cues with disparate food qualities and use this information to forage more efficiently in both fixed and variable foraging environments.

  Abstract: The objective of our experiment was to determine if the application of two deer repellents to six grape cultivars (Vitis vinifera L.) caused significant phytotoxic effects, production losses, or altered the sensory characteristics of wine. We evaluated fifteen single vine plants from six different cultivars in a randomized block design that included the two repellent treatments and an untreated control. During spring 1997, we applied repellents biweekly from budbreak until flowering (2 Apr. to 14 May). Plantskyyd was applied more frequently than recommended by the product label (for trees) due to rapid emergence of unprotected shoot growth in vineyards. Hot Sauce and Plantskydd caused some initial minor phytotoxicity during 1997, however, the yield and phytotoxicity of treated plants were similar to controls by harvest. A panel detected a significant difference in the color, aroma, or taste of 'Chardonnay' wine made from grapes treated with repellents compared to wine made from untreated control grapes (P = 0.001 for Hot Sauce; P = 0.05 for Plantskydd). We conclude that Hot Sauce and Plantskydd did not cause serious production losses or phytotoxic effects for the six cultivars treated. However, both Hot Sauce and Plantskydd significantly altered the sensory attributes of Chardonnay wine, which may preclude the use of chemical repellents in wine grape vineyards under the experimental conditions applied in our study.

  Abstract: We determined the cattle distribution patterns of dams (and foster dams) and their offspring while grazing a 1030 ha (about 3 km by 5 km) allotment during the summers of 1990-1993. Our primary objective in this 4-year field study was to determine whether yearling and adult offspring (and foster offspring) would return to the initial locations and associated habitat types that they were exposed to by their dams (or foster dams) early in life. We observed the dams' offspring for four consecutive summers (1990-1993) and the foster-dams' offspring for 3 consecutive summers (1991-1993). Cross-fostering was conducted to learn the relative importance of natural dams vs. foster dams as social models in influencing distribution patterns of offspring. Offspring were reared mostly in two different locations on the allotment by their dams or foster dams. Centroid analyses indicated that offspring in all 4 groups remained near the general location where they were reared as calves when they returned to the allotment as older animals (mean 0.5 to 1.2 km from dams' or foster dams' centroid). Peers apparently attenuated the dams' (and foster dams') influence on location and habitat use when offspring were yearlings. The effect of peers was manifested by an increase in distance from dams' or foster dams' centroid, and by a higher association index among yearlings, both of which reflected the collective experiences of offspring in the peer groups. Drought weakened the dams' and foster dams' influence on location and habitat use as water became scarce near their centroids, but drought amplified the dams' and foster dams' influence when water was not limited near their centroids. By the final year of the study, offspring in 3 of the 4 groups monitored were within 0.7 km from the dams' or foster dams' centroid (offspring in the fourth group were within 1.1 km from the foster dams' centroid). Collectively, our results suggest that experiences early in life affected cattle distribution, and that distribution at any point in time was a 'snapshot' of ongoing behavioral changes that were developing according to each individual's antecedent experiences and current environmental and social conditions. These results support the 'working hypotheses' that herding, selective culling, and water and shade development are important management techniques that can enhance dispersion and decrease use of sensitive areas on rangelands (e.g., riparian areas).

  Abstract: Numerous studies suggest some cows use certain areas (e.g. riparian habitats) more than others (e.g. uplands), but the research generally has been based on observations of small numbers of animals or on general inspections of entire herds. Consequently, it is not known if individual animals differ in home range (HR) and habitat use (HU) or if behavioral characteristics are a valid selection tool to decrease cattle use of riparian habitats. We conducted field observations of the differences in HR and HU among adult cows on summer range in Idaho. We located 116 cows on 4970 occasions during 1990, and 87 cows on 3995 occasions during 1991. Individual cows occupied one of four HR areas, and the majority (78%) showed high consistency in HR, despite drought, ad hoc management procedures and occasional herding. Thirty-three percent (n = 29) of the 87 animals monitored during 1990 and 1991 exhibited total HR fidelity between years, whereas 45% (n = 39), 18% (n = 16) and 3% (n = 3) of the animals differed slightly, moderately and substantially in HR use. All cows tended to shift their activities (i.e., centroid) to the south, apparently in response to decreasing water availability between 1990 and 1991. Cows in the four HR groups differed in the degree to which they foraged and rested in riparian and upland habitats, largely depending on the physical characteristics of the HR area. Given the high degree of home range fidelity in our study and those of others, we submit that selective culling may effectively change cattle distribution and decrease the use of riparian areas.

  We evaluated fecal nitrogen (FN) and fecal phosphorus (FP) concentrations as indicators of different dietary nitrogen (DN) and dietary phosphorus (DP) levels fed to 11 penned, white-tailed deer does (Odocoileus virginianus) during summer 1985. We fed deer pelleted rations containing 2 levels of DN (2.64 and 1.18%) or DP (0.49 and 0.30%) during 2 consecutive, 16-day trials. We collected fecal pellets from each animal during the last 6 days of each trial. Pooled mean FN concentrations for corresponding high and low DN levels were as follows: total FN = 2.26 and 1.45% (P = 0.003), neutral detergent FN = 0.60 and 0.39% (P = 0.019), and metabolic FN = 1.67 and 1.06% (P = 0.001). Pooled mean FP concentrations for corresponding high and medium DP levels were as follows: total FP = 1.23 and 0.44% (P = 0.002), neutral detergent FP = 0.12 and 0.10% (P = 0.022), and endogenous FP = 1.11 and 0.33% (P = 0.002). Under controlled conditions FN and FP concentrations can be used to discern relatively large differences in DN and DP levels of whitetailed deer. J. WILDL. MANAGE. 54(3):383-389 Nutrient levels of hand-collected forages have been used as indicators of dietary quality (Cook 1964), but this is generally an unreliable method for determining diet quality of free-ranging ungulates (Theurer et al. 1976) due to the apparent ability of ungulates to select the most nutritious forage available (Swift 1948). Esophageal fistulization is usually impractical for studying diet quality of free-ranging wild ungulates (Leslie and Starkey 1985) and, moreover, is unsuitable for DP assessment due to salivary phosphorus (P) contamination (Holechek et al. 1985). Blood samples require manual restraint or death of animals and, given the complex effects of homeostatic regulation of mineral metabolism, blood P concentrations may not be sufficiently sensitive to assess P status (Underwood 1981). The use of fecal nutrient levels to study diet quality may be a feasible noninvasive alternative to other techniques that require disturbance, stress, or death of wild ungulates (Leslie and Starkey 1985). Researchers have used fecal nutrient levels to predict dietary nutrient levels in elk (Cervus elaphus) (Mould and Robbins 1981, Leslie and Starkey 1985), black-tailed deer (Odocoileus hemionus columbianus) (Leslie and Starkey 1985, Mubanga et al. 1985), white-tailed deer (Jenks et al. 1989, Leslie et al. 1989), moose (Alces alces) (Leslie et al. 1989), and domestic livestock (Belonje and Van den Berg 1980a,b; Holechek et al. 1982, 1985). The advantages (Leslie and Starkey 1987) and disadvantages (Hobbs 1987) of FN as an indicator of DN in free-ranging deer diets have been discussed, but little controlled research has been conducted to determine the utility of using fecal indices for nutrient assessment of wild ungulate diets, particularly for white-tailed deer. Leslie and Starkey (1987) argued for continued research toward refining the use of fecal indices to measure the quality of wild ungulate diets. We conducted a controlled study involving 2 consecutive feeding trials to determine whether FN and FP concentrations could be used to detect differences in DN and DP levels fed to penned, white-tailed deer does.

  The GAP analysis (A Case of Benign Neglect: Knowledge gaps about sustainability in rangelands and pastoralism) points to several gaps that are relevant to the US, Canada and Mexico. North American rangelands span the ecological continuum of polar to hot deserts and arid to humid climates that exhibit highly variable ecological and forage production potential across time and space. Although there is a great deal of rangeland research, extension, and inventory capacity in all three countries, a weak link is the dissemination of information to North American pastoralists (conventionally referred to as ranchers or producers). Although the extension system in the US and Canada are similar, there are distinct differences. Public lands in the US are managed at the national level by federal agencies (e.g., Bureau of Land Management and Forest Service) while private land management assistance is provided by the Natural Resource Conservation Service. In Canada, Crown land is managed by departments within each province and there is no national extension service. In Mexico, the majority of the lands are managed by local communities or ejidos, 15% are privately owned and managed and the remaining 5% is government owned. The three countries support national research organizations and have a well-developed system of colleges and universities that have range management or related disciplines containing staff that specialize in teaching and/or research (and cooperative extension at land grant universities within the US). All three countries must attempt to bridge gaps between an urban industrial society that is increasingly disconnected from extensive agricultural production on rangelands. Promoting ecological goods and services provided by rangelands is a relatively new paradigm for US, Canadian and Mexican research and extension. During the IYRP, the focus in the US, Canada and Mexico is likely to be in 2 directions; providing North American pastoralists/ranchers with the social license to continue to ranch or farm while educating the massive urban population about the sustainability, multiple uses, and benefits of ecological services produced on rangelands and native grasslands.

  More info

  Course Objectives: To build an understanding of the tools, concepts, and thought processes relative to livestock grazing in riparian areas so that participants will be able to work with other individuals, groups, and agencies to develop and implement successful grazing management strategies. Participants learn to develop riparian resource objectives and design grazing management strategies that are practical and foster sustainable conditions. Collaborative planning, focused monitoring, and adaptive management are emphasized, along with success through operator commitment. Given an actual livestock operation situation, participants will be able to provide grazing management alternatives to achieve riparian objectives. Target Audience: Livestock producers, agency personnel, and others who are involved with planning, managing, or evaluating riparian grazing systems. Instructors: A multi-disciplinary team of instructors including experts from the National Riparian Service Team will lead this free, three-day training that encompasses in-classroom sessions paired with daily field workshops.

  As 1st Vice President of SRM, I was part of the SRM Executive Officers Team which consisted of myself; 2nd Vice President Barry Irving; Young Professional’s Conclave President Rory O’Connor; and Policy and Public Affairs Committee Vice Chair Shelly Wiggam. We took part in two days of meetings with industry partners, fellow professional societies, agency leads and Administration officials. This year’s fly-in focused heavily on the number of trainings, workshops and partnerships SRM is currently engaged in and how to best expand their reach and impact to other industry and agency stakeholders. Additionally, the fly-in served to highlight several key issues, including: ongoing work to establish an International Year of Rangelands & Pastoralists; relaying the importance and variety of symposia and workshops taking place at the 2017 SRM Annual Meeting; SRM’s continued commitment to youth development and integration of young professionals into the discipline; and addressing new issues that will face the Society and its members in the years to come.This year’s fly-in followed on the success of the same event the Leadership Team attended in DC in 2015; ongoing partnerships were strengthened, while new and potential projects and issues to engage on were presented. Some highlights of our meetings are summarized below by SRM Deputy Director, Kelly Fogarty including: SRM worked closely with the Sage Grouse Initiative (SGI) to highlight their successes and work done on the issue; the effort resulted in a sponsored edition of Rangelands and a sponsorship for the 2017 Annual Meeting, plus a specific SGI workshop. NRCS Chief Weller asked SRM to expand on this effort to include the lesser prairie chicken. Additionally, the Chief asked SRM to include the “certainty” initiative taking place in the Southwest, stressing the need to publicize the effort to land owners and users as a tool providing assurance and relief to those who commit to conservation plans in regions affected by species listings. Both issues are in need of promotion and attention, the Chief asked SRM to lead on both issues and highlight the work being done and ways by which land owners, users and managers can engage. SRM conducted a high-level meeting with Secretary of Agriculture Tom Vilsack’s Chief of Staff Karla Thieman. SRM stressed the importance of agency participation at Annual Meetings and the number of initiatives and educational opportunities available to agency employees. Also highlighted was the recent formation of the SRM Diversity Taskforce. This effort was received well by many in D.C., specifically at USDA in which the issue has been a key focus of Secretary Vilsack’s tenure. The work being done to broaden this effort to young professional recruitment at the upcoming St. George meeting was also referenced. 2019 Farm Bill: SRM is currently engaged in a coalition focused on invasive species and their representation in the next Farm Bill. SRM provided input on terms currently included in the effort, such as “targeted grazing” and is committed to providing additional feedback and expertise on this issue as it moves forward. Inter-agency meeting: Once again, SRM brought together range staff leads from USFS, NRCS, and BLM for a joint meeting focused on SRM’s current work and projects. This meeting will expand next year to include range staff leads from U.S. Fish and Wildlife Service and the National Park Service. International Year of Rangelands & Pastoralists: The effort to establish this designation remains active. SRM met with multiple individuals close to this issue and effort and will be reaching out to new contacts in the months to come. Professional Societies: Cross-membership promotion: SRM is currently working with the Society of American Foresters and The Wildlife Society to draft Memorandums of Agreement focused on encouraging mutual benefits between the societies achieved through joint membership opportunities and benefits, attendance at each other’s Annual Meetings at member-cost, and joint committee participation and communication. SRM presented draft MOAs to both societies and will continue to explore these options. The SRM delegation followed the following agenda for their visit, each meeting is noted with the issues and priorities discussed, you can see pictures and recaps from all of the meetings on SRM’s Facebook page:THURSDAY, AUGUST 11th: Inter-Agency Meeting: USFS, NRCS and BLM at USFS Meeting with NRCS Chief Weller, presentation of “Trail Boss” Recognition Meeting with Karla Thieman, Chief of Staff to USDA Secretary Vilsack Meeting with David Gagner, Senior Director, Government Relations, National Fish and Wildlife Foundation Dinner with Society of American Foresters Staff and Executive Officers: Matt Menashes; John Barnwell; Clark Seely; Fred Cubbage; Ed Shepard; Bob AlvertsFRIDAY, AUGUST 12th Meeting with National Park Service: Brian Carlstrom, Deputy Associate Director for Natural Resource Stewardship and Science; Jennifer Wyse, Senior Advisor and Legislative Liaison for NRSS (The Natural Resource Stewardship and Science Directorate) Meeting with Krysta Harden, Vice President of Public Policy & Chief Sustainability Officer (CSO) Meeting with Scott Cameron; Reduce Risk from Invasive Species Coalition Meeting with Maryam Niamir-Fuller; re: establishment of an International Year of Rangelands Lunch meeting with The Wildlife Society; Ken Williams, Executive Director and Keith Norris

  Ten years ago, the Rangelands Partnership (RP), an initiative of 19 western land grant universities including the University of Arizona (UA), developed a series of webpages and educational resources on public land grazing issues, including NEPA. These resources were made available via the Global Rangelands/Rangelands West websites. Over the last decade, the ecological, economic, and social debates surrounding these issues have changed as has our understanding and management of public lands grazing. In response, our team is developing a new collection of online resources to provide up-to-date information to producers and the public. The new topic page features improved design and delivery of information using videos, images, figures, and other multimedia. This poster describes the activities and tasks accomplished thus far, including: 1) Conducting a comprehensive review of the current public lands topic on the Global Rangelands/Rangelands West websites, 2) Completing research for updating topics using current science communication approaches and tools, 3) Coordinating with web designers to develop a “site map” plan to link content into a “learning module” design, 4) Conducting video interviews with extension and agency personnel, and ranchers to demonstrate how public land laws and policies impact the livelihoods of those who manage livestock on public lands, 5) Carrying out peer review of new materials and resources by RP members and Arizona Cooperative Extension faculty (on-campus and in several Arizona counties) to ensure the content brings science to bear on real world problems, 6) Rigorously testing the new web design for utility and navigation, and 7) Announcing the availability of new resources through social media, newsletters, and conference activities. In addition to the poster, we will have laptops available to allow conference participants to explore the new website.

  The goal of this 1-year project is to create a multimedia educational program on the theme “grazing on public lands”, with special focus on the NEPA process on rangelands. The project involves a synergistic team of county and campus rangeland ACE professionals and students, the CALS Communications & Cyber Technologies (CCT) unit, the UA Technical Team for the RP, personnel and students affiliated with the UA Natural Resource Users Law & Policy Center (NRULPC), and key Arizona stakeholders such as ranchers, county extension personnel, and public land managers employed by federal agencies. We acknowledge the Extension Strategic Initiative Program (ESIP) for providing funding for this project.Ten years ago, the Rangelands Partnership (RP), an initiative of 19 western land grant universities including the UA, developed a series of webpages and educational resources on rangeland subjects such as the role of NEPA on public land grazing issues. These resources were made available via the Global Rangelands/Rangelands West websites. In the time since the original summaries were developed, the ecological, economic, and social debates surrounding the issue have changed as has our understanding and management of public lands grazing. In response, our team is developing a new collection of online resources to provide up-to-date information to producers and the public. The new site will feature improved design and deliver information using videos, pictures, figures, and other multimedia.

  The noxious weed problem in the western United States has been described as, a biological forest fire racing beyond control because no one wants to be fire boss. Indeed, when small weed infestations are left unchecked, they can grow exponentially and spread across the land much like a slow-moving biological wildfire. However, land consumed by fire usually recovers and is often more productive than before the fire occurred. On the other hand, land consumed by noxious weeds may be irreversibly changed and never again reach its full biological potential.

  Rangeland and livestock management in the southwestern U.S. presents many formidable challenges. Environmental regulations, cattle prices, and drought are just a few factors that contribute to the management challenges of the range-livestock industry. Among them, drought may be the least controllable or predictable variable. This publication discusses how to prepare for drought in southwestern U.S. Topics include principles of drought and range-livestock management, management before drought, management during drought and management after drought.
