In 2006/2007 the Adobetown Herd Management Area (HMA) was rounded up to bring the HMA to its Appropriate Management Level (AML). Given that the HMA is now at AML, a suite of projects have been identified that will improve wildhorse and livestock distribution, rangeland health, and reduce wildhorse movement outside the HMA. The majority of livestock use in this area includes winter sheep, and water development is lacking throughout the HMA. Six miles of pipeline, a number of short pipelines, troughs and supplies for several water wells are proposed. An existing network of pipelines and troughs could be rehabilitated with the purchase and installation of a large solar pump. Four spring developments and small pits...

We studied the effect of castrating a proportion of the adult males in a feral horse herd to examine any effect on behavior and social associations, particularly in terms of association with mares (i.e., maintenance of a harem group). We conducted this study between 2017 and 2020 at two Herd Management Areas (HMAs) in western Utah, USA: Conger and Frisco. We conducted demographic observations year round at both HMAs to record group composition and foaling rate. We additionally recorded behavioral observations at Conger HMA.

This dataset includes locations of burros between 2016 and 2020 from two study areas where burros were located every 2 hours continuously using GPS telemetry collars for Lotek collars, and every 13 hours continuously for Vectronic Aerospace collars. Location data are from adult female burros, not males. Study areas are the Lake Pleasant Herd Management Area in Arizona, USA and the Sinbad Herd Management Area in Utah, USA. Some burro location data from the Lake Pleasant Herd Management Area were collected by the Arizona Game and Fish Department, covering the same time period and methods as USGS-collected data.

We studied factors affecting separation of feral horse foals from their mothers and foal mortality, including variables such as group changes by the mother and behavior of the foal. We include data on feral horse foals that died or were separated, and their siblings. We conducted this study between 2017 and 2020 at two Herd Management Areas (HMAs) in western Utah, USA: Conger and Frisco. We conducted demographic observations year round at both HMAs to record group composition and foaling rate. We additionally recorded behavioral observations for a subset of foals at Conger HMA annually between March and September. This dataset includes 2 .csv files: Data_foals_dead_separated_siblings.csv - These data contain 52...

This dataset includes a number of datasets collected to assess the potential effects of GPS telemetry collars on free-roaming feral equid species in North America: horses and burros. The behavior dataset (Behavioral_data_collared_uncollared.csv) includes frequency of maintenance behaviors of collared and un-collared horses at Conger Herd Management Area (HMA), and burros at Lake Pleasant and Sinbad Herd Management Areas (HMAs). The dataset also includes data on collar effects to fur and superficial effects observed, showing the count of fur effects (i.e., sweaty neck, indented fur, broken fur) and superficial effects (chafe, wound, or scab) on horses and burros over the time that they wore a collar (Collar_fur_and_superficial_effects_over_time.csv)....
Managers concerned with shrinking habitats and limited resources for wildlife seek effective tools for limiting population growth in some species. Fertility control is one such tool, yet little is known about its impacts on the behavioral ecology of wild, free-roaming animals. We investigated influences of the immunocontraceptive porcine zona pellucida (PZP) on individual and social behavior in bands of feral horses (Equus caballus) in three discrete populations and used 14 hierarchical mixed effect models to gain insight into the influences of PZP treatment on feral horse behavior. A model of body condition was the strongest predictor of feeding, resting, maintenance, and social behaviors, with treated females...

This dataset consists of 1,353 ground observer investigations of mountain lion predation events ("kills") in eastern Nevada, USA, from 2018 to 2022. Over the period of the data collection, we had 29 mountain lions equipped with telemetry collars and we investigated clusters of locations when GPS collar locations were in the same area for three nights -- we used this criteria to identify potential predation events by mountain lions, and then hiked to the GPS cluster location on foot to search for a kill site and to identify the species consumed. Collared mountain lions were both males and females, and species consumed included mule deer, feral horses, bighorn sheep, coyotes, other mountain lions, badgers, beaver,...
