These data are detections of bison in Grand Canyon National Park made during helicopter surveys between 2019 and 2021, and an aerial infrared imagery survey done in February 2020.

This GIS shapefile, "quantile_bands," is derived from a parent shapefile, "density_contours," which describes 1) a bison study area at Wind Cave National Park, South Dakota, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2019-2024. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the distribution of bison activity within the study area. Each contour encompasses lower-coverage contours: the 75% contour, for example, encompasses the 50% and 25% contours but not the 99% contour. Quantile bands correspond with intervals between contours in "density_contours." Each of the first 4 bands encompasses approximately 25% of bison locations. Percentages associated with contours describe nominal coverage, i.e., quantiles the bands are expected to encompass. Bands comprise a partition of the bison study area and do not overlap. Users are advised that ground conditions within the study area may change over time, leading to changes in bison distribution.

This dataset includes (i) camera-based detection data for nine-banded armadillos (Dasypus novemcinctus) and coyotes (Canis latrans) and (ii) covariates characterizing the environmental conditions at each of 100 sites sampled in the Wichita Mountains Wildlife Refuge during summer 2023.

This dataset includes three datasets collected in 2021 and 2022 to assess the potential effects of bison (Bison bison) herbivory and climate on grassland functional properties throughout semi-arid meadows in Grand Canyon National Park and Kaibab National Forest of northern Arizona. Bison herbivory offtake (utilization) and aboveground herbaceous production are demonstrated in the production offtake dataset titled 'BisonHerbivory_ANPP_Ot.csv'. This dataset includes the experimental treatment variables (Stratum and Treatment) and estimates for seasonal offtake, total annual offtake, total aboveground net primary production, and grazing intensity. Data on herbaceous nitrogen yield provides calculations of percent nitrogen and nitrogen yield for graminoid and forb samples collected from biomass clippings in areas of bison grazing (file titled 'BisonHerbivory_N_Yield.csv'). Meteorological data are presented for seasonal and total annual climate variables including precipitation (measured in mm) and temperature (measured in Growing Degree Days). Climate data is within the file titled 'BisonHerbivory_Climate.csv".

These data represent 2 years of plant clipping data in areas with elk plus bison and areas of elk only in the San Luis Valley of Colorado, USA from 2006-2008. Clipping plots were measured (clipped) in meadow sites, herbaceous riparian sites, and willow communities. We clipped 1/4 m2 (meter-squared) rings inside and outside of 1-m2 grazing cages, as well as within large ungulate exclosures that were 0.04 ha (hectares) in size.

Each of the first 4 bands encompasses approximately 25% of bison locations. Percentages associated with contours describe nominal coverage, i.e., quantiles the bands are expected to encompass. Bands comprise a partition of the bison study area and do not overlap. Users are advised that ground conditions within the study area may change over time, leading to changes in bison distribution.

These data are detections of burros in the Sinbad Herd Management Area in central Utah made during aerial thermal infrared-based distance sampling surveys in December 2015 and May 2016. Burros were detected from a fixed wing aircraft using an infrared camera mounted on the underside of the aircraft. A monitor screen was inside the aircraft, connected to the camera so the observer could look for burros in the monitor. Aircraft flew at 2,000 feet above ground level. These data were collected to estimate the population size of burros in the Sinbad Herd Management Area and to examine effectiveness between helicopter and aerial thermal infrared survey types. To assess performance of the different survey types, data analyses were conducted on both survey types and results were compared to known population size.
