This study uses growth in vegetation during the monsoon season measured from LANDSAT imagery as a proxy for measured rainfall. NDVI values from 26 years of pre- and post-monsoon season Landsat imagery were derived across Yuma Proving Ground (YPG) in southwestern Arizona, USA. The LANDSAT imagery (1986-2011) was downloaded from USGS’s GlobeVis website (http://glovis.usgs.gov/). Change in NDVI was calculated within a set of 2,843 Riparian Area Polygons (RAPs) up to 1 km in length defined in ESRI ArcMap 10.2.

Pygmy rabbits (Brachylagus idahoensis) are a Species of Greatest Conservation Need in Wyoming. They are designated as such because they are sagebrush obligates and entrained in the health and intactness of sagebrush steppe landscapes. Southwest Wyoming, where pygmy rabbits occur, has become an epicenter of domestic oil and gas exploration and this activity contributes to loss and fragmentation of sagebrush habitats. This tabular file that was used for analysis contains the following data/information: survey site, plot, and gas field; pygmy rabbit occupancy status; UTM coordinates associated with occupancy (dithered to protect pygmy rabbits from further disturbance); an index value indicating amount of fresh pygmy...
