Abstract
  • Wildlife managers often use species distribution models (SDMs) as an initial tool in conservation planning. Managers and researchers have made efforts to model the habitat and distribution of pygmy rabbits (Brachylagus idahoensis) across their historic range since the species was proposed for listing under the Endangered Species Act (USFWS 2003). Pygmy rabbits are sagebrush-obligates patchily distributed across the western United States (Green and Flinders 1980). Habitat relationships for habitat specialists like the pygmy rabbit are believed to be relatively consistent throughout their geographic range. However, appropriate spatial and temporal environmental variables at local, regional, and range-wide scales are often overlooked (Wheatley and Johnson 2009, McGarigal et al. 2016). Numerous regional and range-wide pygmy rabbit distribution models have been developed using various methodologies, environmental variables, and thresholds, resulting in predictive distribution maps that range in accuracy and usefulness. Environmental variables, such as climate or vegetation, limit species distributions at broad spatial and temporal scales (1st and 2nd order selection) (Johnson 1980). In contrast, fine-scale resource selection (3rd and 4th order) tends to be limited by local community interactions (e.g., forage availability, dispersal, predation, and competition) (Johnson 1980). For instance, the species distribution of the pygmy rabbit appears to be limited by climate, phenology, soils, and vegetation at the landscape or range-wide scale (Smith et al. 2021). Whereas dispersal, predation, and specific vegetation and soil characteristics drive resource selection at finer scales (3rd and 4th order). Integrating relevant scientific research into future pygmy rabbit modeling efforts can assist wildlife managers in focusing conservation efforts. To assist in future modeling and conservation efforts focused on pygmy rabbits, I created an annotated bibliography focused on 1st through 3rd order habitat selection. I framed the initial search using established methods utilized by the U.S. Geological Survey (USGS) (Carter et al. 2018, 2020, Kleist 2022), and then narrowed my results to include research focused on previous modeling efforts, and 1st through 3rd order habitat selection. The initial search results included over 2,000 products, which were then narrowed down to 41 peer-reviewed journal articles or technical reports. I summarized each product, focusing on habitat selection and environmental variables that could be modeled at a 30 m or greater scale. I also compiled a list of published pygmy rabbit SDMs and habitat models, the broad category of environmental variables modeled (Table 1), potential data sources, and available resolution of environmental variables used in future modeling efforts (Table 4).
