The Virginia Department of Conservation and Recreation – Natural Heritage Program (DCRDNH) and the Florida Natural Areas Inventory (FNAI) at Florida State University (collectively, Project Partners) were funded by the South Atlantic Landscape Conservation Cooperative (SALCC) in April 2015 to develop ten species distribution models (SDM) of priority at-risk and range-restricted species (Ambystoma cingulatum, Echinacea laevigata, Heterodon simus, Lindera melissifolia, Lythrum curtissii, Notophthalmus perstriatus, Phemeranthus piedmontanus, Rhus michauxii, and Schwalbea americana) for the purposes of incorporating the models and supporting information on the conservation and management needs of the species into the...

How climate constrains species’ distributions through time and space is an important question in the context of conservation planning for climate change. Despite increasing awareness of the need to incorporate mechanism into species distribution models (SDMs), mechanistic modeling of endotherm distributions remains limited in this literature. Using the American pika (Ochotona princeps) as an example, we present a framework whereby mechanism can be incorporated into endotherm SDMs. Pika distribution has repeatedly been found to be constrained by warm temperatures, so we used Niche Mapper, a mechanistic heat-balance model, to convert macroclimate data to pika-specific surface activity time in summer across the western...

Abstract (from http://www.sciencedirect.com/science/article/pii/S1574954115001466): Anticipating the ecological effects of climate change to inform natural resource climate adaptation planning represents one of the primary challenges of contemporary conservation science. Species distribution models have become a widely used tool to generate first-pass estimates of climate change impacts to species probabilities of occurrence. There are a number of technical challenges to constructing species distribution models that can be alleviated by the use of scientific workflow software. These challenges include data integration, visualization of modeled predictor–response relationships, and ensuring that models are reproducible...

This dataset comprises high-resolution geotif files representing various aspects of the ʻākohekohe (Palmeria dolei) potential habitat on the Island of Hawaiʻi. It includes a habitat suitability map showing average suitability scores, a map of homogenous forested areas (HFAs) depicting clusters with consistent suitability scores, and a map of pixel-wise standard deviation across habitat suitability models. These maps were generated through a comprehensive analysis using lidar-based metrics, offering detailed insights into the habitat preferences of ʻākohekohe.

The Nature Conservancy (TNC) has derived climate suitability forecasts for most species of trees and shrubs considered to be ecological dominants of terrestrial Californian habitat types. Our plant projections are compiled as decision support tools to help Conservancy project staff, as well as our external partners, develop the necessary plans, priorities and strategies to successfully adapt to uncertain changes in future climate. In the recently completed Southern Sierra Partnership's 2010 Climate-Adapted Conservation Plan for the Southern Sierra Nevada and Tehachapi Mountains, species and habitat forecasts shown here informed the development of a regional conservation design that explicitly incorporates long-term...
The Desert Tortoise (Gopherus agassizii) species distribution model includes a continuous probability surface from the USGS statistical model completed by Kenneth E. Nussear, Todd C. Esque, Richard D. Inman, Leila Gass, Kathryn A. Thomas, Cynthia S. A. Wallace, Joan B. Blainey, David M. Miller, and Robert H. Webb and a binary layer produced by the Conservation Biology Institute. The binary layer depicts predicted suitable habitat using the equal training sensitivity and specificity threshold (0.506). The binary output was also processed to exclude agriculture, developed, and disturbed areas, based on the DRECP land cover/natural vegetation dataset provided by Todd Keeler-Wolf of the CA Dept. of Fish and Game. The...

Data used in: "Misleading prioritizations from modeling range shifts under climate change" by H.R. Sofaer, C.S. Jarnevich, and C.H. Flather. Breeding Bird Survey data (version 2014.0) for songbirds were summarized over historical (1977-1979) and recent (2012-2014) time periods at routes in the conterminous U.S. Avian occurrence data were combined with information on climate and land cover at each survey route.

Predicted probability of marten year-round occurrence derived from future (2046-2065) climate projections and vegetation simulations. Projected marten distribution was created with Maxent (Phillips et al. 2006) using marten detections (N = 102, spanning 1993 – 2011) and eight predictor variables: mean potential evapotranspiration, mean annual precipitation, mean fraction of vegetation carbon burned, mean forest carbon (g C m2), mean fraction of vegetation carbon in forest, understory index (fraction of grass vegetation carbon in forest), average maximum tree LAI, and modal vegetation class. Future climate drivers were generated using statistical downscaling (simple delta method) of general circulation model projections,...

CBI's DRECP species distribution model for golden eagle (Aquila chrysaetos) is based on expert knowledge of suitable foraging and nesting habitat. The golden eagle expert model includes foraging vegetation within 10 miles of known nests and within 4 miles of potential nesting areas, i.e. places with high ruggedness (Vector Ruggedness Measure > 0.01; neighborhood size = 270m). Foraging vegetation includes: herbaceous cover between 30% and 100%; shrub cover between 10% and 50%; tree cover between 10% and 40%; herbaceous wetlands, herbaceous semi-dry lands, and herbaceous semi-wet areas, (based on Landfire Existing Vegetation Cover, 2008; 30m resolution). The golden eagle model output was resampled from 30m to 270m...

Here we present the map of potential suitable habitat for Nye milk-vetch (Astragalus nyensis). The data indicate both how many models predicted each location to be potentially suitable for the species and the average standardized habitat suitability score for each location.Data are presented at a spatial resolution of 10 m pixels, which was required to harmonize the original model inputs. However, maps of suitable habitat should be used at a resolution no smaller than 360 m (i.e., 36 pixels x 36 pixels), which corresponds with the resolution of the coarsest model input. These data are intended to be used only to target future plant surveys in areas where new occurrences are most likely to benefit future habitat...
