This map shows least-cost corridors and large natural habitat blocks. These blocks and corridors may provide an essential network for various species to disperse through the landscape. Blocks are based on large areas of contiguous natural vegetation cover, and are subdivided by major roads. We connected blocks using sticks (to define a pair of blocks between which to model corridors), and developed least-cost corridors based on a cost surface developed from land cover.

This map shows water-based recreation travel corridors (selected from NHD flowlines), and land-based recreation travel corridors (selected from BLM GTLF within federal / state lands and national trails).

rbison is an R package or wrapper for interacting with the USGS BISON search API (https://bison.usgs.gov/#opensearch). rbison allows users to pull species occurrence data from datasets available from the USGS BISON application, inspect species occurance summaries, and then map species occurance within the US, within the contiguous 48 states, and/or at county or state level. The U.S. Geological Survey's BISON (Biodiversity Information Serving Our Nation - https://bison.usgs.gov) application is a product of the USGS Science, Analytics and Synthesis Program. BISON is an information system that allows users to access, explore, and download species occurrence data (predominantly specimen-based e.g. from digitized museum...

USGS researchers assessed how climate change can affect land cover and flow in river systems, examining a variety of resolutions for detecting and projecting the conditions of aquatic habitats and species.

The USGS and South Atlantic LCC worked with stakeholders and managers across the Southeast to identify and assess landscape-level strategies for conserving multiple species. These strategies incorporated predictions from downscaled climate models, sea level rise, and changes to aquatic and terrestrial habitats.

The Southeastern United States spans a broad range of physiographic settings and maintains exceptionally high levels of faunal diversity. Unfortunately, many of these ecosystems are increasingly under threat due to rapid human development, and management agencies are increasingly aware of the potential effects that climate change will have on these ecosystems. Natural resource managers and conservation planners can be effective at preserving ecosystems in the face of these stressors only if they can adapt current conservation efforts to increase the overall resilience of the system. Climate change, in particular, challenges many of the basic assumptions used by conservation planners and managers. Previous conservation...
