The objectives of this SSP project were to develop a Geographic Information System (GIS)-based habitat model for the state of Louisiana and to develop a tool for evaluating the potential effects of various land-use changes on Louisiana black bears. A habitat model previously developed to assess habitat impacts of Hurricanes Katrina and Rita on the coastal black bears in Louisiana (Murrow et al. 2012) was used as the starting point of the analysis for this study. That dataset was augmented with telemetry locations collected from 1993 to 2010 to extend and modify the original coastal model which was based on the Mahalanobis distance (D2) statistic. The goal was to then use that model to develop an estimator and user-friendly...
The ACF basin, from headwaters in north Georgia, to the Apalachicola Bay and estuary, is a focal geography in the Southeast and provides habitat to a diversity of species, including over 30 federally-listed T&E species, and over 30 species proposed for ESA listing, cross-taxa. Allocation of water for multiple uses in the ACF basin has been contentious for decades (e.g., FL v. GA, SCOTUS ruling issued 27 June 2018. A 4.5 day structured decision making (SDM) workshop with experienced SDM coaches is a necessary component to further ongoing adaptive management (AM) processes in the Apalachicola-Chattahoochee-Flint (ACF) River Basin.
This project directly addresses a recovery action in FWS’s recovery plan for the snail kite (Multi-species Recovery Plan for South Florida - Everglade Snail Kite, 1999), which recommends the development of modeling that can predict the response of snail kites to changes in hydropattern anticipated for specific water management proposals (recovery action H3.1). The proposed real-time models would be a significant first step in completing this recovery action, which specifies modeling that would include “...linkage to apple snail distribution and abundance, vegetation characteristics in the landscape influencing the snail kite’s successful foraging, and linkage of all these factors to hydrology.” In addition, this...
The Black Rail (Laterallus jamaicensis) is the most secretive of the secretive marsh birds and one of the least understood bird species in North America. The Eastern Black Rail (L. j. jamaicensis) is listed as endangered in five states along the Atlantic Coast and is under review for federal listing. Historical population size was likely in the tens of thousands but is now believed to be in the hundreds or low thousands (Watts 2016). Within the United States, Eastern Black Rails breed within three general geographic areas within the United States - the Atlantic Coast, the Gulf Coast and the Midwest-Great Plains. The Atlantic Coast has generally been considered to support the largest breeding population throughout...
