Observing and counting bats is extremely difficult. Bats hide during the day, fly in darkness, and most species in the United States (US) become inactive and inaccessible in cryptic hibernation sites for 7-8 months each year. More than 40 different species of bats occur year-round in the US, yet reasonable population estimates exist for very few. Populations of US bats face new and unprecedented threats from white-nose syndrome (WNS) and industrial wind turbines. Like WNS, wind energy development might adversely affect entire populations of bats. Species of bats dying at wind turbines in the greatest numbers rank among the most cryptic, elusive, and poorly understood. Hoary bats (Lasiurus cinereus) compose approximately...

While wildlife species do not respect political boundaries, conservation planning and implementation is often restricted by them. Thus, regionally rare species can be placed in the unenviable position of not being prioritized by any jurisdiction that they inhabit due to competition for scarce conservation resources. A regional conservation framework will enable states to cooperate toward common goals and share the costs and accomplishments of regionally conserving at risk species. However, the development of a regional conservation framework is inhibited by patchy species occurrence data. These data gaps can be informed by species distribution models. This project will compile available mussel data, develop species...
The primary objective is to provide guidance to conservation agencies and programs such as Texas Parks and Wildlife Department, Louisiana Department of Fisheries and Wildlife, U.S. Fish and Wildlife Service Region 2 and 4 National Wildlife Refuges, and U.S. Fish and Wildlife Service Migratory Bird Office Region 2 to focus banding activities (i.e., where and when) and minimum sample sizes necessary to meet harvest management objectives for mottled ducks. A secondary objective is to investigate alternate marking techniques (e.g., PIT tags, NANO tags) to supplement or replace assessments derived from band recoveries. The banding needs assessment will be a two part analysis. The first part will use multi-state simulation...
In Texas, the USFWS is currently reviewing 11 mussel species for ESA protection and several of these species (e.g., Cyclonaias petrina, Texas Pimpleback, and Lampsilis bracteata, Texas Fatmucket) have been the primary focus of controlled propagation by several federal hatcheries. To date, information on genetic diversity within and across known populations for these species is incomplete and so the justification for their controlled propagation is unclear, and a genetic management plan to guide propagation activities does not exist. These unknowns raise serious questions about whether any of the 11 proposed species are truly in need of and would benefit from controlled propagation. The overall goal of this project...
As part of the March 29, 2018 appropriations bills, Congress directed the US Fish and Wildlife Service (FWS) to obtain an independent assessment on the taxonomic status of the red wolf, Canis rufus, and the Mexican gray wolf, Canis lupus baileyi. Currently, the FWS considers the red wolf a valid taxonomic species and the Mexican gray wolf a valid taxonomic subspecies. Both the red wolf and the Mexican gray wolf are listed as endangered under the U.S. Endangered Species Act (ESA; United States Public Law No. 93-205; United States Code Title 16 Section 1531 et seq.). However, there is ongoing debate about their taxonomic status.Major barriers to the capability of FWS to re-establish healthy populations of wild wolves...

Information about the amount of habitat needed to support monarchs and how it should be distributed across the landscape will have direct implications for FWS habitat restoration programs. In the St. Croix Wetland Management District (WMD), this information will inform decision making for prioritizing Partners for Fish and Wildlife Projects on private lands as well as upland restoration efforts on WPAs and partner lands. The monarch information gained from this project will be another piece of the ecological puzzle, in addition to waterfowl, endangered species and grassland bird information for landscape-level restoration projects. In addition, the St. Croix WMD is partnering with the National Park Service, U.S....
Pectis imberbis A. Gray is an endemic plant species native to southern Arizona with fewer than 400 known individuals in existence. A total of 6 putative populations, each consisting of between ca. 10 and 180 individuals, occur at elevations of 1100-1700 m in a variety of habitats, including oak woodlands, desert grasslands, oak savannas, and disturbed areas in Arizona (road cuts, arroyos) (USFWS 2012). In the past, populations were also identified in Mexico (Keil 1978, USFWS 2012); however, Mexican populations have not been relocated in recent years (Keil 1982, Falk and Warren 1994, Sanchez-Escalante 2018a, 2018b). Resurveys of known P. imberbis sites suggest significant decline in abundance over the last two decades...
The purpose of this project is to determine if a newly formed rapid on the Colorado River is acting as a barrier to invasive non-native fish moving upstream from Lake Mead into the Grand Canyon National Park (GCNP). These non-native fish would threaten native desert fishes upstream to include the endangered Razorback Sucker and the Humpback Chub. The project will fill knowledge gaps on fish movement, species composition, and population dynamics in this minimally studied section of the Colorado River, and inform managers on whether active management actions (e.g. native fish translocations; non-native removals) may be required to conserve native fishes in the western Grand Canyon.

This is a grant to support the continuation of the Fishes of Texas Program. Texas Parks and Wildlife Department (TPWD) and their recipient, University of Texas at Austin, manage the Fishes of Texas program and the Native Fish Conservation Network (NFCN). This funding will support staff (i.e., research associate) operations that are required for continued stewardship of these important resources that are utilized by state and federal agencies as well as private and academic institutions. This effort has five main Objectives:For Objective 1, the research associate will compile and collate all research, monitoring, and restoration projects conducted within the 20 Texas Native Fish Conservation Areas (NFCAs) since the...
The mottled duck is a resident dabbling duck that is distributed throughout the western Gulf Coast, primarily in Louisiana and Texas (WGC population), and also in a second population in peninsular Florida (Florida population). Within the WGC, several indices of abundance suggest that the mottled duck has declined over the last several decades, but the ability of many of these indices to detect changes in mottled duck abundance is unknown. Additionally, the surveys often provide different and sometimes conflicting results, causing confusion in interpreting WGC population trends. Also, differences in timing and coverage of surveys further complicate our understanding of the population trend. Overall, none of the surveys...

Lists of species of greatest conservation need (SGCN) are powerful tools for revealing shared conservation priorities, enhancing collaboration, and securing additional conservation funding. In the northeastern US, such a list has served as a foundation for multi-state collaborations for conservation implementation.States in the Southeastern Association of Fish and Wildlife Agencies (SEAFWA) region have identified 6,682 SGCN in their wildlife action plans. Collaboratively developing a more targeted list of regional SGCNs will reflect shared conservation values and stewardship responsibilities, encourage cross-state work on those priority species, and substantively contribute to realization of the Southeast Conservation...

The recipient will work collaboratively with Arizona Game and Fish Department and FWS to identify shared species of concern and develop useful synthesis products (case studies and publications). One student Research Assistant will be tasked with increasing communication across FWS programs...
Non-native crayfish threaten native aquatic and semi-aquatic species via modification of aquatic habitats and food webs, and via depredation and competition. In Arizona and New Mexico, management of crayfish is challenged by a paucity of knowledge about factors governing their distribution and population dynamics in space and time. Virile (Faxonius virilis) and red swamp crayfish (Procambarus clarkii) have been documented in at least 22 of 84 HUC8 watersheds within the Lower Colorado River Basin, largely through opportunistic surveying efforts. However, systematic population surveys conducted across key environmental gradients are needed (1) to identify the environmental conditions that predict occupancy, local...

Formed in 2007, the Washington Wildlife Habitat Connectivity Working Group (WWHCWG) is an open collaborative science-based effort to produce tools and analyses that identify opportunities and priorities to provide habitat connectivity in Washington and surrounding habitats (https://waconnected.org). The WWHCWG began with a Statewide Habitat Connectivity Analysis, which highlighted several regions of the state that would benefit from finer-scale analyses. The group has since conducted analyses across many of those regions. The US Fish and Wildlife Service provided funding to develop habitat connectivity models for one of the remaining regions–Washington’s Cascades to Coast region. The goal of this project was to...

Longleaf pine (Pinus palustris) ecosystems in the southeastern United States have declined substantially from an estimated 92 million acres in the pre-Columbian time period to 4.3 million acres at present, largely due to agricultural conversion, urbanization and replacement by other forest types, notably loblolly pine (Pinus taeda). The open landscape character of longleaf pine ecosystems is characterized by a lower carbon stocking and prairie-like understory dominated by grasses and low woody vegetation . Lower carbon stocking combined with greater drought tolerance in longleaf pine suggest that longleaf pine stands generally consume less water relative to loblolly pine and slash pine dominated stands. The...

This project builds off an ongoing effort to develop a suite of spatial products intended to assist regional stakeholders in planning and delivering conservation services (Tarbox et al. 2018c). The preceding project has been conducted in a participatory manner, with extensive stakeholder engagement and feedback. Upon completion, the spatial tools that comprise the conservation blueprint will be made accessible on ScienceBase, along with extensive documentation. The proposed project will make potential end users familiar with how these tools were developed, how they work, and how to best use them to guide their decision-making processes. Due to the complexity of some of the tools, intensive meetings and workshops...
