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...

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...
This report summarizes the methods and results of utilizing the Edwards to Gulf Conservation Blueprint to achieve specific tasks for various conservation entities. The goal of this effort is to provide real world examples of the use of our spatial products to ensure that stakeholders understand how to use and incorporate the blueprint into their own decision-making processes. This report covers a suite of demonstration projects that illustrate a variety of tasks likely to be of interest to the broader stakeholder community. These include using the habitat protection rankings to prioritize areas within a predefined focal area within the Edwards to Gulf region (Figure 1), mapping a route of least impact for a proposed...

This project is intended to provide conservation science support across Arizona through development of conservation case studies and synthesis products and support for data entry for listed species in Arizona (the yellow-billed cuckoo). One full-time Research Specialist and one ¼-time student research assistant will synthesize best practices best practices for managing invasive aquatic species and invasive plants in grasslands. 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...
This project will refine the hierarchical prioritization within and across the Texas Native Fish Conservation Areas (NFCAs) for integration into the comprehensive revisions of the Texas Conservation Action Plan in 2025. Research products (SDMs and hierarchical prioritization of NFCAs) will guide efforts that result in long-term focus for management and make the most efficient use of limited conservation resources for maintaining or improving conditions for Species of Greatest Conservation Need (SGCN) fishes. Research products can subsequently be used to support efforts such as: updating Species Status Assessments used to inform revisions of the SGCN and State Threatened and Endangered species lists, refining the...

We created ADAPT to help partners make science-informed decisions related to species and habitat prioritization across the Southwest United States. We used Integrated Nested Laplace Approximation (INLA) to analyze the data at a 1-km resolution. We used climate and land use change data generated from CMIP 6 climate models. Count data were from eBird surveys and converted to presence/absence data for analysis. Our model consisted of fixed effects of elevation, land cover type, and effort with random effects for year and site as well as a spatial random effect. We implemented the effect of relative humidity as a spatially-varying coefficient such that the effect of relative humidity on occupancy can vary at each grid...
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...
This project will evaluate occupancy and habitat relationships at San Bernard NWR. This project will consider several factors that may include prescribed fire, forage conditions, impacts from Hurricane Harvey. The project will build upon previous work funded through Texas Parks and Wildlife Department and the Texas Comptroller’s Office.
Understanding the demographic drivers of reintroduced and translocated populations is critical for the species’ establishment and persistence. Given the large number of resources required to conduct ongoing reintroduction and reinforcement programs, additional information on population responses to management practices could help identify key actions that best benefit a species while ensuring economic feasibility. Integrated population model (IPM) can used to assess and forecast the demographic consequences of different management practices and the interrelationship between management effects, population dynamics, and environmental change. We used an IPM to inform potential impacts of nest management practices and...
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...
