This data set contains genetic information collected from eelgrass (Zostera marina) populations along the Pacific coast of North America from Alaska to Baha California. A total of 447 samples were collected comprising 401 unique individuals (genets) and 46 clones (ramets) from which 10 microsatellite DNA loci were obtained.
The mottled duck, a focal species for the Gulf Coast Prairie Landscape Conservation Cooperative, is one of only a few duck species adapted to breeding in southern marshes. A major part of its population spends its entire life cycle within a relatively small coastal area in eastern Texas and western Louisiana. This is a thriving part of the Mississippi and Central Flyways, two of four major waterfowl migration routes in North America. In recent years, the mottled duck’s habitat and surrounding areas have been compromised by urbanization, agricultural development, and changes to the area’s hydrology affecting coastal wetlands. The latter threat includes the ramifications of climate change, such as sea level rise and...

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...

Sea level rise caused by climate change is an ongoing phenomenon and a concern both locally and worldwide. Low-lying coastal areas are particularly at risk to flooding and inundation, affecting a large proportion of the human population concentrated in these areas as well as natural communities-particularly animal species that depend on these habitats as a key component of their life cycle. While more local, state, and federal governments have become concerned with the potential effects that predicted sea levels will have on their communities and coastal landscapes, more information is needed on the potential effects that changes in sea level will have on coastal habitats and species.

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...
Conserving migratory or wide-ranging species presents considerable challenges, as these individuals move across disparate jurisdictions often crossing international borders among crucial stages of their annual cycle. Within North America, Migratory Bird Joint Ventures (JVs) have established successful partnerships to coordinate the planning and delivery of conservation actions within key regions to benefit migratory bird populations. However, the extent to which local conservation actions influence regional demographics and in turn affect continental population dynamics remains poorly understood. Maximizing efficient use of limited resources to conserve habitats for wide-ranging species has motivated a critical...
The Western Gulf Coast (WGC) provides valuable habitat for migratory and resident waterfowl. The mottled duck (Anas fulvigula), a resident species, is highly associated with coastal marsh habitats and relies on these areas for all of its life cycle needs. Habitat loss and degradation due to urban expansion and other human activities have raised concerns for the WGC mottled duck population. Although other threats such as sport harvest (Raftovich 2011), lead poisoning (Sanderson and Bellrose 1986), hybridization (McCracken et al. 2001), and predation (Stutzenbaker 1988, Moorman and Gray 1994, Durham and Afton 2003) may be additional factors in the overall decline of the population, the disappearance of suitable nesting...

Oyster reefs provide environmental and economic services within the coastal regions of the United States. Mapping the extent of these reefs and analyzing their composition can be highly beneficial for oyster management and restoration projects. The objectives of this research project included examining the feasibility of the use of low-cost side-scanning sonar (LC-SSS) systems and Unmanned Aircraft Systems (UAS) for mapping intertidal oyster reefs at selected sites within the Galveston Bay system, Texas. Two sites in Bastrop Bay and Bastrop Bayou complex were selected following defined criteria that included the existence of intertidal oyster reefs and no aviation restrictions on the operation of UAS.
The goals of this study are to: (1) generate a genetic toolset (80-90 microsatellite loci per species) for long term genetic monitoring of both wild and captive populations of each threatened gartersnake species (THEQ & THRU) that inhabit Arizona and New Mexico; (2) conduct field surveys at Saliz Creek to assess the genetic, demographic, and life history effects of a 2012 wild translocation event for THRU to better assess the strategies of genetic management and success of translocations; (3) conduct targeted surveys for both species at key sites to collect additional samples from geographic gaps and increase sample sizes at previously sampled sites to further evaluate connectivity and genetic diversity of these...

The Comprehensive Habitat Type Dataset was developed by merging NOAA Benthic Habitat Atlas (BHA), Ecological Mapping Systems of Texas (aka Texas Ecological Systems Database, TESD), and National Wetlands Inventory (NWI) data within the study area for the ICF 2012 project (CGP LCC 2012-002 Employing the Conservation Design Approach on Sea-Level Rise Impacts on Coastal Avian Habitats along the Central Texas Coast). BHA data was used to depict mangroves, oysters, and patchy, continuous, and discontinuous seagrass beds where BHA existed within the study area. NWI data was used for all wetland/intertidal environments where NWI data existed within the study area. TESD data was used for all upland environments, and weltand/intertidal...
The Western Gulf Coast provides important habitat for migratory and resident waterfowl. The mottled duck(Anas fulvigula) relies on this region for all of its life-cycle events. Its relatively small population, limited worldwide range, and generally declining population trajectory has earned it a “Red” status on the Audubon WatchList and is a species of concern among state and federal agencies. The Western Gulf Coast (WGC) mottled duck population decline is believed to be primarily caused by the historical conversion and degradation of coastal wetlands and native prairie, and recent declines in cultivated rice. There is general agreement among experts that negative impacts to nesting and brood-rearing habitat are...
Recent geomorphic changes observed along the Pecos River in east-central New Mexico have prompted concern that quality egg and larval fish retention habitat for the federally listed Pecos bluntnose shiner (Notropis simus pecocensis, hereafter shiner) is declining. The U.S. Fish and Wildlife Service (Service) is interested in evaluating current habitat conditions and projecting future trends by conducting a comprehensive and in-depth study of the Pecos River’s fluvial geomorphology and hydrology. The Service has contracted with Tetra Tech for this study and this report documents the second (Phase II) of three phases of the effort. Additionally, it is anticipated that this study will provide a basis for habitat restoration...
The whooping crane is one of the most iconic and endangered migratory birds in the world and the wild population’s wintering grounds and migration corridor overlaps a significant portion of the USFWS southwest region. Rapidly developing wind energy in the Gulf Coast (wintering habitat), East Texas, Oklahoma and Great Plains (migratory habitat) has the potential to impact whooping crane habitat use and shift seasonal mortality. Balancing wind energy with species conservation is also a Regional Conservation Priority. This work will provide information about the potential impacts and mitigations of risks of whooping cranes with energy exploration, development and production activities across their wintering area and...
