Between September and November each year, nearly the entire world population of Pacific black brant (Branta bernicla nigricans) stages at Izembek Lagoon and surrounding estuaries (hereafter: Izembek Complex). The Izembek Complex is a unique area of protected brackish waters, supporting one of the world’s largest eelgrass beds and a diverse array of wildlife. The Alaska Fall Brant Survey has been conducted annually since 1976 in late-September through October, to provide an index of abundance for the entire post-breeding Pacific black brant population (Branta bernicla nigricans), while secondarily, providing annual fall population indices for cackling geese (Branta hutchinsii), emperor geese (Anser canagicus), and...

The Alaska Trumpeter Swan Survey was an aerial survey conducted by the U.S. Fish and Wildlife Service, Division of Migratory Bird Management, Alaska Region (MBM-AK) and partners to monitor the status of trumpeter swans (Cygnus buccinator) in Alaska. It was first conducted in 1968 and then repeated at five-year intervals from 1975 through 2015. The objectives of the survey were to estimate the abundance, distribution (1968–2005 only), and productivity of trumpeter swans in late summer, when the swans were dispersed on breeding territories and cygnets were large enough to be easily counted from the air. Estimates were obtained for the abundance of white swans (swans >1 year old), cygnets, and total swans, as well...

Rainwater Harvesting and Stormwater Research is a priority research area identified by the Arizona Governor’s Blue Ribbon Panel on Water Sustainability, which recommended that universities take the lead to identify regulatory barriers, cost and benefits, water quality issues and avenues for increasing utilization of stormwater and rainwater at the regional, community and individual property level. In an effort to address the priority research area, the University of Arizona will develop a decision support tool to be used by public utilities and agencies to evaluate suitability and cost-effectiveness of rainwater and stormwater capture at various scales for multiple benefits. Data from the City of Tucson, Arizona...

This mapping project was a collaboration among the U.S. Fish and Wildlife Service (Service) and staff from the Arkansas Game and Fish and Natural Heritage Commissions. It provides general information on the potential environmental risk to species of concern and sensitive habitats from proposed wind energy projects in Arkansas. According to the Land-Based Wind Energy Guidelines, environmental risks include direct impacts e.g., collisions with turbines and associated infrastructure, habitat loss or degradation from turbines and infrastructure, habitat fragmentation, displacement or behavioral changes, and indirect impacts e.g., reduced nesting and breeding densities and the social ramifications of those reductions,...

Of the vital rates that determine recruitment, breeding propensity (i.e., the proportion of females that lay at least one egg) and nest success appear to have the greatest influence, but breeding propensity remains poorly studied. The few studies that have been conducted reveal it to be highly variable among years (15–77%), likely in response to environmental conditions (e.g., precipitation and wetland availability), and lower than estimates from other dabbling ducks. Thus, quantifying breeding propensity across the mottled duck range in the WGC and identifying factors responsible for its variation remain high priorities for future investigation. Breeding propensity is also among the most difficult vital rates to...

Our proposal addresses Funding Category Ill by evaluating natural resource management practices and adaptation opportunities. More specifically, our project addresses Science Need #6 to improve monitoring and inventory of watersheds and ecosystems (including invasive species). Our proposed study will occur within the Southern Rockies Landscape Conservation Cooperative (LCC) (upper Virgin River, UT) and the Desert LCC (lower Virgin River, AZ and NVL and therefore will be submitting to both cooperatives. Invasive saltcedar (Tamarix spp.) is the third most abundant tree in Southwestern riparian systems (Friedman et al. 2005). Resource managers must often balance the management goals of protecting wildlife species and...

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...

Annual assessment of nesting populations of geese on the Yukon-Kuskokwim Delta (YKD) provides information for biologists, participants in cooperative goose management plans, and Pacific Flyway technical committees. A ground-based sampling procedure has been used since 1986 to estimate the number of total nests, active nests, and eggs for cackling geese, emperor geese, greater white-fronted geese, and spectacled eiders. Annual information on the size of the nesting population and potential number of young produced contributes long term data needed to understand goose and eider population ecology and better manage these species. The survey has been the primary method of measuring recovery status for the western population...
The Waterfowl Breeding Population & Habitat Survey (WBPHS) has been conducted annually since 1955 (1957 in Alaska) by the U.S. Fish and Wildlife Service (FWS) and Canadian Wildlife Service to estimate the spring abundance of targeted waterfowl species in their principal breeding areas of North America. The survey results are used to establish annual hunting regulations in the United States and Canada, monitor population trends, and inform various conservation and management decisions at the state, flyway, and continental levels.The Waterfowl Program in the FWS Division of Migratory Bird Management-Alaska Region (MBM-Alaska) is responsible for surveying strata 1–12 of the WBPHS during May to June of each year (i.e.,...

Sampling Grassland habitats in Urban, Suburban and Rural areas of Central Texas using a modified GMIT protocol and Data Recorder Protocol provided a baseline of operations and tested various techniques and equipment prior to large-scale implementation. This 6-month effort combined the Urban Monarch project with testing field data collections techniques with those used by several partners (TPWD protocol) interested in determining best practices, tools and methodologies for evaluating and monitoring habitat for monarchs, other pollinators and grassland birds. Tablet data recorders were far superior that other recorders tested, and also were superior to cell phone applications. Several milk weed planted areas were...
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...

From 1995 to 1999, a subset of nest plots were searched twice by field crews to estimate nest detection probability by mark-recapture methods. Over the five years, 30 plots were searched twice and over 2700 unique nests were found. From these data, nest detection probability is estimated using a Huggins-type mark recapture model where individual-level covariate effects of nest and observer attributes were estimated. These estimates are then used to predict nest detection rates in other years based on covariates of nests and observers. Nest detection rates are then applied to annual plot search to estimate nest populations for each species in the sampled area.

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...
A combination of citizen science inventories and expert assessments will be used to collect critical baseline information on known spring and seep resources using the Spring Ecosystem Inventory and Assessment Protocols and adapting them as needed for the unique arid Sky Island ecosystems. The assessment will collect information on channel morphology, riparian and wetland vegetation, water quality, aquatic macroinvertebrates, and wildlife. This information will be combined with historic data from cooperating agencies (Pima County, Santa Cruz County, USFS, NPA, USGS, USFWS, BLM, and AGFD) in a regional, on-line database to provide a landscape level context for managing resources, which was previously unavailable due...

More than 90% of the Pacific population of Steller’s eider (Polysticta stelleri) spends a portion of the fall in Alaska during fall wing molt and staging period, mostly along the Alaska Peninsula. The long-term Steller’s eiders counts from fall emperor goose surveys have shown declines at Izembek Lagoon and Port Heiden and approximate stability at Seal Islands and Nelson Lagoon (1992-2015, USFWS unpubl. data). Spring surveys for Steller’s eiders have been conducted along the north side of the Alaska Peninsula by USFWS since 1992; fall oblique photographic surveys covering the same area began in 2012.Systematic transect-based “overhead” photography is a method proposed for the fall survey and will be used to generate...

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.

The Red River Stakeholder Engagement project’s primary objective was to uncover areas of concern for stakeholders who live, work, and play along the Red River Basin. It examined the complexity of the cultural-geographic landscape across the Red River Basin. By focusing on both the geographic and the cultural, we gain a better understanding of how individuals, communities, and organizations interact with the basin and with one another, how they are currently experiencing changes, and what they perceive a changing climate means for them. This cultural-geographic approach recognizes that stakeholders’ concerns, priorities, and actions likely vary across space-and also vary in their cultural significance. For example,...

Accurate estimation of evapotranspiration (ET) is essential for assessments of water balance and hydrologic responses to forest restoration treatments in uplands adjacent to the Desert LCC. As part of the Four Forests Restoration Initiative, a new paired watershed study is being planned to assess the hydrologic effects of mechanically thinning and restoring a more frequent fire regime to the ponderosa pine forests of Arizona. Water and energy balances will be measured and modeled in these paired watersheds to help inform and better plan for the hydrologic responses of future forest restoration actions. Researchers at Northern Arizona University have collected six years of eddy covariance measurements of ET in the...
