Evaluation Of Aerial Strip-Transect Surveys For Estimating Average Use By Waterfowl Wintering At Sequoyah National Wildlife Refuge, Oklahoma, 2012-2014.

Paige Schmidt, PhD & Dustin Taylor
In 2012, we evaluated aerial transects (strip transects) for surveying wintering waterfowl at Sequoyah NWR and the landscape immediately surrounding the refuge. In surveying the landscape around the refuge, we attempted to capture the area used by waterfowl making daily commute flights to forage off refuge (Johnson et al. 2014). In total, we surveyed 26,895 hectares, with the 8,464.8 hectare refuge comprising 31% of the survey area. The survey consisted of 33 transects that ranged...

San Bernardino National Wildlife Refuge: Vegetation and Landcover Mapping Using Object-Based Image Analysis and Open Source Software

Bethany DeRango
In May, 2014, staff at the San Bernardino National Wildlife Refuge (SBNWR) requested the production of a vegetation map to document the ongoing restoration of the refuge. Utilizing object-based image analysis (OBIA) a 9 class vegetation map was produced. This was a piloted effort to develop a simple, repeatable and low-cost land cover mapping framework that could be carried out on other refuges. Thus, iterative steps were taken and refined as part of the mapping...

Observations of whooping cranes during winter aerial surveys: 1950–2011.

L.N. Taylor, L.P. Ketzler, D. Rousseau, B.N. Strobel, K.L. Metzger & M.J. Butler
The Aransas-Wood Buffalo population of whooping cranes (Grus americana) declined to near extinction by the 1940s. Starting during winter 1950–1951, annual aerial surveys were conducted to observe and record the number of whooping cranes wintering on Aransas National Wildlife Refuge (NWR) and surrounding areas. This effort resulted in 38,332 observations of whooping crane groups being marked on paper maps between winter 1950–1951 and winter 2010–2011. We digitized those locations by matching the ArcMap 10 screen...

Integrating spatially explicit indices of abundance and habitat quality: an applied example for greater sage-grouse management

Coates, Peter S.; Casazza, Michael L.; Ricca, Mark A.; Brussee, Brianne E.; Blomberg, Erika J.; Gustufson, K. Benjamin; Overton, Cory T.; Davis, Dawn M.; Niell, Lara E.; Espinosa, Shawn P.; Gardner, Scott C.; Delehanty, David J.
This study provides timely and highly useful information about greater sage-grouse over a large area of the Great Basin. USGS researchers and their colleagues created a template for combining landscape-scale occurrence or abundance data with habitat selection data in order to identify areas most critical to sustaining populations of species of conservation concern. The template also identifies those areas where land use changes have minimal impact. To inform greater sage-grouse conservation planning, the researchers developed...

Southwest U.S. Mechanically Treated Chaparral Photo Series

Teresa J Brennan Jon E Keeley
Accurate, complete fuels data are critical for making fuel management decisions and for predicting fire behavior and fire effects. A fuel photo series is a useful reference that allows natural resource managers to quickly quantify fuel and vegetation properties by comparing on site conditions to a series of photos showing a range of calculated fuel loads within a similar vegetative community. While there are photo series available for a wide range of ecosystem types nationwide,...

Shorelines Extracted from Landsat Imagery: Cat Island, Mississippi

Kristy K. Guy
Changes to barrier islands occur at time scales that vary from the few hours it takes an individual storm to pass (Morton, 2008) to the millennia it takes for the geologic evolution of coastal systems to take place. Developing an understanding of how barrier islands will respond to climate change, sea level rise, and major storms over a range of time-scales is relevant to studies of physical, geological, ecological, and societal processes and will help...

Evaluating rehabilitation efforts following the Milford Flat Fire: Successes, failures, and controlling factors Data

Michael Duniway, Emily Palmquist & Mark E. Miller
Uncontrolled wildfire in arid and semiarid ecosystems has become an increasing concern in recent decades. Active rehabilitation of fire-affected areas is often quickly initiated to minimize long-term ecosystem damage. However, the complex soil-geomorphic-vegetation patterns and low and variable moisture conditions in these regions makes restoration challenging. To further inform these post-fire management decisions, we present results from 5-years of vegetation and sediment flux monitoring following the Milford Flat Fire in west-central Utah, USA. Our sampling...

These data are used to provide an independent test of the hypothesis that ammonium derived primarily from waste-water treatment plants was inhibiting phytoplankton uptake of nitrate....

Data for herpetofaunal inventories of the national parks of South Florida and the Caribbean: Volume II, Virgin Islands National Park

J Hardin Waddle, Marquette E Crockett, Raymond R Carthy, Kenneth G Rice & H Franklin Percival
The Comprehensive Everglades Restoration Plan (CERP) requires the use of ecological indicators to measure the success of restoration efforts. The Everglades amphibian community is ideal because amphibians are present in all habitats and under all hydrologic regimes. During Everglades restoration, hydrologic patterns will change and the response of ecological indicators will determine success. Fourteen amphibian species were detected through VES, vocalization surveys and trapping methods throughout the study and the occurrence information collected in this...

This data set contains geographic positioning system locational data for boater access points, use data (i.e. recreational, fishing), water quality measurements (e.g. calcium concentrations, pH), risk assessment data, and other physical attributes (i.e. size, elevation) where available within the Columbia and Snake...

Map of Whooping Crane stopover site use intensity within the Great Plains from satellite telemetered birds, 2010-2014

David Brandt Aaron Pearse
Whooping cranes (Grus americana) of the Aransas-Wood Buffalo population migrate twice each year through the Great Plains in North America. Recovery activities for this endangered species include providing adequate places to stop and rest during migration, which are generally referred to as stopover sites. To assist in recovery efforts, initial estimates of stopover site use intensity are presented, which provide opportunity to identify areas across the migration range used more intensively by whooping cranes. We...
