Vernal or seasonal pools are small, temporary bodies of water that can serve as critical habitat for frogs, salamanders, reptiles, invertebrates, and other species. The first step in developing effective conservation strategies for vernal pools and associated wildlife species is to know where on the landscape these small wetlands exist. Although several several states and organizations in the Northeast region have initiated coordinated vernal pool mapping projects, this information has never been assembled in one place.Currently, the Vernal Pool Data Cooperative (VPDC) consists of over 60,000 vernal pool locations submitted by cooperators representing ten states and two Canadian provinces from Virginia to Quebec’s...

Description: The upper Gila River in New Mexico is one of the few unobstructed rivers in the Colorado River Basin with largely intact native fish populations, including four federally listed and one state listed species.Freshwater systems throughout the West continue to be threatened by human encroachment and water development. Methodologies or decision support tools to evaluate resource management practices that foster an understanding of how fish species adapt to the effects of climate change are critical to future resource management planning.
Tidal marsh habitat is at high risk of severe loss and degradation as a result of human uses, sea-level rise, changes in salinity, and more frequent and extreme storms projected by climate models. Availability of habitat is a prerequisite for long-term viability of marsh bird populations and this has been modeled in a companion California Landscape Conservation Cooperative project (Veloz et al. 2011). However, habitat alone will ensure neither resilience nor recovery of depleted and threatened populations. To provide management guidance to reduce species’ vulnerability and recover depleted populations, we developed interactive population dynamic models for four key marsh species: Black Rail, Clapper Rail, Common...
Meadows delineated in the Sierra Nevada wth refugial status and connectivity rankings–WellConnected (WC), ReallyWellConnected (RC), Stable. Satisfies the delivery of “Sierra Nevada Connectivity Maps” and “Sierra Nevada Meadows Map”. Maps of the Sierra Nevada Meadows designated by their connectivity classification and whether they are expected to have a climate different than historic (1910-1939). We generated maps for modern climate (1970-1999) and four future climate scenarios, broken down into 30 year intervals, in which we assumed connectivity would not change because resistance and conductance surfaces were static. Data for the map are polygon shapefiles of meadows, processed first by buffer and dissolve in...
Coastal ecosystems have been identified by the International Panel on Climate Change (2007) as areasthat will be disproportionally affected by climate change. Recent sea-level rise projections range from 0.57to 1.1 m (Jevrejeva et al. 2012) or 0.75 to 1.9 m by Grinsted et al. (2010) and Vermeer and Rahmstorf(2009) by 2100, which are contingent upon the ambient temperature conditions and CO2 emissions. Sealevelrise projections for San Francisco Bay are 1.24 m by 2100 (Cayan et al. 2008). The expectedaccelerated rate of sea-level rise through the 21st century will put many coastal ecosystems at risk,especially those in topographically low-gradient areas.Sea-level rise response modeling was conducted at 12 tidal salt...
The aim of this USGS program is to provide site specific sea-level rise predictions to land managers through the intensive collection of field data and innovative predictive modeling. In 2009 and 2010, thousands of elevation and vegetation survey points were collected in salt marsh at 12 sites surrounding San Francisco Bay. The elevation data was synthesized into a continuous elevation model for each site, providing land owners valuable baseline data. This site hosts the project report, pages describing each of the 12 marshes visited in this study, and maps and GIS data for all of the marshes including high-resolution digital elevation models.

Rate of global biodiversity loss increased significantly during the 20th century associated with human environmental alterations. Specifically, mismanagement of freshwater resources contributed to historical and contemporary loss of stream-dwelling fish diversity and will likely play a role in determining the persistence of species in the future. We present a mechanistic pathway by which human alteration of streams has caused the decline of a unique reproductive guild of Great Plains stream-dwelling fishes, and suggest how future climate change might exacerbate these declines. Stream fragmentation related to impoundments, diversion dams and stream dewatering are consequences of increasing demand for freshwater resources...

We propose to use long-term fish-population data from a relict reach of the Pecos River, New Mexico to assess population dynamics of imperiled prairie-river minnows, including Arkansas River shiner. Development of viable management strategies requires basic understanding of population ecology. Rigorous, quantitative ecological methods can be used to analyze continuous, long-term demographic data, but such data are rarely available for imperiled, non-game fishes. Data available for the Pecos River provide a unique opportunity to apply quantitative methods to prairie-river minnow conservation and management. Analyses proposed here would determine (1) whether population regulation is density dependent or flow-regime...

The tillage suitability product is a per-crop, per-pixel (30 square-meters) model representation of the predicted probability (0.00-1.00) that an area can support commodity crop development for a suite of crop types commonly grown in the LCD landscape. The values for each grid cell are interpreted as a probability, with any value greater-than 0.50 suggesting an area should be suitable for crop development based on observations of 2.5 million farmed areas around the LCD geography. To demonstrate composite suitability (“tillage”) for all crops, we added the individual probabilities for our modeled from cover classes (cereals, corn, cotton, and beans), which represents the overall proportion of votes for “crop” vs....

These data represent areas defined as large block grasslands according to a model developed by PLJV (McLachlan 2008). The model is based on literature derived Lesser Prairie-Chicken habitat preferences and considers habitat composition within a 2,000 ha area. Any pixel with more than 58% grass, less than 36% cropland, less than 2% woodland/ shrubland, less than 5 % secondary roads, and no 4 lane roads within a 2,000 ha surrounding area is counted as a large block grassland pixel.

This data was collected by the US Fish and Wildlife Service to see if environmental DNA (eDNA) varied across pools and within pools in the Illinois River basin. The data was collected in 2015 from three different habitat types: shoreline, main channel, and bays. The resulting data were then analyzed using an occupancy model.

Riparian Areas is an indicator of the Midwest Landscape Initiative’s (MLI) 2023 Midwest Conservation Blueprint. The Blueprint is a basemap of priority lands and waters for conservation across the Midwest consisting of over 20 social and environmental values representing diverse interests across society. This indicator was chosen as a targetable, important feature of the MLI goals that will be used to track conditions over time and prioritize areas for conservation. Indicators were defined through elicitation and prioritization exercises with federal and state participants. Criteria for the indicators includes 1) actionable, 2) measurable, 3) relevant to multiple groups across the region, and/or 4) representative...
