This data layer depicts North Dakota Game and Fish Department Wildlife Action Plan focus areas. Focus Areas typically exhibit unique or easily identifiable differences in vegetation, soils, topography, hydrology or land use. Focus Areas are highly variable in size and often represent an area of native vegetation or a natural community type rare to North Dakota. Most of the 100 Species of Conservation Priority can be linked to Focus Areas. The purpose of the data is to provide a comprehensive list and spatial location of North Dakota wildlife action plan focus areas. This dataset is primarily used as a framework data layer for use in GIS and other mapping applications and does not represent a land survey of the focus...

The Virginia Natural Landscape Assessment (VaNLA) was a landscape-scale GIS analysis that identified, prioritized, and linked important lands to form natural land networks throughout Virginia. Using land cover data derived from satellite imagery, the VaNLA identified large, unfragmented cores, patches of natural land with at least 100 acres of interior cover. Cores provide habitat for a wide range of species, from interior-dependent forest species to habitat generalists, as well as for species that utilize marsh and maritime habitats. The most ecologically significant cores were linked by landscape corridors. Lower-ranked cores and fragments of natural land that intersected landscape corridors were added as corridor...

Estimated number of breeding pairs of Savannah sparrow based on the amount of grass, trees, and/or hay in the landscape. Landscape scale varied from 1/4- to 2-mile radius depending on the species. Pair estimates were calculated for grass patches >=1 ha, extrapolated to 40-ac cells, then smoothed by averaging over a 1-mile radius. Models were based on point count surveys conducted in 2003-2005 throughout the Tallgrass Prairie Pothole Region. Point count locations were stratified by cover type, the amount of grass in the landscape, and USFWS Wetland Management District boundaries. Landcover data were derived from 2000 Thematic Mapper imagery. Grid values = number of breeding pairs per 30-m pixel.

The Washington Connected Landscapes Project: Cascades to Coast Analysis Report is divided into three sections. Section 1 of this report contains four chapters. Chapter 1 provides an introduction to the project and the region. In Chapter 2, we provide an overview of the methodological approaches used to model connectivity across the Cascades to Coast region. This chapter focuses on providing an overview of the approaches and rationale for the decisions we made. The tools and methods used are similar to those used in the WHCWG’s previous work (WHCWG, 2010, 2012), and in related analyses (Gallo et al., 2019). Readers should refer to those reports and the documentation for the tools used (e.g. LinkageMapper; McRae &...

The purpose of this map is to provide a georeferenced characterization of vegetation in the early stages of Euro-American settlement. One of the research uses for the surveys nationally is for presettlement vegetation. This data can be used to analyze presettlement vegetation patterns for the purpose of determining natural community potential, productivity indexes, and patterns of natural disturbance. The area of the original plat maps were townships; use of the data at a larger scale would not be appropriate.In Illinois, the surveys began in 1804 and were largely completed by 1843. The surveyors moved across the state laying out a rectangular grid system, known as the Public Land Survey System (PLS or PLSS). They...

Prioritization for protection of habitat (via acquisition or easements), based on local scale ecological integrity, degree of threats faced, potential conservation opportunities, and conservation value of surrounding landscape. In contrast to ecological integrity ratings; threat, opportunity and landscape rankings are largely based on the range of values of any given indicator across the geography, sorted by quantile. There are some exceptions, particularly for indicators used to develop threat rankings (e.g., urban development risk). EEMS is a tree-based, fuzzy logic modeling system, where output values range from -1 to +1, indicating whether a given output is entirely FALSE or TRUE, respectively. Indicators with...

For the Green River Basin Landscape Conservation Design (GRB LCD) assessment, we mapped the vulnerability of occupied Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus) habitat to climate change for each 12-digit hydrologic unit. Cutthroat trout occupied habitat was mapped from the range-wide status report (Hirsch et. al 2013). Using a vulnerability framework, we defined Sensitivity (S) as the total length of occupied cutthroat trout habitat within HUC12 polygons. The exposure parameter incorporates two climate change metrics, the change in flow timing and change in stream temperature. Exposure is quantified as the square root transformed product of the two climate change metrics. Potential Impact...

Areas identified in the Minnesota Pheasant Action Plan to target habitat enhancement and protection in complexes at least 9 square miles in size where a goal of 40 percent permanent protection can be met within the timeframe of the plan. The complexes identify the best places for pheasant production and focused protection efforts on those areas to create permanent habitat complexes. Ranking of the complexes was based on current conditions. For instance, if a complex is at 38% permanent protection, it scores very high since with only a little effort 40% protection can be achieved, conversely. A place that was 20% scored low. The complexes identify the best places for pheasant production and focused protection efforts...

Conservation priorities have been identified for each river basin at the cataloging unit or stream reach scale and were categorized using two tiers to indicate relative importance when considering the limited resources available for conservation initiatives. The recommendations were developed by Commission biologists through review of their field data as well as data from several agencies and research organizations. The review considered a combination of factors such as the presence of federal- or state-listed species; distribution of priority species; high species diversity; unique habitats, or high-quality habitats in the subbasin; and the importance of the watershed to downstream populations. Priority areas identified...
