This set of maps shows relative habitat diversity (complexity) as it relates to the number of different dominant cover types are found in 1 hectare, and the number of structural types found in 1 hectare. Component layers are included, as are layers of channel boundaries, reaches, and bottomland kilometers.
thumbnail
This set of maps shows relative habitat quality for snakes that prefer the rocky outside margin of the bottomland area. Component layers (type and count of cover types, distance to bottomland boundary and distance to permanent water) are included, as are associated layers of channel boundaries, reaches, and bottomland kilometers.
This map shows allotments by ownership type, compiled from datasets obtained from BLM and USFS. Also shows current and near-term status and long-term potential for change.
thumbnail
This map shows the potential current distribution of Gunnison sage-grouse, in the context of current and near-term terrestrial intactness and long-term potential for climate change and energy development.

This map shows areas that have experienced fire between 1999 and 2010, including fire severity information where available. Determination of "change" due to fire is not possible due to the lack of highly accurate pre- and post-fire maps of vegetation conditions, and the wide range of possible interpretations of what constitutes a change. Instead, the focus was placed on mapping the location of fires and severity; the overall likelihood of significant change in short term vegetation conditions increases with fire severity.

This map shows average seasonal minimum and maximum flow rates at major gaging stations. The period of record varies for each gaging station; averages were for the entire period of record up to 9/30/2010.

The Virginia Department of Transportation (VDOT) Geologic Sections dataset consists of site-specific, large-scale geologic cross-sections (composite sheets). These sections were acquired from VDOT in order to save them from disposal. There are 5,500 geological profiles created for highway construction projects containing extensive core, auger and split-spoon logs at scales of 1:50 and 1:100 providing a unique record of subsurface geological and geotechnical data along roadways throughout Virginia. The thousands of feet of vertical subsurface data represents millions of dollars of investment in data acquisition by VDOT. The sections are useful as indicators of subsurface geology in large parts of Virginia. ...

This study area consists of a 10-km inland buffer of the U. S. Great Lakes shoreline. Islands within the lakes were included in this invasive Phragmites mapping project where remotely sensed imagery scenes were available.
