Precision conservation—projects at the right place, the right scale, the right size, the right time, and making sure they are working—is going to redefine how landscape conservation is approached. Instead of sweeping acquisitions or all-encompassing legislation, we can use the latest high-resolution datasets to conduct advanced geospatial analysis that allows us to better target and implement on-the-ground a...Learn More

Click the map below to launch the web application. Here you can view enhanced flow paths and high-resolution buffer data, and download flow path intermediate datasets by hydrologic unit code (HUC): flow accumulation, flow direction, and hydro-conditioned digital elevation models (DEMs).
Scroll down to download enhanced flow paths, buffer data (35′ or 100′ buffer zones divided into 12 or 3 land cover classes), and buffer summary PDF reports available by county. Click on the desired county and click the links to download the data.
Data downloads last updated June, 2018.
Click on a county to download land cover data in the 35′ or 100′ buffer zone, or enhanced flow paths. Downloads are zipped rasters (.tif). Unzip and view in ArcGIS Desktop. Buffer summary reports for 35′ and 100′ buffer widths are available as PDFs.
