Group Service Areas

WeConservePA has mapped the service areas of land trusts, watershed associations, environmental advisory councils, and other organizations. We provide basic, intermediate, and advanced pathways for exploring these organizations.

Basic Exploration

Find a Group or groups working in a particular county.

Intermediate Exploration

See the service areas of land trusts or search by address using the land trust spatial database.

See the service areas of watershed associations or search by address using the watershed association spatial database.

See the service areas of environmental advisory councils using the EAC spatial database.

Search for trail groups by trail type (e.g. biking or hiking) using the trail group spatial database.

Advanced Exploration

Conduct advanced analysis regarding the service areas of land trusts, watershed associations, or environmental advisory councils, and their relationships to watersheds, legislative districts, and other geographic features, go to WeConservePA’s Advanced Query app.

Updates to Organization Profiles

Streamside Tree Planting Opportunities and Prioritization for PA

Where is a good place to plant streamside forests to improve water quality? The answer could be “just about anywhere.” But some streamside forests benefit water quality more than others. This project combines high-resolution land cover data with soils, topography, land use, and climate data to evaluate more than 200,000 potential streamside forest planting opportunities across Pennsylvania. View the full report here.

Multi-Resolution Land Characteristics Consortium

Land Cover

The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend based on a modified Anderson Level II classification system. NLCD 2016 represents the latest evolution of NLCD land cover products focused on providing innovative land cover and land cover change data for the Nation. NLCD 2016 offers 7 integrated epochs of land cover for years 2001, 2003, 2006, 2008, 2011, 2013, and 2016. Developed classes in these years are directly derived from and updated following the impervious surface cycle. These products update all previously released versions of landcover products for CONUS (NLCD 2001, NLCD 2006, NLCD 2011). New for NLCD 2016 is the NLCD Land Cover Change Index. The NLCD Land Cover change index provides a simple and comprehensive way to visualize change from all 7 dates of land cover in a single layer. The change index was designed to assist NLCD users to understand complex land cover change with a single product. NLCD 2016 does not yet contain updated products for Alaska, Hawaii and Puerto Rico.
