The National Conservation Easement Database (NCED), clipped to the boundary of the Southern Rockies LCC. Some of the private easement data in the NCED is not listed in the USGS Protected Area Database (PAD-US), so the two data sets can be used in combination. The entire dataset is available for download from the NCED website. The website's data can also be queried and viewed through an online map viewer.
From metadata: the National Conservation Easement Database (NCED) is a collaborative venture to compile easement records (both spatial and tabular) from land trusts and public agencies throughout the United States in a single, up-to-date, sustainable, GIS compatible, online source. The goal of the NCED is to provide a comprehensive picture of the privately owned conservation easement lands, recognizing their contribution to America's natural heritage, a vibrant economy, and healthy communities. Conservation easements are legal agreements voluntarily entered into between landowners and conservation entities (agencies or land trusts) for the express purpose of protecting certain societal values such as open space or vital wildlife habitats. In some cases landowners transfer "development rights" for direct payment or for federal and state tax benefits.
