Protected Open Space for the DVRPC Region as of 2016. DVRPC maintains an inventory of protected public and private open space in the Delawanre Valley. The inventory tracks all publicly-owned open space, preserved farmland, and non profit protected open space. State, county and municipal programs preserve farms by purchasing development rights with public funds. Non-profits (land trusts and conservancies) protect privately owned open space lands by purchasing easements or by acquiring land outright with a combination of public and private funds.
