We authored and adopted our GREENPRINT in 2010; it was later integrated into Allegheny County’s Comprehensive Plan. This document guides our process of identifying and prioritizing Pittsburgh-region green space by examining biodiversity, scenic character, and water management functions. We created a publicly-accessible, browser-based digital Greenprint Planning Tool in 2019 as a supplemental update. It guides not only our conservation work, but also the land use work of anyone with an internet connection and the goal of bettering land use in their community.

National Accreditation

We are a nationally accredited land trust as designated by the Land Trust Accreditation Commission. Accredited in 2010, ALT will hold accreditation status for five years. Beginning in 2015, we began a reaccreditation process, which will conclude in mid-2016. Achieving national accreditation symbolizes a national standard of excellence among the country’s 1,700 land trusts, and only 350 land trusts nationwide have achieved this prestigious accreditation status.
