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. Originally accredited in 2010, ALT once again had its five year accreditation renewed for the 2022-2027 term. Achieving national accreditation symbolizes a national standard of excellence among the country’s land trusts, and only 30% have achieved this prestigious accreditation status.

The accreditation seal is a mark of distinction in land conservation. It is awarded to land trusts meeting the highest national standards for excellence and conservation permanence. Each accredited land trust completes a rigorous review process and joins a network of organizations united by strong ethical practices. This trusted network of land trusts has demonstrated fiscal accountability, strong organizational leadership, sound transactions and lasting stewardship of the lands they conserve.
