The Heritage Trust is a proud member of the following organizations:
The Land Trust Alliance is a national conservation organization that "works in three ways to protect the places people love. First we increase the pace of conservation, so more land and natural resources get protected. Second, we enhance the quality of conservation, so the most important lands get protected using the best practices in the business. And third, we ensure the permanence of conservation by creating the laws and resources needed to defend protected land over time."
The Washington Association of Land Trusts "works collaboratively to strengthen land trusts ability to conserve land and water for future generations across the diverse landscapes of Washington State."
The Land Trust Alliance created Terrafirma as a charitable risk pool owned by participating land trusts that insures its members against the legal costs of defending conservation. It is available for all Land Trust Alliance member land trusts with conservation easements or fee lands held for conservation. This is the flagship resource to permanently protect conserved lands, and it marks the first time that a conservation group has created a captive insurance service.
The Coalition is a nonprofit citizens group that "leverages public funds for new state and local parks, wildlife habitat, and farmland preservation."
GuideStar USA, Inc. is an information service specializing in reporting on U.S. non-profit organizations. Their mission is "to revolutionize philanthropy and non-profit practice by providing information that advances transparency, enables users to make better decisions, and encourages charitable giving."
