Houston Wilderness promotes, protects and preserves the 10 ecoregions in multiple counties around Greater Houston through facilitation of large-scale environmental policy initiatives including: 1) the 8-county Gulf-Houston Regional Conservation Plan (RCP), 2) the collaborative Super Trees for Sustainability Initiative that incorporates the 25-mile Houston Ship Channel (HSC) TREES Program, the multi-county Riverine Targeted-Use-of-Buyouts (TUBs) Program, and multiple targeted urban forestry projects in EJ communities around Greater Houston, 3) the Southeast Texas Native Seed Mix Initiative, and 4) the Collaborative Grant-Organizing Program. We work with multiple stakeholders on collaborative environmental policy, funding, education and on-the-ground ecosystem services.
