The Rivers and Habitat Open Space Program (WAC 222-23) is available to eligible Washington state landowners who would like to sell a permanent forestland conservation easement to the state.
Two types of land are eligible for the program: 1) forestland habitat critical for state-listed threatened or endangered species (Critical Habitat), and 2) a specific type of river habitat called unconfined channel migration zones (CMZ), which are islands of timber within a river channel that is actively shifting. Since 2002, when funding first became available, the program has protected 1,043 acres of important habitat through 16 conservation easements.
