Some of the major conservation projects include 118-acre (0.48 km2) Saddle Swamp, 300-acre (1.2 km2) Maury Island Marine Park and 90,000-acre (360 km2) Snoqualmie Tree Farm.
In December 2016, Forterra acquired 376 acres (152 ha) of forest near the North and Middle Forks of the Snoqualmie River, jointly with Washington’s Department of Natural Resources.
