- Kings Lake Bog Natural Area Preserve (dnr.wa.gov)
This preserve protects sphagnum bogs and a small “eyelet” pond, which represent ecosystems that are now extremely rare in the Puget Trough. Eyelet ponds are open water areas bounded by a quaking mat of sphagnum peat. The preserve includes populations of few-flowered sedge, a state-listed sensitive plant, plus Hatch’s click beetle and Beller’s ground beetle, both state-candidate animal species only found in very good condition sphagnum bogs.
