Park Species Detail: ORNHIC G2G3/S2S3 List 2 (contains taxa that are threatened with extirpation or presumed to be extirpated from the state of Oregon. These are often peripheral or disjunct species which are of concern when considering species diversity within Oregon's borders. They can be very significant when protecting the genetic diversity of a taxon. ORNHIC regards extreme rarity as a significan threat and has included species which are very rare in Oregon on this list.) Cole noted: "This lichen was found only at Cape Disappointment in Washington. Except for one location in OLYM, this is the northern extent of its range on the NW coast. It is associated with [Sitka spruce] forests within a few kilometers of the Pacific Ocean. It is considered rare in Oregon and Washington and it is important to protect the Cape Disappointment population. Management recommendations include restricting foot traffic in areas without trails, minimizing the clearing of shrubs and trees along trails, and generally minimizing human entry into areas with known populations. Existing habitat conditions should be allowed to persist and evolve naturally.", Park Species Data Source: Cole, Carla. 2006. Lichens of Lewis and Clark National Historical Park. Unpubl Report
