Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Pacific Reedgrass - Pacific Silverweed - Baltic Rush Salt Marsh
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is an estuarine high intertidal marsh that occurs along the outer coast of Washington, primarily around Grays Harbor and Willapa Bay, in the transition zone between uplands and estuarine intertidal. It occurs along upper tidal river and stream reaches where salinities are low and tidal inundation is infrequent. This densely vegetated association is dominated by the herbaceous species Calamagrostis nutkaensis (grass often >1 m tall), and the much shorter Juncus arcticus ssp. littoralis and the forb Argentina egedii. The non-native Agrostis stolonifera is also typically codominant. Other common species include Angelica lucida, Heracleum maximum, and Sidalcea hendersonii. It is distinguished from other Washington salt marsh associations by the dominance or codominance of Calamagrostis nutkaensis.

Floristics: This densely vegetated association is dominated by the herbaceous species Calamagrostis nutkaensis (grass often >1 m tall), and the much shorter Juncus arcticus ssp. littoralis (= Juncus balticus) and the forb Argentina egedii. The non-native Agrostis stolonifera is also typically codominant. Other common species include Angelica lucida, Heracleum maximum, and Sidalcea hendersonii. It is distinguished from other Washington salt marsh associations by the dominance or codominance of Calamagrostis nutkaensis.

Environmental Description: This is an estuarine high intertidal marsh that occurs along the outer coast in the transition zone between uplands and estuarine intertidal. It occurs along upper tidal river and stream reaches where salinities are low and tidal inundation is infrequent.
Geographic Range: This association occurs only on the outer coastal area of southwest Washington, very nearly a narrow endemic, primarily around Grays Harbor and Willapa Bay.
