(swamp horsetail)

(EQUFLU, 20 sites)

IIIB3a. Wet forb herbaceous, fresh herb marsh

Emergent water horsetail in a Seward pond.

Vegetation- Equisetum fluviatile (swamp horsetail) is well represented to

abundant and dominates this type. Although occurrence is sporadic,

Potentilla palustris (marsh fivefinger) and Menyanthes trifoliata (buckbean)

are the most common associates. Species richness is low.

Physical setting- Swamp horsetail is an emergent species that grows on

sites with permanent to semi-permanent standing water (lakes and ponds).

The type is common on the Copper River Delta and the Portage, Placer, and

Twentymile river valley wetlands. It occurs on flood plains, estuaries,

beaches, and raised tidal flats. Sites sampled are on flat surfaces at

elevations to 100 feet.
