Name: Hudsonia tomentosa - Paronychia argyrocoma Dwarf-shrubland
Reference: Eastern Ecology Working Group of...
Description: This riverwash sand or gravel barren community, characterized by Hudsonia tomentosa var. intermedia, occurs along a limited extent of the Saco River on the border of New Hampshire and Maine. It is unusual in that the major process structuring this vegetation is irregular alluvial flooding as opposed the to wind-driven sand deposition that drives nearly all other known vegetation dominated by Hudsonia tomentosa. The Saco River originates in the White Mountains and flows through thick sand and gravel, which is deposited on point bars during early spring floods. The sand deposits are often extensive, resulting in some secondary eolian dune formation. As a result, the community is highly unusual in its species composition, supporting species of coastal sands such as Lechea maritima and Polygonella articulata, species typical of the cooler climates of the White Mountains, such as Solidago simplex var. randii and Paronychia argyrocoma, and species characteristic of grasslands such as Andropogon gerardii, Schizachyrium scoparium, Danthonia spicata, Solidago nemoralis, and species of Panicum.
