Bayberry - beach plum maritime shrubland  (S1)

---

Bayberry - beach plum maritime shrublands are short to moderate height shrub thickets found in the backdune area and in small, protected hollows of the interdune. Sandy soils are a bit more stable than those found in the foredune and exposed areas of the interdune, allowing bayberry, beach plum, and other coastal shrubs to persist. Recreational and developmental pressures continue to be a major threat to the viability of the region’s dune systems and their flora.

Characteristic vegetation: Bayberry (Myrica pensylvanica) and beach plum (Prunus maritima) are the dominant species. Small sundrops / small evening primrose (Oenothera perennis), yarrow (Achillea millefolium), tall wormwood (Artemesia campestris ssp. caudata), poison ivy (Toxicodendron radicans), Virginia rose (Rosa virginiana), and large climbing false buckwheat (Polygonum scandens) may also occur. 
 

In New Hampshire, the only good example of this community is at The Sands (Seabrook).

Bayberry - beach plum maritime shrubland communities sometimes occur as part of larger coastal sand dune systems.
