Name: A.1648
Reference: EcoArt 2002
Description: These communities are found on shallow deflation plains and topographic depressions of coastal dunes along the northwestern Pacific Coast of Oregon. Annual precipitation is high, falling almost entirely as rain. Temperatures are cool in summer, with abundant fog. These communities occur on the driest of the backdune deflation plain habitats, usually at the highest microelevations. Soils are seasonally moist, stabilized sands with little organic material and are generally nutrient-poor. Sand movement is typically minor, but deposition becomes more important towards the seaward margin. This alliance typically has an open ground layer of ~Lupinus littoralis$, with ~Poa macrantha$ locally codominant. Other herbaceous associates include ~Polygonum paronychia, Calystegia soldanella, Agoseris apargioides, Glehnia littoralis ssp. leiocarpa$, and ~Lathyrus littoralis$. Other herbaceous species in the deflation swales where this alliance occurs are ~Carex obnupta, Juncus falcatus$, and ~Argentina egedii ssp. egedii (= Potentilla pacifica)$ in microhabitats with a somewhat longer hydroperiod. Shrub and tree seedlings occasionally colonize moister interior stands, especially ~Gaultheria shallon$ and ~Pinus contorta$.
