Name: Vaccinium caespitosum / Sanguisorba officinalis Dwarf-shrubland
Reference: Western Ecology Working Group of...
Description: This association occurs on acidic mineral soil around the margins of seasonally wet meadows in the northern Coast Range of Oregon. Trees and tall shrubs are absent. Vaccinium caespitosum forms a network of low thickets and hummocks 0.3-0.5 m in height around openings with seasonally flooded shallow pools with a very sparse cover of Carex obnupta and sheets of the tiny black liverwort Cephaloziella. Vaccinium caespitosum covers 30-70% of the stands, and Sanguisorba officinalis may cover up to 85% of the herb layer. Stunted Spiraea douglasii and Camassia quamash suggest that the soil has very low nutrient status. Thuja plicata, Rhododendron spp., and Gaultheria shallon occur on logs and other elevated microsites and can eventually shade out the association if hydrology is altered or a sufficient area of elevated substrate develops. Sphagnum and Aulacomnium palustre occur among the Vaccinium hummocks and may cover 50-95% of the moss layer. Anemone oregana var. felix is present in these stands.
