Name: Vaccinium cespitosum / Sanguisorba officinalis Fen
Reference: NatureServe Biotics 2019
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. <i>Vaccinium cespitosum</i> 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 <i>Carex obnupta</i> and sheets of the tiny black liverwort <i>Cephaloziella</i>. <i>Vaccinium cespitosum</i> covers 30-70% of the stands, and <i>Sanguisorba officinalis</i> may cover up to 85% of the herb layer. Stunted <i>Spiraea douglasii</i> and <i>Camassia quamash</i> suggest that the soil has very low nutrient status. <i>Thuja plicata, Rhododendron</i> spp., and <i>Gaultheria shallon</i> 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. <i>Sphagnum</i> and <i>Aulacomnium palustre</i> occur among the <i>Vaccinium</i> hummocks and may cover 50-95% of the moss layer. <i>Anemone oregana var. felix</i> is present in these stands.
