Name: Xerophyllum tenax - Sanguisorba officinalis Meadow
Reference: NatureServe Biotics 2019
Description: This association occurs on acidic mineral soil around the margins of seasonally wet meadows in the northern Coast Ranges of Oregon. The association is characterized by hummocks of <i>Xerophyllum tenax</i> interspersed with pockets of <i>Sanguisorba officinalis</i>, throughout which are distributed tightly packed mats and hummocks of <i>Sphagnum capillifolium</i> and <i>Sphagnum mendocinum</i>. The hummocks of <i>Sphagnum capillifolium</i> are in part elevated above groundwater influence, lowering the nutrient status of this association. <i>Vaccinium cespitosum, Pteridium aquilinum</i>, and <i>Carex obnupta</i> are occasional to frequent associates. The juxtaposition of the typically upland <i>Xerophyllum</i> with typically wetland <i>Sanguisorba</i> and <i>Sphagnum</i> suggests that this association occurs in a long-term hydrologic tension zone between upland and wetland. Long-term variation in water levels can be caused by beavers, humans, climatic variability, or combinations of these variables.
