Name: Pinus contorta var. contorta / Gaultheria shallon - Rhododendron macrophyllum - Vaccinium ovatum Forest Reference: Western Ecology Working Group of... Description: This association occurs on flat to depressional topography with impeded drainage, usually on ancient marine terraces. The predominant Blacklock soil series is nutrient-poor and is underlain by impervious hardpan that inhibits drainage. Seasonal standing water and limited rooting depth stunts tree growth and have caused these stands to be called 'pygmy forest.' Vegetation is mostly stunted Pinus contorta var. contorta with a dense understory of Ledum glandulosum, Vaccinium ovatum, and Rhododendron macrophyllum. Characteristic openings among the shrubs, usually flooded seasonally, have Carex obnupta, Deschampsia caespitosa, Vaccinium uliginosum (= ssp. occidentale), Sanguisorba officinalis, Xerophyllum tenax, Hypericum anagalloides, Sisyrinchium californicum, Calamagrostis nutkaensis, Drosera rotundifolia, reindeer lichens (various species of Cladina and Cladonia), and several species of Sphagnum moss. Some areas where the shallow soil was burned or washed away have a barren pavement of hardpan with virtually nothing growing on it except scattered Pinus contorta var. contorta, with their roots running along the surface of the pavement.  Accession Code: VB.CC.26338.PINUSCONTORTAVA Plot-observations of this Community Concept: 0
