Name:
Pinus contorta var. contorta / Ledum groenlandicum / Sphagnum spp. Wooded Bog & Poor Fen Group
Reference:
NatureServe Biotics 2019
Description:
This wetland forested group occurs from southern coastal Alaska (Kenai Fjords), coastal British Columbia south into coastal Washington and Oregon, and west of the coastal mountain summits (not interior). It can be dominated by any one or a number of conifer species (<i>Callitropsis nootkatensis, Picea sitchensis, Pinus contorta var. contorta, Tsuga heterophylla</i>, and/or <i>Tsuga mertensiana</i>) that are capable of growing on saturated or seasonally flooded soils. Overstory is often less than 50% cover, but shrub understory can have high cover. Common shrubs include <i>Elliottia pyroliflora, Gaultheria shallon</i> (southern portion of the Alaska distribution only), and <i>Vaccinium ovalifolium</i>. Common understory species include <i>Carex anthoxanthea, Carex pluriflora, Carex stylosa, Eriophorum</i> spp., <i>Lysichiton americanus, Nephrophyllidium crista-galli, Phegopteris connectilis, Thelypteris quelpaertensis, Trichophorum cespitosum</i>, and <i>Sphagnum</i> spp. Treed bogs and fens are common in southeastern Alaska, less so farther south. Forest bogs and fens can be mostly small-patch in size, but can be extensive in the Pacific Northwest. This group is found on poorly drained soils, ranging from organic veneers over wet mineral soils to deeper organics peaty soils; the peat is mostly deep, mossy peat, but can include woody peat. The peat may also be shallow over rock. The water source is stagnant or slowly moving acidic groundwater or direct precipitation.
