Trees are over 200 years in age and growing very slowly. The understory is sparse with small amounts of Gaultheria shallon or Ledum groenlandicum present. Sphagnum spp. are present. This association is distinguished by the closed canopy of Tsuga heterophylla, the sparse understory with Sphagnum spp., and sphagnum peat soil.
