Name: Tsuga heterophylla - Picea sitchensis - Sequoia sempervirens Rainforest Macrogroup
Reference: NatureServe Biotics 2019
Description: This macrogroup covers coastal and inland rainforests at low elevations dominated by <i>Abies amabilis, Acer macrophyllum, Alnus rubra, Arbutus menziesii, Callitropsis nootkatensis, Picea sitchensis, Pinus contorta var. contorta, Pseudotsuga menziesii, Sequoia sempervirens, Thuja plicata</i>, and/or <i>Tsuga heterophylla</i>. Additional trees that may be present include <i>Abies grandis, Pinus monticola</i>, and <i>Chamaecyparis lawsoniana</i>. This macrogroup combines predominantly evergreen rainforests of the region and the coastal redwood forests of northern California. These forests and woodlands occur in the hypermaritime (within salt spray exposure), the submaritime, as well as more protected areas of the leeward Coast and west-side Cascade ranges. They may also occur on cool temperate lower montane slopes where winter snowpack typically lasts for several months, sometimes referred to as the "rain-on-snow" zone because of the common occurrence of major winter rainfall on an established snowpack. Climate is wet, mild maritime. Forests along the immediate coast experience a uniformly wet and mild climate, where precipitation ranges from 100 to 300 cm/year with frequent fog and low clouds during warmer months, and additional moisture from fog drip can be significant. Away from the coast, climate is still mild but with less moisture (as low as 50 cm/year) and greater temperature extremes.
