Tsuga mertensiana - Abies amabilis - Callitropsis nootkatensis Tree Island Alliance | NatureServe Biotics 2019

Name: Tsuga mertensiana - Abies amabilis - Callitropsis nootkatensis Tree Island Alliance Reference: NatureServe Biotics 2019 Description: This is a forested alliance with dominants of <i>Abies lasiocarpa, Tsuga mertensiana, Abies amabilis</i>, and/or <i>Callitropsis nootkatensis</i>. The structure of this alliance is limited to tree islands, which are stands of full-height trees surrounded by meadows. These tree islands occur near treeline where extremely deep snowpacks discourage tree growth in topographic depressions, and the forest interdigitates with herbaceous communities. The entire landscape of meadow with dotted tree islands is often referred to as "parkland." This alliance contains only the forested part of that landscape. Tree islands are typically individually quite small, consisting of 5-10 trees or more, and do not form a continuous canopy typical of forests or woodlands. These tree islands are not krummholz, but are full-statured trees. This alliance occurs in the Washington and Oregon Cascades, on the Olympic Peninsula and Coastal Mountains of British Columbia.  Accession Code: urn:lsid:vegbank.org:commConcept:38941-{829BD6AA-A038-4EB6-8D64-FEF30195FB93} Plot-observations of this Community Concept: 0
