Carbon Sink

Forests absorb carbon dioxide from the air through photosynthesis and the carbon is stored in trees and other components of the ecosystem. Forests also produce carbon dioxide through respiration, decay or when they burn. A forest is a carbon sink if it absorbs more carbon than it produces. Conversely, if a forest produces more carbon than it absorbs it is a carbon source.

Chronosequence study

A chronosequence study in forest sciences is a study that takes place on a set of forested sites that share similar attributes (e.g., climate and topography) but are of different ages

Cryptogams

Cryptogams are plants that have no true flowers or seeds and reproduce by spores. They include mosses, liverworts, and lichens. Ferns are considered advanced cryptogams because they reproduce by spores but are differentiated into roots, stems and leaves.

CWHvm

CWHvm is the abbreviation for the very wet maritime Coastal Western Hemlock biogeoclimatic subzone. The province of British Columbia is divided into 16 zones, including the Coastal Western Hemlock (CWH). A zone is a large geographic area with a relatively uniform regional climate. The CWH zone is subdivided into climatically distinct subzones, including the vm, or very wet maritime subzone. The CWHvm has a wet, humid, mild, oceanic climate and has an extensive distribution on the BC coast including western Vancouver Island.
