Aquired from GeoBC, this spatial view contains summarized attributes and ecosystem polygons for Sensitive Ecosystems Inventory (SEI) projects. SEI mapping systematically identifies, classifies, maps and evaluates rare and fragile ecosystems in a given area. Ecosystems mapped may include (but are not limited to) older forests, woodlands, coastal bluffs, herbaceous and sparsely vegetated ecosystems, grasslands, riparian ecosystems and wetlands. Seasonally flooded agricultural fields and older forests may be included because of the wildlife habitat values they provide. SEI polygon attributes include Ecosection, BGC unit, Sensitive ecosystem class and subclass, ecosystem mapcode, structural stage, ecosystem condition and viability. SEI information is derived from aerial photography, supported by selective field checking of the data. The data in this spatial view includes products using varying methodologies. SEI may be based on original air photo interpretation for SEI polygons, or as an SEI theme derived from Terrestrial Ecosystem Mapping (TEM) polygons. |
