Fragment:
"This report describes British Columbia standards for ecosystem mapping at scales of 1:5000 to 1:50 000. ... These mapping standards use a three-level classification hierarchy of ecological units, including ecoregion units and biogeoclimatic units at broader levels, and site units and vegetation developmental stages (combined as ecosystem units) at a more detailed scale. Ecoregion classification is hierarchical, with five levels of generalization; the lowest level, ecosection, is used here. Biogeoclimatic classification includes four levels, including zone, subzone, variant, and phase. Ecoregion and biogeoclimatic units are broad-level delineations derived from provincial maps. Within these broader units, site-level polygons describe ecosystem units composed of site series, site modifiers, and structural stages. ..."--Abstract.
