ECOLOGICAL
LAND CLASSIFICATION
(National Parks
Only)
The
overview map on display shows Mount Revelstoke and Glacier National
Parks classified at the Ecoregion scale. Both Mount Revelstoke
(Illecillewaet River Watershed) and Glacier (Illecillewaet and
Beaver River Watersheds) were classified and described at the
Ecoregion, Ecosection, and Ecosite level (note: this does not
correspond with the provincial method of ecosystem classification.).
The
Ecosite map section on display shows the area surrounding Rogers
Pass, each polygon being classified by Ecosite. An example of an
ecosite designation is:

Each
Ecosite has attributes associated with it, and fits into the larger
Ecosection and Ecoregion levels. Using the Ecosite LR1, within the
Lauretta Ecosection and Interior Cedar-Hemlock Ecoregion, as an
