This study examined four biotic zones that made up the territory of the park, determined by their vegetational type.

In the northern Canadian Rockies, black spruce also occurs in this biotic zone.

A list of biotic zones, and corresponding elevations, is presented below:

This biotic zone is notable for containing Giant Sequoia.

The ecology can be described by biotic zones, which are marked by either a tree indicator species, or by a lack of trees.

The subalpine zone is the biotic zone immediately below tree line around the world.

In the sloping ravines that transition between the two biotic zones, red oak find a foothold.

Hogup Mountain consists of three gross biotic zones determined by soil, altitude, and moisture.

The altitudes listed for the biotic zones are for the central Sierra Nevada.

Instead, ecologists divide the Rocky Mountain into a number of biotic zones.
