South East
Coastal Lowland (Coastal Douglas-fir Zone)
Lying in the
dry rainshadow of the Vancouver Island Mountains, the Douglas-fir
ecosystem stretches from the southern tip of the Island, up the
east coast as far as about Campbell River. Here, the Douglas-fir
is a climax species, for there is insufficient moisture in most
areas to support the cedars and hemlock that would normally replace
them. Along the edges, and in openings created when larger trees
have fallen, Broadleaf Maple (Acer macrophyllum) occurs, and Pacific
Dogwood (Cornus nuttallii), British Columbia's floral emblem, brightens
the forest greens. On drier sites, Arbutus (Arbutus menziesii) reaches
for the sun.
On the forest
floor, Trilliums (Trillium ovatum) can provide an early spring carpet
of white. Delicate Calypso orchids (Calypso bulbosa) are dependent
on a mycorrhizal relationship with the big Douglas-firs, and the
saprophytic Indian Pipe (Monotropa uniflora) draws its nourishment
from the roots of other plants, since it has no chlorophyll of its
own.
Red-flowering
Currant (Ribes sanguineum) and Salmonberry (Rubus spectabilis) compete
for the early-spring attentions of the Rufous Hummingbird (Selasphorus
rufus), and provide food for Black Bears (Ursus americanus) in late
summer.
Overhead, Townsend's
Warblers (Dendroica townsendii) and Pacific-slope Flycatchers (Empidonax
difficilis) give their thin calls, to lay claim to a piece of the
forest canopy. Western Screech-owls (Otus kennecottii) call at night,
their whistled notes winding down like a bouncing ball.
It is a habitat
rich in diversity, and it is readily accessible to visitors in the
many parks and trails in the region.
