This brochure describes the coastal sand dune ecosystems considered to be biologically ?at risk? in the province - the ecosystems? components, history, present status, and importance - and explains why they are at risk.
Occupying areas of open sand bounded
by the ocean and the forest, these sparsely vegetated ecosystems struggle for existence. Both the front
and rear boundaries of sand dune
ecosystems are determined by the sea: no vegetation can grow within reach of the salty waves, and tree growth is only possible away from the burning salt spray. ccupying areas of open sand bounded by the ocean and the forest, these sparsely vegetated ecosystems struggle for existence. The harsh dune environment changes from front to back, creating a variety of unique habitats. On the exposed, high-energy west coast of
British Columbia, sand movement is
high and the dunes are extensive, with
distinct vegetation in each zone.
