Coburg Peninsula hosts one of the few shorelines in the Victoria area with coastal sand dunes
. Beach grasses help to stabilize the dunes and provide habitat for insects, small mammals and birds. Much of the native dunegrass
) habitat on Coburg Peninsula has been trampled by people and out-competed by invasive species
such as Scotch broom. However, fragments of this important and fragile habitat still remain on the spit and local volunteers are working to restore and maintain existing habitat.
At the entrance to the lagoon, the receding tide exposes sand and gravel flats. Many types of birds gather to feed here on small animals that burrow in the sand, such as worms, amphipods and shellfish. Smaller sand and mud flats
are located along the western shore.
The entire lagoon is essentially an estuary
, as it receives freshwater from streams and salt water through the tidal channel. A salt marsh
is located at the mouth of Colwood Creek, Bee Creek and in a fringe along the western shore of the lagoon. Estuaries and salt marshes are highly productive ecosystems, and provide rich feeding grounds for birds as well as a sheltered environment for fish. Esquimalt Lagoon supports large eelgrass meadows, a rich shallow water habitat where many species of birds, fish and invertebrates find food and refuge.
