Anatomy of a Creek

The estuary is the semi-enclosed coastal body of water where the creek meets the ocean.
The headwaters are the small streams that are the source of the river.
Restoring the Lyall Creek Habitat

Over enormous amounts of time, species of plants and animals living in the same area evolve very complex systems. These are called habitats.
Lyall Creek provides habitat for a vast number of species.
The Salmon Species of Lyall Creek
Lyall Creek supports populations of Coho (Oncorhynchus kisutch), Chum (Oncorhynchus keta) and sea-run Cutthroat Trout (Oncorhynchus clarki).

It is the only protected salmon-bearing watershed in the Southern Gulf Islands.
The Riparian Habitat of Lyall Creek

Riparian areas are the zones between the land and the water.
They filter out pollutants from land runoff and prevent erosion. They also supply shelter and food for many aquatic animals.
Baseline Inventory and Monitoring

Various surveys have been conducted in recent years to gain a better understanding and knowledge of the flora and fauna that are supported by the creek.
