The edges of streams and rivers (riparian zone) provide important fish and wildlife habitat.
Different sections are often varied, due to different soil types, degree of slope, and exposure. This variety creates mini-climates and encourages biodiversity.
Riparian vegetation supports many bird, animal and insect species.
Some require specific plants to survive, others need a specific habitat type or size.
Scientific studies show the very minimum riparian zone, on each side of a stream or waterbody, required for different animals.
For example, 15 to 30 metres for fish, 60 metres for songbirds.
But urban streams have been invaded.
Trails follow along the edges of stream banks and buildings sit close.
The result is a loss of vegetation, habitat, animal species, groundwater reserves, and an increase in erosion and pollutants.
To help correct the problems, revegetation projects have been undertaken since the late 1990's, combined with protective fencing and slope stabilzation to maximize recovery.
