COMMON LIMITING FACTORS in WRIA 22-23 and their impact to physical processes and salmon


Physical Process Effects

Poor riparian conditions are typically the result from intentional removal of vegetation.  This is usually associated with land use conversion or active timber harvest management. Lack of riparian cover contributes to increased water temperatures.  Increased water temperature decreases the amount of dissolved oxygen the water can hold. An insufficient riparian corridor does not adequately filter surface water runoff which can allow sediment and pollutants to enter the stream/river.   An inadequate riparian corridor, such as hardwood dominant or void of vegetation, does not provide adequate long term wood recruitment.
