DESCRIPTION
Known for its timber production, the upper Mashel Basin has been subject to logging and other timber-related activities for many years. Not only have legacy effects of past logging practices limited the age of existing stands, but they have greatly decreased the input of large wood into the Mashel Basin. The hardening of banks and introduction of logging roads have led to unstable slopes, increased erosion, and introduced more fine and large sediments into the system. To reduce these effects, watershed partners have taken to installing a number of engineered logjams on the Mashel River. These large structures, paired with riparian plantings of native trees and shrubs, have not only added more wood to the system, but have improved channel stability and complexity and decreased the amount fine sediment moving through the system. Though the ELJs have added habitat complexity to basin, it has been noticed that these structures are not accruing natural wood as hoped. Until protection of upstream habitat can be guaranteed and forests are given the opportunity to mature, there will be a constant need to introduce wood into the system. To address this, the Salmon Recovery Program endeavors to have a minimum of 75 functioning logjams within the Lower Mashel Reach at any given time.
