The effects of riparian harvesting on fish habitat and ecology of small headwater streams: 2003/2004 year end reports
Maloney, David A.
Large woody debris recruitment in the research sites were marked-to-leave to ensure the minimum retention requirements were met. The residual trees (>15cm diameter) were selected by species, size and location in relation to the stream. Preferred species to leave were deciduous species, western hemlock, subalpine fir, lodgepole pine, and lastly white spruce. The selection process also included consideration of their location including: trees leaning toward the stream, trees in clumps that would require all or no removal, and trees with root systems integral to the streambank. In all stands there were lots of choices for retention. In the lodgepole pine (Pl) leading stands in the SBSdw2 where mountain pine beetle was a high risk, no lodgepole pine had to be retained as there were enough other tree species available in the riparian zone for marking. During harvesting, the operators were instructed that they could exchange a marked tree for an unmarked tree of similar criteria if that would minimize damage to the riparian area and provide ease in harvesting.
