Variable density spacing was carried out within the RRZ?s of a number of streams scattered over six major drainages within Block #2 of TFL 39 of Cascadia?s North Island Timberlands, in order to speed up riparian old growth/large stem development, and enhance riparian diversity and habitat. This would be achieved by manipulating density and tree species diversity (both vertical and horizontal), creating improved riparian habitat for a variety of species, wind-firm the trees, create larger future stem diameters, predispose stems for larger future coarse woody debris, provide for increased future in-stream complexity, increase or maintain shrub and herb layers for wildlife forage, overland flow filtering and nesting habitat. Red alder was to be treated, in order to release under-story conifers. Red cedar, as well as food and medicinal shrubs and herbs were fostered to improve 1st. Nations forest values. Wildlife trees were created and/or predisposed for cavity nesters and stressed by screefing for increased sapsucker use. Reinhard Muller.
