To determine the response to spacing of older western larch trees. This trial was established in 1958 in a fire-origin, 31-year-old, mixed stand of western larch, Douglas-fir and lodgepole pine, on an IDFdm2 site northwest of Cranbrook in the Cranbrook Forest District. In this single-tree experiment, 120 larch trees were selected, with 20 trees in each of six diameter classes. Four crop-tree thinning treatments (clearance of all competing vegetation to radii of 2.4, 3.6 and 4.8 m around each tree, and no clearing) were randomly assigned to five trees in each diameter class. The trees have been remeasured on roughly a five-year schedule for the life of the trial. ...

The Long Term Soil Productivity (LTSP) study in BC was initiated in 1991 to determine how soil compaction and organic matter removal affect soil processes and site productivity. In BC, three fully replicated LTSP installations now exist and a fourth complete set of replicates is currently being installed. There are three replicate blocks in the Sub-boreal Spruce (SBS) biogeoclimatic zone with one replicate each near Topley, Prince George, and Williams Lake. The site in the Boreal White and Black Spruce (BWBS) biogeoclimatic zone is in the Dawson Creek Forest District. The fully installed Interior Douglas-fir (IDF) site is near Kamloops and the IDF site currently being installed on calcareous soil is in the Invermere Forest District. In the Interior Cedar Hemlock (ICH), two sites are being installed to compare to a site in northern Idaho that is part of the big American LTSP project. ...
