Abstract

Experimental Project 904.02 (EP904.02) was established in 1987 to examine the performance of western larch (Larix occidentalis), Siberian larch (Larix sibirica), and ponderosa pine (Pinus ponderosa) at ICHwk2, SBSmw, ESSFwk1, and SBPSxc sites in the Cariboo Region. Survival and growth of these non-native species over a 22-year period were compared with that of lodgepole pine (Pinus contorta var. latifolia), Douglas-fir (Pseudotsuga menziesii), and hybrid spruce (Picea engelmannii glauca), which are common forest components in this region. Subsequent to the installation of this experiment, climate change-related forest health issues became an important management concern, and the extension of species beyond their natural range was considered as a mitigation strategy. Western larch was a good candidate for assisted migration, and interim guidelines are now in place that allow this species to be planted in many Cariboo Region ecosystems. As a result of these recent changes, our 22-year western larch results are especially relevant to current forest management.
