Description:
The Sicamous Creek project is located about 15 km SE of the town of Sicamous. The site is part of the Hunters Range of the Shuswap Highlands and is classified as ESSF wc4. The project began in 1992 and was logged in the winter of 1994-95. The broad objective of the Sicamous Creek project is to provide the forestry community with information on the sustainable management of wet, cold, high-elevation forests in the Southern Interior. We are meeting this goal by measuring the response of valued ecosystem components to widely differing types of logging (patterns of canopy removal) and soil disturbance (site preparation for regeneration). From this information, operational foresters should be able to choose from alternative methods of harvesting and regenerating this forest, based on the specific sets of forest values they are required to manage. The project is based on a large-scale replicated experimental design, with 5 operational harvest treatments covering a range of openings sizes: 10-ha clearcuts, arrays of 1-ha openings, arrays of 0.1-ha patch cuts, individual tree selection and uncut controls. The design allows study of the effects of overall harvest treatments, opening size, width of leave strips and edge effects. A secondary nested set of experimental treatments examines site preparation for regeneration: operational mounding, scalping, burning and undisturbed controls. The first 10-year phase of the project conducted pre-harvest studies, implemented the study design, conducted initial post-harvest assessments, and began data analysis, publication and the extension program. The initial study plan called for measurements to be made over a 30 year period. Over 40 researchers and students from nine research institutions and private practice have initiated and in many cases completed studies on the site. Their topics have included: forest history and stand dynamics; harvest logistics and costs; planted and natural regeneration; tree pests, diseases, snow damage and windthrow; soil chemistry and biology; microclimate and hydrology; diversity of plants, animals, lichens and fungi; and the interaction of these components. Project scientists have produced a total of 37 journal papers so far and more are in the pipeline. The bibliography lists includes over 200 items, including abstracts from a wide range of extension presentations to operational foresters.
