Description:
The stand- and forest-level growth and yield impacts of different stand management prescriptions (e.g., planting density, post-thinning density, fertilization) for forests in the interior of British Columbia are currently facilitated by growth prediction models and decision tools that have been developed or calibrated for use in the B.C. interior. However, the fact that available growth models are based on incomplete knowledge of the growth, yield, and value impacts of harvesting and stand management decisions, is often not fully recognized. The available long-term database for growth and yield research in interior forests is limited and fragmented, and much of the data have been obtained from sources outside of British Columbia. Further refinements and improvements in growth models and decision tools for interior forests will depend, to a large extent, on the availability of local, high quality, long-term growth and yield data. With funding provided by the Forest and Range Development Agreements (FRDA I and II) and Forest Renewal B.C. (FRBC), the B.C. Ministry of Forests Forest Science Program undertook large investments in long-term stand management field experiments during the 1980ís and 1990ís. This extensive network of area-based research installations is designed to document the effects of various stand management treatments (partial cutting, thinning, fertilization) and regimes (planting and post-thinning density, fertilizer regimes), on stand growth and development across a range of species, biogeoclimatic zones, and stand conditions throughout the B.C. interior. The scheduled re-measurement of these interior stand management research installations (EPís) is providing valuable treatment response estimates and growth and yield calibration/validation data for growth and yield models and estimation tools such as TASS and TIPSY. Outputs from these models are used to support timber supply analysis, silvicultural prescriptions, and investment decisions. The portfolio of active, long-term interior stand management experiments currently totals 77 individual field installations.
