Knowledge Benchmarking and Meta-Analysis for ACE 130-007

Description: Simply defined, the Allowable Cut Effect (ACE) transfers anticipated timber yields from the future to the present, resulting in a calculated increase in the current annual allowable cut. In essence, it lets a company realize an immediate increase in fibre supply based on the amount of wood it will be possible to harvest later on. The implementation of Intensive Forest Management practices plays an important role with respect to the application or use of the ACE, by attempting to achieve sustainable increased yields. For example, by shortening rotation over the long term using some form or combination of Intensive Forest Management practices (improved growing stock, commercial thinning, fertilization, etc.), present-day annual allowable cut can be increased by applying the ACE, since it can be expected that more, faster growing trees will be available for harvest in the years to come.

Knowledge of how forests respond to Intensive Forest Managment initiatives in terms of specific effects on annual allowable cut has not been completely documented of fully understood from a large-scale, overview perspective, or put into succinct and comprehensive terms for forest managers and planners. Intensive Forest Management is expected to play an important role on the FRP's primary goal of bringing about a sustainable increase in wood fibre harvest of 10% over 10years, across Tembec license areas in Ontario. An important first step for the FRP in providing sound-science, and ultimately a suite of well developed options for the implementation of Intensive Forest Management programs for forest practitioners has been to support the Knowledge Benchmarking Project in the gathering and synthesis of existing knowledge, expertise and research pertaining to Intensive Forest Management practices and ACE.

This project has resulted in the development, production and distribution of a comprehensive document that details and ranks various Intensive FOrest Management treatments by tree species in relation to the ACE criteria.
