Updates of OSAF Old-growth Position Statement and Position Booklet Completed

Under SAF policy guidelines, unit position statements have a 5-year lifespan and OSAF’s “Managing Mature and Old-growth Forests” recently was the focus of a review and revision to remain current. In December the OSAF Executive Committee approved the updated position, which is now available at

Old-growth forests remain an especially important and timely issue for state and federal forestlands where interest in diameter-, age-, and location-based harvest restrictions persists. OSAF continues to advocate for active management by forestry professionals to achieve diverse benefits from older forests versus arbitrary and inflexible directives that prohibit the effective application of local professional expertise and experience. Some newer issues and concepts that the updated position incorporates include the need for active management to address the effects of climate change on older forests, and the use of percentage targets for various successional stages of forests (versus fixed locations) that better mimic natural landscape patterns and changes.

OSAF now has nine active position statements on important forestry issues, and members are encouraged to review these statements and use them to articulate a professional perspective when discussing forest resource issues with people outside the profession. The nine current positions, along with background information about SAF and OSAF, have been compiled in an updated PDF that has been formatted for printing as a booklet or for electronic sharing. It is available at the URL listed above. Contact: Paul Adams, OSAF Policy chair,
