Sustainable forest management (SFM) has stimulated a growing interest in the identification and conservation of biological diversity and ecological processes. Snags are a valuable component of stand-level structure and therefore good surrogate indicators of biodiversity. Numerous species of vertebrates are known to depend critically on snags and wildlife trees; management of this resource is vital to proper land stewardship and ecosystem integrity. The consideration of long-term stand structure goals that maximize the biological values of individual trees and groups of trees left after harvest is critical. A strategy that incorporates multiple approaches to stand-level retention is recommended. THE LONG TERM GOAL IS TO EFFECTIVELY MANAGE TO RECRUIT AND MAINTAIN SNAGS USING CURRENT AVAILABLE SCIENTIFIC AND OPERATIONAL KNOWLEDGE TO PRESERVE HABITAT DIVERSITY FOR THE PG TSA. THIS DOCUMENT SYNTHESIZES EXISTING INFORMATION ABOUT STANDING DEAD WOOD (APPENDIX 1 AND 2) AND PROVIDES GUIDANCE FOR IDENTIFICATION AND MAINTENANCE OF SUITABLE STANDING DEAD WOOD (TABLES 1 AND 2). Critical knowledge gaps have been identified. These issues are referenced in Table 1 according to the strategy they satisfy. Before any projects are under taken however, it is recommended that: · a TSA-wide data base is developed to house all information collected, and a protocol for updating Table 1 is established and, · a dialogue coordinated by the PG TSA SFM working group is established between licensees, provincial and federal research agencies, consultants, and universities so that duplication of work is avoided and better use of resources is achieved. Table 1 outlines tactical responses to the identified knowledge gaps. The tactics are based on personal interviews, current information - contained in Appendix 1 (discrete literature review and consultations) and the annotated bibliography (Appendix 2), other documents, and the authors' opinions. This table is intended to be updated annually providing a method to track research trials, indicate present and future opportunities, and prioritize projects. [Patience Byman]
