  1. LANDSCAPE LEVEL BIODIVERSITY

  2. Relevant FREP questions • Are ecosystems represented across the landscape in time and space? • Is there a sufficient degree of connectivity among ecosystems? • Are stand-level management objectives for maintaining biological diversity (e.g., retention of wildlife trees and coarse woody debris) adequately contributing to the maintenance of diverse ecosystems over the landscape?

  3. Milestones • Initial scoping papers completed (L.Kremsater) (May-July 2006) • Working group established (Sept 2006) • Review, revision and prioritization of “DART” tool and indicators (Dec 2006) • Project Charter developed (draft) (Jan 2007)

  4. Draft Project Objectives TWO Inter-related projects • To provide quantitative data on a range of indicators which are generally accepted as important elements of “patterns of natural disturbance”. • To provide landscape-level context to stand-level biodiversity RSM data through pilot effectiveness evaluations. How……Proposed Pilots which will • Critically assess the pilot approach, and apply this knowledge to developing standardized procedures for future effectiveness evaluations.

  5. Goal #1: Evaluating biodiversity attributes using current DART indicators

  6. Goal #2: Putting FREP stand-level data into a landscape context • directed by the goals of stand-level retention and what is being monitored at the stand-level • need to know the distribution of important stand level elements across the landscape (i.e., snags, big trees, and large CWD) • Need to develop predictive “attribute trajectories” for different stand ages and forest types for these elements • Data from: literature values, cruise data, stand-level FREP data • Compare predicted “natural” abundance of these structures to actual FREP field data – how well are we doing?

  7. Next steps • Update DART code to meet current software standards • Modify DART logic model to incorporate new/revised indicators and FREP objectives • Develop trajectories for each of the stand level elements • Pilot implementation in Prince George TSA and Sunshine Coast TSA
