MANAGING FOREST ECOSYSTEMS FOR MULTIPLE ECOSYSTEM SERVICES IS EXCEEDINGLY DIFFICULT AND LAND-MANAGERS CURRENTLY DO NOT HAVE THE PROPER TOOLS AT THEIR DISPOSAL TO OPTIMIZE THESE GOALS. THEREFORE IT IS A CENTRAL AIM OF THE ECO-OPT (ECOSYSTEM SERVICE OPTIMIZATION) PROJECT TO CO-DEVELOP TOOLS AND/OR MODULES WITH FOREST MANAGERS THAT CAN BE ADDED TO THEIR CURRENT TOOLBOX TO ENSURE FOREST HEALTH IN THE CONTEXT OF MULTIPLE DEMANDS ON FOREST ECOSYSTEMS. STAKEHOLDERS, INCLUDING TRIBAL FOREST MANAGERS AND TRIBAL MEMBERS, PRIVATE FOREST OWNERS AND MANAGERS, CONSULTING FORESTERS, PUBLIC AGENCY STAFF, AND BIOENERGY SECTOR CONSUMERS OF WOODY FEEDSTOCKS WILL ALL BE ENGAGED FROM THE BEGINNING TO THE END OF THE ECO-OPT PROJECT. OUR OVERALL GOAL IS TO CONDUCT FOUNDATIONAL RESEARCH ON THE IMPACTS OF EXTRACTING BIOMASS ENERGY FEEDSTOCKS FROM DEGRADED AND DISTURBED FORESTS ON OTHER ECOSYSTEM SERVICES AND TO CO-DEVELOP DECISION-MAKING TOOLS WITH LAND MANAGERS FOR OPTIMIZING BIOMASS EXTRACTION WITHOUT COMPROMISING ECOSYSTEM SERVICES. THE PROJECT WILL USE EXISTING INVENTORY DATA AND NEW FIELD SOIL DATA TO MODEL THE BIOENERGY POTENTIAL OF FEEDSTOCKS DERIVED FROM DEGRADED AND DISTURBED FORESTS, WHILE ENHANCING OTHER ECOSYSTEM SERVICES. WE WILL FOCUS ON TWO CONTRASTING FOREST ECOREGIONS- DEGRADED NORTHEASTERN FORESTS, AND DISTURBED NORTHERN ROCKIES FORESTS
