** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** THE PRIMARY GOAL OF THIS PROJECT IS TO PROVIDE FOREST LANDOWNERS TOOLS AND KNOWLEDGE FOR ASSESSING CARBON ADDITIONALITY AND FOR MODELING MIXED-SPECIES EASTERN U.S. FORESTS. SHORT-TERM GOALS INCLUDE EXPANDING EYIELD TO MIXED-SPECIES FORESTS, MODELING CARBON ADDITIONALITY, TRAINING STUDENTS, FACILITATING STAKEHOLDER ENGAGEMENT, ASSESSING USE OF TECHNOLOGY, AND ENHANCING AN ONLINE EDUCATIONAL SYSTEM (OLAF). LONG-TERM GOALS INCLUDE ENHANCING THE QUALITY OF AND ASSISTING IN EFFICIENT MANAGEMENT OF U.S. FORESTS, SUSTAINING ECONOMIC VIABILITY OF SMALL PRIVATE FORESTS, AND ENHANCING LANDOWNER QUALITY OF LIFE. OBJECTIVES ARE TO: (1) DEVELOP CONTEMPORARY QUANTITATIVE METHODS FOR MODELING GROWTH OF MIXED-SPECIES FORESTS, AND INCORPORATE THESE INTO THE EYIELD MODEL; (2) INCORPORATE ESTABLISHED METHODOLOGY FOR QUANTIFICATION OF CARBON ADDITIONALITY INTO EYIELD; AND (3) ASSESS END-USER SATISFACTION WITH THE ENHANCED EYIELD MODEL, DEVELOP TUTORIALS AND VIDEOS THAT ILLUSTRATE ITS USEFULNESS, AND DEVELOP OUTREACH CONTENT TO COMPLEMENT EYIELD AND ENHANCE OLAF OFFERINGS. AS AN INTEGRATED PROJECT, THE RESEARCH COMPONENT ADDRESSES KNOWLEDGE GAPS CRITICAL TO MIXED SPECIES GROWTH AND YIELD AND MANAGEMENT PRACTICES. THE EXTENSION COMPONENT ADDRESSES MODELING CARBON ADDITIONALITY, USER SATISFACTION WITH THE EYIELD MODEL, AND ONLINEEDUCATIONAL OPPORTUNITIES.
