Why Woody Biomass? Forests, Fire, Climate Change and Power
Background Sources of Forest Biomass include logging slash, lumber mill wastes, small non-merchantable logs and shrubs • Reduced wildfire impacts to public health and safety (Public Resources Code, CA Fire Plan) • Renewable Energy from Biomass Resources (RPS - SB107, 2006 and SB1078, 2002, Bioenergy Action Plan) • Carbon sequestration - for mitigating global climate changes (AB32, 2006; AB1504, 2010) Policy Issues Public Benefits • Improve air quality (fewer fire emissions) • Reduce net carbon emissions • Create fire safe communities • Promote healthy, resilient forests • Produce lumber, energy and other products
Threats to Forests, Communities, and Carbon • Wildfire • Insect • Water • Disease • Climate change
Wildfire Threat to Ecosystems Health • Key Findings: • Increased acres burned, greater fire severity, and modification of historic fire regimes impact vegetation communities that are adapted to, or even dependent on natural wildfire. • 18.5 million HPL Acres, 64% Federal • The most at risk ecosystems are Klamath and Sierra Mixed Conifer and Douglas-fir in the Klamath/North Coast, Modoc and Sierra bioregions; Shrub types: Sagebrush and Coastal Scrub.
FOUNTAIN FIRE 1992 64,000 Acres
Forest Ecosystems Most Impacted by Insect and Disease Outbreaks • Key Findings • Forest Pests cause widespread commercial, aesthetic, economic and environmental impacts throughout California’s ecosystems. • Ecosystems currently suffering the most extensive damage are Sierran Mixed Conifer, Eastside Pine, Red Fir and White Fir. • Those at greatest risk from future damage include White Fir, Red Fir and Lodgepole Pine.
Challenges • Strategically link fire threat reduction and other public benefits to biomass utilization strategies • Reduce economic barriers to speed forest biomass utilization • Creating market based incentives for small landowner forest management/fuel treatment • Addressing Sustainability
Strategically linking fire threat reduction and other public benefits to biomass utilization strategies

FRAP Biomass Sustainability Model • Address State and Federal policy goals (AB 32, AB 1504, State RPS, Federal RFS etc.) • Update biomass maps and estimates of potential for California (MW, MBF, BDT) • Model current and future forests, and wood/energy products • Model Scale and Intensity of harvest at different price points paid for Biomass material • Evaluate CA Forest Practice Rules and USFS management plans ability address carbon and ecosystem sustainability issues
Policy Integration challenges • Balancing ratepayer benefits and environmental benefits • Relatively high cost of forest biomass distributed energy generation and sensitivity to feedstock prices • Interconnection costs • Environmental and permitting costs • Air quality and environmental justice concerns • Funding • Sustainability
Approach • Develop baseline biomass estimates (total standing live tree) in GIS • Estimate annual biomass potential • by land owner type • including growth projections • Model biomass availability under • Forest practice rules (FPA) • USFS land management plans • Sustainability goals • Tree size available to biomass market based on price • Evaluate impacts on sustainability of forest resources and ecosystem services • Create an interactive model on the web to evaluate facility locations, resource supply and ecosystem impacts
