  1. Vegetation and Fuels MappingAn Interagency ApproachA Briefing to the Fire plan Steering committeeJune 4, 2009 The California Department of Forestry and Fire Protection Mark Rosenberg: California Department of Forestry and Fire Protection

  2. Vegetation and Fuels Mapping Outline • Standard interagency products • Current Status • Work In Progress

  3. Vegetation and Fuels Mapping Powerful Monitoring Tool • Map Hazardous Fuels • Track Forest Health Trends • Assess cumulative impacts • Model Wildlife Habitat • Estimate Timber, Biomass and Carbon Stocks • Examine the effectiveness of existing policies • across jurisdictions • Design Fuels Reduction Strategies • Provides opportunities for agencies to look • across jurisdictions and programs

  4. Vegetation Derived Fuels and the Fire Plan Input Data Fire Plan Use Level of Service FUELS LAYER Fuel Rank

  5. Cooperative Strategy Vegetation and Fuels Mapping 5 Panel Project Areas Statewide 5-year Cycle YR 1 - Imagery Acquisition YR 2 - Change Detection YR 3 – Vegetation Updates YR 4 – Inventory YR 5 - Trend Analysis • Baseline Vegetation Map • Inventory Link • Change Monitoring • Vegetation Map updates • Trend analysis

  6. Cooperative Mapping Approach • Make use of existing vegetation data • Cost effective • Avoids redundancy • Promotes ownership and acceptance of data and analysis • Encourages collaboration • Define a consistent spatial base (polygons) • Independent of map attributes • Stand based • Objective delineation of landscape features • Hierarchically add thematic detail necessary to meet map standards • Specific focus on detailed type and structure attributes • Accuracy assessment • Forest inventories used as independent reference data and as a statistical sample for forest attributes

  7. Vegetation Product Description • Vegetation Type in 2 classification schemes • CALVEG (FGDC Alliance Level) • Wildlife Habitat Relationships • Crown Closure in 10% class breaks • Size (seedling, sapling, pole, small, medium, large, Multi-storied) • Primary and Secondary Attributes in Tree types http://www.fs.fed.us/r5/rsl/projects/frdb/layers/ev_mid.html

  8. Fuels Product Description • Surface Fuels (40 categories) • Ladder Fuels • Crown Fuels (CBD From FIA)

  9. Current Status • Vegetation Data: • 1997-2005 • 1: 100,000 scale & 1:24,000 scale • Fuels Data: Last Fire Plan update in 2004

  10. Current Efforts • Integrate Existing Vegetation Map Products from Other Sources • Leverage existing data and programs (FIA, RSL, FRAP,NLCD) • Link Vegetation maps to Inventory and derive canopy attributes (Forest Vegetation only)

  11. Central Coast Update Map Updates In Progress North Coast Update Integrates Existing Data From Other Sources • North Coast – 2007 • NWFP products • Central Coast – 2001 • NLCD products • Tree Size mapping (2001 Imagery) • Central Valley – 2001 • NLCD products • Tree size mapping Central Valley Update

  12. Collaborative Work in Progress • Task 1: Central Coast Polygon Mapping and Tree Structure Database 2001 (2.3 million acres) • Task 2: Southern Sierra Tree Structure Database 2001 (7.75 million acres) • Task 3: South Coast Polygon Mapping and Tree Structure Database 2001 (200,000 acres) • Task 4: Central Valley Tree Structure Database 2001 (18.5 million acres): • Task 5: North Coast Database Updates 2007 (6.8 million acres) • Task 6: Forest Inventory Database Links 2001-2007 • Task 7: Canopy Fuels Derivation from Inventory:
