Display Field: OAK_FLAGS

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: <div style="text-align:Left;"><div style="font-size:12pt;">In Northern California, many areas of oak woodland are converting to Douglas-fir forests. This conversion stems from fire exclusion and other changes in land use and land management. This metric uses relative conifer cover and proximity to conifer stands data from the 2018 Fine Scale Vegetation Map to create two classes, actively converting to conifer forest or threatened with conversion to conifer forest.Metric Classes <ul><li>Actively Converting to Douglas-fir (or any other conifer species except Sargent cypress): Oak stands with greater than or equal to 10% relative conifer cover. </li><li>Threatened with Conversion to Douglas-fir (or any other conifer species except Sargent cypress): Open Canopy Oak Woodland stands within 0.25 miles of any 2018 Fine Scale Vegetation Map polygon stand (excluding Sargent cypress) with a relative conifer cover of greater than or equal to 25%. </li></ul>See Chapter 6 of the <a href="https://www.onetam.org/sites/default/files/pdfs/marin_regional_forest_health_strategy_2023.pdf" style="color:rgb(0, 97, 155); text-decoration-line:none; font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif;">Marin Regional Forest Health Strategy</a> (Page 263 - Open Canopy Oak Woodland Stands Threatened or Converting to Conifer Forests) for more information. </div></div>
