Description: CSU Chico's Geographical Information Center (GIC), with assistance from CDFW's Vegetation Classification and Mapping Program (VegCAMP) created a fine-scale vegetation and land use map of portions of the Modoc Plateau in California. The map follows the National Vegetation Mapping Classification standards as well A Manual of California Vegetation and covers the eco-region subsections Devil’s Garden and Adin Mountains. This map covers approximately 855,998 acres in Lassen and Modoc Counties. It was produced using a base of true-color 2018 one-meter National Agricultural Imagery Program (NAIP) imagery. Polygons were assessed for vegetation types, percent covers, clearing disturbance, invasive plant cover and other attributes. The minimum mapping unit for standard vegetation polygons, agriculture and urban areas and water are 1 acre, while for wetland and riparian areas, the MMU is 0.25 acres. Overall fuzzy map accuracy was 81.6%, but individual vegetation types varied in their accuracy. Please see the mapping report and the contingency tables for details to determine confidence in individual types. For detailed information please refer to the following reports: Boul, R., T. Keeler-Wolf, J. Ratchford, T. Haynes, D. Hickson, R. Yacoub, B. Harbert, J. Evens. 2021. Classification of the Vegetation of Modoc and Lassen Counties, California.
