CSU Geographic Information Center at Chico (GIC), with assistance from the Vegetation Classification and Mapping Program at CDFW (VegCAMP) created a fine-scale vegetation and land use map of portions of the Modoc Plateau in California. This map covers approximately 1,945,674 acres in eastern Lassen and southern Modoc Counties. It was produced using a base of true-color 2016 one-meter National Agricultural Imagery Program (NAIP) imagery. Polygons were assessed for vegetation types, percent covers, clearing disturbance, invasive plant cover and other attributes. Average accuracy was 84 percent.

NVCSName
The standardized name of the vegetation description used in the 2008 National Vegetation Classification System (see http://usnvc.org/) . Since the NVCS does not have categories for human land use or otherwise unvegetated land, those descriptions were drawn from the California Wildlife Habitat Relationship.

NVCSLevel

GlobalRank
The state rarity ranking of the plant community mapped (ranks are available for all California alliances, and some associations). Ranks are based on a set of criteria including the rarity of the community (extent and occupancy), the threats that the community is subject to, and any known trends in the quality, size, or quantity of stands within the state. Ranks go from G1 which is critically imperiled/has very few occurrences to G5, when a community is demonstrably secure due to security globally. Ranks G1-G3 are considered rare. See: http://www.natureserve.org/sites/default/files/publications/files/natureserveconservationstatusmethodology_jun12_0.pdf

StateRank
The state rarity ranking of the plant community mapped (ranks are available for all California alliances, and some associations). Ranks are based on a set of criteria including the rarity of the community (extent and occupancy), the threats that the community is subject to, and any known trends in the quality, size, or quantity of stands within the state. Ranks go from S1 which is most imperiled/has very few occurrences to S5, when a community is demonstrably secure due to security statewide. Ranks S1-S3 are considered rare.

Rare
Rarity of the vegetation type. Alliances and associations with state ranks of S1-S3 are considered rare.
