The vegetation map adheres to the 2008 National Vegetation Classification Standard (NVCS) and the Manual of California Vegetation.One-foot natural color imagery flown in May 2005 was used as a base for the delineated polygons and photo interpretation signature in the focus study areas. Additional online digital imagery was deemed necessary as supplementary information and included the National Agricultural Inventory Program (NAIP) imagery flown in the summer of 2005 which was used as a base for areas outside of the focus studies.*Note: It is important to understand that the interpretation in the focus areas is georeferenced to the 1-foot 2005 imagery and will not line up precisely to the NAIP imagery in all cases. Therefore it is not advisable to view the delineations over the NAIP imagery, especially at a fine-scale level in the focus studies.The complete mapping effort is divided into two phases. The first phase is the detailed mapping of several focus study areas which total approximately 4200 acres in size and include the Springtown Preserve and adjacent areas along with Brushy Peak and the upper Altamont Creek drainage. The Phase II portion involves the creation of a more generalized vegetation map for the remaining thirty square miles including much of the remaining Altamont Creek watershed in the northern portion of the Livermore Valley. The University of California Berkeley Herbarium contracted Aerial Information Systems, Inc. in 2008 to create a baseline inventory of wetlands and associated upland vegetation for approximately 38 square miles of land north of the city of Livermore, California, including and adjacent to the Springtown Alkali Sink Preserve. The vegetation map adheres to the 2008 National Vegetation Classification Standard (NVCS) and the Manual of California Vegetation. Rarity Ranking Rarity ranks for various types in this map have been updated utilizing the NatureServe Conservation Status Assessments Rank Calculator Version 3.186, and are current as of July 5, 2022. Rarity ranks are subject to change due to changing threats and trends and as ranking methodologies are further refined.

These standardized names correspond as much as possible to the National Vegetation Classification System (see http://usnvc.org/) or are submitted to the regional editors for induction.Classes for human land use or otherwise unvegetated land were drawn from the California Wildlife Habitat Relationship. https://vegetation.cnps.org/ MCVLevel The standardized level of the vegetation description in the Manual of California Vegetation corresponding with levels of the National Vegetation Classification System http://usnvc.org MapCode The code for a vegetation association, alliance, group, unvegetated type, or land use for polygons that are not natural vegetation. This code matches the Veg field from the Report. Report MapClass The finest level of vegetation type mapped (alliance, association, group or macrogroup); or descriptions for polygons that are not natural vegetation per the mapping classification, including land use and natural barrens or water features. Map classes are described in the mapping report. This name matches the VegName field from the Report.

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 broad distribution with area not subject to threats. Ranks G1-G3 are considered sensitive. See: http://www.natureserve.org/sites/default/files/publications/files/natureserveconservationstatusmethodology_jun12_0.pdf and https://wildlife.ca.gov/Data/VegCAMP/Natural-Communities Ranks are current as of the publication date or update date. http://www.natureserve.org/sites/default/files/publications/files/natureserveconservationstatusmethodology_jun12_0.pdf and https://wildlife.ca.gov/Data/VegCAMP/Natural-Communities 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 critically imperiled/has very few occurrences to S5, when a community is demonstrably secure due to security globally. Ranks S1-S3 are considered sensitive.

Y= yes, sensitive natural community. Alliances and associations with global ranks of G1-G3 state ranks of S1-S3 are considered sensitive natural communities. Additionally if an association has not gone through the ranking process, but is estimated to be sensitive Y will be shown without a G or S rank.
