During this effort, CNPS completed vegetation sampling across the southern portion of the Ciervo-Panoche Natural Area (CPNA), including 21 relevé plots and 52 rapid assessment surveys, that represent 28 vegetation alliances. Building upon previous vegetation sampling and mapping efforts, we also compiled and quality-controlled greater than1,800 surveys of vegetation data from BLM to develop a robust regional vegetation classification of the inner Central Coast. All new and compiled classification data are stored within a geodatabase and a standardized Access database.CNPS additionally produced a fine-scale vegetation map and monitoring data for the Hubbard Hill, Anderson Canyon, and Freeborn Mt allotments in San Luis Obispo County in conjunction with the US Bureau of Land Management and The Nature Conservancy. This vegetation map encompasses 7,000 acres and is based upon 2020 NAIP imagery. It includes 15 map unit codes for natural vegetation. All areas of natural vegetation were mapped at the floristic association/alliance level. The vegetation classification follows Survey of California Vegetation (SCV) standards. The classification is based on about 1,900 regional vegetation surveys along the inner Central Coast from Ciervo-Panoche Natural Area to Carrizo Plain National Monument, using classification techniques such as clustering. The map was produced applying heads-up digitizing techniques, using a base of 2020 NAIP imagery. Map polygons were assessed for Vegetation Type, Percent Cover, Exotics, etc. The minimum mapping unit (MMU) is 1 acre. The average producers’ map accuracy across all types was 77 percent and the average users’ map accuracy was 73 percent , these scores fall below the state standard of overall accuracy at 80 percent. Upon scoring the accuracy assessments, CNPS staff have reviewed all polygons where the field verification name and map unit did not agree, to correct issues in photo interpretation and attribution for the final map. A total of 720 map polygons representing 15 vegetation map classes were developed.For detailed information, please refer to the following report:J. Buck-Diaz, K. Sikes, S. Vu, A.

The purpose of the project is to to create an accurate baseline vegetation map of Hubbard Hill, Anderson Canyon, and Freeborn Mt BLM allotments in San Luis Obispo County. This map will provide planners with detailed information to help identify high quality habitat and rare communities. Although the primary purpose of the map is to document vegetation communities, it also provides structural data such as herbaceous, shrub and tree cover, and information about the level of disturbance within the vegetation stand. 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. Please check CDFW’s Natural Communities page for the most up-to-date rarity ranks (https://www.wildlife.ca.gov/Data/VegCAMP/Natural-Communities). References: J. Buck-Diaz, K. Sikes, S. Vu, A.

ConifCover Percent bird’s-eye cover of hardwood trees estimated in 1% increments within a vegetation stand. Percent cover, also referred to as “density,” is a quantitative estimate of the aerial extent of the living plants for each vegetation layer within a stand. Cover is the primary metric used to quantify the importance or abundance of a life form and/or species. It is important to note that the photointerpreters could only accurately quantify the vegetation that is visible on the aerial imagery. Therefore, “bird’s eye” total cover was mapped, meaning that the cover of understory layers which were obscured by overstory layers was not included. For this reason, total cover for shrubs and herbaceous plants may be underestimated if their extent was hidden under the crowns of trees and may differ from assessments done on the ground by field crews. 999 = not evaluated. This occurs where the map unit is not vegetation or the overstory cover > 40% HdwdCover Percent bird’s-eye cover of hardwood trees estimated in 1% increments within a vegetation stand.

HerbCover Percent cover, also referred to as “density,” is a quantitative estimate of the aerial extent of the living plants for each vegetation strata within a stand. Cover is the primary metric used to quantify the importance or abundance of a life form and/or species. Vegetative cover for a given polygon is assigned for woody vegetation (conifer, hardwood, shrubs) as a whole integer. Herbaceous vegetation is attributed to the following range categories:   1 = None or Not Observable, <2% 2 = >2-10% 3 = >10-40% 4 = >40% 999 = Not Applicable/Not Assessed. This occurs where the map unit is not vegetation or the overstory cover > 40% J. Buck-Diaz, K. Sikes, S. Vu, A. LaFever-Jackson & J.M. Evens. 2023. ExoticCover Photointerpreters assigned each existing polygon a code reflecting the level of impact by exotic invasive species such as Bromus diandrus grass. Polygons were not created or split because of differences in the presence of exotics. Table 4, adapted from 2013 California Desert Vegetation Map and Accuracy Assessment in Support of the Desert Renewable Energy Conservation Plan (VegCAMP 2013) presents the map classes for Exotics. J. Buck-Diaz, K. Sikes, S. Vu, A. LaFever-Jackson & J.M. Evens. 2023. Roadedness Level of impact by paved and unpaved roads. Impact is defined by the proportion of polygon vegetation that is roadless. 0 - None Visible, 1 - Low: at least 2/3(67% to 100%) of the vegetation polygon area is roadless, 2 - Moderate: between 1/3 and 2/3 (33% to 66%) of the vegetation polygon is intersected by roads of any kind, 3 - High: less than 1/3 (<33%) of the vegetation polygon lacks roads of any kind. J. Buck-Diaz, K. Sikes, S. Vu, A. LaFever-Jackson & J.M. Evens. 2023. Clearing Lists the level of clearing within each polygon. None Visible - No ghost lines of tilling, differential effects of enclosure/exclosure fencing, effects of grazing/browsing, etc. are visible. Low: Less than 1/3 of a vegetation polygon has visible evidence of clearing, prior agricultural activity or other effects. Moderate - A vegetation polygon has more than 1/3 but less than 2/3 visible effects of clearing, prior agricultural or other effects. High - A vegetation polygon has more than 2/3 visible effects of clearing, prior agricultural or other effects. J. Buck-Diaz, K. Sikes, S. Vu, A. LaFever-Jackson & J.M. Evens. 2023.

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. Ranks are current as of the publication date or update date. https://www.wildlife.ca.gov/Data/VegCAMP/Natural-Communities/Background CaCode California Natural Community Codes - unique code assigned to alliances and associations. https://www.wildlife.ca.gov/Data/VegCAMP/Natural-Communities MCVAlliance The standardized name for the alliance within the NVCS as interpreted in the Manual of California Vegetation. https://vegetation.cnps.org/ SensitiveFlag The Sensitive Flag is a field where exceptions to what is in the ranking for an alliance or a determination for a group based on alliances are captured. For example, an alliance might be ranked as G4/S4, because it is broadly distributed in the state and covers a considerable area. However, every association within that alliance is considered sensitive because it isn't broadly distributed or is locally threatened. Such an alliance would have Sensitive = Y because everywhere the alliance is represented the association community is sensitive. States for this field include: "AllAssocOfAlliance" (described above); "AllAllianceOfGroup" (similar to AllAssocOfAlliance but used when all the alliances in the group are ranked as sensitive); "AllAssocOfMapClass" (used when the map only contains a subset of associations known in the state and all of these are sensitive); "SecondryFromSplit" (this can occur when the alliance or other community/level which was mapped was subsequently split into multiple, both sides of the split are known to be present in the map, the primary is not sensitive but the less common community/level from the split is sensitive); and "AllAssocFromRegion" (when it is known that only a subset of associations from alliance exist within the ecoregion that the map is in and all these are sensitive). https://vegetation.cnps.org/ SensitiveFlagNotes MCVGroup The standardized name for the group within the National Vegetation Classification System, with some potential exceptions within the Manual of California Vegetation Database. https://vegetation.cnps.org/ MCVMacrogroup The standardized name for the macrogroup within the National Vegetation Classification System, with some potential exceptions within the Manual of California Vegetation Database. https://vegetation.cnps.org/ CommunityLink The link to the alliance in the Manual of California Vegetation Online. https://vegetation.cnps.org/ Acres GIS Calculated acres based on calculation done in California (Teale) Albers, NAD83 SecondCaCode The secondary California Code of the Alliance or Association, typically when original community was split and both communities could exist in map https://www.wildlife.ca.gov/Data/VegCAMP/Natural-Communities SHAPE_Length Length of feature in internal units.
