Summary

With funding from the Bureau of Land Management (BLM), the California Native Plant Society (CNPS) Vegetation Program has collected and compiled vegetation data, produced a vegetation classification, and produced a fine-scale vegetation map of select BLM land units in the inner Central Coast of California. 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.

Description

With funding from the Bureau of Land Management (BLM), the California Native Plant Society (CNPS) Vegetation Program has collected and compiled vegetation data, produced a vegetation classification, and produced a fine-scale vegetation map of select BLM land units in the inner Central Coast of California. During this effort, CNPS completed vegetation sampling across the southern portion of the Ciervo-Panoche Natural Area (CPNA), including 21 relev 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.

Field description
Percent birds-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, birds 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%

Field description
Is the vegetation type 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.

Field description
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).
