Summary

The Central Valley Riparian Mapping developed by the Geographic Information Center (GIC) is used as a planning tool for the Department of Water Resources (DWR) and stakeholders in planning regional flood management projects and plans associated with the Central Valley Flood Protection Plan (CVFPP). These data are used to assess current areas of vegetation and habitat within the flood protection system, set measurable objectives within CVFPP Conservation Planning areas for the enhancement of specific types of habitat, and create initial assessments of potential impacts of proposed multi-benefit projects associated with the State Plan of Flood Control. This dataset was developed as part of the California Department of Water Resource's Central Valley Flood Protection Program to facilitate regional planning and conservation and enhancement of biological resources by the Department of Water Resources, project partners, and regional stakeholders.

Description

The Feather River was mapped using 2018 National Agricalutural Inventory Program (NAIP) imagery, and using a classification developed by the California Native Plant Society (CNPS) based in the National Vegetation Classification System (NVCS). A report describing mapping methodology for a similar project can be found here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=184992.For more information about California's classification, see https://vegetation.cnps.org/.Changes in a remap effort can occur due to several factors, some due to physical change and some due to non-physical change. Examples of factors that represent physical change are: stand maturation or decadence, fire, erosion, deposition, anthropogenic disturbances such as scraping/clearing, urban development, agricultural development, and restoration. Non-physical changes include: improvement in imagery quality, incorrect original mapping, imagery shifts, improvement of older linework, and change in level mapped (classification). Imagery quality continues to improve with time, which allows the photointerpreter to better determine which species are present and in what amounts to determine its best classification. A photointerpreter could also disagree with the previous mappers decisions and may change the classification in the remapping effort. A more subtle map change, which does not affect the acreages significantly, is when the photointerpreter improves old linework to make it better fit the classification type visually. Also, when the NAIP imagery is ortho-rectified, in some years it does not perfectly align with the year it is being compared to and linework needs to be shifted/redrawn. Lastly, a photointerpreter may have remapped an Alliance at the Group level due to lack of confidence at the Alliance level, and vice versa the interpreter may have mapped an Alliance that was previously mapped at Group level due to better confidence at that level. All of these factors should be taken into consideration when using and comparing these data to previous efforts.

Cover-rule exceptions were made for shrubs that never get very dense. These shrub types such as Heterotheca oregona can go down to 3% cover and still be called a shrub Alliance. Common environments for these exceptions were gravel bars and alkali flats.

SensitiveFlag 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 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 senstive); "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)
