Summary

Under contract to the California Department of Fish and Wildlife (CDFW), Aerial Information Systems (AIS) created a fine-scale vegetation map of portions of the Southern Sierra Nevada Foothills in central California. The mapping study area, consists of approximately 1,824,939 acres, of Mariposa, Madera, Tulare, Kern, and Los Angeles counties. The minimum mapping unit (MMU) is 2 acres; exceptions are made for wetlands and riparian types, which were mapped to a 1-acre MMU. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS).

Description

Under contract to the California Department of Fish and Wildlife (CDFW), Aerial Information Systems (AIS) created a fine-scale vegetation map of portions of the Southern Sierra Nevada Foothills in central California. AIS subcontracted the California Native Plant Society (CNPS) to conduct field reconnaissance assistance for this project, as well as accuracy assessment (AA) field data collection; and Soar Environmental Consulting to assist in the AA field data collection. CDFWs Vegetation Classification and Mapping Program (VegCAMP) provided in-kind service to allocate and score the AA.

The mapping study area, consists of approximately 1,824,939 acres, of Mariposa, Madera, Tulare, Kern, and Los Angeles counties. Work was performed on the project between 2019 and 2022. The primary purpose of the project was to further CDFWs goal of developing fine-scale digital vegetation maps as part of the California Biodiversity Initiative Roadmap of 2018.

CNPS under separate contract and in collaboration with CDFW VegCAMP developed the floristic vegetation classification used for the project. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS).

The vegetation map was produced applying heads-up digitizing techniques using a 2018 base of one-meter National Agricultural Imagery Program (NAIP) imagery (true-color and color infrared), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 2 acres; exceptions are made for wetlands and riparian types, which were mapped to a 1-acre MMU.

Field reconnaissance and accuracy assessment enhanced map quality. There was a total of 111 mapping classes. The overall Fuzzy Accuracy Assessment rating for the final vegetation map , at the Alliance and Group levels, is 89.5 percent .

Field description
AIS was contracted to map to the Alliance level. However, at the time of mapping there were several vegetation types for which the final vetting had not been completed. By the end of the project these types were determined to be associations rather than alliances and assigned to their corresponding place in the vegetation hierarchy. The result was that 9 of the types became Associations. So rather than lump up to the Alliance level it was decided to keep them as Associations and not lose that detail. The final map contains 111 types that were mapped, composed of 75 Alliances and Alliance-level types such as Provisional Alliances, Semi-natural Alliances, and Mapping Units; 9 Associations, and 15 Miscellaneous Classes relating to features such as agriculture, water, and urban disturbance; and 12 upper-level hierarchical types, such as Class, Subclass, Macrogroup and Group. When the photo interpreter could not confidently classify a polygon at the alliance level, the polygon was assigned a broader upper-level code. This was most common with herbaceous communities, whose differences at the alliance level are often not readily discernible on imagery. Each map unit is described in Appendix B; the map classification is presented in Appendix A; and summary tables of polygon counts and acreage by VegCode are presented in Appendix C.

Field description
Percent birds-eye cover of hatrdwood trees estimated in 1% incremetns 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%

Conifer Dieback is a True/False modifier attribute to indicate the mere presence of tree conifer death within a polygon. The amount of death is not assessed. Using the base imagery, the photo interpreter simply assessed the polygon for any standing dead conifer trees (even only one tree in a polygon). The modifier is an indication of natural death and not death caused as a result of fire. Hardwood and shrub death were not assessed.

Field description
Roadedness Disturbance is defined as the level of impact in a polygon by paved and unpaved roads, off highway vehicle (OHV) trails, railroads, berms, and covered aqueducts. Impact is defined by the proportion of any polygon that is contiguously without these features, as shown in Table 5. The table is adapted from VegCAMP (2013). Roads following polygon boundaries were included in the assessment. Each existing vegetation polygon was assigned a Roadedness Disturbance class. Polygons were not created or split because of differences in roadedness.

* Data type SmallInteger
* Width 2

Field description
This indicates the level of impact on vegetation through tillage, scraping, mining, etc. Disturbance from structures, pavement, or debris is not included here but is addressed in Development Disturbance. Anthropogenically Altered Disturbance captures past disturbances in the landscape that are still visible through their impact on vegetation, but do not have enough of an impact to change the vegetation type or percent cover range. For example, striations from former cultivation may be present on parcels of land that have not been under agriculture for decades. Anthropogenically Altered Disturbance is typically bounded by a straight-line feature such as a fenceline or road, implying man-induced activity. Not included are small clearings caused by OHV traffic at road intersections, fire effects, and powerline tower pedestal clearings. Polygons were not created or split because of differences in anthropogenically altered disturbance, but existing vegetation polygons were assigned one of the classes presented in Table 7, which was adapted from VegCAMP (2013).

Alias Development Disturbance
* Data type SmallInteger
* Width 2
* Precision 5
* Scale 0
Field description
Development Disturbance accounts for the level of impact by structures and settlements that are smaller than the MMU criteria for land use. Structures may include buildings, tanks, trailers, metal electrical towers, communication towers, and utility and mining structures. This attribute includes paved parking lots and collapsed structures. Note that it also includes debris such as junked vehicles, major trash dumping, etc., the removal of which could result in a vegetation stand that could be in very good to pristine ecological condition. Disturbance that does not involve these types of features is accounted for in Anthropogenically Altered Disturbance. Polygons were not created or split because of differences in Development Disturbance, but existing vegetation polygons were assigned a Development Disturbance class. Table 6, adapted from VegCAMP (2013), presents the map classes for Development Disturbance.

Field description
This attribute was used to indicate how the VegCode coding decision was reached for a polygon by identifying what type of field data (if any) was used to support the vegetation type assignment. For polygons that did not have any corresponding point data, the value of photo interpretation was assigned. The Method ID attribute facilitated the AA sample allocation process, as polygons that had reliable field information for type assignment could be identified and omitted from the final allocation. The following is a list of the values used: 1 = Rapid Assessment (current project) 2 = Relev (current project) 3 = Field Verification (current project) 4 = Photo Interpretation 5 = Adjacent Stand Information or Ground Photo 6 = AIS Reconnaissance (current project) 7 = Other Information 8 = Older Plot Data/Other Agency Recent Plot Data) 9 = Older Recon Data &/or Other Agency Recon Data 10 = Accuracy Assessment (current project) 60 = Additional Recon Information/Inconsequential Project Field Info

Field description
Land use is the human use of the land and is embodied through such features as urban centers, towns, mining, agriculture, and individual settlements. As mentioned in Section 2.6.3.1.2, in this mapping effort land use was represented both as a possible vegetation class and as a separate attribute of a vegetated polygon. Every attempt was made to correlate the coding within both layers. A land use polygon was mapped if it was at least 1 acre in size. The hierarchical format of the land use classification is such that more-detailed classes may be added at lower levels of the hierarchy for future more detailed land use mapping efforts. For example, the Urban (1000) class could be subdivided further into Residential (1100), Commercial (1200), Industrial (1300), Transportation/Communication (1400), and so on. The land use code assignment was mostly at an Anderson Level I (Anderson et al., 1972) with lower levels for specific categories, as shown below: 0000 = Not assigned/Not assessed 1000 = Urban 1400 = Utility (Canal and aqueduct facilities) 2000 = Agriculture (includes nurseries) 9502 = Plantation 9800 = Undifferentiated Water (contains water at time of imagery) In this work effort, the definition of the 1400 land use code correlates to the VegCode code of Major Canals and Aqueducts (9804).
