Summary

The Peninsular Bighorn Sheep Habitat (PBSH) Vegetation Map will help inform scientists in their effort to study fluctuations in the distribution of Peninsular bighorn sheep due to changes in vegetation due to fire, drought and climate change. Thus, the primary goals and objectives of the vegetation map are to develop a spatial geodatabase of vegetation communities deemed essential for Peninsular bighorn sheep habitat and to provide a baseline to monitor natural communities and landscape-scale vegetation change within their range. Quantification of biotic habitat variables will help assess factors that influence Peninsular bighorn sheep and other species population fluctuations. These data are key to conservation of biological diversity in the Plan area, especially given the impacts of increasing periods of drought and effects of climate change. In addition, the completed map is necessary in order to address changes in vegetation makeup due to increased fire frequency and extent throughout the mapping area.

Description

Aerial Information Systems, Inc. (AIS) was contracted by the Coachella Valley Conservation Commission (CVCC) through a Local Assistance Grant originating from the California Department of Fish and Wildlife (CDFW) to map and describe the essential habitats for bighorn sheep monitoring within the San Jacinto-Santa Rosa Mountains Conservation Area. This effort was completed in support of the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP). The completed vegetation map is consistent with the California Department of Fish and Wildlife classification methodology and mapping standards.

The mapping area covers 187,465 acres of existing and potential habitat on the northern slopes of the San Jacinto and Santa Rosa Mountains ranging from near sea level to over 6000 feet in elevation. The map was prepared over a baseline digital image created in 2014 by the US Department of Agriculture Farm Service Agencys National Agricultural Imagery Program (NAIP). Vegetation units were mapped using the National Vegetation Classification System (NVCS) to the Alliance (and in several incidences to the Association) level (See Appendix A for more detail) as described in the second edition of the Manual of California Vegetation Second Edition (Sawyer et al, 2009).

The mapping effort was supported by extensive ground-based field gathering methods using CNPS rapid assessment protocol in the adjacent areas as part of the Desert Renewable Energy Conservation Plan (DRECP) to the north and east; and by the 2012 Riverside County Multiple Species Habitat Conservation Plan vegetation map in the western portion of Riverside County adjacent to the west. These ground-based data have been classified and described for the abovementioned adjacent regions and resultant keys and descriptions for those efforts have been used in part for this project.

Supplemental information
Baseline Imagery for Photo interpretation Since the project commenced approximately 1.5 year after the release of the 2014 NAIP natural color imagery, it was determined to be the most recent reliable image source and would therefore be used as the basis for interpretations. NAIP imagery is widely distributed and provided at no cost to the public. Although photo interpreters had access to higher resolution imagery, it was considered important to reference the data to a source available to all agencies both local and statewide. The 2014 NAIP imagery captures conditions in the mapping area shortly after the onset of the dry season in the month of June. The imagery depicts conditions after four lower than normal rainfall seasons. The imagery is natural color with image resolution (Image Pixel Size) of 1 meter. Although the NAIP 2014 imagery serves as the baseline dataset, other image datasets aided photo interpreters in defining floristic types and delineating vegetation stands. In addition to the NAIP 2014 photo interpreters had access to NAIP 2014 color infrared, NAIP 2012 natural color imagery, and online image sources. Online Imagery In nearly all instances, additional online imagery was needed to help finalize vegetation attribution decisions. On these occasions, online image sets spanning one to as many as five separate years from Google Earth (GE) were used. In addition, the World Imagery layer available through ArcGIS Online was also used where needed. The dates of the online imagery from Environmental Systems Research Institute (Esri) were May 2010. Polygon delineations could be overlain directly onto the online imagery acquired through Esri. However, GE imagery was used with a follow-along tool and viewed on an adjacent screen. The table below shows all image datasets used in the mapping effort. Those denoted with an asterisk are accessed through on-line technology.

ESRI ArcGIS online -Topo Maps -USA Topography Maps Mapping Classification For this mapping effort no classification analyses were conducted. The PBSH Floristic Classification that was used represents a subset of the DRECP vegetation classification completed in 2015 (VegCAMP, 2013, 2016), which was used to derive the preliminary project vegetation descriptions, keys, and other pertinent information. After the initial field reconnaissance trips with CDFW & CVAG ecologists, the preliminary classification was adjusted to include new types encountered in the field. All added types have been verified and accepted by the CDFW. These new alliances and associations were added based on the Manual of California Vegetation Second Edition (Sawyer, Keeler-Wolf & Evens, 2009), and from the adjacent Western Riverside County (Klein & Evens, 2005) and Anza-Borrego State Park (CDFG, 1998) mapping efforts. Mapped types in the PBSH study were characterized for the most part to the alliance level in the NVCS hierarchy and at times to the finer association level where possible. Photo interpreters assigned vegetation stands to more generalized categories in the classification hierarchy (e.g., group or macrogroup) when they were unable to assign vegetation to a specific alliance due to image resolution (most herbaceous types and some wetland types) or in cases of recently burned areas. The mapping classification was updated throughout the production and final phase of the project, with the final mapping classification (see Appendix A) reflecting the finest level that the photo interpreter can identify and map from existing imagery and ancillary data. Field Reconnaissance Field reconnaissance efforts serve two major functions. First, they enable photo interpreters to relate the vegetation ground conditions at each observation site to the signatures on the aerial imagery. Second, with guidance from ecologists in the field, the photo interpreters become familiar with the flora, vegetation assemblages, and local ecology of the study area. At the same time, ecologists gain an understanding from the photo interpreters perspective about assessing vegetation through the framework of map creation. 241 reconnaissance points (both base and distance observations) in seven unique watersheds were taken in January 2016. A second reconnaissance effort was conducted in October 2016 after the initial mapping was completed, and is discussed in more detail in the report. Vegetation Mapping Considerations Minimum Mapping Unit For vegetation mapping, a minimum polygon size is an important consideration when creating and viewing a vegetation geodatabase. A minimum mapping unit (MMU) is established to ensure the map contains polygons of a workable, meaningful size. The choice of a MMU is influenced by the clarity of the imagery, the detail of the mapping classification, the purpose of the data, and time and budget constraints. The MMU can vary for different categories of features being mapped. The Statewide mapping criteria has established different MMUs depending on the area being mapped (e.g., MMUs in Desert areas are different from those in the Sierra Foothills). For this project, there were several established MMUs: 2 acres for upland types, .5 acre for special & wetland features and 5 acres for cover-class and other attribute changes. Further discussion between photo interpreters and CVAG & CDFW ecologists allowed for a 5-10 acre MMU for desert vegetation between extremely closely related types. This was proposed in order to more closely adhere to the adjacent DRECP 10 acre upland MMU rule. At the request of CVAG ecologists, AIS photo interpreters agreed to map wetlands that were distinct from adjacent vegetation to sizes below the project defined .5 acre MMU. CVAG ecologists also requested AIS to map stands of Washingtonia filifera and Prosopis glandulosa to the finest level possible due to the sensitive nature of palm oases and importance of mesquite as a food source for the Peninsular bighorn sheep. The establishment of an MMU requires the need for guidelines when aggregating vegetation that occurs below that defined MMU. In general, similar life forms are aggregated together: tree-dominated types are aggregated with other tree-dominated types, shrub types with other shrub types, and herbaceous types with other herbaceous vegetation types. However, if possible, wetland vegetation types are not aggregated with upland types, even if they are in the same life form. Another guideline is used when a vegetation unit below MMU is aggregated with the vegetation type that surrounds it. This is known as a mapping or vegetation inclusion. Finally, if a vegetation unit that is below MMU is the same life form as two adjacent larger stands, and the adjacent stand types are very dissimilar in environment, the unit may be aggregated with the more environmentally similar adjacent type. In addition to establishing MMU size, guidelines were established for the minimum width (MW) of a map polygon. The rule of thumb was to make the MW roughly half the width of an MMU square. For the .5 acre MMU, the MW is approximately 70 feet and for the 1-acre MMU, the MW is approximately 135 feet. This guideline did not preclude the creation of polygons where a small section fell below the minimum width, as long as the greater portion of the polygon met the stated criteria. This is most common when a narrow stream or riparian polygon was mapped and below MMU or MW portions were included in order to maintain the continuity of the stream or riparian vegetation. As mentioned above regarding overall MMU, AIS opted to map below these limitations where structural, floristic and or ecological characteristics were significantly different from the adjacent vegetation. Another type of MMU mapping consideration pertains to sparsely vegetated or nonvegetated areas. Polygons assigned to a floristic type in the NVCS often contain small areas of unvegetated surface that are too small to delineate. These small areas are generally not separated out as unique features unless they met the minimum mapping resolution. The most common examples of these features include rock outcroppings in shrub dominated communities and small riverine flats or wash channels in riparian stands of vegetation. Association Level Vegetation Mapping Although mapping to the alliance level of detail is this projects standard, photo interpreters mapped the following vegetation types to a finer level of the classification known as the floristic association. These associations are more thoroughly described in Appendix D of this report: Within the Washington filifera (California fan palm oasis) Alliance 14151 Washingtonia filifera Platanus racemosa / Salix spp. Association 14152 Washingtonia filifera / spring (Atriplex Baccharis Pluchea) Association Within the Parkinsonia florida Olneya tesota Alliance 42271 Parkinsonia florida / Hyptis emoryi Association In addition to these three associations, photo interpreters designated in the Notes Field of the database vegetation units that could be potentially mapped to the Pinus monophylla / Cercocarpus ledifolius Association. Accuracy Assessment Due to budgetary constraints, no formal accuracy assessment was performed on the vegetation database. However, given our familiarity with desert and semi-desert vegetation types and our high accuracy assessment scores from the adjacent DRECP area we are confident that the final vegetation data is of good quality and high value.

Field description
Code for the classes of percent birds-eye cover of conifers 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.

Field HdwdCov
* Alias HardwoodCover
* Data type SmallInteger
* Width 2
* Precision 5
* Scale 0
Field description
Code for the classes of percent birds-eye cover of hardwoods 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.
