This map is one in a series of vegetation maps produced by the University of California, Riverside Center for Conservation Biology (UCR CCB) for the Coachella Valley Multiple Species Habitat Conservation Plan. UCR CCB created a fine‐scale vegetation map of the Dos Palmas Conservation Area (Reserve Management Unit 4 under the Plan) that covers approximately 25,800 acres in the Coachella Valley of Riverside County, California. This map and report were prepared for the Coachella Valley Multiple Species Habitat Conservation Plan (MSHCP) under contract with the Coachella Valley Conservation Commission (CVCC). The primary purpose was to develop a dynamic and accurate vegetation map for the Dos Palmas Conservation Area, so that it may be applied to future conservation efforts, and assist with management of the 27 species and 27 natural communities listed within the Plan. This unit is the third major part of the ongoing initiative to map vegetation in all conservation units within the Plan area. The Dos Palmas Conservation Area final vegetation map and report were completed in 2016. Fieldwork, photo-interpretation and mapping were performed from 2015-2016. One hundred nintety-one reconnaissance vegetation assessment plots were conducted within the study area, in addition to one hundred thirty-two rapid observations of vegetation at pre-determined points. Photo-interpretation of 2013 imagery and field information were combined to produce delineations of vegetation alliances and associations according to the California Department of Fish and Wildlife classification system, outlined in the Manual of California Vegetation Second Edition (Sawyer et al. 2009). Thus, the current version of the map best represents the status of vegetation in 2013. In 2017-2019, UCR CCB was tasked with correcting the 2014 map, for attributes and geography, and creating a 2018 map update. The same imagery and plot information was used, but attributes and geometry were corrected, addittional attributes for cover and disturbance were added to the original map. The vegetation type feature now comprise 1257 polygons. The Rapid Assessment point feature class was also corrected for errors. The mapping boundary was not altered. The 2018 map used 2018 aerial imagery as a basis for delineation and attribution. 20180101 20190930 Vegetation map was produced using aerial imagery captured in 2018, with additional information from plot data in 2017-2018. Thus, this map is a reflection of the vegetation present in the year 2018.

Esri Sequential unique whole numbers that are automatically generated. AnthroAlteration This indicates the level of impact on vegetation through tillage, scraping, grazing, 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. Menke, J., E. Reyes, A. Glass, D. Johnson and J. Reyes. 2013 California Vegetation Map in Support of the Desert Renewable Energy Conservation Plan. California Dept. of Fish and Wildlife, California Energy Commission; 4/2013. Available from: http://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=62826 Development 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. Menke, J., E. Reyes, A. Glass, D.

Polygons were not created or split because of differences in the presence of exotics, but existing vegetation polygons wer eassigned an Exotics class. Menke, J., E. Reyes, A. Glass, D. Johnson and J.

Cover is the primary metric used to quantify the importance or abundance of a life form and/or species. Menke, J., E. Reyes, A. Glass, D. Johnson and J.

Available from: http://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=62826 Roadedness The Roadedness Disturbance code reflects the combination of the amount of roads in the polygon and the roads’ effect on the contiguous space that has no roads – that is, where the roads fall within the polygon. This definition of roadedness has the advantage of helping to identify roadless areas, but the disadvantage of being scale independent. For example, any polygon with a road more or less bisecting it will be assigned a code of Moderate, regardless of size. However, a very large polygon with a “Moderate” Roadedness Disturbance code might still contain an extensive roadless area Menke, J., E. Reyes, A. Glass, D. Johnson and J.

Available from: http://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=62826 AlterHydrologic This attribute denotes where a wash or sheet flow has been diverted from its natural path by restricted sheet flow or active channel flow crossing under a road, railroad, berm, etc., resulting in a vegetation difference downslope. The effect must create a boundary‐forming break in vegetation type, shrub cover, tree cover, or herbaceous cover along the impediment. The modifier is only attributed to the polygon downslope of the impediment. The upslope portion on the polygon boundary must at least in part follow the hydrologic impediment. Drainage ditches conveying flow off the side of a road (though often visible on imagery) are not considered unless they make a boundary‐forming break in the vegetation. Menke, J., E. Reyes, A.
