City of San Diego, Planning, MSCP 20030601 vector digital data ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/100_199/ds188.zip http://bios.dfg.ca.gov/ In 2002, the City of San Diego (City) received funding through a U. S. Fish and Wildlife Service (USFWS) Section 6 Planning Grant to complete an inventory and management plan of vernal pools within the City’s jurisdiction. This inventory (performed during 2003) builds on several previous studies and surveys, which were used to determine the general locations of individual vernal pools and complexes. However, much of the area currently owned by the City and other jurisdictions has never been surveyed for specific vernal pools and, in many cases, historical maps do not accurately represent the existing basins. This inventory focuses on these areas. This inventory does not, however, include vernal pools known to occur on military lands (i.e., MCAS Miramar, Navy Chollas Heights) within the City but not under City jurisdiction. A comprehensive vernal pool plant survey has been completed for each complex within the City. City staff estimated percent cover for the six vernal pool species listed as endangered or threatened by the state and/or federal government, or considered covered (i.e. adequately conserved) by the Multiple Species Conservation Program (MSCP). This project utilized advanced geospatial technology to update information on the location of individual vernal pools and complexes, including documentation of changes in vernal pool distribution due to development and restoration efforts subsequent to Bauder's report (1986). This inventory expands and updates existing information, and provides the basis for a gap analysis of vernal pool conservation efforts within the City of San Diego. The updated inventory provides current and expanded information regarding the location of vernal pool basins and rare, threatened, and endangered biota within the City of San Diego. The resulting data, which includes vernal pools on private and public lands, will be analyzed to determine the extent of vernal pool protection, as well as current preservation and management needs. This new information will serve as the basis for updating the City of San Diego Vernal Pool Management Plan (1996), which identifies and prioritizes management activities for vernal pools on land owned by the City of San Diego. DATA ASSUMPTIONS AND LIMITATIONS: Vernal pool ecosystems are extremely sensitive to inter- and intra-annual environmental variability. The size and number of inundated basins, and therefore their associated biota, are directly correlated to the amount and timing of precipitation. Rainfall during the 2003 water year has been consistent with average recorded precipitation in San Diego over the past 153 years (Figure 2; http://nrm.dfg.ca.gov/documents/ContextDocs.aspx?cat=BIOS&sub=ds188 ), and the majority of basin areas were recorded during March when cumulative precipitation for 2003 equaled cumulative average rainfall. Based upon the amount and timing of rainfall, it is believed that the data gathered for 2003 represents a "typical" year for vernal pool biota. Spatial and attribute data were compiled by the City of San Diego Planning Department Multiple Species Conservation Program staff or their consultants. METHODS including SPATIAL DATA CAPTURE METHODS: Spatial and attribute data were collected by visiting each site following storm events with recorded rainfall of 0.33 inches or more from January through May 2003. At or near maximum inundation, individual basin boundaries were recorded using a differential sub-meter GPS, and the following attributes were documented: site name; Bauder identification number (if any); vernal pool identification number (assigned by series at time of survey); date; time; state of inundation; comments; presence/absence and percent cover for Eryngium aristulatum (San Diego button celery), Navarretia fossalis (spreading prostrate navarretia), Orcuttia californica (California Orcutt grass), Myosurus minimus (little mousetail), Pogogyne abramsii (San Diego mesa mint), and Pogogyne nudiscula (Otay mesa mint); presence/absence for Branchinecta spp. (unidentified fairy shrimp), Branchinecta sandiegonensis (San Diego fairy shrimp), Branchinecta lindahli (versatile fairy shrimp), Streptocephalus woottoni (Riverside fairy shrimp), tadpoles/metamorphs (unidentified), Spea hammondi (tadpole/metamorph/adult Western spadefoot toad), Bufo boreas (tadpole/metamorph/adult Western toad), and Hyla regilla (tadpole/metamorph/adult Pacific tree frog). Where possible, the spatial and/or biological data were obtained from current consultant survey information. In cases when such data were not available, information was collected during site visits by City staff. Dates and personnel information for data collection are available in Appendix A ( http://nrm.dfg.ca.gov/documents/ContextDocs.aspx?cat=BIOS&sub=ds188 ). Specialized software combined with a sub-meter global positioning system (GPS) were used to precisely record each basin. Two hand-held devices were used in spatial data collection: Trimble TSC1 datalogger using Asset Surveyor version 5.00, and Compaq iPaq running ESRI's ArcPad 6.0. Each collection device was linked to a Trimble Pro XR sub-meter GPS receiver. The Pro XR utilizes real-time differential GPS correction which results in increased field accuracy while eliminating the need for post-processing data correction. In the office, spatial data and attributes from each collection system were combined using Trimble's Pathfinder Office 3.00 and ESRI's ArcView 3.3 software, respectively. When observed, the presence/absence of the following amphibians (tadpoles, metamorphs, and adults) were noted at each basin: Bufo boreas, Hyla regilla, and Spea hammondii. In addition, presence/absence surveys were conducted for fairy shrimp. Species were identified to genus in all cases of presence, and U.S. Fish and Wildlife Service protocol surveys were used to identify fairy shrimp to species in 100 randomly selected basins. Species identified include: Branchinecta sandiegonensis, B. lindahli, and Streptocephalus woottonii. A comprehensive list of vernal pool plant species present by series per Corps vernal pool indicator guidelines (U.S. Army Corps of Engineers, Los Angeles District, Regulatory Branch, November 1997) and vernal pool plant species listed in Tables 6a and 6b in Zedler's Ecology of Southern California Vernal Pools: A Community Profile (1987) was prepared by a consultant. Each site was surveyed twice by an experienced vernal pool biologist during the winter and spring of 2003. Surveys were timed to coincide with 1) the highest level of basin inundation, and 2) optimal flowering time later in the season for detection and identification of both early and late showing vernal pool species. Wetland and upland species present at each complex were also surveyed. At sites where one or more of the following endangered, threatened, or MSCP covered species occur, City staff estimated percent cover for each species in each vernal pool: Eryngium aristulatum spp. parishii, Navarretia fossalis, Orcuttia californica, Myosurus minimus, Pogogyne abramsii, and/or Pogogyne nudiscula. Staff visits were scheduled to coincide with the maximum foliage of vegetation, and multiple visits were necessary in many cases. Estimates were derived from the California Native Plant Society percent cover worksheet, and were calculated based on vernal pool basin area. Estimated relative percent cover was grouped in the following classes to track major changes in population size over time: <1%, 1-5%, 5-10%, 10-25%, 25-50%, 50-75%, 75%+.
