Summary

The goals of the San Diego Tracking Team (T) are to monitor the wildlife of specified open space preserves and land trusts in the San Diego area through the use of periodic track and sign count transects and to enhance environmental awareness, community involvement, and appreciation for local habitats by encouraging volunteer participation in the study. This dataset was created to support the determination of the following: 1) the presence or absence of certain rare species and other target species which can reflect the health of the ecosystem; 2) substantial changes in wildlife populations over time; and 3) the use of different habitats by the target species which could lead to the identification of critical habitat areas and corridors (Markovchick-Nicholls et al. 2008). It is intended that the information gathered by the T will be used to identify potential restoration and/or mitigation opportunities for important habitats and corridors in support of San Diego's Multiple Species Conservation Plan.

Description

The San Diego Tracking Team (T) is a non-profit organization dedicated to promoting the preservation of wildlife habitat in San Diego County through citizen-based wildlife monitoring coupled with environmental education programs. For 15 years, the T has conducted wildlife track and sign surveys to evaluate the health of key species, the connectivity of open space areas, and the efficacy of the city and county's Multiple Species/Habitat Conservation Plans. Scientific advisors from public resource agencies and academic institutions oversee the tracking protocol, and T data is used in planning transportation and urban development projects, as well as in studies on land use in fragmented habitats (Markovchick-Nicholls et al. 2008). Surveys are conducted by trained volunteers from all over San Diego County who together commit over 1500 hours per year to monitoring over 60 locations around the county. Transects are designated throughout specified open space preserves, land trusts, and other undeveloped lands in the San Diego area. Transects that were established after January 1, 2007 (TransID 60 +) are one kilometer in length and ten meters in width (5m on each side of trail center), and are divided into four sections of 250 meters in length. Any side trail, streambed, or other site with favorable tracking conditions easily visible or within ten meters of the trail is investigated as part of the transect. Prior to 2007, transects were laid out to be approximately one mile in length, 30 feet in width, with variable length sections.Transect teams, which consist of an experienced Transect Leader and from 1 to 6 trained volunteers, survey transects on a seasonal basis each year. Any track or sign identified from the following animals was recorded during surveys: coyote, mule deer, bobcat, gray or kit fox, raccoon, opossum, wood rat, badger, black-tailed jack rabbit, cougar, black bear, spotted or striped skunk, long-tailed weasel, ringtail and roadrunner. If a track or sign was observed, the location (transect number and transect section) and type of sign (scat, tracks, deer browse, evidence of predation, den/bed site, sighting) were recorded on data sheets. In addition, age of the sign (Fresh, less than two weeks old or Historic, more than two weeks old) was recorded. Additional data on presence of small mammals (cottontails, skunks, squirrels, or rodents) and habitat use were recorded as well as tracking conditions.This dataset represents a summary of T data collected from 2007 - 2010. For data collected from 1996 - 2006, please see dataset ds442.

Supplemental information
DATA COMPILATION HISTORY: The San Diego Tracking Team (T) has conducting tracking surveys in San Diego County since 1996. Tracking data were recorded on paper in the field and entered into an MS Access database by the volunteer Database Coordinator. QA/QC of the data is conducted after data has been entered into the T database. SPATIAL DATA CAPTURE METHODS: GPS coordinates of the starting point of each transect segment were collected in 2000 and for all transects initiated after 2000, recorded on the first survey of each transect. Spatial data of transect section start points were compiled by Transect Leaders and are maintained separately from the Access database. Spatial data were collected using hand-held GPS units and projected in either NAD83 or WGS84. Midpoint coordinates of each segment were calculated by Jonah Evans of Nature Tracking by averaging the segment start coordinates (Evans 2008). This data was later uploaded into the T Access database. Spatial data were joined with tracking data from the T database and a spatial layer was developed as part of the Southern California Data Integration Project. Data were imported into ArcGIS 10.0 to create the spatial data layer and associated metadata. REFERENCES: Markovchick-Nicholls, L., H. M. Reagan, D. H. Deutschman, A. Widyanata, B. Martin, L.

Data quality report - Quantitative attribute accuracy
Measure description
A preliminary cross-validation study of tracker bias was conducted by Lisa Markovchick-Nicholls of San Diego State University in 2006 (Markovchick-Nicholls 2006). Random transect sections were surveyed by Barry Martin, the most experienced tracker involved in the T, and then by Transect Leaders, immediately after Martin completed the survey. The following determinations were made in this study: 1. Although agreement (between Martin and other transect leaders) on the exact number of species in each section is lower than desirable, overall agreement on the community composition of species present in sections was reasonable. 2. Trackers appear to over-estimate the number of species in sections with low numbers of species (as compared to Martin) and under-estimate the number of species present in sections with high numbers of species. 3. Since overall community composition of sections appears slightly more reliable than the number of observations per species in each section, evaluation of the data as presence / absence data rather than numerical data may be advisable.
