POM = Otay Preserve Owner Manager (Joint Exercise of Powers Agreement between City Chula Vista and County San Diego)

Private = Privately owned

TNC = The Nature Conservancy

USFS = US Forest Service

USFWS = US Fish and Wildlife ServiceManagement Status

CodesM = Population or habitat is fully managed

SM = Site is managed but population or habitat is not managed

PM = Partial management of population or habitat

NM = No management

UM = Unknown management status

UTMNAD83N, UTMNAD83E, StatePlaneN, StatePlaneE, Latitude, Longitude = X,Y coordinates should be entered into the columns corresponding to the original data source coordinate system. Any additional information on datums or projections should be provided in the comments column. Coordinates were converted to Latitude and Longitude.

Accuracy:High: Coordinates from GPS or shapefile

Medium High: Coordinates derived from maps within paper reports

Medium: Area within preserve based on verbal/text description

Low: Location known only to large geographic area (e.g. Otay Mesa) or preserve level

PopSize = number of individuals estimated or counted or in the case of some plants, the number of locations where mapped which may contain multiple individuals/location (to be specified in Survey Type)

PopArea = measured with GPS or ARCGIS polygon in m2

NoLocations = Number of mapped or counted locations with multiple individuals present at each location. If there is one population at a location and the number of individuals have been counted, then there is no need to enter anything in this column.

Survey Method

Census = Count of all individuals

Index = Conduct cout of individuals or % cover within index plots to monitor population fluctuations over time.

Map = Map point locations of plants or animals with GPS or on hard copy map and input as point data into ARCGIS. A location can represent one individual or multiple individuals.

Other = Other type of survey method not described here

PartialEst = Count portion of site and use this to estimate remaining individuals on site and derive an estimate of the total number of individuals.

Perimeter = GPS perimeter or map boundaries of population on hardcopy map and input as polygon data into ARCGIS

PresentNoDetect = Survey was done to determine if species was present or not detected during site visit.

PtCount = Conduct a point count survey to determine abundance and richness of bird community

QuadratEst = Randomly place a quadrat and count number of individuals to estimate population size within a measured area

Transect = Conduct a line or belt transect to count number of individuals (e.g., birds, herps) or measure cover of plants

TransectEst = Randomly place transects and count number of individuals to estimate population size within a measured area

Trap = Use traps to capture small mammals and estimate size and distribution of population

Unknown = Unknown survey methodVisual

Est = Estimate number of individuals within defined area (e.g., releve). Estimate usually involves rounding or estimating within a category of abundance.

Population Status Codes (PopStat):ExtantExtirpatedPresumed ExtantPresumed ExtirpatedUnknownTranslocation

(Transloc):Yes = Transplanted population or individual

Blank = Naturally occuring pop or not thought to be translocated

Threats = Description of the threats/stressors that have been identified for that specific population.

Comments = Field included to clarify, describe in greater detail or provide additional information associated with that population or location.

Source1, Sourc2, Source3 = These columns are to document the sources of the information, with Source1 being the primary source, Source2 being the secondary source, etc.
