Summary

The data are part of ongoing studies of the wildlife resources at DFW units throughout the NCR. These surveys were supported by the State Wildlife Grant program.

Description

These data represent wildlife observations from surveys in 2004 and 2005 of 56 different Wildlife Areas and Ecological Reserves (units) managed by the California Department of Fish and Wildlife (DFW) in the North Central Region (NCR). These wildlife species were observed by trained observers from the NCR's Resource Assessment Program (RAP) doing walking surveys through discrete habitat patches at the different DFW units. These wildlife species were observed from 374 different transects conducted between 14 July 2004 and 12 July 2005. There are 6,185 detections of 266 different taxa including amphibians, reptiles, birds, and mammals. Wildlife observation data are linked to the transect data with a common variable that represents the identification number of each transect (Route Number).

Supplemental information
Methodology Trained observers walked linear and nonlinear, irregular length transects confined within discreet habitat patches within each unit observing and recording all species of wildlife seen or heard during the surveys. The surveys were conducted during the daylight hours, and transects generally took 1-2 hours to complete. Observers selected transects to sample wildlife in habitat patches that were representative of the respective habitat within the individual CDFG unit. Surveys were conducted during the fall, winter, spring, and summer seasons, and 1-3 surveys were conducted at each unit. Winter access to several units at higher elevations in the Sierra Nevada was not possible. Binoculars were used to aid identification, and all habitats were classified using the CWHR habitat classification system. Transects were delineated after the surveys were done by tracing a polyline between GPS waypoints taken at the beginning and ending of the transects. At least one patch of each habitat type was surveyed at each unit. Detections of wildlife are only those of animals that were stationary and using terrestrial or aquatic habitat components and were not flying over the habitat patches. Surveys were done mostly of DFG units within the NCR that lack permanent staff. Spenceville and Hallelujah Junction, however, both units with staff, were surveyed.

HideScope of quality information


Data quality report - Conceptual consistency
Measure description
These observations represent detections of individual wildlife taxa at 56 different DFG units within the NCR. Some transects where aquatic and terrestrial habitats meet spatially overlap because transects for aquatic habitat could not be delineated in the water. In addition, some transects spatially overlap, including terrestrial habitats that are adjacent to aquatic habitats, and transects that were resurveyed at different dates. Terrestrial and aquatic wildlife were detected in aquatic and terrestrial habitats, respectively, due to aquatic and terrestrial habitat components found within these habitats that resulted in these species using habitats for which they normally could not use. For example, many species of waterbirds were found in grassland and riparian habitats because water features too small to be individual habitats were found in these terrestrial habitats. Contrarily, species of terrestrial wildlife were found in aquatic habitats because terrestrial habitat components, such as trees, were found in aquatic habitats.

HideData quality report - Completeness omission


Data quality report - Quantitative attribute accuracy
Measure description
It is assumed that these species were accurately identified by vocalization and/or visually, and that they were counted accurately. Also, the spatial accuracy of the transects is considered accurate to + 10 m, but the delineated transect may cross patches of habitat that are different from the surveyed habitat because the transect was drawn as a straight line. In addition, transects may traverse aquatic areas where the observers could not traverse. It assumed that the observed wildlife were confined solely to the patch of surveyed habitat.

Measure description
The spatial accuracy of the transects is considered accurate to + 10 m, but the delineated transect may cross patches of habitat that are different from the surveyed habitat because the transect was drawn as a straight line. In addition, transects may cross areas, such as open water, that observers could not traverse. These are artifacts of the transect delineation process.

Lineage

Process step
When the process occurred 2007-05-01
Description
Data were gathered in the field, and were then entered into Excel as raw field data from the surveys. GPS waypoints were marked in the field at the beginning and ending of each transect. The transect shapefile was created by connecting the beginning and ending waypoints of the surveys to form a polyline GIS feature. Some transects were drawn without any waypoints or with 1 waypoint so their accuracy is less than transects drawn with 2 waypoints.

Overview Description
Entity and Attribute Overview
The transects represent the routes taken by trained observers through discreet habitat patches for wildlife surveys conducted between 14 July 2004 and 12 July 2005. The wildlife detections are taxa that were detected by sight or sound during the surveys. There are 6,185 detections of 266 difference taxa from 374 transects from 56 different Wildlife Areas and Ecological Reserves in the NCR. Data from the transect shapefile and detection Excel file relate to each other through the field "Route Number." The shapefile contains the spatial data for the transects, while the Excel file contains the biological data with the wildlife detections.
