APPENDIX D. INTUITIVE CONTROLLED SURVEY and SPATIAL DOCUMENTATION
Intuitive Controlled Survey
Intuitive controlled surveys are intensive searches in those portions of the project area with the highest potential for locating the target species. The surveyor walks through the project area enough to see a representative cross-section of all the major habitat types and environmental conditions, looking for the target species while en route between different areas. When the surveyor arrives at an area of probable habitat (that was predetermined in the pre-field review or encountered during the field visit), an intensive search should be made within the probable habitat areas (Figure 2).
Spatial Documentation of Extent of Survey
To facilitate accurate information transfer into a GIS system, spatial documentation of the area surveyed should be precisely recorded as shown in Figure 2 on a 7.5 minute (1:24,000) USGS topographic map in black ink. Designate plot locations where taxon encountered with an + and corresponding plot number.
