Biological Resource Findings
Were there any listed species observed on or near site?Yes
If yes, then:
Was listed species impacted due to work?No
Species Common/ Scientific Name:Cactus wren (Campylorhynchus brunneicapillus), California gnatcatcher
(Polioptila californica)
Time of Observed Listed Species:0800
GPS Location of Listed Species (if applicable):34.003211,-117.802361 (gps point applies to both species)
Description of Listed Location:At the intersection of Prickly pear scrub and Coastal sage scrub habitats
Bio-monitor Notes:The Cactus wren was seen foraging,and then calling from atop a bush. The California
gnatcatcher called once from some artemisia South of the trail, then left the area.
A single time and GPS location are listed because both species were heard within 3 minutes of one another in the
same area.
