Bio-monitoring Activity
Start Time:0700 End Time:11:30
Bio-monitoring Notes:
●No new vegetation impacts or ground disturbance occurred today.
●The excavator was parked on the trail overnight.
●The crew worked on adding more pipe to the water line (Figure 1),and started working on the stairs at
the end of the trail (Figures 2 & 3).
●I reminded Danny that it is not allowed to have the excavator in use while the skid steer is traveling
along the trail to another location.He replied that it is going to happen almost every day.I asserted it was
in the permit and must be followed.
●I talked to Danny about pruning cactus in the damaged area,as to make space and avoid destroying
roots. He was receptive.
●One coastal California gnatcatcher was heard calling in the distant coastal sage scrub (Figure 5).
●All biological resources were monitored and no adverse impacts occurred.
