One was observed about 25ft off the trail in coastal sage scrub (Figure 3). The other involved two gnatcatchers traveling together about 100ft from the work. ●All biological resources were monitored and no adverse impacts occurred. Weather Conditions Conditions:Sunny, clear and brisk. Temperature:44 F Humidity:83%Wind:ENE 3 mph Cloud Cover %:0 Temperature:64 F Humidity:44%Wind:W 5 mph Cloud Cover %:0 Endemic Environmental Services Construction Activity Name of Contractors Performing Work:DD Systems Relevant Person(s) in charge of construction:Danny Start Time:0700 End Time:1540 Is project work activity compliant?Yes Construction Activity Notes/Equipment Used:Hand tools, Mini excavator, 249D Skid steer - The excavator was parked on the trail overnight and was used to dig stairs along the south loop trail. They were excavating creating new ground disturbance (Figure 1 & 2). - The skid steer was used to transport supplies to the crew. - Another landscape/maintenance crew called MCE was making road and trail repairs using a bobcat from the main staging area behind the homes to the start of the trail improvement work area. They were digging into the berms along the side of the road/trail. Endemic Environmental Services 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:Coastal California gnatcatcher (Polioptila californica californica) Time of Observed Listed Species:0903; 1419 GPS Location of Listed Species (if applicable):1) 34.00282, -117.79906 2) 34.00303, -117.79909 Description of Listed Location:Observed in the disturbed coastal sage scrub dominated by black sage (Salvia mellifera) and dead mustard (Brassica sp.). Bio-monitor Notes:At 0903, a female type California gnatcatcher flew upslope from the east toward the trail where the monitor was standing. The gnatcatcher was originally about 25 ft downslope of the trail and then flew about 50 ft along the trail to the WSW. At the time the bird was observed the mini excavator had been turned off. The bird was observed for about three minutes before dipping down into the black sage as a hiker approached. At 1419, two female type California gnatcatchers flew into the work area from the east and came within 100 ft of the work. The mini excavator was digging stairs and the birds were downslope to the WSW, next to the figure-eight loop in the trail. They were traveling together, foraging, moving through the CSS. They did not appear disturbed by the work. They moved away toward the large oak tree along the trail and then out of view. The observation lasted 3 minutes. Species Common/ Scientific Name:Cactus Wren (Campylorhynchus brunneicapillus) Time of Observed Listed Species:not recorded GPS Location of Listed Species (if applicable):not recorded Description of Listed Location:Prickly pear scrub Bio-monitor Notes:The bird was not near any of the construction activities and did not appear disturbed by the work. Endemic Environmental Services Species Take Section Was there a take of any listed or regulated species?No If yes, then: What type of take occurred? Species Common Name/ Scientific Name: Age/Class: Gender: Did take occur due to project work activity? GPS Location of Take (if applicable): Description Location of Take: Bio-monitor Notes Endemic Environmental Services Nest Findings Were there any nests observed on or near project site?No If yes, then: Were nests active or non-active?
