Weather Conditions Conditions:Sunny, clear and brisk. Temperature:45 F Humidity:44%Wind:SW 4 mph Cloud Cover %:10 Temperature:66 F Humidity:23%Wind:NE 7 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:1530 Is project work activity compliant?Yes Construction Activity Notes/Equipment Used:Hand tools,Mini excavator, 249D Skid steer -The excavator was used to dig and level a 9 x 12 foot area along the north loop trail,a 10 foot long and 1 foot deep v-swale at the intersection of the central and south loop trails,and to remove prickly pear cactus (Opuntia littoralis) from the south loop trail (Figures 1 & 4) -The skid steer was used to transport supplies to the crew. -Gabion assembly using hands -Hammers to stake Endemic Environmental Services Biological Resource Findings Were there any listed species observed on or near site?No If yes, then: Was listed species impacted due to work? Species Common/ Scientific Name:Time of Observed Listed Species: GPS Location of Listed Species (if applicable): Description of Listed Location: Bio-monitor Notes: 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? Nest(s): Species (If identifiable): Time Observed:Nesting Status: GPS Point of Nest: Location Description of Nest: Biomonitor Notes: Other Nest Notes: Endemic Environmental Services Nest Removal Section Were there any Nests removed?No If yes, then: Was the MBTA Nest active or non-active? Time of Nest Removal? Why was the nest removed?: Species Scientific/ Common Name: GPS Location of Removed Nest (If applicable): Bio-monitor Notes: Endemic Environmental Services Wetlands and Jurisdictional Waters of the U.S. Are Wetlands or Jurisdictional Waters of the United States Present?No If yes, then: What Watershed? Were Wetlands or Jurisdictional Waters of the United States impacted by project work activity?No What type of impact occurred? Bio-monitor Notes: Endemic Environmental Services Vegetation Impact Section Was vegetation impacted by project work activity?Yes If yes, then:Coastal Prickly Pear Cactus (Opuntia littoralis) Habitat Type:Coastal Prickly Pear Cactus Scrub Type of Vegetation Impacted:Coastal Prickly Pear Cactus What type of impact occurred?Permanent removal Square Footage of Impacted Area:4 square feet Bio-monitor Notes: -Cactus was removed because it was present on the trail and posed a safety/aesthetic concern to future recreational hikers (Figures 2 & 3). Endemic Environmental Services Non-Listed Species Section Were there any non-listed species observed?Yes If yes, then: Species Common/ Scientific Name: Red-tailed Hawk (Buteo jamaicensis),House Finch (Haemorhous mexicanus),California Towhee (Melozone crissalis), California Scrub-Jay (Aphelocoma californica),American Robin (Turdus migratorius), White-crowned Sparrow (Zonotrichia leucophrys), Mourning Dove (Zenaida macroura), Rock Pigeon (Columba livia), Common Raven (Corvus corax) Bio-monitor Notes: From 0700 to 0900 the construction crew assembled gabion cages on the south loop trail. At 0900 the weekly meeting commenced and the biologist, along with the rest of the stakeholders, walked the length of the south loop and north loop trail for an update on project progress. Stakeholders identified the importance of removing approximately 4 square feet of cactus scrub and it was later confirmed by the Endemic project manager, Alex Eagleton, that this patch of vegetation could be removed. Stakeholders then identified the site of a shade installation on the north loop trail. Lastly, stakeholder identified the site of a v-swale installation on the central loop - south loop intersection. Following this meeting, Danny used the excavator to finish all the aforementioned tasks. The biologist then confirmed that no new digging or vegetation removal will occur for the remainder of the day.
