DAILY BIO-MONITORING REPORT
Date:11/14/22 Day:Monday
Project/Stage of Project:Diamond Bar Canyon Loop Trail Improvement, trail maintenance
Name of Bio-monitor:Phillip Samples
Location:Diamond Bar
Location Description:Coastal Sage Scrub and Coast Live Oak Woodland, behind residential area
Map # (If applicable):N/A
Bio-monitoring Activity
Start Time:0700 End Time:1300
Bio-monitoring Notes:
●The crew used the excavator to dig and level a 9 x 12 feet section on the north loop trail;this site will be
used for a shade installation at a later date (Figure 1).
●Approximately 4 square feet of prickly pear vegetation was removed from the trail for safety and
aesthetic reasons (Figures 2 & 3).
●The crew used the excavator to dig a 10 foot v-swale at the intersection of the central loop -south loop
trail (the v-swale will be installed at a later date).
●The crew assembled and staged several gabion cages on the southern trail (Figure 6).
●All biological resources were monitored and no adverse impacts occurred.

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.
