DAILY BIO-MONITORING REPORT
Date:2/6/23 Day:Monday
Project/Stage of Project:Diamond Bar Canyon Loop Trail Improvement, Project conclusion. Final Biomonitor
visit
Name of Bio-monitor:Alex Eagleton
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:01:00 pm End Time:02:30 pm
Bio-monitoring Notes:
●The biologist surveyed the trail edges to determine the final permanent impacts to vegetation.
○Total permanent impacts to vegetation was 0.100 ac. Subtotals can be found in the vegetation
impacts section.
●Fencing had been completed (Figure 2). Hydroseeding had been done on some of the disturbed slopes
near the trails (Figures 3 and 6). Staging area was gone and materials had been removed from the site.
●The weekly site meeting between city, bio, and engineering occurred at 1pm. Work has concluded.
●All biological resources were monitored and no adverse impacts occurred.

Vegetation Impact Section
Was vegetation impacted by project work activity?Yes
If yes, then:
Habitat Type:Coastal sage scrub, prickly pear scrub, California sagebrush-black sage scrub
Type of Vegetation Impacted:various plants along trail edges
What type of impact occurred?Permanent
Square Footage of Impacted Area:See below
Bio-monitor Notes:Today the biologist evaluated parts of the trail where soil had spilled over and covered the
vegetation due to work activities. Now that trail edges are finalized, and cleanup attempts had been made in those
areas, the biologist determined that most of those areas received permanent impacts (Figures 1, 3, 4 and 5). The
total permanent impacts to vegetation for this project are listed below, and can be visualized using the maps in
the appendix (Maps 1-4).
Disturbed Coastal Sage Scrub: 0.0657 ac
CA Sagebrush - Black Sage Scrub: 0.0173 ac
Coast Prickly Pear Scrub: 0.0170 ac
Total Permanent Veg Impact (exclude mustard): 0.100 ac
Mustard: 0.0186 ac
