San
Francisco Public Utilities Commission crews recently launched a series of short
projects to control invasive weeds on parts of its Peninsula Watershed land
near the Sawyer Camp Trail for approximately a one-mile stretch slightly north
of Mile Marker 1. The first project, which started Monday, February 18, is now complete. The trail remained open throughout the work period.
The
weed control is being done to preserve and enhance the native grasslands that
were seeded in late 2016 as part of a continuing long-term habitat restoration
program in various areas throughout the watershed. The 2016 seeding followed the removal of
acacia trees and other large, invasive vegetation that had displaced the
watershed’s historic native habitats near the trail and at other watershed
sites.
Subsequent
intermittent short periods of weeding and other vegetation control measures
will occur in the Sawyer Camp Trail area in the course of the next couple of
years or more. Trail users will be notified in advance.
The
approximately 36-square-mile Peninsula Watershed is home to a diversity of
long-time coastal habitats, ranging from conifer and oak forests to chaparral,
grasslands, and marsh. In all, they harbor an abundance of native plant and
animal life, including a high concentration of rare, threatened or endangered
species. The watershed is also a State Fish and Game Refuge.
