Ivy Attacking Trees Along Woodland Ave.

Dear Jesse,

Along Woodland Avenue adjacent to San Francisquito Creek, invasive Algerian
and German Ivy is attacking our native oak and bay trees. Unchecked, this
ivy will eventually kill some of these magnificent natives that we value so
much.

In some areas, private property owners have done a great job of keeping the
ivy trimmed off the oaks, but in other areas, the huge old native oaks are
being endangered by ivy growing into their canopies.

Last year, a huge branch and a big part of the trunk of an stately old oak
tree located across from 1285 Woodland broke off and fell into the creek.
This was caused in part by the extremely heavy accumulation of Algerian Ivy
that had accumulated in the canopy. While the creek channel was cleared,
nothing has been done yet to address the ivy that is still accumulating in
the canopy.

All of us that love the native oak and bay trees along the creek would
appreciate the City assisting in maintaining the health of these beloved
roadside and creekside oaks by periodically removing excessive ivy
accumulations.

Our Council may wish direct you to partner with Acterra to address this and
other invasive roadside/creekside problems on an ongoing basis.
Menlo-Atherton students and Menlo Park citizens along with other Acterra
volunteers, with support from the City of Palo Alto, are slowly totally
transforming the Palo Alto Avenue side of the creek by removing invasive
plants and establishing natives. The City of Menlo Park should do the same
along the Woodland Avenue side. Please let me know if you would like to
meet with me or representatives of Acterra to explore this issue and
opportunity further.

With old oak tree as our city logo, lets take care that the beautiful oaks
we have!

Warm regards,

- Jim Wiley

"Ivy vines form dense carpets of vegetation that can cover native
vegetation as well as open soil. This dense groundcover can deprive native
plants of light and nutrients and reduce germination of the native
seedbank. Evenually even large trees can be killed by ivy climbing into
their canopies." www.cal-ipc.org/ip/management/wwh/pdf/19629.pdf

Ivy along Woodland Avenue are enclosed.
