Removing Red Sesbania - Restoring Creek Biodiversity
by Frank Wallace
Since 2001, each Creek Week Cleanup Day has included work sites
to remove red sesbania, an invasive plant that grows naturally
in southern South America. This plant is spreading rapidly along
many creeks in north Sacramento and along the American River,
threatening the existence of native plants used by wildlife for
food and shelter. This plant grows right next to the creek and
is spreading into sand bars in the water, increasing the risk
of flooding. The California Department of Food and Agriculture
considers it a serious threat to biodiversity, designating it
a red alert plant
On Cleanup Day, Sacramento Weed Warriors, a volunteer stewardship
project of the California Native Plant Society, supports a limited
number of work sites, providing a site leader and all the tools
and gloves needed for removing sesbania. Each site leader provides
an introductory orientation regarding removal techniques and safe
use of tools. Target sites will be listed on the Urban Creeks
Council web site - so if your family, youth group, or student team
wants to participate, you can look for a site closest to your home
or school. If you want to volunteer, please contact Frank Wallace,
SWW director, at 427-5694. Students as young as 10 have
participated previously.
Sesbania removal projects are usually a lot of fun for youth groups.
These projects develop teamwork and friendships since there are
several tasks of varying difficulty: First, the upper portions
of the plant are cut off using pruning saws and loppers; then
weed wrenches and shovels are used to remove the roots; and finally
the vegetation is cut up and carried to a location away from
possible flooding,-where it will decompose naturally. Volunteers
usually rotate among jobs learning how to use the different tools.
A group of 10-15 participants can make a big contribution to this
invasive plant control effort.
Since new sesbania plants will sprout throughout the year,
Sacramento Weed Warriors will be supporting removal work
groups and monitoring teams throughout the spring and summer.
If you have a school community service project, a youth group,
a business team, or a community organization that would like
to volunteer, please call Frank Wallace.
