The Santa Margarita
and San Luis Rey Watersheds Weed Management Area
was formed to provide support, coordination and funding for management of
invasive non-native plants and restoration of native riparian habitat within
the Santa Margarita and San Luis Rey watersheds in San Diego and Riverside
Counties. This web site provides information on our projects, control
methods and invasive non-native plants of concern.
1) Provide the
information, expertise, organization and support necessary for the control
of invasive non-native plants in the Santa Margarita and San Luis Rey
watersheds on a watershed scale. This means working from the top of the
watershed towards the bottom so that control sites are not re-infected by
2) Continue the control
of Arundo donax (giant reed) on the San Luis Rey
watershed. As of November 2000 the WMA has treated Arundo from the
uppermost infestation on the San Luis Rey watershed (at Wilderness Gardens
County Park) downstream to Hansen Aggregates. Several control projects are
planned for 2001.
3) Develop funding
resources for the maintenance of the WMA and the continued invasive plant
removal efforts in the Santa Margarita and San Luis Rey watersheds.
4) Finish mapping Arundo
in the uppermost portions of the Santa Margarita watershed (i.e. above
Temecula) and use this information to guide the implementation of projects
to remove the remaining Arundo sources that are identified. These Arundo
plants jeopardize the success of downstream control projects.
5) Continue the
management, monitoring and re-treatment of Arundo control projects on the
Santa Margarita watershed initiated in Fall 2000.
6) Create a
comprehensive database that will contain all information on all completed
and pending invasive plant control projects and plant distributions in the
two watersheds. This information resource center will be used by the WMA
for compiling all mapping efforts into a comprehensive and accessible
format, to aid in developing invasive plant control plans, to provide the
information necessary in implementing specific invasive plant control
projects (e.g. sensitive species distributions), and as a means to monitor all
projects over the long-term. This resource will be accessed over the WMA's
7) Continue educational
outreach to increase awareness on the negative impacts of non-native
invasive species and the identification of these species. Outreach will be
done through holding meetings, attending meetings (local, regional, state),
the website, and local newspaper articles.
