|California Invasive Plant Council
20th Annual Symposium
Cal-IPC is hosting their 20th annual symposium at the Granlibakken Resort in Tahoe City, CA October 5-7th.
|The theme of this year's Symposium is Invasive Plants and Ecological Change. We have invited speakers to address the myriad types of human-influenced changes to the natural environment that impact invasive plant management, including changes in soils, fire, nitrogen deposition, and, of course, climate change. Registration and further details can be found here.

Releases Cost Survey Results for Invasive Plant Management
Cal-IPC recently conducted a survey of 84 agencies and organizations to
|estimate total direct costs for control, monitoring, mapping, and outreach statewide. The final total came to $82 million. See the flyer summarizing the details here.
|California Invasive Species Council
Announced At World Ag Expo
California officials today announced a
coordinated effort to prevent and
control harmful invasive species
infestations throughout the state.
| The California Invasive Species Council will assist in minimizing the negative effects of non-native species on the state’s agriculture, lands, natural resources, and waterways in rural and urban environments.
“The Invasive Species Council will protect California’s
consumers and our environment from destructive pests,
plants and diseases that also threaten our food supply,”
said Secretary A.G. Kawamura of the California
Department of Food and Agriculture, chairman of the
council. “Coordinating California’s resources will
maximize our opportunities to protect against harmful
non-native species that will destroy our forests, scenic
wildlands and waterways,” said Secretary Chrisman.
The council will appoint a California Invasive Species
Advisory Committee (CISAC) tasked with making
recommendations to prioritize an invasive species rapid
response plan. The committee will take input from local
government, tribal governments and federal agencies,
as well as environmental organizations, academic and
science institutions, affected industry sectors and
impacted landowners. For more information on invasive
species please visit the CDFA website. (Details)
|Burbank Students From
Clark Magnet High Undergo
Weed Mapping Project
Plant invaders were the target Sunday for Yeva
|Mirzakhanyan, who was roaming the trails of Stough
Canyon armed with a hand-held satellite mapping
system and a list of species. The 16-year-old junior at
Clark Magnet High School is part of a team of students
who have been using global-positioning-system
coordinates to mark the locations of invasive plants —
species that are not native to the region and hurt local
ecosystems, her teacher, Dominique Evans-Bye, said.

|Los Angeles County
WMA New Website
With support from the LA
|Commissioner's Office, the LA County Weed
Management Area has recently developed a new website
with up-to-date project and resource information. The
website can be found at www.lacountywma.org. Please
sign up on the WMA e-list to be notified of upcoming
meetings, events, and funding opportunities.
|NPS Develops Brochure for
Terracina Spurge Awareness in the
Coastal Areas of Los Angeles County
The National Parks Service recently
finished an outreach brochure to educate
local residents about the growing
Euphorbia terracina problem in the coastal
areas of Los Angeles (and now Ventura)
County. The Watershed Council assisted
NPS and Palos Verdes Peninsula Land
|Conservancy with the brochure layout and design.
Approximately 5000 brochures will be mailed to residents
living in the Wildland Urban Interface (WUI) of the Santa
Monica Mountains. Another 5000 brochures will be
distributed by NPS at events and the NPS Visitor Center
in Thousand Oaks. The WeedWatch program also
has a small amount on hand to distrubute to agencies
and organizations for outreach events. (See our outreach
page for details). Funding for this outreach program was
provided through the State WMA program.
|City of Oceanside Bans Three
A City Council majority April 18th
outlawed three invasive plants: arundo, tamarisk and pampas
grass ---- in an effort to reduce
the risk of fire and flood.
|Mayor Jim Wood, Councilwoman Esther Sanchez and
Councilman Rocky Chavez voted for the ban, which allows
Oceanside to direct property owners to remove the
problem plants. If those orders aren't followed, the city
can do the work and send the property owners the bill, a
city report states. (Full article here...)
|Gardening and Environmental Groups Try To Weed Out
WEED. We need only one syllable to differentiate friend from foe
| in our gardens. Yet the word seems inadequate for a new generation of weeds -- plants that we find beautiful or delicious when we cultivate them but that have escaped into the wild to potentially catastrophic effect.
No single source tells the story of the shifting definition quite so methodically as "Weeds of California and Other Western States." When UC Davis weed scientist Joseph M. DiTomaso published the two volumes in 2007, they included more than 700 specimens, just about every plant that has stung, inconvenienced or merely displeased people this side of the Rockies. There in the 1,800-plus-page rogues' gallery, many of our classiest nursery salads and ornamentals have rap sheets. Nasturtiums, weeds? Ice plant? A weed? (Full article here...)
|NPS Develops Commercials for Euphorbia terracina Awareness
in Santa Monica Mountains
The National Parks Service
recently finished a series of
humorous educational videos
|about the growing Euphorbia terracina problem in the
Santa Monica Mountains. These short ads will be aired
on local cable channels within the Los Angeles region.
Funding for this outreach program was provided through
the State WMA program. One of the ads can now be
seen on YouTube.
|Non-Native Plants May Be Banned By Council
|ENCINITAS – Think that pampas grass adds flair to your yard? It might, but
|City Councilwoman Maggie Houlihan wants to ban it and other non-native plants from all new developments in Encinitas to save the city's wildlife habitats.
Invasive plants push out native species and deprive wildlife of their food and nesting places, she said.
Some are fire hazards, and others are water hogs, said Councilwoman Teresa Barth, Houlihan's environmentalist ally on the council.
"There is no prohibition against planting this stuff,” Houlihan said. “There are such attractive alternatives to invasive plants.”

|LA County WMA Awarded CDFA Funding
As part of the Los Angeles County WMA, The Palos Verdes Peninsula Land Conservancy, the Santa Catalina Island
| Conservancy, and the Santa Monica Mountains National Recreation Area were recently awarded funding through a two-year grant from CDFA. Proposed work from the WMA will include: a) eradicating Euphorbia terracina at three locations (within Solstice Canyon and along the Palos Verdes Peninsula), b) produce an educational campaign (brochures, posters, and a TV commercial) focusing on identification of E. terracina, its negative impacts, and effective control measures, and c) completely eradicate all known populations of yellow star thistle (Centaurea solstitialis), Veldt grass (Ehrharta calycina), saltcedar (Tamarix ramosissima), and periwinkle (Vinca major) from Conservancy property (42,000 acres) on Catalina Island.
New Study Shows the Economic Benefits of Preventing Invasive Species
WASHINGTON – A new study shows that screening for potentially harmful foreign plant species before they are imported is more economically beneficial than fighting them after they take root in new areas. Read the full article here.
