T
hose working in ecological restoration have come a long way in the last ten years,
as has Cal-IPC itself. Like with other overwhelming environmental challenges, it
is not always easy to feel optimistic. But in looking at how far we have come in the last
decade, it is clear to me that major progress is being made.
In the year 2000, there many fewer professionals focused on management of invasive plants. There were only a handful of stewardship intern programs, native plant
nurseries, and private restoration firms. Cal-IPC had half the number of members it
does today, and no staff. In 2000, the first legislation to fund local Weed Management
Areas in California had just passed. Since then the program has provided $10 million
throughout the state to local management projects.
For years, nurseries and land managers were unable to come to terms regarding invasive plants used in horticulture. Working to stop the use of invasive plants in landscaping was often confused with a demand to use only natives. Today the Don’t Plant a Pest
campaign and the PlantRight partnership have built a strong foundation for addressing
this major pathway for spreading invasive plants.
In 2000, few organizations had inventoried and mapped the invasive plants on their
lands. GIS and GPS tools were breaking into the mainstream and data standards for
weed mapping were being worked out. Online geospatial tools were crude. Today, land
managers consider mapping to be an integral part of their weed work. Calflora and the
Bay Area Early Detection Network have developed handy online reporting tools for
new finds, and Cal-IPC is combining statewide distribution mapping with climatic
modeling to anticipate weed spread. New tech tools are being developed every year.
Ten years ago, agricultural and environmental organizations were finding common
cause in addressing invasive plants and formed the California Invasive Weeds Awareness
Coalition, which would begin sponsoring Invasive Weeds Awareness Day at the Capitol
in 2004. State and federal agencies formed the Interagency Noxious Weed Coordinating Committee, and county Agricultural Commissioners were taking on the new work
of organizing WMAs. Today the state has a formal Invasive Species Council with a 24member advisory committee bridging different taxa and stakeholder communities. We
aim to produce a comprehensive strategic plan that for endorsement at the top levels of
government, and to push for its implementation.
Those working on the ground know that plenty of invasive plant populations have
increased in size, and more
infestations have gotten
started. But we have also
eradicated many highpriority populations, and
gotten others in our sights.
Our numbers are greater,
our network is deeper, and
our policies are stronger. In
the coming decade, I look
forward to solidifying these
gains and creating highly
effective systems to protect

California will receive $13 million for
invasive species programs from the
federal Farm Bill. The money will fund
programs such as parcel inspection dogs at
shipping facilities, high-risk pest detection
surveys, and a statewide survey for the
European grapevine moth. (Cal. Dept. of
Food and Ag. press release, Jan. 20, www.

gallotannin itself is harmless, it reacts with
enzymes produced by native plants and
microbes to form toxic gallic acid that
kills the native reed. Eurasian common
reed has taken over millions of acres of
wetlands in the U.S., leaving only small
patches of the North American variety.

If you see the new movie Avatar, look
carefully at the plants. UC Riverside
professor and Cal-IPC member Jodie Holt
served as a consultant for the film and its
associated video games, using her botany
expertise to help director James Cameron
provide background information about
the plants on the alien moon Pandora
(but were any invasive?). She also helped
actress Sigourney Weaver look and act
like a “real” botanist. (UC Riverside
newsroom, Nov. 24, newsroom.ucr.edu)
Are camels the newest biocontrol for
tamarisk, a.k.a. saltcedar? A rancher
in Colorado believes they might be.
Stating, “They will eat all day if given the
opportunity”, she says her 15 camels have
eaten all of the saltcedar on her ranch
and she believes they could be used to eat
the new growth that returns even after
a bush has been attacked by biocontrol
beetles. A researcher interviewed for the
article says that it would probably require
many camels to eat a significant amount
of saltcedar, similar to using goats. (High
Country News, The Goat blog, Jan. 20.,
www.hcn.org)
Invasive genetic strains of common reed
(Phragmites australis) use microbes and
soil enzymes to attack North American
populations of reed. University of
Delaware researchers discovered that
invasive reed from Eurasia produces
more of the chemical gallotannin than
the North American reed does. While
The number of invasive alien species per
country ranges from nine in Equatorial
Guinea to 222 in New Zealand. The
Global Invasive Species Programme’s new
report, “Global indicators of biological
invasion: species numbers, biodiversity
impact and policy responses”, looked at
57 countries and found that, on average,
each country has 50 non-indigenous
species which have a negative impact on
biodiversity. (www.gisp.org)
Starting in January, boaters in Oregon
will pay new fees to cover the cost
of cleaning stations and educational
campaigns for aquatic invasive species
such as hydrilla, quagga mussels, and
zebra mussels. The new law will add a $5
surcharge to motorized boat registration
every two years. Manual and paddle boats
will need $5 annual permits. Out-ofstate boaters will pay $20. The new law
was instituted because existing voluntary
campaigns against aquatic invasive species
have not had much success. (NewsReview, Nov. 3, www.nrtoday.com)

Watch out for these Red Alert weeds!
Joseph M. DiTomaso, Department of Plant Sciences, UC Davis
R
ed Alerts (or Weed Alerts) represent
potentially new species not previously
reported to be invasive in California or
species that have been here, but are now
either expanding their range at a more
rapid rate or moving into new areas of
the state. These species were all reported
by Cal-IPC members during 2009. This
year saw more reports than any previous
year and many of these species have been
on the Red Alert list of past years. With
over 50 submissions, it was not possible to
present detailed information on all these
species. As such, I have narrowed the list
down to what I felt were the most important species to discuss, but included a full
list of all species in a table (pages 6-7)
with leathery, emergent, elliptic leaves
on non-inflated stalks. The bottom of its
leaves have a diagnostic honeycomb-like
spongy tissue. The white flowers are solitary or paired and are unisexual.
In California, smooth frogbit was previously reported to have escaped cultivation as a pond ornamental in some coastal
areas, including Alameda and Riverside
counties, but the largest infestation was
in Redding. In August 2007, Pat Akers
and Mary McClanahan reported scattered patches along 10-15 miles of the San
Joaquin River in Fresno. Later in 2007 it
appeared in the Sacramento Delta and in
February 2008 another infestation near
the Kings River southeast of Fresno. It
blocks waterways by forming thick mats.
The 2009 Red Alerts include two
aquatic plants (Limnobium laevigatum
and Undaria pinnatifida), two perennial
grasses (Phalaris arundinacea and Danthonia pilosa), and three broadleaf species
(Salsola soda, Watsonia meriana, and
Romulea rosea). Most of these have not yet
been evaluated for the Cal-IPC Inventory
because we have only recently received
information on them spreading into
wildlands. If you have additional information on these species, or have seen them in
other parts of California not mentioned
here, please contact Joe DiTomaso (see email address at end of article) or Elizabeth
Brusati at edbrusati@cal-ipc.org.
Smooth frogbit or West Indian spongeplant (Limnobium laevigatum): Smooth
frogbit is a member of the Hydrocharitaceae. This is the same family as other very
invasive aquatic plants, including Hydrilla
verticillata (hydrilla) and Egeria densa
(Brazilian egeria). It is native to tropical and subtropical Central and South
America. Morphologically, smooth frogbit
is very different from hydrilla and Brazilian egeria and resembles a smaller version
of water hyacinth (Eichhornia crassipes). It
is a floating to rooted stoloniferous perennial. Smooth frogbit has a juvenile form
of partly submersed rosettes with thick
floating leaves. Juvenile rosettes gradually
develop into much larger mature clumps,
Cal-IPC News Winter 2010
The species has been placed on the
California Department of Food and
Agriculture (CDFA) Noxious Weed Qlist. This designation can give CDFA the
authority to rapidly respond to control or
eradication efforts without going through
the long process of listing a plant on the
A-list. It is not yet listed in the Cal-IPC
Invasive Plant Inventory.

Wakame or Japanese kelp (Undaria
pinnatifida): Japanese kelp is a goldenbrown kelp with flat broadly pinnatelobed or -divided fronds that can reach
over 1m in length and width. It is native
to southeast Asia and Japan where it is
used for food (sushi). Japanese kelp has
an extended period of spore production
and can release millions of motile spores
that can remain active for up to 5 hours.
It rapidly colonizes open or disturbed
substrates and floating objects and is
adapted to both warmer waters of southern California, as well as the cooler areas
in the northern part of the state. Japanese
kelp may have the potential to displace
certain native kelp species in California
coastal waters. Marina owners worry that
it will cover boat hulls, piers, and docks. It
typically inhabits the upper region of the
sublittoral zone, from the low tide mark
to about 15 m deep.
It was first discovered near Santa
Catalina Island. It soon moved to other
areas of southern California such as Santa
Barbara and as far north as Monterey,
but did not expand much for a few years
afterwards. In fact, at that time (2002),
it was included as a Cal-IPC Red Alert.
In 2009, Ted Grosholz of UC Davis and
Chela Zabin of the Smithsonian Environmental Research Center reported that it is
moving northward quickly and has been
found in several new locations in the San
Francisco Bay. Ted also indicated that it is
the most significant marine algal invasion
since Caulerpa. In addition to California,
Japanese kelp has also become invasive off
the coastal waters of France, Britain, Belgium, Spain, Italy, Argentina, Australia,
and New Zealand. It is currently listed as
a Limited species on the Cal-IPC Inventory. Visit www.serc.si.edu/labs/marine_invasions/MIRL_at_RTC/undaria.aspx for
factsheets and instructions for reporting
suspected sightings of Undaria.
canarygrass have been made, but these are
from populations on the east coast.
Little is actually known about its
genetics in California. While the native
biotypes are an important component of
the ecosystem and provide food for seedeating birds, the non-native forms can
displace other native plants that are more
desirable in those particular habitats. This
is the case in many other northern states,
such as Oregon, Washington, Idaho,
Montana, and Wyoming. In Washington,
reed canarygrass is a state-listed noxious
weed. Because of the confusion related to
what is native or from European origin,
Cal-IPC has not, to date, listed reed canarygrass on its current inventory. Athena
Demetry at Sequoia-Kings Canyon National Parks reports that it is spreading in
the Sierra Nevada, suggesting that perhaps
these infestations are non-native.
Glasswort (Salsola soda): Glasswort is
a member of the Chenopodiaceae and a
close relative of Russian thistle (tumbleweed). It is native to southern Europe
and is very distinctive because of its fleshy
succulent nature and adaptation to saline
environments. Unlike the other Russian
thistles, glasswort foliage remains fleshy
in fruit. Glasswort inhabits mudflats and
saltmarshes in the San Francisco Bay
region. Populations in the San Francisco
Bay seemed to be fairly stable in the past
few years, but this year have dramatically
expanded in the Suisun Marsh area. Sarah
Estrella of the Cal. Dept. of Fish and
Game reported that a small infestation
expanded to cover over two acres and was
displacing the native Salicornia (pickleweed) species. The species has not yet
been evaluated for the Cal-IPC Inventory.
Hairy wallabygrass, hairy oatgrass
(Danthonia pilosa = Rytidosperma
pilosum): Hairy oatgrass is a perennial
bunchgrass native to Australia. The Jepson
Manual lists it as being found in disturbed, open sites, meadows, and coniferous forests in the north and central Coast
Ranges, Klamath Range and the San Francisco Bay Area. Both Peter Warner and
Tim Hyland reported that it is becoming
a dominant species in the coastal terrace
prairie and upland grassland of many
northern California coastal counties. In
these areas, it appears to be outcompeting
native California oatgrass (Danthonia californica). Although relatively widespread,
this species may be increasing its rate of
spread. It has not yet been evaluated for
inclusion on the Cal-IPC Inventory.
Reed canarygrass (Phalaris arundinacea): Reed canarygrass is a coarse
perennial to 1.5 m tall, with creeping
rhizomes. It is considered an obligate
wetland species inhabiting wet sites along
streams. Although it is considered native
to California, there are European biotypes
that have been introduced into the United
States and have likely invaded California,
perhaps even hybridizing with the native
forms. Comparisons of the hybridization
of European and North American reed

Rosy sandcrocus (Romulea rosea var.
australis): Rosy sandcrocus is another
member of the iris family. It is a small
pink flowered perennial ornamental that
has escaped cultivation. Rosy sandcrocus
is native to South Africa and was typically
found on disturbed dry sandy or often
hard-packed soils in the San Francisco
Bay Area and other sites along the central
and north coast. Peter Warner reports that
while it appeared for years to be restricted
to disturbed areas and roads along the

Watsonia (Watsonia meriana =Watsonia bulbillifera): Watsonia is a member
of the iris family (Iridaceae) and is native
to South Africa. It is a common perennial ornamental species that reproduces
by bulblets and corms at the base stem.
The species has been reported to be locally abundant in some areas along the
north coast, particularly on roadsides,
open fields and waste areas, however, Peter
Warner reports that it is now spreading
both south from Sonoma County and
north from Mendocino County. Smaller
patches are now coalescing and spreading
into marshes, woodlands, and grasslands
adjacent to roadsides. Watsonia is currently listed as a Limited plant in the Cal-IPC
Invasive Plant Inventory.

National Park Service releases early detection protocol
Andrea Williams, Marin Municipal Water District
Andrea Williams previously worked for the
National Park Service and is the co-founder
of the Bay Area Early Detection Network.
W
e’ve heard the tenet before: early
detection and rapid response is,
aside from prevention, the most cost-effective way to deal with invasive species.
In plans ranging from individual land
units, to local Weed Management Areas
(WMAs), to the state of California, national agencies, and national and international interagency panels, they say, “Go
forth and do early detection”. But what
does that actually translate to, and how do
we “do” early detection? A recently published protocol from the National Park
Service’s San Francisco Bay Area Inventory
and Monitoring Network (SFAN) answers
these questions.
The SFAN encompasses diverse national park units, including Golden Gate
National Recreation Area, Point Reyes
National Seashore, Pinnacles National
Monument, and John Muir National
Historic Site. The SFAN is one of 32 Inventory and Monitoring (I&M) Networks

The list of target species for each park
was based on current knowledge and
rankings, summing recognized invasiveness and biological ease of control and
stratifying into priorities by feasibility of
control based on species’ infested acreage
in the park. Species listed by Cal-IPC,
the Cal. Dept. of Food and Agriculture (CDFA), The Nature Conservancy
(TNC), and local WMAs received varying
numbers of points for invasiveness, as did
unlisted species which shared invasive
characteristics with a listed congener.
Based on best available knowledge, species
also received points for altering ecosystems—affecting a system change, not
just crowding out other plants—and for
endangering rare plants in SFAN parks.

nvasive plants. We love to hate them.
And, many of us derive pleasure from
pulling, whacking, spraying, burning,
or at least cursing at them. But, an often
forgotten prerequisite for successful weed
control is the accurate identification of the
undesirable plant. Identification is important not only when deciding whether or
not you have a problem plant, but also in
the selection of an herbicide, since most
herbicides work on some plant families
but not others. Early detection programs
depend on the accurate identification of
known and potential plant invaders. Too
often we give up when we have doubt
about the true identity of a potential
invasive plant, or even worse, we proceed
to control a plant that is not actually the
problem plant we thought it was.
Don’t despair! Free, no-experiencenecessary plant identification workshops
are provided by Ceanothus: California
Field Botanist Association throughout the
Sacramento Valley at locations and times
listed on our website (www.ceanothus.
org). All types of plant enthusiasts, from
backyard gardeners to weed workers to
professional botanists, are invited to attend the workshops. Everyone is encouraged to bring plants they are interested in
identifying, a Jepson Manual, and
plant dissection tools, if you’ve got
them. The only requirement is that
you have fun!
The supportive group environment at Ceanothus workshops
was first envisioned two years ago
by consulting botanists Melissa
Hostler and Erin Gottschalk Fisher.
Since its inception, Ceanothus has
welcomed consulting botanists
Debra Sykes and Michael Bower

Conference Reports
Climate change, biofuels, the green economy, & weeds!
A
s more states form Weed Management Areas and Invasive Species
Councils (including California!), we are
entering an era of increased awareness
of the linkages between invasive species
and economic issues. Even the Wall Street
Journal recognized the economic impact
of invasive species in a recent article (Jan.
15). National Invasive Species Awareness Week, formerly known
as National Invasive Weeds
Awareness Week, brought 130
participants from 30 states to
Washington, D.C. from Jan.
11-14.
Attendees learned about
invasive species programs at
Defenders of Wildlife, the Lady Bird
Johnson Wildflower Center (Texas), Student Conservation Association, and other
organizations, agencies and universities.
Perhaps the most provocative title on the
agenda was “Johnny Appleseed was a Bioterrorist” by Dr. Ernest Delfosse of Michigan State University. California Secretary
of Food and Agriculture A.G. Kawamura
also spoke at the event, saying “Invasive
species affect all walks of life — from the
environment to our food supply to the
health of our families and pets.”
NISAW focused on three topics:
climate change, the “green economy”, and
biofuels. Below we have excerpted points
from position papers that were distributed
to congressional staff by NISAW attendees. To read the full position papers with
recommendations for action by the federal
government, visit www.nisaw.org/.
Climate Change
Climate change and biological invasions are dynamic, interconnected, and
interdependent phenomena that alter
ecosystem services. Ecosystem goods and
services, in turn, impact agriculture and
food security, water supplies, natural
resources, wildlife, recreation, and public
health and safety nationwide.
Climate changes confound predictive
biological models and, more importantly,
the policy decisions based on the mod-
10

els. As climate conditions change, novel
ecosystems may be filled with a new mix
of native and non-native species. A current assessment of the distribution and
environmental requirements of invasive
species across North America with respect
to climate trends is necessary to determine
effective ecosystem
management policies.
assistance, policy and regulation, control,
eradication, and restoration. In addition
to jobs created specifically to address
invasive species, the technical demands of
invasive species prevention and management expand job opportunities across
a wide variety of sectors (e.g., software
development for mapping and modeling,
development and testing of tools for integrated pest management).
Biofuels
We call on Congress to build incentives into climate change legislation that
require the use of non-invasive plant species for activities such as carbon sequestration, biofuels, post-wildfire land rehabilitation, land and water adaptation, and
wildlife habitat security so new legislation
supports long-term ecosystem health.
The Green Economy
Invasive species are intricately linked
to the economy. Trade, travel, and transport facilitate their spread. Invasive species
management requires extensive human
and financial resources.
The impacts of invasive species can
substantially undermine economic growth
and sustainable development. Invasive
species prevention and management can
foster the “green economy” through green
collar job creation and social development
programs. On the other hand, if invasive
species are not addressed as a matter of
urgency, their spread and consequent impacts will substantially undermine green
economic growth, including our capacity
for renewable energy development and
expansion.
The prevention and management
of invasive species requires substantial
human resources across a wide range of
expertise, including inspection, taxonomic
identification, research, monitoring,
education and communication, technical
To provide alternatives to
petroleum-based energy, the
U.S. government has mandated
a greater proportion of plantbased biofuels be integrated
into its energy portfolio. However, certain
plant species being proposed for biofuel
production in the U.S. are invasive species or are likely to escape cultivation and
become invasive.
To minimize the risk of biofuel crop
escape into the surrounding environment,
the U.S. government needs to employ and
promote ecological studies and scientific
models that characterize the invasion
risk of each biofuel species or cultivar
(as appropriate) within a target region
and identify ecosystems most susceptible to invasion. Information generated
from biofuel crop ecological studies, risk
analyses, bioeconomic and climate match
modeling, and other methods can guide
the government’s risk mitigation plans…
Federal agencies can take strategic steps
at appropriate points within research and
development, crop production, harvest
and transportation, conversion and refinery practices, and/or regulatory action to
minimize the risk of biofuel crops becoming invasive.

11th Annual Central California Invasive Weed Symposium
The theme of this year’s Central California Invasive Weed Symposium at the
Santa Cruz County Fairgrounds was “Fire,
Water, Action!” The new fairground
venue was refreshing and highlights the
new organizing partnership between the
Monterey County WMA and the budding
Santa Cruz WMA.
Presentations ranged from discussing
balancing fire hazard and weed invasion,
to the need for the weed community to
move beyond using only RoundUp when
using a chemical control methods, to leveraging the use of large equipment to get
lots of work done, to the cost effectiveness
of small-scale fennel control, and to the
opportunity to partner with mosquito
abatement professionals.
Tim Hyland, Cal. Dept. of Parks and
Recreation, presented on his (and his
colleagues) successful efforts to control
European beachgrass (Ammophila arenaria) using innovative integrative techniques
that are more financially viable than previously described techniques.
Bob Case hosted the popular “Jeopardy Gameshow: Don’t Laugh about Laws
& Regs” developed by David Chang for
the 2009 Cal-IPC Symposium, complete
with audience members as contestants.
This led to possibly the most laughter at
any Laws & Regs session in the history of
the Cal. Dept. of Pesticide Regulation.
Following an amazing organic lunch,
attendees had the chance to discuss poster
topics and interact with each other.

without the “Tool Tailgate”? This year
mechanical masticators, biological masti-
cators (goats), jeeps modified for herbicide
application, native nursery stock, a hydro
obliterator demonstration that really obliterated, and more provided the attendees
with demonstrations of inventive and
effective tools for better weed control.
Following the symposium, field trip
participants were treated to a tour of the
Watsonville Slough, High Ground Organics and Harkins Slough. High Ground
Organics has been committed to restoring upland portion of the slough from
degraded land to native habitat, including the Santa Cruz tarplant (Holocarpha
macradenia), which is on the verge of
extinction.
This symposium continues to bring
land managers, contractors, restoration
professionals and volunteers together to
share their successes, struggles, and pioneering weed control strategies. Thanks
to the organizers, presenters, and attendees for keeping the flame alive.
The 12th Annual CCIWS is tentatively scheduled for Friday, Nov. 12, 2010.

The keynote speaker, Bruce Baldwin of
UC Berkeley, spoke on the abundance
of cryptic diversity, but some of the
other presenters discussed not-so-cryptic
diversity, including a newly described,
six-foot-tall plant living clonally on the
side of the road in northern California
— Sidalcea gigantea.

Sacramento
Valley Regional
WMA Meeting
Gina Darin, CA Dept. of Water Resources
The Sacramento Weed Management
Area (WMA) hosted the first-of-its-kind,
regional WMA meeting in November,
2009. Over 40 attendees participated in
the meeting representing 15 neighboring counties and included representatives
from state and local agencies, utilities,
NGOs and universities.
The Sacramento County Agricultural
Commissioner congratulated the group
on being the local contingent of a nationwide effort to address issues caused by
invasive plants.
Programs affecting California’s WMAs
were discussed, including the American
Recovery and Reinvestment Act (aka
federal stimulus funding); Cal-IPC’s statewide mapping projects; the newly formed
Bay Area Early Detection Network
(BAEDN); continuing work with the
horticulture industry by the PlantRight
campaign; and the state’s newly-formed
interagency invasive species council.

Research on targeted grazing for weed
management was presented by Morgan
Doran of UC Cooperative Extension, and
Dale Woods of the Cal. Dept. of Food &
Agriculture presented the latest news on
biological control projects.
During the afternoon session WMAs
gave updates on current and scheduled
projects. A Pacific Gas & Electic representative announced that they have begun
implementing a comprehensive weed
management program. During the open
forum, attendees shared control tips and
tools, a stinkwort brochure, how to better
communicate with Caltrans, and an effective letter to property owners requesting
access to their land.
By focusing on regional issues and providing a venue for neighbors to share ideas
the meeting was a great success. The leaders of the Sacramento WMA hope that
this meeting will inspire other counties to
host regional meetings in the future.
