1. Virus warnings, minor web site additions (Global, Planet Earth)
From: Barry Rice (bamrice(at)ucdavis.edu)

As many of the listserve readers noticed, earlier this week an electronic
worm (W32.Beagle.AB(at)mm) found its way into our listserve by forging an
appropriate address, and sent itself out as an attachment. I hope you
weren't duped--it did not come from our machines.

Recent minor updates to the TNC Invasives web site include:

***The addition of "Best Management Practices" guidelines for several common
weeds in the Pacific Northwest, including Himalayan blackberry (Rubus
armeniacus), Scotch broom (Cytisus scoparius), English ivy (Hedera helix),
and the knotweeds (Polygonum spp.)! Very useful stuff!

***The Weed Control Methods Handbook chapter-section on Imazapyr has been

2. Horticulture/Nursery Professions Liaison (Global, Planet Earth)
From: John Randall (jarandall(at)ucdavis.edu)

TNC in cooperation with the Missouri Botanical Garden (MOBot) has just
posted a job announcement for a "Horticulture and Nursery Professions
Liaison". The successful candidate will be based at MOBot in St. Louis and
will work with interested nurseries, landscape architecture firms and
botanical gardens around the US to implement and test practices designed to
minimize invasions of horticultural plants.

The announcement is available on TNC's internet site (http://nature.org) and
may be reached directly at:

Applications should be submitted to John Randall and Barry Rice, TNC
Invasive Species Initiative, 124 Robbins Hall, Weed Science Program,
University of California, Davis, CA 95616, USA. Electronic submissions are
welcome and should be submitted to BOTH jarandall(at)ucdavis.edu and

The application deadline is July 30, 2004.

We are excited about the promise of this cooperative effort with the nursery
industry, landscape architects and botanical gardens and are looking for
candidates with expertise in and passion conservation, horticulture and
landscape professions. If that describes you we encourage you to apply! If
you know someone who might fit this position, please forward this message to


3. TNC project profiles on line--you could be next! (Global, Planet Earth)
From: Barry Rice (bamrice(at)ucdavis.edu)

The Invasive Species Initiative staff has started web-postings that profile
excellent ideas and projects related to invasive species management,
control, planning, outreach, etc. Our hope is that this site will help give
those people working on great projects a little more well-deserved
publicity. Also, it will be a fine place for people---who might be looking
for ideas or inspiration---to go and see what has already been done, so they
do not have to recreate the wheel.

We already have profiles on line for programs in a number of states,
including California, Connecticut, Florida, Georgia, Maryland,
Massachusetts, Montana, New York, Oregon, and Brazil. See what is already in
place at:

If you're working on some neat invasive species project, contact me and I'll
help you get it profiled on our site.

You may wonder how this might differ from the state profiles at nature.org.
Our profiles tend to contain more of the dirty details on how projects are
actually implemented. That way, other operating units can replicate the
successes and avoid the failures.


4. Gypsy moth publication on line (North America)
From: Tunyalee Martin (tamorisawa(at)ucdavis.edu)

A new publication is available online about the impacts of gypsy moth
control on biodiversity. Gypsy moth was introduced to North America in 1869
and can become a pest causing defoliation of forest trees. Actions to
reduce moth numbers included chemical sprays during the 1950s through the
1970s and the release of biological control agents, both which are thought
to have negative non-target effects on native moths. Schweitzer's
publication discusses the historical and current impacts of chemical
pesticides, biological pesticides such as Bacillus thuringiensis var.
kurstaki (Btk), and insect growth regulators. If you would like to learn
more about gypsy moth control to best determine your management decisions
then check out:


5. Melaleuca update (Florida, USA)
From: John Scoles (scolesj(at)bellsouth.net)

The US Department of Agriculture's Invasive Plant Research
Laboratory(IPRL)in Fort Lauderdale, Florida is actively working on many
projects to control invasive plants in the U.S. You are invited to read the
June/July report on current activities at the IPRL; follow the link below to
the TAME Melaleuca project internet site.



6. Herbicide wand (North America)
From: Paul Still (stillpe(at)aol.com)

I am writing a USDA SBIR grant to develop an herbicide wand similar to the
one designed by Jack McGowan-Stinski, and described on the TNC-invasive
Species Initiative web site at:

My version does not have the ball valve and is attacher to the lopper handle
with pipe clamps. This let the user cut a stem and then apply herbicide
while holding onto the lopper.
Do anyone have data on the effectiveness of the wand on the TNC-invasive
Species Initiative web site? What plants have you treated and with what


7. Funding for invasives in freshwater, coastal, marine (Nationwide, USA)
From: Elizabeth Sklad (esklad(at)tnc.org)

For anyone interested in applying for funding to work on aquatic invasive
species in Great Lakes, coastal, or marine systems, follow this link (you
may have to cut/paste it if it is multiple lines long):

Brief info:
--Pre-proposals due August 27, 2004; proposals due Nov 16 --NGOs are
--Description: The National Sea Grant College Program seeks to fund research
and outreach projects addressing the introduction and spread of aquatic
invasive species. The goal of the program is to discover and develop
information and tools that can lead to the prevention, monitoring and
control of aquatic invasive species threatening United States coastal,
oceanic and Great Lakes communities, resources and ecosystems.

8. Detection alert: Cardamine impatiens (Nationwide, USA)
From: Bill Jacobs (bjacobs(at)tnc.org)

Cardamine impatiens (narrowleaf bittercress) has been identified at five
locations on Long Island. This is one of the few invasive plants on the
LIWMA high-priority early detection and eradication list.

Cardamine impatiens is an herbaceous annual or biennial that can grow to be
2' (0.6m) in height. Cardamine impatiens can form dense stands in woodland
habitats and out-compete native species. It is easily dispersed due to its
seed-shooting ability. The seeds may be ripe or nearly ripe, so we need to
get to them quickly and destroy them. Photographs and more information about
this plant can be seen at:

Cardamine impatiens can grow in shady woods with dappled shade, and along
shady edges of forest. They also do well in areas that have moist soil. In
at least one site it was found growing with garlic mustard.

Cardamine impatiens has been spreading throughout the Northeast and should
be identified and controlled (eradicated, if possible) on Long Island.

We do not know how widespread the invasion on LI is. Please report
infestations to me or Kathy Schwager (kschwager(at)tnc.org).


9. Help needed on English elm (Washington, USA)
From: Sarah Reichard (reichard(at)u.washington.edu)

I am looking for control methods for Ulmus procera, the English elm. Because
it vigorously sprouts from the roots and is locally widespread, I suspect it
will need to be treated with herbicides. If anyone has had success
controlling any elms, I would like to know which herbicides and application
methods are most successful.
