1. Invasive species management workshop (Maryland, USA)
From: Barry Rice (bamrice(at)ucdavis.edu)
I have heard about a one-day workshop for invasive plant management 24
October, at Fort Detrick in Frederick, Maryland. The focus is on optimal
control methodologies. The workshop is limited to 40 participants, and if
it fills up a second workshop will be held on 25 October. If you are
interested, contact the organizer (Steve Manning) at
stevemanning(at)pop.mindspring.com, 615-385-4319.

2. Houttuynia cordata (Global)
From: Barry Rice (bamrice(at)ucdavis.edu)
Betsy Lyman (TNC, Pennsylvania; blyman(at)tnc.org) emailed in concerns about
Houttuynia cordata 'Chameleon'. This plant is commonly called the
"chameleon plant". Betsy has heard that this plant has invasive properties
in her area, and is wondering if this is something she should be concerned
with. Has anyone seen this plant escaping in a wildland setting?

3. Planting Natives after knapweed Removal (New York, USA)
From: Maura Sullivan (mauras(at)tnc.org)
I am working on a 144 acre preserve in New York and I'm considering
pulling spotted knapweed and then planting some rare, native herbaceous
species that we have propagated from seed. Success will depend greatly on
the habitat requirements of the plant species (Pycnanthemum torrei and
Liatris borealis), but will they be at a disadvantage planted in soil
degraded by spotted knapweed (i.e. increased soil erosion associated with
knapweed populations and perhaps lingering cnicin?)?
I would like to be able to remove the knapweed completely and then tackle
the resulting soil disturbance by replanting with native species, but I
doubt it will be that simple. In any case, we will plant the rare guys in
a few different locations and monitor the success of the plantings as well
as the eradication of the knapweed. Any input will be appreciated!

4. How to get weed-free top soil (New York, USA)
From: Michelle Brown (mlbrown32(at)hotmail.com)
I am working for The Nature Conservancy on a project at Sam's Point along
the Shawangunk Ridge. One of our goals is to reduce the size of the
parking lot, and restore it with native vegetation. We need to import
topsoil for planting. I am looking for experiences (successes and
failures) people have had concerning sterilization of soil and equipment
to reduce the effect of invasives.
Is sterilization recommended over other means of
controlling invasives, such as pre-emergent herbicides, black plastic,
appreciated.

5. Seeking information about YOU (Global)
From: Lori Quillen (lquillen(at)tnc.org)
The Invasive Plant Council of New York State (IPC NYS) is compiling a
database on people who are working on invasive species. This will be a
feature on the new IPC website at- www.ipcnys.org
If you, or anyone you know, is working on such projects, please contact
me (lquillen(at)tnc.org, 518-271-0346) with the information listed below.
1) A name and address. E-mail and phone #'s are optional, but they do
help make communication easier;
2) The species you are working on;
3) The size of the land you are managing;
4) The general habitat type.
You could also provide information on the management success and obstacles
you are having. This will allow others to reap the benefits of your
innovations, and it will connect you with people who might have
constructive advice for projects that are stalled or less than effective.
I would also be glad to provide a link to your organization's website.
This database should help all of us, and your input is appreciated! Feel
free to spread this e-mail around to other people! THANKS!
