1. Listserve address change (Global, Planet Earth)
From: Barry Rice (bamrice(at)ucdavis.edu)
Greetings loyal listserve readers,
If you wish to post notices to this listserve (and we hope you do!), please
email your notices directly to me at bamrice(at)ucdavis.edu and I will make
sure they are posted properly. If you mail your listserve queries directly
to the tncinvasives(at)ucdavis.edu address, it is likely to be misclassified by
the listserve software as spam and be deleted. So please, send all your
interesting postings for the invasives species listserve to me directly.
---------------------------------------
2. Follow-up on Silphium perfoliatum (New York, USA)
From: Barry Rice (bamrice(at)ucdavis.edu)
In Invasive Species Listserve Digest #130, Steven Flint asked about Silphium
perfoliatum (Indian cup-plant). Thanks go out to Marilyn Jordan and others
who verified that this species is not native to New York. Marilyn (who was
fastest at her keyboard to respond) provided a useful reference: Mitchell,
R. S. and G. C. Tucker. 1997. Revised Checklist of New York State Plants.
Bulletin No. 490, New York State Museum, Albany, New York 12230.
---------------------------------------
3. Freeze control? (Florida, USA)
From: Doria Gordon (dgordon(at)tnc.org)
I am very interested in whether anyone has done research on how to apply
freezing temperatures in the contol of invasive sub-tropical plants. Not
boiling them, but freezing them! Has anyone heard or read about this being
tried?
---------------------------------------
4. Sampling strategies for early detection systems (Global, Planet Earth)
From: Melissa Trader (mtrader(at)usgs.gov)
I am working on a review of methodologies for early detection of invasive
species and I came across The Nature Conservancy's Weed Watchers Program;
what a wonderful program it is!
I am looking for someone who could provide more in depth information on
sampling strategies and designs promoting early detection of invasives and
results of these methods, e.g. number of plants/plant populations found this
way and time or resources used.
Any information that you could provide would be helpful.

5. Second Aridland-Invasives Workshop! (Western states, USA)
From: Mandy Tu (imtu(at)tnc.org)
The second workshop of the "Western North America Aridlands-Invasives
Network" will be held this January 19-21, at Irvine Ranch, California. In
this 3-workshop series focused on invasive species prevention and management
in the arid west, we work with participants through the adaptive management
process. New participants and projects sites are welcome! In this second
workshop, we will start by reviewing the quantifiable objectives that you
set last time for abating the invasive species threat at your project site,
then we will focus the rest of the workshop on how to assess invasive
species threats (to determine if and when action is necessary) and how to
monitor the success of your actions.
Questions/topics that will be discussed include:
- Can small scale successes translate into large landscape scale success?
- How can we adequately monitor both the invasive species threat, and our
success at preventing and abating those threats?
- How do you set monitoring objectives?
- What are some sampling designs that can be used at the landscape scale?
- Selecting adequate indicators
- How to analyze and interpret your monitoring data
CONFIRM your attendance by December 15, 2004!!

6. Adirondack Park Invasive Plant Program Newsletter (New York, USA)
From: Hilary Oles (holes(at)tnc.org)
--Hilary sent us a link so we could peek at the new newsletter that the
Adirondack Park Invasive Plant Program created. See it yourself at:
http://www.adkinvasives.com/documents/ROOTSNov04_001.pdf
We think this newsletter, and in fact the entire invasive plant prevention
and control program Hilary is working on, is just the kind of effort that
any state and country would be proud of. You go, Hilary!

7. Invasive Plant Network Coordinator Job (Global, Planet Earth)

8. Update on saltcedar biocontrol (Western states, USA)
From: Barry Rice (bamrice(at)ucdavis.edu)
Earlier this week I had the pleasure of visiting a biocontrol release site
in Nevada, where Ray Carruthers (USDA-ARS) is studying the impact of a
saltcedar (Tamarix spp.) biocontrol.
Very shortly, some of the early results are as follows:
---The biocontrol (a beetle, Diorhabda elongata) is surviving.
---The biocontrol is expanding in numbers, with 30x population
increases/generation!
---The beetles are getting excellent (near 100%) defoliation, and are
spreading well.
---While surviving the initial defoliations, the saltcedar has something to
worry about!
Some nice web sites on this work:

Very promising work, Ray!
