News from the Global Invasive Species Team
1. Invasipedia, a new TNC wiki! (Global, Planet Earth)
From: Barry Rice (brice(at)tnc.org)
There is little doubt that the Global Invasive Species Team web site, now in its 12th year, is chock-full of useful information. However, some of its resources are rather old. What to do?
To keep the site content relevent and fresh, we have now launched a wiki that can be edited by anyone! Now, all invasive species practitioners can contribute their vast knowledge and experience to our current set of documents, and add new content on how to best manage invasive species. While Invasipedia is currently restricted to plants, if the users wish to expand its scope---well, they can! For those who are frightened that an open wiki is going to be a recipe for disaster, rest assured that we are monitoring this site and will watch for pointless vandalism. We are confident that this exciting project will be a place for users to launch their best management practices.
To help jump start this process, we have preloaded the wiki with GIST treatments for about 30 species. You can start your wiki-work by reviewing these treatments, and if you see something that could be added to, please do so. When you get confident, you can start adding treatment for new species! Some resources to help you get used to Invasipedia are given below.
Have fun!!!!

2. Goodbye tncweeds web site; hello tncinvasives (Global, Planet Earth)
From: Barry Rice (brice(at)tnc.org)
Webmasters note: our web site url has changed from http://tncweeds.ucdavis.edu to http://tncinvasives.ucdavis.edu. All deeper url references are unchanged other than the top-level url change; for example the Gallery of Pests url has changed from http://tncweeds.ucdavis.edu/gallery.html to http://tncinvasives.ucdavis.edu/gallery.html, etc.
In fact, you can simply refer to our front page using the much simpler:

Nice, huh?

New Documents and Resources
3. New brochure on invasives in Maryland (Maryland, USA)
From: Mary Travaglini (mtravaglini(at)tnc.org)
The Maryland chapter and partners have created a new brochure called "Terrestrial Invasive Plants of the Potomac River Watershed". This includes information on invasive plants of our area, control measures, and also a wallet-sized foldable insert people can easily carry with them to nurseries to help them shop for noninvasive alternatives.
See these resources on the Global Invasive Species Team web site!
To learn more about our efforts, visit our chapter's invasives page!

4. Oregon booklet on-line (Oregon, USA)
From: Barry Rice (brice(at)tnc.org)
Oy! In case you have somehow overlooked this latest addition from the Oregon chapter and a number of fine partners, take some time to review the statewide public information campaign, "Stop the Invasion". In addition to a documentary on public television ("The Silent Invasion"), volunteer opportunities, and fact sheets, the coalition has produced an extraordinary 54-page booklet on invasives and GardenSmart alternatives!

5. Twig beetle and black walnut disease (Rocky Mountains, USA)
From: Barry Rice (brice(at)tnc.org)
If you are unfamiliar with the twig beetle and its associated black walnut disease, there is no time better than now to rectify this gap in your knowledge. Read our new profile of these two organisms on the Global Invasive Species Team web site.

6. Bibliography of biodiversity impacts needed (Colorado, USA)
From: Mark Gershman (gershmanm(at)bouldercolorado.gov)
I am finishing up a CAP-esque project for Boulder's Open Space grasslands and an offhand comment about the level of documentation of the "weed problem" pointed us towards Levin et al. (2003). I was wondering if any of you folks maintain a database of studies like Lippincot (2000) and Caraco & Cole (2002). If you have or are aware of a bibliography of biodiversity impacts, I would be interested in finding out more.

7. Neem tree invasive? (Global, Planet Earth)
From: John de Freitas ( freitasj(at)cura.net)
Are there any reports of invasiveness of the neem tree (Azadirachta indica) in the Americas or the Caribbean?

8. Recent TNC invasives projects (Global, Planet Earth)
From: Barry Rice (brice(at)tnc.org)
Culled from the most recent issue of Nature Conservancy magazine (Winter 2008): Nevada
The Conservancy's efforts to remove invasive tamarisk along the Muddy River near Las Vegas appear to be improving habitat for breeding birds. Volunteers surveyed the river and discovered many bird species--including phainopeplas, Abert's towhees and lazuli buntings--breeding in the river corridor. Tamarisk poses great threats to the river and its banks, which are home to four native fish species, seven rare invertebrates and many rare birds. More about the Muddy River
South Dakota
The Conservancy and South Dakota State University, through the Prairie Coteau Habitat Partnership, began monitoring the effects of prescribed fire on habitat and forage quality in South Dakota's Prairie Coteau region. The information will be shared with landowners to demonstrate that keeping grasslands healthy through the use of prescribed fire can also have a positive economic effect by reducing expenses for weed control and improving cattle health. Most of the region's grasslands are privately owned, making landowner involvement in conservation vital.

Utah
This summer, the Conservnacy launched the first phase of a large-scale, 10-year effort to restore habitat at the Scott M. Matheson Wetlands Preserve. The preserve is part of the largest wetland ecosystem in Utah's Colorado River corridor and is home to hundreds of species of migratory birds, amphibians and aquatic mammals. The Conservancy began by removing roughly 70 acres of tamarisk and, in subsequent years, will remove dikes and invasive species, conduct controlled burns, and replant native vegetation.
