Horticulture/Nursery Professions Liaison (Global, Planet Earth) 3. TNC project profiles on line--you could be next! (Global, Planet Earth) 4. Gypsy moth publication on line (North America) 5.

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! http://tncinvasives.ucdavis.edu (top of the page) ***The Weed Control Methods Handbook chapter-section on Imazapyr has been updated: http://tncinvasives.ucdavis.edu/handbook.html **More meeting updates. See: http://tncinvasives.ucdavis.edu/meetings.html --------------------------------------- 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: http://nature.org/cgi-bin/zope.pcgi/careers/natureorg/20040706153854.html 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 bamrice(at)ucdavis.edu. 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 them. --------------------------------------- 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: http://tncinvasives.ucdavis.edu/projects.html 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: http://www.natureserve.org/library/gypsyMothReport.pdf --------------------------------------- 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. http://tame.ifas.ufl.edu/media/docs/IPRLOffshoots-0607-04.pdf --------------------------------------- 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: http://tncinvasives.ucdavis.edu/tools/wand.html 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 herbicides? --------------------------------------- 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): http://www.fedgrants.gov/Applicants/DOC/NOAA/GMC/11417Invasive071404/listing .html Brief info: --Pre-proposals due August 27, 2004; proposals due Nov 16 --NGOs are eligible --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. --2:1 match required (Fed$:non-Fed $) --------------------------------------- 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: http://webapps.lib.uconn.edu/ipane/browsing.cfm?descriptionid=44#common 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. |
