Global Invasive Species Team listserve digest #090 Fri Jul 27 2001 - 14:58:58 PDT --CONTENTS-- 1. Invasive species management workshop (Maryland, USA) 2. Houttuynia cordata (Global) 3. Planting Natives after knapweed Removal (New York, USA) 4. How to get weed-free top soil (New York, USA) 5. Seeking information about YOU (Global) --------------------------------------- 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! |
