Monitoring methods sought (New Hampshire) 4. Are goats effective? (Oregon) 5. BLM-TNC Northwest Weeds Partnership (Idaho/Oregon/Washington) 6. Executive Director sought for Invasive Plant Council (New York) 7. Literature reviews (Global) --------------------------------------- 1. Grazing goats on Dipsacus (Oregon) From: Ray Guse (rguse(at)tnc.org) Does anyone know how grazing may affect common teasel (Dipsacus)? We are currently experimenting with mowing after plants bolt, but before flowering is completed. This requires a great deal of effort from staff and volunteers and only covers a small percentage of the area. --------------------------------------- 2. Info on Asphodelus fistulosas needed (California) From: Mike Kelly (mkellysd(at)aol.com) Has anyone had luck killing Asphodelus fistulosas? Glyphosate seems not to be very effective, or our timing is off, or something. Is there a good web site for info on the biology and ecology of this plant? --------------------------------------- 3. Monitoring methods sought (New Hampshire) From: Krista Helmboldt (khelmboldt(at)tnc.org) Are there any good, simple, efficient protocols for monitoring the following: --Baseline and post-release monitoring to evaluate effectiveness of releasing biocontrol beetles for Lythrum salicaria. --Baseline and post-control monitoring to evaluate effectiveness of removal of Vincetoxicum nigrum. --Baseline and post-control monitoring for Euphorbia cyparissias. --------------------------------------- 4. Are goats effective? (Oregon) From: Karen Allen (kxallen(at)aol.com) I am trying to find references of those who have tried goats on spotted knapweed (Centaurea biebersteinii, a.k.a. Centaurea maculosa) or other weeds and have monitored and documented their success (or lack thereof). Any ideas?? --------------------------------------- 5. BLM-TNC Northwest Weeds Partnership (Idaho/Oregon/Washington) From: Alan Holt (aholt(at)tnc.org) For the past year, the BLM's Idaho and Oregon/Washington offices and The Nature Conservancy have been cost-sharing a project to accelerate weed management in the Northwest through Cooperative Weed Management Areas (CWMAs) and county weed programs. A Conservation Impact consultant (Will Murray) was contracted to assist the Washington State Noxious Weed Control Board, and Cooperative Weed Management Areas in the Tri-State (Hell's Canyon), Tri-County (eastern Oregon), and Warner Basin (eastern Oregon) areas in assessing their progress and needs through a "group interview" process. The main findings of this analysis are: * The weed management area concept is successful in reframing the issue of weed management toward a collaborative, cross-boundary effort. * The coordinator is the single most important factor in success of the operations of the weed management area. * Weed management areas have faithfully followed the strategy spelled out in the manual Guidelines for Cooperative Management of Noxious Weeds: Development of Weed Management Areas (Available at the USDA web site by downloading the self-extracting file stored at [http://www.team.ars.usda.gov/weeds.exe]. Run this file to unpack its 25 pdf files that can be read using Adobe Acrobat. These contain the Preface, 9 Sections and 15 Appendices for the Guidelines). * All three weed management areas studied are below a threshold of investment that will enable them to reach their goals. * At present, the WMAs are strong on cooperation and effective use of available funds, but short on clear, long-term goals and estimates of the resources they will need to succeed. * Weed managers need training or professional marketing support to enable them to craft effective public outreach/education programs. Current efforts do not target key audiences or provide measurable objectives. * Information management and database/mapping systems are inadequate. These need to be standardized, populated and maintained as a cornerstone of successful weed management. BLM and TNC in the Northwest are now working on several projects to address these needs, including joint refinement with the Idaho Department of Agriculture of a database for tracking and sharing weed management information, shared training, and public education. For information or to collaborate, contact: Alan Holt, TNC Director of Conservation Programs, NW and HI Division, (206) 343-4344, or email: aholt(at)tnc.org. or Bob Bolton, OR-WA Weed Coordinator, BLM, 541-947-6114, or email: Robert_Bolton(at)or.blm.gov A copy of the CWMA study can be obtained from the News and Notes section of this web site. --------------------------------------- 6. Executive Director sought for Invasive Plant Council (New York) From: Neil Gifford (ngifford(at)tnc.org) The Invasive Plant Council of New York State (IPC NYS) is a non-profit 501(c)(3) organization. Its mission is to educate agencies, organizations, and the public on the problems presented by invasive plants to New York's natural communities. The IPC NYS is closely associated with the New York State Office of The Nature Conservancy (TNC), and IPC staff persons are TNC employees. The Executive Director leads the planning and implementation of the Invasive Plant Council of New York State's programs and activities. The Executive Director is responsible for developing an organizational strategic plan and annual work plans. He/she works with Council board members, public and private agencies, conservation groups, and landowners to advance the organization's mission. The Executive Director secures public and private financial resources for IPC operations. He/she directly supervises IPC NYS staff and volunteers. The Executive Director represents the IPC's mission and strategic goals to agencies, organizations, and the general public. The Executive Director is accountable to the IPC NYS Board of Directors and is supervised by the Chair of the IPC NYS Board and The Nature Conservancy's New York Deputy Director. Key responsibilities include program funding, budget administration, and financial monitoring. For a detailed job description, contact: Neil Gifford, IPCNYS Chair Albany Pine Bush Preserve 108 Wade Road Latham, NY 12110 (518)785-1888 fax ngifford(at)tnc.org --------------------------------------- 7. Literature reviews (Global) From: John Randall (jarandall(at)ucdavis.edu) Knapp, L.B and C.D. Canham. 2000. Invasion of an old-growth forest in New York by Ailanthus altissima: sapling growth and recruitment in canopy gaps. Journal of the Torrey Botanical Society 127(4): 307-315. The authors found that Ailanthus saplings dominated several natural tree-fall gaps in two small patches of old-growth hemlock forest in eastern New York state. This supports the hypothesis that Ailanthus CAN invade old-growth hemlock forests. Height, diameter and extension growth of the tallest Ailanthus saplings were significantly greater than their tallest native competitors in these gaps which were up to 23 years old. At any given gap, the ages of Ailanthus saplings differed by only 2-3 years, indicating a limited period of recruitment immediately following the opening of the gap. No Ailanthus saplings or seedlings over 1 year old were found under full canopy with the exception of a few believed to be root-borne shoots of trees growing in nearby gaps. |
