Global Invasive Species Team listserve digest #029 Fri, 23 Apr 1999 16:38:30 -0700 (PDT) --CONTENTS-- 1. Weed videos 2. New book on Florida weeds 3. Lesser celandine 4. Honeysuckle-Rose control II --------------------------------------- 1. Weed videos From: Ed Smith (ebsmith(at)flagstaff.az.us) Ed wrote from the northern Arizona Program to learn if any TNC programs have produced a video on western weeds. If so he would like permission to copy it and to distribute copies to smaller community groups, developers, real estate folks, NRCSs, equestrian clubs, etc. in lieu of making presentations in person. Ed is also interested in your recommendations of videos produced by other groups that he might use for the same purpose. --------------------------------------- 2. New book on Florida weeds From: Doria Gordon (dgordon(at)botany.ufl.edu) Identification & biology of non-native plants in Florida's natural areas. 1999. K. Langeland and K.C. Burks. University of Florida Institute of Food and Agricultural Sciences SP 257. $16.00 + $4.00 S&H. This field guide covers 62 non-native plant species that are invasive in Florida's natural areas. Intended as a tool for land managers, the guide contains descriptions and photographs for identification and provides details about the ecological significance, distribution and life history of these plants. See the IFAS website for ordering information: http://ems.ifas.ufl.edu/forsale or call (800) 226-1764 from 8-5 eastern time Mon.-Fri. --------------------------------------- 3. Lesser celandine From: Ellen Jacquart (ejacquart(at)tnc.org) Ellen claims to be writing on the behalf of a "friend." Ellen says she doesn't have this weed on her Indiana preserves, but that a "friend" in Indiana does. Uh huh. I would like to hear from anyone who has ever attempted to control _Ranunculus ficaria_ (Lesser Celandine, a buttercup with small round leaves which grow from underground nutlets). Especially if you succeeded. On the Web, this plant is described as invasive in MD, VA, WV, DE, and PA, but it is plenty invasive here in Indianapolis, too, where neither I nor anyone I have asked has succeeded in controlling it. I am mainly concerned about our own yard, but I also have seen this plant in 3 wooded parks in the area. Thanks, Liz Day <daylight(at)indy.net> --------------------------------------- 4. Honeysuckle-Rose control II From: Bill Kleiman (nachusa(at)essex1.com) Honeysuckle: We tend to cut the stems and paint or spray the cut stump with 35% garlon 4 in mineral oil with a red basal dye. We stack the cut stems in piles, usually. Multiflora rose: Good fires will top kill the plant. We spray the resprouts when they emerge and green up with Garlon 3A in water, or other broad leaves foliar herbicides. For big plants that we can't top kill with fire we cut them down with clearing saws, brush mowers, loppers, and treat cut stumps with Garlon 4 in mineral with red basal dye. |
