Global Invasive Species Team listserve digest #010 Wed, 6 Jan 1999 17:17:09 -0800 (PST) --CONTENTS-- 1. Weed survey halls of fame and shame 2. Purple Loosestrife videos 3. Euphorbia cyparissias --------------------------------------- 1. Weed survey halls of fame and shame From: Barry Rice (bamrice(at)ucdavis.edu) We are *really* encouraging the stragglers to finish the weed survey. I have posted on our web site the names of those fine folks who have completed the surveys (thanks), at http://tncinvasives.ucdavis.edu/survey.html Count the stars next to your name! In the same vein, I have also posted the preserves lacking survey coverage. See if you think your state has been adequately covered. --------------------------------------- 2. Purple Loosestrife videos From: Kyle Stockwell (kstockwell(at)tnc.org) Here is some information about videos on biocontrol of Purple Loosestrife, from Cornell. "Rearing of Biological Control Agents for Purple Loosestrife," 1998, 24 minutes. Shows natural resource managers, entomologists, horticulturists and educators how to rear host-specific enemies to control this plant. These natural enemies have the ability to reduce the abundance of purple loosestrife to less than 5 percent of the pre-release levels." "Restoring the Balance: Biological Control of Purple Loosestrife," 1997, 28 minutes. Reviews the invasion and spread of purple loosestrife, describes management alternatives, gives reasons for biological control and shows the importance of restoring diverse plant communities in North American wetlands." Both videos are available from the Cornell University Media and Technology Services AV Center, 7 BTP, Ithaca, NY 14850 for $24.95 each, or $36 for both titles if they are ordered together."

Euphorbia cyparissias From: Bruce Hammond (bhammond(at)tnc.org) TNC's Massachusetts Islands Program is confronting an infestation of cypress spurge (Euphorbia cyparissias) at our Katama Plains preserve. This species is closely related to leafy spurge (E. esula), which I understand often invades midwest prairies. Can anyone suggest effective control strategies for E. cyparissias? Thank you!
