Global Invasive Species Team listserve digest #052 Mon, 17 Jan 2000 15:27:36 -0800 (PST) --CONTENTS-- 1. Help with Scotch Broom (Washington) 2. Goats (Pacific Northwest) 3. New Weed Alerts on the weeds web site (Nationwide) --------------------------------------- 1. Help with Scotch Broom (Washington) From: Barry Rice (bamrice(at)ucdavis.edu) Pat Dunn (pdunn(at)tnc.org, TNC Washington) talked with me on the phone regarding his problems with Scotch Broom (Cytisus scoparius). Pat has a huge infestation on his hands where plants are invading prairie. He has used the 2,4-D and triclopyr herbicidal mix (Crossbow) with success, but he is trying to expand his approach. Does anyone have experience with killing large amounts of Scotch Broom? He is considering trying a boom applicator fitted with wicks. If you have any experience with buying and using wicks, Pat could benefit from your wisdom. If it would take too long to email, call Pat (360-956-9713) or me (530-754-8891) and we can talk. Thanks! --------------------------------------- 2. Goats (Pacific Northwest) From: Callie Hurd (kalaphia(at)aol.com) The Southern Oregon Goat Producers are promoting the use of goats for weed control throughout the Pacific Northwest. They claim to have had great success in controlling leafy spurge on 2,000 acres of private land on Marsh Creek near Pocatello, Idaho. Using 600 goats and 2 herders over a 5-month period during the growing season, the goats reduced leafy spurge infestations significantly. Unlike sheep, goats will eat all the above-ground parts of the leafy spurge plant, including woody stems. In addition, they prefer leafy spurge over many native species that sheep would normally prefer. However, goats do require intensive management (e.g., trained herders) to prevent them from damaging native vegetation. The plan for Marsh Creek is to continue intensive goat grazing for 5 years and then maintain leafy spurge control through short-term grazing once or twice a year thereafter. Long term goals including incorporating 100 goats into the cattle herds at Marsh Creek, thereby providing long term weed control and two cash crops - cows and goats. SOGP is working with chefs in Portland to promote the use of goat meat in restaurants and thereby increase the commercial value and demand for the animal. Anyone interested in learning more about how goats can be used to control weeds or how to find goats in your area, contact Sarah Bunten, President of SOGP at 541-947-2691 or of SOGP at 541-947-2691 or hbsb(at)ptinet.net. --------------------------------------- 3. New Weed Alerts on the weeds web site (Nationwide) From: Barry Rice (bamrice(at)ucdavis.edu) Just a quick announcement that we have added two new weed alerts to our home page. The first is for the mustard, Coincya monensis (Isle of Man Cabbage) which has appeared in Pennsylvania, New York, Michigan, Kentucky, and California. The second is for a grass called Ventenata dubia (hairgrass) which has been found in Montana, Idaho, Utah, Nevada, California, Oregon, Washington, and Wisconsin, and in a number of Canadian provinces.
