Global Invasive Species Team listserve digest #016 Wed, 27 Jan 1999 18:07:53 -0800 (PST) --CONTENTS-- 1. Krenite, and Kite Aerial Photography 2. Mapping Weeds 3. Mapping Weeds, and Hackberry Control 4. Japanese Climbing Fern (Lygodium) --------------------------------------- 1. Krenite, and Kite Aerial Photography From: Peter Dunwiddie (pdunwiddie(at)tnc.org) I've used Krenite as a foliar herbicide on scrub oaks (about 10 years ago now when it worked quite well. We did some pretty careful checking on its toxicity, and it was pretty innocuous compared to almost everything else. ---Peter also mentioned the value of photomonitoring by kite photography. If you don't think this method can get good results, take a look at the amazing images on the "Kite Aerial Photography Webpage" at http://www-archfp.ced.berkeley.edu/kap/ --------------------------------------- 2. Mapping Weeds From: Alan T. Carpenter (atcarpen(at)bouldernews.infi.net) Montana State University Extension has produced a booklet that describes a protocal for weed mapping with GPS units. The publication is Mapping Noxious Weeds in Montana and is available free from Ag Extension Communications, Montana State University Extension, 416 Culbertson Hall, Montana State University, Bozeman, MT 59717. - Alan Carpenter --------------------------------------- 3. Mapping Weeds, and Hackberry Control From: Carlen Emanuel (cemanuel(at)zebra.net) On Mapping weeds. Our in-between high and low tech effort is somewhat laborious but exceedingly effective for us. Alabama Natural Heritage Program uses DeedPlotter to map plant communities (mostly we do it on a small scale, 1-12 acres by the traverse method because our GPS is only accurate within 5-10 meters). We can map areas 1X1 m and larger and compute acreage, insert sampling designs, permanent plots, etc. We have adapted the uses of DeedPlotter to produce excellent detailed maps of our monitoring projects. Contact me and I'll explain more. Cost approx $400. On Hackberry. Garlon 4 or 3A applications, either on cut or non-cut stems. Don't mow--you're just creating a tremendous root system waiting for a release. --------------------------------------- 4. Japanese Climbing Fern (Lygodium) From: Rick Studenmund (rstudenmund(at)nettally.com) Lygodium is found all over Florida panhandle gulf coast in wet areas, especially river floodplain forests. In uncut bottomland hardwood forests it is especially insidious because it quietly hangs in shady places for a long time and explodes when the canopy is opened - especially by clearcutting. Then it inhibits regeneration by its ability to smother seedlings or sprouts. With the potential for pulp market changes in the future that could promote bottomland hardwood cutting, Lygodium could become a bigtime problem. Beware cutting these forests with any evidence of Lygodium! We have not tried any control methods. --------------------------------------------------------------- |
