(Global, Planet Earth) --------------------------------------- 1. New Zealand flatworms? (California, USA)
I have been contacted by a Californian home owner who believes he has New Zealand flatworms (Arthurdendyus triangulatus) in his lawn. No joke. Has this been reported in the USA before? Does anyone know of this creatures impacts? A quick web search indicates this organism will never win any beauty contests, and may give me nightmares tonight. --------------------------------------- 2. Are you on an invasive species council? (Global, Planet Earth)
Team) to know what TNC staff are also serving on invasive species councils. If you are now, or have ever been, a member of an Invasive Species Council, please contact me. --------------------------------------- 3. Information needed on wall lettuce (Mycelis muralis) (Vermont, USA)
Society have found scattered populations of an exotic lettuce in Nature Preserves and other high-quality areas. It seems to love rich northern hardwood forests and other mineral-rich soils and doesn't mind cold winter temperatures. Has anyone else found populations of this plant? What control and management has been used? Any information on the plant's behaviour would be greatly appreciated! --------------------------------------- 4. I want Japanese knotweed! (Massachusetts, USA)
knotweed (Polygonum cuspidatum) and am looking for people to donate leaf samples of knotweed from across the U.S . --------------------------------------- 5. New peer-reviewed journal on invasives (Global, Planet Earth)
-- "Invasive Plant Science and Management" -- in early 2008. The journal will link science and management with peer-reviewed research articles, reviews, and case studies. See http://www.wssa.net/WSSA/Pubs/IPSM.htm --------------------------------------- 6. Get your work profiled on nature.org (Global, Planet Earth)
If you're doing cool stuff, and want to have it profiled on nature.org, contact me. I'm not promising anything, but I'll see what we can do! --------------------------------------- 7. Pediomelum pentaphyllum and Cirsium wrightii (Southwestern states, USA;
Pediomelum pentaphyllum (Chihuahua scurfpea) lives in mesquite habitats in a few counties in Arizona, New Mexico, and possibly Texas and Mexico. Cirsium wrightii (Wright's marsh thistle) is known only from marshlands in New Mexico, Texas, and Mexico. I am looking for any information on the status of these plants, including threats such as those from invasive species. --------------------------------------- 8. Weed propagule removal system (California, USA)
invasive species propagules off boats and fire crew equipment. This is a pretty intensive piece of equipment that is mounted on a trailer to make it mobile. Take a look at the web site here: http://s-k-enviro.com/ --------------------------------------- 9. New invasive species weed books! (Global, Planet Earth)
new books that have recently come my way that all have excellent photos, descriptions, and are each noteworthy in their own particular way. Read on! "Invasive Plants: A Guide to Identification, Impacts, and Control of Common North American Species" by Sylvan and Wallace Kaufman and is available through Stackpole Books. Some of you on this listserve may remember Sylvan and her excellent post-doctoral work on Berberis thunbergii (Japanese barberry) at TNC's Berkshire Taconic Landscape project! This book begins with several excellent introductory chapters on the history, impacts, management, and challenges associated with invasive species, then the bulk of the book works as a field guide to the most common plant invaders across North America. Each entry has a short description of the plant, identifying characteristics, great photos (many taken by GISI staff!), and there is also habitat and range information, and a summary of impacts and management. The authors intended this book to serve as a portal to further information on invasive species by providing resources, links, and exemplary references for each species, and they have done a great job of doing just that. Additionally, both Sylvan and Wallace are available and willing to give a variety of lectures on invasive species topics! http://www.invasiveplantguide.com/ Invasive Species in the Pacific Northwest" eds P.D. Boersma, S.H. Reichard & A.N. Van Buren. Is there anything that Super-Sarah Reichard cannot do? This book is intended as sort-of a "coffee table book" in that there are descriptions of the 100 worst invasive species (all taxa) in the Pacific Northwest, with some general, specific and a bit of gee-whiz information about each species. Each description includes photos, a range map across the PNW, an overview of the impact of that species on communities and native species, history of invasiveness, and a quick management summary. The most interesting part of this book (for me) was how they decided on which species to include by using a ranking system similar to that used by NatureServe, Cal-IPC and others, which is described in detail in tables in the appendix. http://www.washington.edu/uwpress/search/books/BOEINV.html "Weeds of Califonia and other Western States" by Joe DiTomaso and Evelyn Healy. How many weed scientists/managers do you know also have a background in plant taxonomy? How many of them are able to create a compelling and comprehensive weed identification guide for the entire Western U.S.? The answer--is probably not many! However, Dr. Joe DiTomaso and Evelyn Healy have created a must-have book for your bookshelf! Have you long struggled with the not-great photos and dubious species organization of Weeds in the West? If so, this new book is for you! Joe and Evelyn's new publication as a big 2 volume book set, with an accompanying CD of all of the awesome photos included in the tomes! This new work includes awesome photos of all plant life stages, detailed technical descriptions, tables, compares closely-related and often-confusing species, and is THE most complete work on western weeds that I have seen. While it does include some native species, it is intended to be inclusive of all "weeds" of landscapes, gardens, turf, crops, rangelands, utility sites, and wildlands. http://www.calweeds.com/shop/agora.cgi |
