Oregon bans the sale of English ivy, butterfly bushes (from The Oregonian). The Oregon Department of Agriculture has banned the transport, sale or propagation of English ivy, which threatens to smother trees in Portland’s Forest Park. Sandy Diedrich would be clacking her loppers in approval. The Oregon Department of Agriculture announced Wednesday it is banning the sale, transport or propagation of English ivy, a creeping scourge that threatens to smother much of the late Diedrich's beloved Forest Park.

"Milfoil is foiled by herbicide on Minnetonka bays." As milfoil spread, so does interest in using chemicals to control it on Lake Minnetonka. Two years into a five-year test of herbicides to control Eurasian water milfoil on Lake Minnetonka, results are so encouraging that more shoreline property owners are asking for the chemical treatment in their bays.

Why Invasive Plants Take Over - Article by Don Comis, Agricultural Research Service, USDA www.ars.usda.gov/is/pr/2009/090430.htm New research shows that two key causes of plant invasion--escape from natural enemies, and increases in plant resources--act in concert. This result helps to explain the dramatic invasions by exotic plants occurring worldwide. It also indicates that global change is likely to exacerbate invasion by exotic plants.

Strategies for Effective State Early Detection/Rapid Response Programs for Plant Pests and Pathogens The Environmental Law Institute has published “Strategies for Effective State Early Detection/Rapid Response Programs for Plant Pests and Pathogens,” a report by attorney Read Porter that assesses the utility of state early detection and rapid response (ED/RR) laws for identifying and stopping the spread of invasive plant pests and pathogens. The report focuses on invasive forest pests, which are often poorly controlled by agriculture-centric response laws and which may infect or infest suburban or urban areas, raising the specter not only of environmental damage but also significant economic and aesthetic costs. The report describes components of a successful ED/RR regulatory structure, explains federal regulations that affect state action for each component, examines the strengths and weaknesses of specific laws in fourteen states that have responded to invasive pathogens, and examines the performance of ED/RR laws in practice via in-depth case studies from New York and Texas. Porter concludes that states must enact laws that balance the need for broad state agency authority to act against the need to preserve private property rights, respect landowners’ privacy, and sustain public support. This report was produced by the Environmental Law Institute with funding and guidance from The Nature Conservancy. The report is available free of charge from ELI’s website, at www.elistore.org/reports_detail.asp?ID=11223.

Invasive Plants to Watch For!
Photo by Stephen Darbyshire, Agriculture and Agri-Food Canada, Ottawa, Ontario, Canada, 2002. .................................................................................................. Indiana's "Most Unwanted" Invasive Plant Pest Web site - The Indiana Cooperative Agricultural Pest Survey (CAPS) program, which is a collaborative effort between Purdue, the USDA's Animal and Plant Health Inspection Service division of Plant Protection and Quarantine, the Indiana Department of Natural Resources, and the Indiana chapter of The Nature Conservancy, recently launched a new Web site highlighting Indiana's "most unwanted" invasive plant pests, http://extension.entm.purdue.edu/CAPS. People can search the site by the pest's name, the commodity it attacks or by its habitat. The Web site reports the pest's known distribution and whether it is currently present in Indiana . Visitors also can learn which invasive plant pests are found in specific Indiana counties. .................................................................................................. The Midwest Invasive Plant Network (MIPN) would like your help to evaluate research priorties and foster interactions between researchers and land managers working on invasive plants. If you work on invasive plant issues in the Midwest, please click the link below to complete the MIPN survey on research needs for invasive plants: www.surveymonkey.com/s.asp?u=37222162906 Results of this survey will be used to help direct our activities , focus research, and strengthen the community of people working together to reduce the impact of invasive plants. Thank you for help, John Cardina, Ohio State University & Chair of the MIPN Research Committee and Kate Howe, Coordinator for the Midwest Invasive Plant Network ..................................................................................................
