Federal Definition of Invasive Species
The Invasive Species Advisory Committee of the National Invasive Species Council (NISC) has released a white paper that clarifies the federal definition of "invasive species" and gives some criteria for considering species to be invasive or not.

Tiny Bug Attacking Hemlock in Kentucky (Examiner)
The exotic insect, called the hemlock woolly adelgid, has been detected in only two Kentucky state parks, but the minuscule aphid-like insect has already destroyed hemlock trees throughout Appalachia. The only thing standing in the way of safeguarding Kentucky hemlocks is the lack of funding, said Tim McClure, a state forest health environmental scientist.

People Think Trees Need More Protections (News Sentinel)
Knox County Tennessee residents value their trees and would like to see more of them saved from the developer's ax, but they don't want regulations on private landscaping, according to a new University of Tennessee study.

Now is the Best Time to Look for Gypsy Moth Infestations
With leaves falling or down in many areas, now is the best time for property owners to determine whether the gypsy moth will be a problem on their property next year. Gypsy moth populations collapsed in 2004, but have risen since then because the last two summers have been warm and dry, state forestry health specialist say, but they caution that the gypsy moth could be at outbreak levels in parts of eastern and central Wisconsin next summer.

Fall is Open Season for Hunting Invasive Plants
Now that the frost has hit statewide, state invasive species specialists say it is a good time to hunt for and control certain invasive plants because they tend to stay green longer than native plants, making them easier to spot. But they caution that people who venture out into woods and fields also need to be careful not to inadvertently spread more weeds around.

Land Enlisted to Fight Floods (Journal Sentinel)
More than 1,000 acres of wetlands and meadows along creeks and rivers in the five-county Milwaukee metropolitan area are being enlisted in a regional effort to prevent flooding and reduce the need for building costly levees and other flood control structures in the future. "We're using nature to help us solve the problem," states Kevin Shafer, the district's executive director.

Educating Hunters about Firewood and Emerald Ash Borer
Foresters and pest specialists from two state agencies will be talking to hunters about transporting insects and diseases during a two-day firewood blitz at travel centers in southern Wisconsin. The campaign will take place on Thursday and Friday, Nov. 16 and 17, just prior to the opening of the state's regular gun-deer hunting season.

Arborists Crucial Role in Preventing EAB Spread (Tree Care Industry)
Learn about the crucial role arborists play in preventing the spread of EAB in this article written by Judy Antipin of the Forest Service and published in the November, 2006 issue of Tree Care Industry magazine.

Illinois Department of Agriculture Expands Emerald Ash Borer Quarantine
The Illinois Department of Agriculture has expanded its emerald ash borer quarantine to part of a second county infested with the tree-killing beetle. In addition to 51 square miles of Kane County, where the pest was first detected in the state, the quarantine now includes 64 square miles of northern Cook County. The Cook County quarantine extends north to south from the Lake County line to the northernmost city limit of Chicago and east to west from Lake Michigan to Interstate 294.
