There is an unwelcome earthworm in our midst.

This comes as no surprise to folks with an aversion to slime.

But to gardeners and farmers who rightfully tout the contribution of most wrigglers to soil health, this is hard news indeed.

Bragging rights have been handed down for generations: Plots dotted with fertile worm excrement (castings); clods riddled with worm holes (...

UXBRIDGE — In a wooded residential area off Route 122, a team of foresters and entomologists took turns looking through a scope at a small hole in the bark of a maple, maybe 55 feet up. Everyone agreed the damage came from a bird, probably a woodpecker, and not the Asian longhorned beetle.

A very good thing, since the invasive insect is not supposed to be this far beyond the infestation...

An annual report on the health of Vermont forests identifies some trouble spots but says overall, it was a good year for trees.

Because Vermont is 78 percent forested, the health of the state’s hardwood and softwood species is important.

State and federal foresters are looking for an eastern hemlock version of Superman.

Their search for a “bulletproof” genetic strain of Pennsylvania’s state tree is an important part of a new, multi-branched plan to save as many of the stream-shading evergreens as possible from an invasive and voracious Asian insect, the hemlock woolly adelgid.

WARWICK — The winter moth, an invasive spring leaf-eater that in recent years has punctually emerged after Thanksgiving to swarm in startling numbers in the beams of Christmas lights, could be enjoying one of its last holiday seasons.

And the owners of hardwood trees and fruit growers across Rhode Island and Massachusetts can thank an introduced parasitic fly for the moth’s eventual...

Windsor — It will come as no surprise to Windsor residents to hear Barbara Rhoad speak fondly of one of nature’s grandest icons.

“I’ve always loved trees,” Rhoad said, providing a simple but enthusiastic response to why she has spent 20 years as a volunteer planting and caring for...

KANSAS CITY, Missouri—Forester Kevin Lapointe remembers clearly the day he and his colleagues at the Kansas City Parks and Recreation Department did their first autopsy on a dead ash tree. Under its peeling bark, they found S-shaped burrows running across every inch of the outer layer of wood. Looking closer, they discovered the killer: a slender green beetle smaller than a penny.

Aliens are coming to Williston.
Metallic-green beetles will arrive from out of state, perhaps on a truck full of firewood. They will find home in the town’s many ash trees, munching leaves and mating. Females will lay eggs in the bark.
When larvae hatch, the destruction begins. They feed on tissue that carries water and nutrients, killing the tree from the top...

MADISON, Wis. — The state Department of Natural Resources' board could add scores of organisms to Wisconsin's invasive species list next month in the first revisions to the catalog since it was created five years ago.

The DNR has proposed classifying 49 more species as prohibited, which means people can't sell, possess or...

Early detection of the Elongate Hemlock Scale (EHS) is key to keeping Vermont’s forests healthy and functioning.  This invasive forest pest from Asia threatens hemlock trees (Tsuga canadensis).  Hemlock is Vermont’s 7th most common tree.  It provides many important ecological functions such as, providing winter shelter for wildlife and shading streams to keep...
