"Ohio is taking a swing at nature’s bullies.

Under new rules that went into effect Sunday, the sale and distribution of 38 destructive, invasive plant species will become illegal.

In its list, the state agriculture department included various types of honeysuckles, Bradford pear trees, autumn olive shrubs and fig buttercup flowers that line freeways, coat forest floors and choke wild spaces across Ohio.........................."

Funding for aquatic nuisance species management projects for the upcoming year is now available through the Vermont Department of Environmental Conservation.

It may be hard to believe, but the emerald ash borer or "EAB" has not been found in Vermont yet. It surrounds us on all of our borders and has taken up residence in 31 states and three Canadian provinces. In case you are feeling out of the loop, here are some great resources to help you stay up to date and prepare for the arrival of EAB. 

The winter of 2016- 2017 was a good one for hemlock woolly adelgids (HWA) in Vermont, which is probably bad news for hemlock trees. The adelgid is an invasive forest insect that attacks hemlock trees and was first discovered in Vermont in 2007. Last winter’s HWA mortality rate was only 65%, compared to 99 – 97% for the previous three years. Forest health staff with the Department of Forests, Parks and Recreation are seeking volunteers to help survey for HWA.

The growing season for 2017 saw many projects across the state tackling the forest, field, and wetland health issue of non-native invasive plants. Below are highlights of some of these amazing local efforts. Huge thanks to everyone who is working toward making our Vermont landscapes healthier and more resilient, and protecting them for generations to come.

Council Member John T. wrote to me after last summer’s ReLeaf Conference. He was surprised that in the conversations he had with other ReLeaf folks, there was little to no awareness of the Asian jumping worm (Amynthas agrestis) and how damaging it is to forests, including, one could assume, the urban forest.

Last summer, for the first time, I noticed that my compost-enriched vegetable garden soil seemed excessively granulated, and the soil was subsiding and drying out faster than usual. Turns out, the granulation was the worm castings of the voracious eater, Amynthas agrestis. I’ve since seen the big worms, and now I shudder when they appear. Read on to see why it’s now my mission to rid my garden of these worms, and why the Asian jumping worm is a concern for foresters throughout much of the country. 

Most of us have become accustomed to seeing Halloween lady beetles, boxelder bugs and western conifer seed bugs on and in our homes in the fall. Here’s a new critter to add to that nuisance list: the brown marmorated stink bug (BMSB), Halyomorpha halys.  

Water chestnut (Trapa natans) is an established invasive plant that, like many other non-native plants, escaped a cultivated life in the 1870’s to spread and grow into new territories beyond the small garden in which it once existed. Lacking any major herbivores to consume the fruit or plant, its growth consumes wide areas of water, creating impassable dense mats. The establishment of this species, if left unchecked, can severely limit boating, fishing, hunting, swimming, and other recreational activities on the water.  

Wall Lettuce (Mycelis muralis) is an early detection invasive species in Vermont. While not well established, it has the potential to spread quickly and outcompete native flora. It is a watch list species in New Hampshire, soon to be added to the watch list in Vermont, meaning the plant has invasive tendencies but is not yet prohibited.

A long-term study of managing Japanese barberry (Berberis thunbergii) shows that clearing the invasive shrub from a wooded area once can lead to a significant reduction in abundance of blacklegged ticks (Ixodes scapularis) for as long as six years.
