In the Forest Insect and Disease Conditions Report for 2019, we shared that an isolated patch of what was suspected to be Japanese Stiltgrass (Microstegium vimineum) was reported in Sandgate in late 2018 (Bennington County). At the time, there had not been botanical confirmation of the presence of that plant, because the site was treated as part of a private land management project. A potential roadside site for this plant was reported in October 2019 in Brattleboro (Windham County). It was previously thought to be absent from Vermont, but these recent sightings provided by the public through the Report It feature on VTinvasives.org, have led the Vermont Natural Heritage Program to photographically confirm the populations in Bennington, Rutland, and Windham County, but do not have vouchers.
In our last issue of the VTInvasives e-newsletter, we discussed a new method of treating knotweed by using wire fencing laid horizontally on the ground over a patch of the offending species. Over the past two months, I have received several emails from readers asking some clarifying questions and looking for updates. I apologize for not being able to reply to everyone, and I hope that this article can provide an update with some answers.
There’s a patch of Japanese knotweed growing on the edge of a town park near my house that I see every morning when I walk my dog. It hasn’t started sending up green shoots yet this spring, but there can’t be too many more days before it does. For the past few years, this patch has been there, steadily growing and spreading each season, slowly creeping more interior into the forest each summer.
This April, I am observing the first days of spring like most of you are: from my home office, socially distant from my friends and co-workers. Spring seems to be arriving this year without much fanfare other than a late season snowstorm, but in the teleworking times that we are living in, its arrival is still a thing to celebrate. In fact, being able to observe and enjoy the daily changes this seasonal transition brings during such a stressful time is a silver lining that I’m holding tightly on to.
White fringetree was discovered to be a secondary host of emerald ash borers in North American in 2014, but researchers at Wright State University have found that white fringetrees in low-density ornamental landscapes were not a significant reservoir for emerald ash borer.
White-tailed deer are deeply rooted in our landscape and our state’s identity. They are a native species and play an important role in our ecosystem. However, transformations in our forest structure from centuries of land use changes, the removal of predator species like the gray wolf and mountain lion, and a warming climate have cumulatively allowed for deer to expand their range and increase their population in our state. Increased sprawl and suburbanization have also put these habitat generalists into our backyards and lives more than most people would like. Unfortunately, whether it be in the form of vehicle collisions, garden and landscape damage, or the increased prevalence of Lyme disease, negative encounters with deer are becoming more common for people in Vermont.
The colder temps and flurries of snow may make plant identification a thing of dreams for the coming summer. But one common invasive plant in Vermont can still be easily spotted throughout the winter months: common buckthorn.
It is hard to believe that the Forest Hero! Network is fast approaching its 1st birthday! To celebrate, we'd like to share with everyone, the good work that volunteers are completing in their communities. If you are working on a project and would like to help inspire others who may be seeking ideas, please write in and we'll share in future newsletters!
Amur Maple, Acer ginnala, belongs to the Sapindaceae family, which now includes previous members of Aceraceae (maple family). It is native to northern China and Japan, and was introduced into North America in 1860. Beginning in the 1950s, Amur Maple was reported as “locally established”.
On a sunny evening in May, about 30 environmental practitioners from around Vermont gathered at the Craftsbury Outdoor Center, where the snow had just about melted. As loons called on Big Hosmer Pond, and the worlds of natural resource regulation, conservation, and education clicked on outside, this group spent two days immersed in a concept that is at once head-smackingly simple and deceptively complex: a land ethic.
Water Chestnut is an annual aquatic plant that is invasive in Vermont. The water chestnut population has been managed by the Vermont Department of Environmental Conservation (VTDEC) since the early 1980s and, for the past few summers, crews from the Vermont Youth Conservation Corps (VYCC) have been supporting VTDEC’s hand-pulling efforts.
Vermonters know that our hot and humid summer weather has really settled in once our fields and roadsides start popping out in colorful blooms of chicory, Queen Anne’s lace, black-eyed Susan, orange hawkweed, and feral daylilies. It’s a beautiful time of year in our state, and it’s also a time of year when our songbirds start fattening up for their winter migration and our native pollinators begin to collect and store pollen and nectar for their young to feed on over the winter.
As we progress into summer heat waves and holiday vacations, many plants have flowered and started to go to seed. One invasive plant, Japanese barberry (Berberis thunbergii), at this point in the season (July/August) will have seeds forming and ripening.
