Invasives and Pests

We're grateful to The Well School's 7th graders, who volunteered to assist with our ongoing research.

Since a single ash tree is either a male or a female (in some tree species this isn’t the case and a tree may have both male and female parts), it will be important to make sure we leave some of each uncut during the harvest, to provide the species an opportunity to pollinate and set viable seed.

Leaving the mid-summer forest to the hungry biting deerflies, I spend more time mowing fields or watering and weeding the vegetable garden. Like the forest, the garden provides a miniature ecosystem to study, tend and from which to learn…

The emerald ash borer is one of several insects causing significant damage to native ash trees in New Hampshire.  It was first discovered here infecting ash trees along the Merrimack River in Concord in 2013, including ash trees located on the Forest Society’s 100 acre floodplain forest reservati

Are you noticing dead or declining trees in your forest woodlot or neighborhood?  Are you seeing tree issues that you can’t identify or have never seen before?  Join Forest Health specialists for an informative evening of discussion on tree health and common tree infections/infestations from disease and insects.  Lectures will include descriptions of common tree health offenders, and what preventative measures might be appropriate for your woodlot.

Invasive plants continue to be a serious problem for landowners and natural resource managers. Join the Upper Valley Land Trust and several invasive plant specialists to learn how to effectively combat invasive vegetation. This field-based workshop will focus on identifying invasive plants, understanding their ecology, and learning which techniques are most effective in controlling them.

New Hampshire is home to roughly 25 million ash trees. Two years ago, we learned the state is also home to a devastating invasive beetle – the emerald ash borer – which can completely destroy infested stands of ash trees in as little as six years.
