North Andover’s Osgood Hill Conservation Area contains over 3 miles of trails that connect to many more miles of trails on other properties, frontage on Lake Cochichewick, and a historic building, the Stevens Estate, which the town owns and uses for events.
What is the emerald ash borer?
The emerald ash borer is a small insect that bores into the bark of ash trees, eventually killing them. The insect is a small beetle, approximately 1/3 inch in length with a shiny green exterior. It is native to Asia and was first discovered in the United States in 2002 in Michigan. Since then, it has spread throughout the central and eastern US and its presence in Massachusetts was confirmed in 2012.
Why should I care about this insect?
The sale of wood products such as mulch, pulp, and firewood are an important source of income and a sustainable means of heat production for many New England homeowners. With the arrival of the Emerald Ash Borer (EAB) and the Asian Longhorn Beetle (ALB) to Massachusetts, the sale and movement of these products are now subject to new restrictions and regulations.
As if the hemlock woolly adelgid and the asian longhorned beetle weren’t enough, the emerald ash borer is in Massachusetts and they have come for our ash trees! Learn more about the emerald ash borer.
Late last year EAB was found in the town of Dalton in Berkshire County. Two months ago, it was detected in North Andover, the first detection in Eastern Massachusetts.
Forest health is always a topic of great interest for most woodland owners. One insect that has received a lot of attention in recent years is the Hemlock Woolly Adelgid (pronounced a-dell-jid).
The Hemlock Woolly Adelgid is an introduced pest, believed to be a native of Asia. White cottony sacs as the base of the needles are good evidence of an infestation. They are present throughout the year, but are most prominent in early spring. The Hemlock Woolly Adelgid migrates an estimated 10-20 miles a year, transported primarily by wind, birds and humans.
Although seeing trees lose their leaves in the fall can be a beautiful sight, it can be quite disconcerting when it happens in the spring. Many parts of Massachusetts have seen a significant amount of defoliation this year because of high populations of two caterpillars: 1. forest tent and 2. Eastern tent. You may have even noticed the crowns of some of your own trees looking a little thin. In order to deal with these caterpillars effectively, it is important to be able to distinguish them a part.
Massachusetts forests are under pressure from numerous invasive exotic insect pests. One of these latest pests is the Emerald Ash Borer (EAB). This Asian beetle, discovered in 2002 in southeastern Michigan and Windsor, Ont., infests and kills North American ash species including green, white, black and blue ash.
