DES Warns of Expanding Infestations of Exotic Aquatic Plants (Jul 11, 2012)
New Hampshire Department of Environmental Services.
The New Hampshire Department of Environmental Services (DES) has documented two new infestations of variable milfoil, an exotic aquatic plant, within a week of each other. Both infestations were well-established when found and appear to have been present for at least 2-3 years before being reported. Infestations were newly documented at Otter Lake in Greenfield and Naticook Lake in Merrimack.

2011 Forest Health Highlights (PDF | 6.17 MB) (Feb 2012)
New Hampshire Division of Forests and Lands.
Approximately three-quarters of the forest land in New Hampshire is privately owned. Only 16 percent is in Federal ownership, which includes the White Mountain National Forest. The latest New Hampshire forest inventory estimates that there are approximately 4.8 million acres in the State that are forested. The forest resource is made up of a variety of forest types mostly comprised of maples, pine, other hardwoods, spruce and balsam fir, oaks, and hemlock. These forests provide a variety of goods including recreational opportunities, clean water, and wildlife habitat as well as paper and wood products. Keeping New Hampshire forests healthy enhances the quality of life for those who live, work, and recreate in the State.

Boxwood Blight
New Hampshire Department of Agriculture, Markets, and Food.
First identified in the United Kingdom in the mid-1990’s, it has also been confirmed from New Zealand and across Europe. The first detection in the U.S. occurred late fall 2011, with detections in North Carolina, Connecticut, and Virginia. Since those initial detections, this disease has been found in boxwoods at other locations as well. The Division of Plant Industry participated in a trace forward of boxwoods recently shipped to the state from a nursery in an infested county in Connecticut and did not find evidence of boxwood blight. The nursery industry and customers growing boxwoods should, however, be aware of and on the look out for this new disease. Please see the Boxwood blight information sheet (PDF | 1.52 MB) for more information on symptoms, life history, susceptible hosts, and suggested management of this disease. Please contact the Division if you believe you have nursery stock or landscape boxwoods infested with boxwood blight.

Statewide Ban on Importing Firewood
New Hampshire Division of Forests and Lands.
As of Jul 2011, New Hampshire has banned the importation of untreated firewood without a commercial or home heating compliance agreement. Firewood is a major source of damaging insects and diseases. This ban will help protect the health on New Hampshire's forests.
