A New Hampshire resident's death from EEE prompts concerns over the virus's spread, leading to nighttime outdoor activity bans in Massachusetts towns.

New Hampshire officials issued two warnings of potentially dangerous algae blooms along parts of Lake Winnipesaukee, the state’s largest lake. The New Hampshire Department of Environmental Services said on Thursday it detected high...

A storm caused flooding and road closures in New Hampshire's White Mountains and North Country, with ongoing concerns about rising river levels and dam operations.

However, numerous fishermen say the assessment of a decline in the stock doesn't match what they're seeing on the water, where haddock appear to them to be plentiful.

It has been a rough winter season for many outdoor activities in New Hampshire, but a below-average snowpack is hitting the snowmobile industry especially hard.

The black substance was staining the feet of people at the beach, prompting one local resident to alert state officials.

The state's Department of Environmental Services and Fish and Game announced effective Friday, Aug. 9 the ban on harvest of shellfish due to “red tide” is lifted for all species of shellfish except surf clams.The harvest closure went into effect May 9 for the Atlantic Ocean and Hampton/Seabrook Harbor in response to elevated levels of paralytic shellfish poisoning, or PSP, commonly known as red tide, detected in blue mussels collected from Hampton/Seabrook

The Division of Marine Fisheries is analyzing the clams and expects to have preliminary results in the coming days that might point to a cause.

Deaths of gray and harbor seals, in much greater numbers than usual, have been attributed to viruses related to distemper and the flu.

Biologists say plentiful food and other conditions are helping the rodents to thrive, and now the young ones are hitting the road.

Marine mammal experts are testing tissue samples for a potential common cause of the surge in carcasses found on the state's beaches this year.

The smelly carcass, identified as that of an adult male minke whale, is the second large marine animal to turn up on shore in southern Maine in the past week.

The storm dropped more than a foot of snow overnight in some places, making for a messy Thursday morning commute. And the nor’easter isn’t gone yet.

The unusually warm winter has proven deadly in the northeast. More than a dozen people, including snowmobilers and ice fishermen, have died when they fell through thin lake ice.

The polar bear is a powerful symbol of the effects of climate change in the Arctic.  Here in New England, our symbol may soon be the sugar maple tree. 

Three of the 15 bumble bee species found in Vermont are thought to be extinct and at least one other species is in decline.

New Hampshire Public Radio's Dan Gorenstein reports the northeastern U.S. is experiencing one of the worst droughts in decades. New, deeper wells are in demand even though they cost thousands of dollars to drill. About 40 percent of New Hampshire residents get their water from private wells. Snow might replenish some of the wells, but water doesn't permeate frozen ground.

Ice is a key player not only in the culture of the northern Northeast, but also in its unique lake ecosystems – a determinant of everything from water temperature to aquatic food chains to water quality. And according to long-term climate data, ice-out has been moving earlier and earlier.
