The health of New Hampshire’s forest is defined by its ability to maintain native biological diversity and remain vigorous while sustaining its role in the environment and socioeconomic world.  A myriad of factors such as air pollution, urban sprawl, introduced insects and diseases, catastrophic weather events, demand for wood products, and wildlife populations continuously affect the health of forests in New Hampshire.  It’s a testament to good soils, adequate rainfall, and dedicated landowners that New Hampshire is the second most forested state (by % of total area) in the union.  However, our forests look very different from the forests found here centuries ago, and the current forests are not in perfect health.  New Hampshire’s forests require constant monitoring and management to stay ahead of the current and potential threats.

The Forest Health Section within the Forest Protection Bureau monitors the condition of the State's 4.8 million acres of forest. The program was established as the “white pine blister rust control program” in 1917.  In 1965 the WPBR control program was expanded into a more general “Forest Insect and Disease Program” with as many as eight full time specialists working on pest issues throughout the state.  In 1997 the forest insect and disease program was again broadened to the current title “Forest Health Section” to reflect the increased scope of forest health issues beyond just insects and diseases.
