All 2025 New Hampshire Fires · 12 fires
A fire is listed here when it is located in New Hampshire. Each complex is counted once, through its parent: the parent carries the complex's acres, and its member fires are listed beneath it without being counted again. A fire that crossed the border is listed with the acres that burned in New Hampshire, not its whole reported size. A fire located elsewhere that burned into New Hampshire is listed too, at its New Hampshire acres, and is not added to the New Hampshire fire counts.

Burn severity · New Hampshire 2025
Burned acres in New Hampshire for the 2025 season, split by how severely each cell of ground burned. Each figure counts the 30 m cells inside a fire's latest mapped perimeter, measured from satellite imagery. The Fires tab carries the reported season acreage.
Severity comes from the differenced normalized burn ratio (dNBR), the same index the federal burn severity programs publish, classified with the standard thresholds.
This is an initial assessment. Trees keep dying for months after a burn, so severity in forest reads conservative until the official assessments arrive after the season.
