March in New Hampshire is a study in extremes—where thawing sunshine and lingering winter collide, sometimes within the same week. From record temperature swings to dripping icicles and flowing maple sap, it’s a month defined by change, inviting us to slow down, soak up the sun, and savor the small rituals that signal spring’s return.

The New Hampshire Division of Forests and Lands and Forest Society have announced the 2026 Cottrell-Baldwin Environmental Lecture Series, a free four-part program on New Hampshire’s forest history, health, and future. The series runs March 17–April 7 at the Henry I. Baldwin Environmental Center in Hillsborough.

As winter settles in, New Hampshire’s wildlife relies on time-tested strategies—from hibernation to snow-savvy movement—to survive the cold. But while this season feels especially harsh, long-term data from NOAA show winters are warming overall, with real consequences for forest ecosystems and the animals that depend on them.
