In December, a fire burned 1,050 acres at Pilot Mountain State Park. The Grindstone Fire was caused by a campfire run amok. While it caused no damage to structures, it singed a good deal of the 3,700-acre park north of Winston-Salem. And while the “damage” to the natural world may have looked significant, that’s not necessarily the case. Periodic wildfires are important to the health of any forest, which is the topic of Growth After Fire, an hour-long program at Pilot Mountain State Park Saturday at 2 p.m. “Join a park ranger to discuss fire’s effects on plant and tree growth after a fire,” according to the N.C. State Parks website. Learn more here. (Can’t make Saturday’s session? It will be repeated Sunday at 2 p.m.)
