If there’s a plant-based poster child for wildland fire in the subalpine forests of Yellowstone National Park, it would be the cone of the lodgepole pine tree. “All of these forests evolved with fire after the last glacial retreat,” said Roy Renkin, a vegetation specialist for Yellowstone National Park. “Different species have evolved different mechanisms to deal with fire.” …Renkin is one of the few people still on staff at Yellowstone who was around when the 1988 fires swept across roughly one-third of the park, charring more than 793,000 acres. Since then, he’s been witness to the rebirth of the park’s vegetation following what many at the time thought would be a legacy of scorched earth and a slow rebound.
