Lodgepole pine has closed, serotinous cones, that require 🔥︎ fire to open the cones and 🌱︎ allow the seeds to germinate.
It is also the primary tree in 🏞 Yellowstone National Park, where after a century of fire suppression, lodgepole pine was aging out — on the way to being replaced by other species. Until the
🔥︎ Yellowstone fires of 1988
swept through — although the fires killed many adult trees, it allowed the 🌱︎🌱︎ new generation to germinate and grow.
