Once again: the world is on fire. As wildfires burn across Canada and their smoke pours down the continent, we thought it would be a good time to encore these Fire Ecology episodes. First, Dr. Gavin Jones brings the heat talking about what fire is, how hot it burns, fire trends, tinderboxes, lots and lots of forest fire flim-flam, tolerant wombats, Angelina Jolie movies, cunning pine cones, thick bark, Indigenous fire stewardship and more.Then, join co-host of the podcast Good Fire, Dr. Amy Christianson, to learn about how cultural burns and prescribed blazes can create healthy forests. She also discusses Indigenous history, collaborations between Western science & First Nations elders, Aboriginal thoughts on cultural burns, more flim-flam, evacuations, snowmelt, hunting strategies, land stewardship, happy trees, climate strategies, and the social science behind wildfire education. Also learning from Native wildfire fighters. Huge thanks to her and Matt Kristoff -- who also hosts the Your Forest Podcast -- for allowing us to use excerpts from their interview to launch Good Fire.
