How lovely, and really quite astonishing. Book tourism in action. Recent visitors to my neighbour's BnB came to stay because they'd read Windswept! And others stopped her on the road to ask about it. Thank you to everyone who has bought, gifted, recommended & written about this wee book.

What will happen to the 82 USFS experimental forests around the country? Many sites have decades-long experiments that are tracking how forests are changed by timber harvesting practices and climate change. As I say here, “you can't just pick up an experimental forest site and move it to SLC.”

Warming permafrost causes "thaw slumps" that, like mini landslides, erase vegetation from the landscape. A new study tracks recovery time across the globe. Some sites take a decade, some take a century or more to recover their greenness.
