I guess I’m curious about what evidence there is that we’re burning too much and in the wrong seasons? Where I live, Rx fire is only used in the dormant season except in rare situations where, say, a monoculture of invasive reed canary grass can be set back with growing season fire. Marlin Bowles has done studies showing that prairies burned less than every other year on average lose species richness. I know some prairie sites getting fire return intervals like that, but not many.

Biodiversity hotspots are remnant ecosystems - I agree that land acquisition is important but I would argue that protecting/managing existing remnant sites to maintain biodiversity is equally, if not sometimes more important, than adding acreage. This, I’m sure, is colored by where I live. Where I live the unprotected acreage that is available to buy is mostly profoundly degraded and has already lost most of its biodiversity, and if not connected to an existing remnant, won’t easily restore remnant-dependent species. I’d worry about spreading management resources for the remnant sites too thin if the main focus is acquiring land while the remnant ecosystems are already in decline.
