    First up, an article about this: https://www.greenmatters.com/news/2018/02/19/2m3wbf/border-collies-forest

    It doesn’t give much more info other than looking at the share scale of the destruction and the speed at which the doggos can cover the terrain! Looking into it a bit further it’s clear that when fires are this intense, they can sterilize the soil, destroying not just the trees/plants but also the seed bank and mycorrhizal networks that help forests regenerate. Plus, by choosing the seeds they spread they can convert areas that were overtaken by introduced species back to native ones. Natural seed dispersal can still happen by wind or wildlife but this can be much slower meaning regrowth is delayed meaning soil erosion can occur. Not all heroes wear capes, some wear leeetle backpacks!

    It’s an odd thing to do as forests naturally regenerate after fire and you don’t want to mess up the ecology by introducing new species or genetic variants. Definitely cute but odd.

      Climate change has increased the frequency and intensity of wildfires and decreased populations of seed-spreading and pollinating animals. The forests might be able to regenerate, but not at the rate at which they burn down.

      And I’m positive that whoever is doing this makes sure they’re using native seeds.

        They probably aren’t actually doing this though - native seeds are a pain in the dick to collect - you’re not going to waste them strapping them to a dog lol

          I volunteer at a preserve that has a “farm” for exactly this reason. Native seeds are gathered in the preserve, grown out on the “farm”, and then are harvested and regrown for a few years to build up a seed bank.

          At the end the seeds are scattered by volunteers. Dogs aren’t allowed in the preserve (it’s a sensitive habitat) but if they were this might be one of the rare situations it would make sense. There are lots of rattlesnakes though, so even then it wouldnt be safe for the dogs in the right season for the seeds.

          The “farm” we have consists of 4 10ft by 20ft raised beds protected from deer by a tall fence. So far it seems to have made a significant long-term improvement in some areas of the preserve (at least as far as ratio of native species to introduced)
