O dear. I'm afraid I can't agree with you about Brumby damage, Hannah. Brumbies aren't native to our country: they were brought here, just like foxes and rabbits and cats. Check out the water holes where the horses and cattle pug (trample) the edges with their sharp hooves, killing the native grasses, mosses and sedges that bind the banks. Without them, water run-off increases in leaps and bounds and can leave the high-country at serious drying risk in the heat of summer.
Our native flora evolved to co-exist with soft-footed native fauna, not hooved beasts like horses and cattle and sheep. All three of those should be *gone* from the sensitive parts of the high country! It's bad enough that much of the rest of the country is given over to the accommodation of livestock, but our Alpine meadowlands are so limited and so delicately balanced, they really do deserve to be protected from hard hooves and heavy grazing.
I don't believe in the cruelty of aerial culling, but I do think moves should be afoot to muster the Brumbies and put them in less sensitive areas where they wouldn't do so much unfixable damage. If it weren't for that bloody poem (which, don't get wrong, gives me goose-pimples every time I read it), something sensible would have been done about the Brumbies years ago.
I've been a horsewoman all my life, so please don't think I'm a Brumby-hater! It's just that I've also spent a lot of my life studying Australian ecosystems and I hate to see so many species disappearing needlessly.
