Video – a real treat.

In 1995 wolves were reintroduced to Yellowstone; this gave biologists a unique opportunity to study what happens when a top predator returns to an ecosystem. They were brought in to manage the rising elk population, which had been overgrazing much of the park, but their effect went far beyond that. Many of you will have seen this video, as it did Facebook rounds a while ago, but whether you have or haven’t, I watched it again this morning while celebrating the recent protection of the beaver here in Scotland. Long live the beaver.

  1. I’ve seen this vido before, it’s amazing! I’m glad beavers are going to be protected. I am not sure wolves are ever going to be re-introduced though as British farming became kind of ‘lazy’, as predators who would eat sheep haven’t been around for centuries. Farmers are not willing to cope with it, it would be much more work then just let the sheep graze freely all year around. When I was in Transylvania 15 years ago they had shepherds and dogs all day long with the sheep and they would be taken into an enclsure for the night with 4 ‘bed-boxes’ around it for the shepherds to sleep in with a gun, to protect them from wolves and bears. I just can’t see this happening here unfortunately.

  2. Very aposite. Both wolves and beavers are keystone species and have the power to transform and enrich depleted landscapes, returning them to their natural biodiversity. Wolves do it by changing the behaviour of inguoates and reducing their capacity to destroy forests by intensivevubiwuitous grazing. Beavers do it principally by increasing the amount of water lying on the land, and a few others things as well. When you get both wolves and beavers things really zoom ahead!
