There was another estate releasing a herd of water buffalo for habitat improvement for similar aims as this case. It is interesting how the release of large herbivores has such a positive effect on habitats and biodiversity. It is often the large herbivores that have the biggest, positive effect on an ecosystem IIRC. Elephants for example. I think theres similar large fauna in the seas that are considered keystone species. I think the beginnings of right whales is something like that but I only half recall the documentary on it.Today, in Guardian:Trees for Life are planning to create the first British herd of up to 15 of the animals on its 4,000-hectare (9,884-acre) Dundreggan estate near Loch Ness, in a scientific research project aimed at enhancing biodiversity, education and ecotourism.
Oh goody, more wild camping risks. Semi-wild, or wild, DNA back-bred Auroch's are unlikely to be as docile as normal cattle. At least if these get out they are possibly easier to find.
