Shropshire firm fakes beaver attacks in seed experiment

A Shropshire company is banking on an experiment to help increase the seeds it gathers from aspen trees.

Forestart gather the seeds of native trees from all over the UK to sell on to nurseries.

But they have real problems with the aspen tree, which prefers to send up tiny suckers through the ground around the tree, rather than offer up seeds.

BBC Midlands Today Environment Correspondent David Gregory-Kumar met Rob Lees, from Forestart, who explained how they hope to persuade the aspen to give up more of its seeds - by tricking it into thinking it is under attack from beavers.
