At our Insh Marshes reserve, we're introducing a small herd of Koniks to trial grazing the reed, which is spreading and reducing the quality of the fen habitat. Over the next few years, we hope the impact of the ponies will help improve the important wetland habitat for rare plants, insects and birds. Watch the herd gain three new members and find out from Pete Moore and Theo Jones why these ponies do such an important job for us.
