At our Abernethy reserve, we are embarking on an exciting trial to introduce cattle grazing to a section of the forest. The reserve is an important site for capercaillie, which are scarce and highly localised in the UK. We're trying to improve the rare Scottish native pinewood habitat they can be found in, with cattle grazing and trampling the field-layer. We hope this will lead to increases in blaeberry and the invertebrates that feed on it - a key food source for capercaillie chicks. Mike Butler who helps look after the herd tells us more.
