One of the thing we use our grazing animals for during the summer is scrub control. This particular area has been grazed by Exmoor ponies to knock back a lot of scrub regrowth in the centre of a woodland. At one time this area was an open glade but it has slowly been lost to scrub over the years. Now that the scrub has taken a big hit this can be backed up with some annual late summer grazing which given time the this will open up the glade again for butterflies and other invertebrates.
