Every summer, Dyrham Park welcomes a herd of around 100 cattle to help graze the parkland.
From May-October every year, we are joined by a herd of grazing cattle to help us manage the land. They eat the long grass so the deer can have better grazing all year round.
For centuries, this ancient deer park has been grazed by animals - including sheep and cows - and in the interests of conservation, we are carrying on this tradition.
Wildlife management plan
As well as helping us keep the grass under control, they play an important part in biodiversity - with their dung proving the perfect meal for dung beetles, which in turn are a food source for our thriving bat population.
Garden & Park Manager Dale Dennehy said: "We have to manage the 220 acres of parkland grass and although the deer are here all year round to graze the sward they cannot cope with the enormous amount of summer grass.
"It's usual practice in all parks to supplementary graze to ensure the grass remains reasonably short otherwise there would be wider access issues through waist high grass and scrub and to ensure there is a ready supply of short sweet grass for year round deer grazing."
