English longhorns returned to Wanstead Park in August to graze until the beginning of September.
“These mowing machines perform a good job at grazing the area selectively, which is uneven due to anthills. They also eat tougher plant life, which prevents the area from becoming too overgrown and allows more diverse flora to establish. And their dung is home to a wide variety of beetle and fly larvae, which provides food for birds. So, their presence is of great benefit to the ecosystem,” said volunteer cow warden Karen Humpage.
