42 acres left wild for 100 years gives rare UK woodland wildlife refuge
Ecclesall Woods in Sheffield reserved 42 acres as a wildlife sanctuary for almost 100 years, increasing bird species from 41 to 61.
In 1927, Sheffield City Council bought Ecclesall Woods and fenced off 42 acres. The area was designated as a bird sanctuary and left undisturbed for nearly a century.
Before the sanctuary was created, just 41 bird species bred in the woods. By 1980, that count had risen to 61 species.
The broader bird population also increased outside the sanctuary. Ecclesall Woods covers 346 acres in South Yorkshire and is the largest semi-natural woodland in the region.
Over centuries, humans shaped the woods through timber harvesting, charcoal production, and other uses. Yet this single protected patch shows nature can rebound dramatically when left alone.
