Coppice trees Bird Conservation

A before-and-after study between 1950 and 1962 in a pine-oak forest in Pennsylvania, USA (Sharp 1963), found that the local population of ruffed grouse Bonasa umbellus declined over time, as coppiced woodlands became more mature and developed thick ground cover and mid-storey canopy. Similarly, the use of coppiced woodland by grouse broods decreased over time.
