In the 1990s, driven grouse shooting and habitat management stopped in the Berwyn Special Protection Area in North Wales, leading to a serious fall in bird species.
Research into changes in upland bird numbers and distribution between 1983 and 2012 revealed stark findings.
The complete loss of lapwing and serious and rapid declines of many other red listed birds were highlighted. Hen harriers dropped by 48 percent, golden plover by 90 percent, curlew by 79 percent, ring ouzel and black grouse by 78 percent and red grouse by 54 percent.
The Berwyn report demonstrates with great clarity the consequences of losing grouse shooting as a land management tool. The report shows the hugely important work of MA members in their care for 860,000 acres of heather moorland in England and Wales. Without this work, the precious land would revert to scrub and forest and the heather moors lost forever, along with the loss of many red listed birds.
