Researchers at the University of Leeds said reintroducing wolves to the Cairngorms, as well as the south-west, north-west and central Highlands could help control the problem of red deer eating trees, which stops natural woodland regeneration.The scientists estimated that if wolves were reintroduced, a population of about 167 of the animals would thrive, which would be enough to reduce the red deer population to a level that would allow trees to regenerate naturally. This alone could contribute to about 5% of the carbon removal target for UK woodlands, roughly equal to 1 million tonnes. Each wolf would lead to an annual carbon intake capability of 6, 080 tonnes of CO2.The study's lead author, Prof Dominick Spracklen, said, "The positive effect of biodiversity on the climate cannot be overlooked. We need to look at the potential role of natural processes such as the reintroduction of species to recover our degraded (退化的) ecosystems and these in turn can deliver co-benefits for climate and nature recovery. "It is widely accepted that wolves were eradicated (根除) from Scotland about 250 years ago, leaving red deer with no natural enemies. Over the last 100 years, while efforts have been made to control the population, it has increased to an estimated 400, 000 today in Scotland alone. The researchers said only 4% of Scotland was covered by native woodland today, making it one of the least natively forested places in Europe.The researchers have expected some strong reactions against their research, particularly from deer chasers and farmers concerned about their cows or sheep. The policy of reintroducing wolves in Scotland has been intensely opposed by some farmers and rural communities.Lee Schofield, a co-author of the study, said, "We recognize that actual and wide-ranging stakeholder (利益相关者) and public engagement would clearly be essential before wolf reintroduction. Most importantly, conflicts between human beings and wildlife must be addressed through public policies that account for people's attitudes for a reintroduction to be successful. "
