Some councils in England have come under fire for unnecessarily felling old healthy trees to make way for regeneration projects. In Plymouth more than a hundred mature trees were chopped down despite public disapproval, and in Sheffield an independent inquiry found that the council's destruction of thousands of trees was misjudged. National Highways, the government agency responsible for England's main roads, has also admitted that more than half a million trees it planted beside a single 21-mile stretch of new carriageway have died - with the cost of replanting them now £2.9m. On the Sky News Daily, Sally Lockwood finds out what is going wrong with regeneration schemes in Plymouth and Sheffield with local campaigners, and speaks to our people and politics correspondent Nick Martin about why local tree rows have become such a big deal.
