Scientists say there is hope that some ash forests will be able to survive a devastating tree disease.
Scotland’s biggest private landowner, the Duke of Buccleuch, has called in a government commissioner to intervene in a row between his estate managers and agricultural tenants.

Investors have seen strong returns for two decades, and despite some predictions that the top of the market may be close, few are choosing to cash in their chips.
Significantly fewer trees are being planted on Welsh farms despite financial incentives to encourage farmers to create new woodlands, prompting fears of a possible future timber shortage.
There are about 78,000ha of farm woodland in Wales – about one-quarter of all woodland in the country.
But the latest Woodlands for Wales indicators report shows that just 141ha of new woodland was planted across Wales in the year to March 2016 – 102ha of broadleaves and 39ha of conifers.
The sale of a large block of commercial forestry in a sought-after region of Scotland has opened with strong interest.
A resurgence in firewood and timber prices combined with strong returns for investors is leading to heightened interest in UK woodland and forestry.
Commercial forest owners have seen the value of their asset rise exponentially in the past 10 years.
And, over the same period, some woodland deemed unworthy of maintenance is now financially viable again.
“Forestry has made a total return of 18.4% a year in the past decade,” says Jason Beedell, research partner at Strutt & Parker.
