Ash Tree Die Back

Ash tree die back hit the headlines some time ago.  The melancholy fact appears to be that the UK will lose most of its current ash trees in the same way that Denmark already has.  I find the search for developing new strains of ash heartening as a solution to this problem, but it is sad to see that there is so much opposition to it simply based on the technology being new.  The Woodland Trust is quoted as saying that the "test tube" must be a last resort.  Why should it be presumed that the latest scientific research risks being disastrous?  Surely, whether a solution works or not should be assessed without worrying about whether it is based on old or new technology.
