Hello and welcome to spring!
Yesterday a Grand Fir (Abies Grandis) at the Ardkinglas Estate, Scotland, was climbed by local arborists and measured by tape drop to be 64.24m, beating two Douglas Firs measured last year, both at 63.79m (one of which measured by me). Here is the link to the BBC video:

Safe Dave and I are off to the Coed-y-Brenin forest next weekend to do the first comprehensive survey of the rapidly growing trees there, so maybe one of them might be even taller already!
