Description:

holes apparently hacked 1 cm apart uniformly around trunk or branches of young Alder and/or Beech. Trees gushing with clear liquid for 3 days. As if a woodpecker had shuffled around the tree whilst drumming. Who knows what this phenomena is?

I'm told woodpeckers will do

I'm told woodpeckers will do this to get at the sap. Hence the American name - sapsuckers.

that's the best and most

that's the best and most cogent suggestion yet. I'll try and research the woodpecker's habits further, I wonder if a Nuthatch might do something similar. some are in lower trees at about 2m high, but still above the main trunk thickness where the stem starts to taper, as if it really did know what it was doing

apparently there are Borers

apparently there are Borers which the Woodpecker will go after, doing damage to the tree, all the actual Sapsuckers being American, I believe. Particulaly Birch, but also Beech and Alder it would seem have their own Borer beetles

If it was going after

If it was going after beetles, I think it would have done much more damage. I was once shown a horizontal row of peckings on a tree in Thetford Forest and was told they were caused by a woodpecker extracting sap. That is as much as I know about the phenomenon unfortunately.
