I think there is some scope for further guidance in that case as this is going to be a huge issue imo.

 

 

 

Sorry Pete, the forthcoming Technical Guide (TTG3) is the 'rigging guide' which obviously will cover anchor point selection, strengths and weaknesses etc. albeit not specific to ADB.

 ash is pretty brittle to start with

That'll be why they made axe handles from it then ?

 

I felled some large affected ash last week, 60% crown dead, and there were definite signs of something strange in the basal cross section. Whether it was a secondary infection or signs of the chalara  infecting the whole sapwood band I'm unsure. The hinge was still as normal.

I am expecting some areas where "clumps" (for want of a better word),  of ash trees may need felling. If this is the case I will have to determine whether immediate replanting should take place on banked areas to avoid landslip!

Sounds strange, after we felled trees, and treated stumps, on a steep chalky embankment we had to go back and pull the stumps out as they came loose several years later.

 

Remember when the railway was built there were no trees and kept that way by the deveg gangs

Strange to me too. IIRC someone mentioned about how stumps of infected trees were coppicing the following year, before that foliage got re-infected. I'd imagine the remaining roots would stabilise the bank for a number of years while nature took its course and new self-seeded saplings became established. 

 

As a sidebar Paul, when did you become qualified enough in geology/geography to determine where the angle of repose would lead to slippage?

Perhaps my terminology was not on point thur my man. Perhaps if i said it doesnt hold a hinge as well as some of the other brands of trees.

One things for sure when adb branches hit the floor the make hell of a mess! Need to purcahse a road sweeper, did have one by chance go up the road i was working the other day saving me some work!

I'd take issue with that too as one of the reasons healthy ash will barber chair is the high strength of the hinge

What do the experts on here make of this slightly encouraging story?

 

Certain landscapes show resistance to ash dieback

Some habitats can help dampen the spread of ash dieback, which threatens ash trees.
