Fair enough Ben, but what's the solution and can you tell what 9 across is 
while you're at it :-) ?

On a serious note, don't earthworms have a bulk density 'ceiling'?

Scatter earthworms liberally?

Just add a small point to Alastair's "fill-ups" of mulch, a few months 
ago Tony Kirkham was showing the AARCs around Kew and surprised us all 
by saying that just simply topping up mulch was something he no longer 
indulged in. The reason is that the existing mulch by weathering and 
footfall actually formed a barrier and new mulch on top was of 
significantly reduced effectiveness.
This may be a symptom which affects Kew given the number of visitors, 
but actually the proportion of people who do actually trample on mulch 
is comparatively low.  For what it is worth, on the one hand I'm in no 
position to contest Tony's knowledge and experience, but on the other 
it seems to me that if existing mulch has "hardened off" then it 
should be raked or otherwise disturbed so that any "layer" can be 
broken and the new mulch integrated.
It does depend upon whether mulching is a restorative measure over the 
short term, or a longer term measure.  That would depend upon the 
site, but if as you say the foliage indicates that the tree is OK, 
that may be a good sign in terms of the former, but again you don't 
mention the period over which trafficking over the root system 
occurred or how long ago it was reduced by the diversion.  As with all 
things to do with trees, it is all down to justification in 
site-specific circumstances, but in general I reckon that mulching is a 
"good thing".
Soil type??

Thanks Alistair & Edmund.  I didn’t give enough info!

The compaction is less than a third of the actual rooting area but is 
quite severe (construction traffic for rebuilding collapsed listed 
building
etc) and the fungal bodies sit against the buttresses of the roots 
from the compacted area.

The traffic will continue to some extent (access for three workers 
houses) so I need to do something to sort the issue out and they are 
going to resurface anyway so it needs to be done with my input rather 
than just that of the builders who caused the damage.

I have been waiting a wee while, and whilst doing so I advised the 
owners to reroute the heavy traffic and consider putting the tree in 
my care.  The crown isn’t showing any signs, no die back at present.  
But the fungal infection is evident for the second year (sadly they 
keep calling me in after they’re past their best).  I think the owners 
hoped it would go away, but it hasn’t, so they’re now inclined to let me do 
my best for the tree.

The direct damage to the exposed roots makes me inclined to do more 
rather than less.  I feel if we can improve the situation it would 
give these roots a chance of recovery.

Your thoughts are much appreciated
Charlie

"Wait and see", maybe? As for retrenchment pruning, you might follow 
the dieback with the saw, but the dieback itself can tell a story.

Subject: Another big Beech to care for.

Hello All,

I have a client with another very large Beech with a partially 
compacted
rooting area (caused by excessive traffic for the type of surface, 
some surface root damage and some fungal fruiting bodies of possibly 
honey fungus (rotted down so difficult to tell).  Stem is sound, crown 
is stunningly perfect. Owners are aware of risks and would like to 
maintain tree for as long as possible.

Ideally I’d like to arrange decompaction/aeration, root 
investigation,
mulching, create a new driveway surface (including cellular system and 
permeable surface) and create an aesthetically pleasing barrier to 
stop traffic cutting the corner again and causing direct damage to the 
exposed roots.  Majority of traffic has already been diverted, but 
some access to the rear of the property is still required (I did 
suggest moving it all but that was a step too far).

In the long term I have warned that systematic retrenchment may be
required as well as the above, though I am loathe to do this to a 
beech and such a fine specimen.

I ask for any sources of information, guidance, or research on 
similar
cases.  Also, of any contacts for advice or the decompaction, aeration 
and root investigation that cover the north west of England.

And of course if there is something that I may not have mentioned as 
a
course of action you feel would be pertinent in saving this ‘big Ol’ girl’
from past poor management, please do let me know.


Best Wishes
Charlie
