What are peoples thoughts and opinions (felling vs retaining) on a largish sycamore with Kretzschmaria deusta, considering the target would be a busy main road... (on the other side of the screen planting)

 

I have my own thoughts and opinions.... anyone else?

Once kretz is established, on most species, I feel the trees days are numbered. Sycamore and lime in my experience cope even less well than beech with kretz. Given that it results in a sudden brittle fracture with no warning, I'd be very uneasy retaining a sycamore that size with anything more than rural fields or fences etc as possible targets. Even then I'd be looking to reduce the sail/weight of the crown. If that's a tree you're giving advice on, my money is on it being little more than a stump with wiggly black lines in it within 6 months

As above. Perhaps leave as monolith if targets allow.

In my experience, Kretz, along with whatever the primary agent is, will make fairly quick work of a sycamore. If it's near a road, I think it would be prudent to remove it.

 

There's a time and a place for standing habitat.

What side of the tree is the Kretzschmaria infecting and is there a predominant lean to the tree?

 

Whats the occupation of the field?

Managing trees with structural problems is all well and good IF you can exclude a target.

 

If you cant and the tree causes damage despite your measures you are well and truly in the pincers.

Agreed Scott and quip.

 

I've recommended this for removal (already had before posted, just wanted to see what the consensus was). Pics aren't great to be honest but Crown is weighted towards the road and kretzsch is on tension side of root flare. This is the first of two syc's on site with visible fb's out of 14 large sycs.

 

David at the moment it's just fields to the west and road to the east but it was a 5837 survey for a potential development.

Hi All,

I may have posted these before on another thread, mature Sycamore near school entrance. Upper canopy showing peripheral dieback, fruiting bodies and stump.

Excellent thread, and piccies, as always!

 

Thanks all..

A couple of months ago i happened to notice immature and mature fb's on the base of this Sycamore, noticed it was a little sparse in the crown and considering it was well within striking distance of a bus stop, two well used footpaths and fairly busy road, and close enough to clip a block of flats and a house, it was a tricky one as it was a dominant tree but a call had to be made to the TO.

Obviously there is uncertainty with K.d, but as it's difficult to test you just have to weigh it up, having done so i was curious to see extent of decay.

 

We took it down today, removed the crown, felled the stick at a couple of foot then took a couple of rings off below that, then cut stem into discs.

So photos show the tree, the fb's, decay in the stump, decay lower down the stump, then decay working up the stem.

 

With hindsight i think that perhaps it could've gone on another two or three years, but the decay is well established and i'm not sure which is the lesser of two evils; remove or retain?
