Sycamore Bleeding Canker?

Went to look at a hedge job the other day and the customer asked me to check out a strange substance bleeding from her Sycamore.

The tree is tri-stemmed, forking only a couple of feet from the ground, has slight included bark and seems to have had some slight excavator damage at the base some 8 or 10 years ago by house builders. Not a large tree, approximately 35-40feet, but one main stem leaning towards the house, and one towards a busy A road.

The "bleeding" appears to be coming from along side the fork union and above the damage, so in quite a crutial place.

Sorry for the appauling discription, but forgot my camera! I can get pics soon, so if anyone wants them, i can put some up.

So, has anyone experience of Canker in Sycamore, and is it likely to cause a risk to the structural integrity?

Pics please

Yes boss, will do today:001_tt1:

David, is it possible to get canker on Acers?

Eere ya goo.................

I've seen that before although not sure what it is.

I'd have thought the structural integrity was questionable regardless of any possible infection.

Thats a bleeding canker, thats also a big point of failure at the included bark. What is the rest of the tree like, if throughout other stems then i think it is probably best to remove, cambium and phloem affected, along with weak union and prevailing winds, the sheer loading aint going to be that great. one puff of wind and it could fail. Go on man assert your authority. You know you need to

Ok Russell, it seems you are the only one willing to say it is definately a canker. The tree is otherwise relatively healthy, but not really the issue. The main purpose of the thread is about the canker.

I am somewhat suprised that there has been very little in the way of feed back on this thread. I realise as many others of us do, the included bark is potentially a serious problem for the future, and the tree should probably be removed, but i was hoping for a bit more input for those, such as my self who dont have the vast tree biology knowledge.

So, is there anyone else who would like to elaborate a little more, such as aggression of canker in sycamore, and even similarities to other more vulnerable species, even just for the sake of educating us?

I haven't any experience of Bleeding on Acers.

Have you ruled out Armillaria Pete ?

Once the Rhizomorphs and mycelium get to the vascular system, it is possible to see bleeding/gummosis from bark and wounds on trunks.

Suppose this is what i'm getting at david, seems a bit of a strange one on acer.

As far as honey fungus goes, there is no mushroom smell, no evidence of "threads" of white film below the bark, there is no fruiting body present at the base of the tree, and none noted by the customer in the past, so i guess thats ruled out.

The mystery continues......

18 Stoner, I am no Biologist either but I think all our large broad leaves are under threat from this type of canker at the moment.

Its seems to me that environmental factors, heat from the sun and unpredictable patterns of rain and snow, larger popluations of tree pests are all having detrimental affects on trees globally.

I know I am all just doom and gloom but I personally see our long term environmental future as being very bleak - with no other option than letting nature, the planet adapt as it must.
