whats this?

Could be frost damage for sure. Red maples are susceptible to it, even without hollow centers. Lots of sap running, thin bark, freezing conditions, bang.

Wounds from scratching creatures as in squirrels, porcupines, etc. They lap the sweet sap.

Looks too high for those critters to scratch it from the ground, though I have not seen a porcupine on its hind legs.

if not, seems unlikely they could do that kind of damage while hanging upside down.

Of course I do not have a better theory...
 
Here is another photo from the same tree. These bulges were atypical of varmit damage. The interior wood below the sapwood was bulged as well. Didn't appear to be from freezing though was my first inclination too. I am not going to rule it out. Thanks for some input. Area college (clemson) pathologists tested for pathogens and found none. Let me know if you have any other ideas.

Bulges got me stumped, and i see red maples every day; lots. one small bleeding lesion; flare looks good.

You are "up north" but near Clemson?? Region would help here.
 
The specimen came from a transplanted (from where I dont know) maple in Greenville, SC. The tree had declined severely, Another transplant from the same nursery was healthy and standing 15 ft. away.

my guess would have been frost until you posted that pic with the bumps. could the bumps be a gall or canker from a wasp or other insect, and the tree has some bad frost cracks as well. what side of the trunk are the cracks on, south?
 
Now that you said it was a transplant, I would guess that it could be root decay working its way up the tree, with the bleeding canker as the obvious outward sign. Still a guess though.

Your profile says you are a branch manager in Michigan, this tree and the area docs are from South Carolina... I am officially confused. It wouldn't matter that much if we weren't all wondering about frost damage.

Yes.

aka from 3 days ago: You are "up north" but near Clemson?? Region would help here.

Too many needless variables spoils the mystery.
 
Yes, again the tree was located in Greenville, SC. These pictures were taken in July, 2008 if I recall correctly. The specimin was sent to clemson for examination which was returned with "no" bacterial or fungal pathogens present. No staining in the wood and no insects found in these bulges. There were some borers present in some of the split wood but these were belived to be a secondary pest.

I honestly threw this one on the back burner due to a lack of resources.
To answer your question about location I have relocated to the great state of MI because of the booming economy. HA! Thanks! again for your input.

Seemed a little confusing that some of the injury was on the lower side of the limbs.

[/ QUOTE ]That is putting it mildly--so is this tree still there, or cut down?
