Something has hit your tree. You might want to figure out what that was so that it doesn't happen to a decent tree in your yard. If the tree was only recently planted, it could have been something that happened during the transportation or planting processes. I would be more concerned that the Cleveland pear was still standing than that it had been damaged.

Mechanical damage of some sort. If recently planted by others, probably careless handling during loading, delivering and or planting. If the tree is healthy it will callous and grow new bark in time.

Thanks. It was recently planted (today in fact). I am happy to hear that. Still contacted the contractor as if something comes up down the line want some documentation of it. I do have a warranty for a year and will keep an eye on it during that time frame.

What state are you in? Clevelands may be an invasive there as here. My state DNR would rather we don't plant them.

In about 10-12 years, you'll regret planting them.

Not in a million years would I accept a tree with that kind of damage.

Steal, I won't pile on to the derision towards this invasive plant. Oops....I guess I just did. In any case, I tend to agree that mechanical injury was a likely cause of this canker or canker-like lesion. The truth is in the pudding, that being in this case whether or not the tree is able to form woundwood/callus tissue to close off the wound from the outside. Too early to tell. If it should happen that the wound does not close, then you've got some infectious agent or other happening there, and these are typically next to impossible to treat. But for now, no special requirements beyond the usual-keep the tree watered if drought should strike. Not much beyond that, and even that only in extraordinarily dry circumstances.

If it's a brand new planting and "they" did the work, there is no way in heck I would accept that kind of damage. In fact, I would tell them to remove it immediately, and I would make a better choice about what to plant for the replacement.

cut it down, and plant something else. the flowers smell like Bradford Pear (fish smell) and they are highly invasive, but if you must keep them I have to agree with wisconstitom

They are prone to ice/snow damage as well as being invasive in all but the dry or really cold parts of the country. So many more long-lived and less smelly choices. Here's a set in my neighborhood after 6" of wet snow.

Since it's new and the damage implies that it should be replaced, can you consider another type of tree? I hate to see a tree just start to put on good size and then do what the ones in the photo did.

why not

Amelanchier arborea

or

cercis canadensis 'royal white'

or

cercis canadensis

or

cercis canadensis 'forest pansy'

I know I listed lots of redbud trees, they are my favorite spring flowering tree. you should check them out.

The cleveland's have a different branching structure than the bradfords so i would not really worry about it falling apart in later years. (although some might disagree)

I certainly would (disagree)! And, there's still all the other problems, too.
