I have a land cover layer from which I've extracted the tree canopy class and set all values that are not tree to NULL. I've also converted it to a vector and exploded it to make single part features.
I want to classify each patch into "small" (being very small trees along streets or in fields), "medium" (groups of backyard trees clustered together/ in small parks) and "large" (legitimate forested areas such as town forest and the like).
However, there are some medium and large patches that are connected by a very small "bridge patch" resulting in humongous patches that should be a large and medium patch, respectively. It's a mostly residential area bordering public parkland so there is much more dense tree canopy than you see here (also a 6 sq mile area).
I have access to data like roads, town boundaries, etc. etc. No special data or anything not available publicly (from USGS or other sources). I do have the Spatial Analyst and Patch Analyst extension (among others) as well as an ArcGIS for Desktop Advanced License.
For a little visualization of the data I'm working with:
Edit:
I do have an update on this problem. For whatever reason, the issue with the buffer I mentioned above did not occur the second time I tried it and produced a layer that I then used to create the forest patches. I did try the thin tool to see what kind of layer it produced and ended up with something looking like it came straight out of Tron. I did try "expanding" this layer but I ended up losing much of the integrity of the original TC layer.
