Tree supports cause banding on model print?

[LindsayPatten 1]

The bands on the model align with the bands on the supports, and the banding on left leg starts at the level where the support branch separates from the central branch on that side.  Furthermore, the print quality on the right leg deteriorates drastically at the point where the support branch on that side separates from the central support branch.

 

Any thoughts on what the problem may be and/or how I might solve it?  I'm starting a print with the standard supports to see how that differs.
