If it's to be wildlife, most important thing will be to have some sort
of ramp up to the edge so amphibious wildlife can get out.

A friend finds that frogs seem to have no problem in near vertical smooth
sided containers in her garden. And their tops are about 30cm above ground
level. No idea how they get in or out.
