EWEST,

I certainly agree with your comments on Dave and look forward to reading that article. Dave knows that I tried to study under him, but the hurricanes this fall precluded that for me, unfortunately.

The question I was trying to raise was "does it really make a substantial difference to BG recruitment sandy bottom vs gravel beds"?

If a pond has otherwise poor conditions for spawning, i.e. all hard clay bottom, then it certainly stands to reason that addition of gravel would make a difference. My question was more subtle, I guess, and born out of observing huge numbers of very close proximity BG beds in sandy areas of my ponds. Would adding gravel increase the number of beds? I don't see how physically that is possible, but certainly look forward to being proven wrong...again. \:\)
