What factors dertermine speed specific drag?

I imagine some of these will involve tradeoffs with productivity.
For example, single leaf area is positively correlated with growth
but probably also increases drag.  This kind of thing is especially
important for poplar plantations east of Cascades, where winds are 
generally strong.  Can productivity be maintained while reducing
drag by deploying more but smaller leaves?
