Bill Mollison says that nature's best condensers are shrubs in the 1-3 meter height range. Also, in certain areas, up to 80% of the moisture that the ground receives is from condensation. So my question is this: Are there certain plants that condense more moisture than they require?
I live in Tulare County, CA, the top ag county in the world by most measures, where annual rainfall is 9" on a good year (which we haven't had too many of lately). I'm in the process of designing a model food forest for an awesome organization. As a primary strategy, I've envisioned planting key food trees in large (15' diameter), wood-chip mulched circular depressions that will act as watersheds for the tree in the middle. What I'm wondering is whether and which plants could function as "condenser plants." Of course, the hope would be to also stack functions: nurse plant (initially), nutrient/mulch accumulator, food production (human/chicken/wildlife), etc.
Thoughts on this strategy and suitable plants? Thanks
