You see, this is a propagandized knee jerk opinion.

I'm not talking about monocrop eucalyptus. I'm talking within an agroforestry system as a biomass plug and growth stimulator. The goal of a great system should be to create it's own biomass, quickly, reducing or eliminating outside inputs.

If native species can't fill that niche and haven't over time why be against non native species?

I also understand being a native species maxi but there's none or very little comparable fast growing emergent strata species. One can remove them from a system when your chosen climax species reaches the emergent strata.

They've implemented these techniques using eucalyptus throughout Brazil and Central America.
