Diversity is the key to maximizing sustainable production from land

"Prior shorter-term studies, most about two years long, found that diversity increased productivity, but that having more than six or eight species in a plot gave no additional benefit," Reich said. "But we found that over a 14-year time span, all 16 species in our most diverse plots contributed more and more each year to higher soil fertility and biomass production. The take-home message is that when we reduce diversity in the landscape–think of a cornfield or a pine plantation or a suburban lawn–we are failing to capitalize on the valuable natural services that biodiversity provides."
