Flowering plants once drove a global shift in insect–plant–animal relationships and supported an increase in biodiversity, energy flux, and productivity throughout terrestrial ecosystems. We argue here that angiosperms could once again contribute to biodiversity within landscapes, if agroecosystems, and the plants within them, can be managed for multifunctional benefits. The potential for farmland to support biological diversity is understood and well-argued in the literature. We take this long-standing conversation and frame it within a longer evolutionary context, bringing attention to how modification in 2 key areas of our current food production system could support this goal. First, a move toward crop and grazing landscapes that more closely align with regional food webs can lead to observable improvements in community wildlife abundance. Second, we can re-expand the genetic base of our food, fodder, and …
