Abstract

Bird nesting patterns were studied under various grazing regimes in southern Iowa.

Key Question

Can farming in Iowa can be compatible with successful grassland bird populations?

Findings

Yes, grazing lands, in particular, can be compatible IF there are areas that are undisturbed during the grassland bird nesting season (particularly May and June) and the grazing lands are diverse, both in terms of species (warm-season grasses, cool-season grasses, a variety of forb species, including legumes and composites) and in structure (some bare ground, clumps of tall dead standing grasses, etc.). While some refuge areas of ungrazed areas (like diverse CRP) are still necessary, careful management of grazing lands through rotational grazing of cool-season and warm-season grasses will allow grassland bird populations to persist.
