Habitat-based planning tools are a cornerstone of conservation in forested ecosystems, but remain a novel approach in grasslands. In Chapter 2, I develop spatially-explicit habitat models as decision support tools for conservation. I survey birds, measure local vegetation and quantify landscape features at 952 sites in western Minnesota and northwest Iowa. Findings indicate that cropland provides little habitat for grassland songbirds and that hayland does not compensate for loss of grasslands. Multiscale models …
