Nest Survival Of Grassland Breeding Birds In A Southern Mixed-Grass Prairie Wetland, Clinton Helms

Master's Theses

As a group, grassland birds have been declining significantly since European settlement of the prairie. The subsequent plowing of the prairie by settlers was compounded by fire suppression, resulting in a patchwork of cultivated fields with intermittent tracts of overgrown grassland. Over an interval of ~200 years, these practices lead to an estimated decline of 96 % of native tallgrass prairie habitat. Due to the imperiled status of grassland birds, an emphasis has been placed on managing for this particular group throughout the southern mixed-grass prairie region. I investigated the effects of adaptive three-pasture rotational grazing treatments (3ROT) versus traditional …
