Habitat Associations Of Grassland Birds Along A Gradient Of Eastern Red Cedar Succession In Central Kansas, Scott W. Schmidt

Master's Theses

Grassland birds have declined more rapidly than any other avian taxa in North America. While woody encroachment is often cited as a threat, some grassland-dependent species requiring habitat with scattered trees or shrubs also are declining at statistically significant rates. To better understand the ecological costs and benefits of woody vegetation from a brush management perspective, I studied bird-habitat associations along a canopy cover gradient of eastern red cedar (Juniperus virginiana). Habitat associations were tested by the comparing the relative abundance of breeding birds between 3 habitat treatment levels (0% eastern red cedar canopy cover [open grassland], < 5% eastern red cedar canopy cover [light encroachment], and > 5-25% eastern red …
