2005, Book chapter, Bird Conservation Implementation and Integration in the Americas: Proceedings of the Third International Partners in Flight Conference 2002
Land managers are often concerned with providing habitat affords the 'best habitat for songbirds.' However, unless management simply is directed at rare species it may not be clear which habitats or management options are best. A standard, quantifiable measure to compare the significance of different tracts of land...
Waiting for trees to grow: nest survival, brood parasitism, and the impact of reforestation efforts
K.R. Hazler, D.J. Twedt, R.J. Cooper
2005, Book chapter, One Hundred and Twenty-Third Stated Meeting of the American Ornithologists' Union: abstract book
Of the forested wetlands that once covered the Mississippi Alluvial Valley, only -25% remain due to large-scale conversion to agriculture. Reforestation efforts are currently underway, but tracts planted with slow-growing oaks maintain the structure of a grassland for 5 yr or longer, and will require at least 40 yr...
