Maintaining habitat variability helps to increase biodiversity. Over the past century, forest clearing has lead to the degradation of native habitats such as grasslands, forests, and shrublands in the Northeast. Recently, both grassland and forest bird communities have been the target of major conservation efforts. In contrast, successional habitats, such as shrublands, have largely been ignored. The deterioration of shrubland habitats has led to a significant decrease in the abundance of many shrubland bird species in the Northeast, including the golden-winged warbler (Vermivora chrysoptera), Bellís vireo (Vireo bellii), and American woodcock (Scolopax minor). In order to manage and conserve shrubland bird species, we need to understand how vegetation structure and habitat area affect shrubland species diversity. In my study, I will be using double-observer point counts to identify birds in various anthropogenic and natural shrubland habitats. Shrubland habitat will be described using various vegetation measurements such as shrub cover, height, composition, and photosynthetically active radiation.
