Abstract: | The potential of powerline rights-of-way to provide songbird habitat in an urbanizing environment was assessed over a 7-month.period. Comparisons of species richness and total number of birds observed were made with a nearby residential development. The right-of-way, for 7 years free from herbicide manipulation, exhibited a greater number of species (but fewer individuals) and higher bird species diversity (BSD) than the residential area. The importance of mixed-shrub communities for the provision of niches for songbirds was demonstrated by increased BSD in residential vacant lots and sections of the right-of-way containing a variety of vegetative profiles. Recommendations are presented on right-of-way vegetation management to enhance songbird utilization. |
