Urbanization is transforming the South. And as forests and farms are converted to urban land uses, there are environmental consequences—reduced water quality, invasive species, and loss of habitat for native wildlife and plant species. The changes also have implications for disease vectors, such as birds and insects that can carry West Nile Virus (WNV), Lyme disease, and more recently, the Zika virus.
One group of researchers has been looking at the connection between a wide ranging but integrated group of factors in the transmission of WNV—the loss of forest cover, increases in impervious surface, reduced water quality, socioeconomics, and other factors—that may play a role in supporting the bird and mosquito populations that are key in the spread of WNV.
Graeme Lockaby, a research professor with the School of Forestry and Wildlife Sciences at Auburn University, has been studying the impacts of forest conversion on water quality for decades. In recent years, he has been working with an interdisciplinary team of researchers, including Wayne Zipperer, SRS-4952 research forester; Wayde Morse, a social scientist, and Latif Kalin, a hydrologic modeler, both with the School of Forestry and Wildlife Sciences at Auburn; and Navideh Noori, a hydrologic modeler at the University of Georgia. The team has been looking at how urbanization affects streams, creeks, and rivers in a range of settings from rural forested areas to the inner city.
