Study finds widespread stream biodiversity declines at low levels of urban development
Date:6/8/2011

f the receiving stream. Scientists generally agree that stream degradation consistently occurs at relatively low levels of imperviousness, such as 10 to 20 percent. However, when King and his research team applied a new statistical analysis method that they created called the Threshold Indicator Taxa Analysis (TITAN), it showed biodiversity loss at much lower development levels in the study area. In fact, the analysis showed that approximately 80 percent of the biodiversity loss came between .5 and two percent of impervious cover, and the remaining 20 percent of loss came between two and 25 percent.

"This new statistical analysis method is more precise than current methods and when we applied it to real world environments, it revealed a dramatically lower ecological 'tipping point' at which species are threatened," King said. "The implications of these findings are very important in water management strategies."
