Urbanization, long-term stream flow variability, and redside dace status in Greater Toronto Area streams: Fs97-4/3118E-PDF

"Redside Dace (Clinostomus elongatus) is a small, colorful cyprinid found in the pools and slow-flowing sections of small Ontario streams. As a result of recent declines and threats to remaining populations, the species has been assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) and the province of Ontario as Endangered. Habitat degradation caused by urban development is considered a primary threat. However, a clearer understanding of urban development impacts is still required to inform status assessments, and the degree to which the supply of suitable habitat meets current and future needs of the Redside Dace. In this study, hydrometric data for 6 Greater Toronto Area watersheds was used to characterize long-term (1966 to 2013) trends in stream flow condition (quantity and variability) for Redside Dace populations of differing conservation status"--Abstract, p. iv.
