Long-term stream data in BES

The watershed approach, which is based on long-term monitoring of the quantity and quality of streams, has long been used to study whole-ecosystem function. Applying this approach in BES allows us to compare urban ecosystems with the more natural systems that dominate the LTER network and to produce data on whole- ecosystem function at a scale relevant to management. In this talk, I present data from the first six years of long-term stream monitoring for BES and address questions related to 1) natural variation in watershed ecosystem function, 2) the effect of land use on water quality in time and space and 3) temporal variation in urban water quality.
