This paper describes a stream biomonitoring program that builds capacity in undergraduate college students in the field of freshwater ecology and conservation. The program involves sampling of aquatic macroinvertebrates and hydrological parameters in streams of the state of Meghalaya, India. Several colleges from Shillong initiated short-term, one-year and long-term biomonitoring of streams in East Khasi Hills and Ri-Bhoi districts. Nine stream locations sampled over October-December in 2014 provided a snapshot of physical and biotic conditions, thus enabling the examination of spatial trends in water quality parameters and aquatic biota. A year-long sampling study from 2014-2015 provided a seasonal view of stream parameters at Lwai (clean) and Umkaliar (moderately polluted) streams. Results from both sampling sets suggest that turbidity negatively affected the richness of pollution sensitive taxa. Dissolved Oxygen values were lower in polluted streams and were non-significantly lower in summer than in winter. After an initial training in the field, the sampling was conducted by college students under supervision from their lecturers. Data obtained on macroinvertebrates adds to the sparse information available on stream ecosystems in the biodiversity-rich northeast Indian region. We hope the paper provides a template for monitoring of vital ecosystems in this and similar regions.
