Stream chemistry is measured at nine gaged watershed outlets. Chemical concentrations combined with
stream flow provides data on stream-water element flux for each watershed.
Calcium silicate was applied to watershed 1 as an acidification-reduction experiment.
Forty years of studying forest bird ecology at HBEF has yielded numerous major findings.
An organic stream tracer was used in Paradise Brook to study groundwater-surface water interactions.
