FROM GOLF GREEN TO GREEN STREAM: DOES TYPICAL RESTORATION HIT A HOLE IN ONE?
A major debate in ecology is how biodiversity loss impacts ecosystem function. This topic
is particularly important in aquatic systems as anthropogenically driven declines in biodiversity
are over five times greater in freshwater than in terrestrial ecosystems (Ricciardi & Rasmussen, 1999). Furthermore, typical aquatic restoration efforts focus on biological integrity for the evaluation of restoration success, ignoring another important measure of ecosystem health, functional integrity (Gessner & Chauvet, 2002). Therefore, this study examines how stream restoration influences not only biodiversity of macroinvertebrates, but also the rate of leaf litter processing. Leaf litter bags were deployed throughout the Chagrin River Watershed (Ohio, USA) in restored, unrestored, or reference streams within two reclaimed golf course sites and one old-growth forest. Fungal colonization, macroinvertebrate communities, and leaf decomposition were then measured over four months. Tentative results demonstrate no difference in the biological processing rate or invertebrate communities on leaf bags between restored and un-restored sites, despite differences in benthic communities published in restoration reports. These results further support the need for changes in how restoration success is measured, and the importance of restoring ecosystem function through the restoration of impaired reaches.
