| Notes | The Umpqua River was dredged in September, 1987 at the entrance of Winchester Bay. NMFS investigated the materials disposal site to assess the impact of disposal on benthic fauna. Sediments were sampled before and after dredging. The Umpqua showed high species diversity at low density (122 different invertebrate taxa) before dredging, and even higher diversity with higher density after dredging (144 taxa). The authors discuss possible reasons for the surprising increase in benthic invertebrates following this dredging. |
