Environmental Effects of Dredging: Long-Term Biological Studies in Bottomland Hardwood Wetlands, Cache RIver, Arkansas.

摘要

A wetland evaluation technique developed for the Federal Highway Administration (Adamus 1983) was revised by the US Army Engineer Waterways Experiment Station (WES) and published as an operational draft (Adamus et al. 1987). The Wetlands Evaluation Technique (WET) provides an assessment of 11 different functions. This operational draft will be revised and refined during the next several years to improve its technical accuracy. One major revision planned during this period Is improving the technical accuracy by developing regionalized wetland evaluation models. Research initiated by WES in bottomland hardwood wetlands will provide information necessary to develop these regional models for this wetland type. This technical note describes biological research underway in bottomland hardwood wetlands along the Cache River in Arkansas. JMD.
