Project Description

This project will test whether structural retention, whereby plant detritus (logs, bark, leaves) is trapped and
retained within river channels, can offset the impacts caused by widespread clearance of vegetation along
river banks, a widespread problem in Australia and the world. Theoretically, retention is a major
environmental driver of ecosystem change in rivers, but this has rarely been tested, particularly in a
restoration context. We expect to show that increasing retention results in higher species diversity, thus
providing managers with a relatively straightforward method for improving the environmental conditions of
