Restoring functional links between riparian zones and streams by enhancing structural retention
Grant number: LP140100054 | Funding period: 2015 - 2018
This project aims to 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. The aim of this project is to show that increasing retention results in higher species diversity, thus providing managers with a relatively straightforward method for improving the environmental conditions of rivers, while simultaneously testing three hypot..View full description
