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 hypotheses about rectifying ecosystem degradation caused by human impacts.

该项目旨在测试结构保留，即植物碎屑（原木、树皮、树叶）被截留并保留在河道内，是否可以抵消沿着河岸广泛清除植被造成的影响，这是澳大利亚和世界上普遍存在的问题。从理论上讲，保留是河流生态系统变化的主要环境驱动力，但这很少被测试，特别是在恢复的背景下。该项目的目的是表明，增加保留导致更高的物种多样性，从而为管理人员提供一个相对简单的方法来改善河流的环境条件，同时测试三个假设，纠正人类影响造成的生态系统退化。
