Abstract

Blankets of aquatic weeds such as water hyacinth, forming over the top of freshwater wetlands are one of the major management issues facing floodplain wetlands in many parts of Australia. Recent projects that successfully removed floating weed mats from large coastal lagoons have resulted in dramatic improvements to water quality, fish diversity and productivity and public amenity. However, there is a need to reduce the costs of these harvesting operations. In a recent wetland rehabilitation project, we trialled a combination of three innovative methods to reduce the costs of initial weed removal and, potentially, long-term maintenance: bank-side herbicide application, aerial application of brine, and the use of modified small boats. The results successfully demonstrate simpler and more cost-effective means of removing large floating weed mats and improving water quality.
