Azolla is an aquatic weed which can spread rapidly and choke dams and stock water troughs. It can reproduce asexually and under ideal conditions can double in size (area of water covered) in less than two weeks.

It thrives where surface water dams  collect nutrients, especially nitrogen and phosphorous from run off or stock access. The dispersable, grey clay soils of the Strzelecki  ranges  seem to suit the growth of azolla as the nutrients are carried into surface water storage dams on the soil particles, especially the clay. This project attempted to control the growth of azolla through two treatment activities.

We held a field day on December 1st 2017, to showcase the results of the treatments.

The azolla control project will be written up as a case study.  This will be published here when available.  In the interim the field day notes are available for download as a PDF file.

South Gippsland Landcare Network

We acknowledge the Traditional Owners of the land on which we work and meet. The South Gippsland Landcare Network stretches from Mt Best to Mt Lyal, and along the prom coast. It’s made up of 16 local groups working to preserve and protect the natural environment, while also enhancing the long-term sustainability of farming in this part of Victoria. We’re proud to work across both Bunurong and Gunaikurnai country, and to recognise the rich history embedded in this land we now share. As a network, we’re a diverse group – made up of primary producers, hobby farmers, tree changers, backyard gardeners and environmentalists of all sorts. This page is part of our community, so we welcome feedback and input from anyone who’s interested in having a voice here.
