CLLMM drought recovery videos

This collection of videos helps us remember the drought of 2006-10 and what the community and government did in the Coorong, Lower Lakes and Murray Mouth (CLLMM) region to recover from it.

Through these videos, the information and knowledge gathered in 2010-2016 during the $137 million CLLMM Recovery Project is accessible for years to come.

Stories of recovery

The CLLMM Project helped bring plants and animals back. The large scale Vegetation Program saw unprecedented levels of plants being grown and planted throughout the region.

Acid sulfate soils

The soils of the Lower Lakes were nearly irreversibly acidified. Watch what was done to ensure soils remained healthy.

The Acid Sulfate Soils Program:

• used bioremediation – planting vegetation by, for example, seeding lakebeds to increase organic matter – to reverse the acidity
• neutralised acidified soil and water over 20,000 hectares through limestone dosing.

Ecological monitoring

The Coorong and Lower Lakes are an internationally recognised wetland site under the Ramsar Convention. It was important to accurately define which plants and animals should be thriving and where.

Ecological monitoring in the CLLMM resulted in:

• more than 35,000 records generated for the SA species database
• a baseline from which to track recovery, such as defining the water levels and water quality needed to protect key species
• an understanding of how and why the site is internationally important, and what we need to do to keep it that way.

This infographic highlights some of the key achievements of the program.

Pests and weeds

Pests and weeds don’t have natural predators so it’s up to us to control them and minimise their impacts on native species.

As part of the pest and weed program in the CLLMM region:

• 10 priority pest and weed species and 24 priority habitats were identified and treated
• pests and weeds were controlled over more than 6000 hectares
• key invasion sites were spatially mapped and pests were removed from significant habitats, roadsides, revegetation areas and shack sites in conservation areas
• the presence of priority pest and weed species were mapped and monitored to ensure control measures were working.
