Sustainable Development in Sydney
With the support of our local project partner Operation Crayweed, SeaTrees is conducting the restoration of 43,056 sq-ft (4,000 sq-m) of kelp within two separate project sites along the South Bondi subtidal rocky reef in Sydney, New South Wales, Australia.
Crayweed is among the most important ecosystems on the planet, providing critical food and habitat for hundreds of species. These vast underwater forests support coastal food webs, sequester immense amounts of atmospheric carbon, produce oxygen for marine life, and support unique coastal biodiversity, which is not supported by any other seaweed species.
Sustainable Development Goals addressed by the project
SeaTrees evaluates this project annually to measure its impact on all relevant Sustainable Development Goals. The Sydney project addresses six SDGs. Read below for more details.
The Sydney crayweed forests support economically important species targetted by commercial and recreational fishers, including abalone and lobster. By restoring crayweed forests, this project enhances the habitat for these species, with a potential link to food security.
This project engages with younger members of the community through education activities in local schools, including Balgowlah, Clovelly and Avalon Public Schools in Sydney, as well as during National Science Week.
Operation Crayweed and the Sydney Institute of Marine Science employ several women who are key to the research and conservation efforts of this project. Operation Crayweed also runs community engagement and education activities that empower women and girls in the local areas.
Though not directly, a key aspect of urban resilience and sustainability is the maintenance and enhancement of native biodiversity and habitat, which this project implements by restoring crayweed forests along Sydney’s coastline, the largest city in Australia.
Kelp forests play an important role in sequestering CO2 around the world. Globally, kelp forests sequester as much CO2 as the world's mangrove forests. Additionally, the Sydney kelp forests are among the most important ecosystems on the planet, providing critical food and habitat for hundreds of species.
A key scientific aspect of this project is that we use our understanding of the genetic makeup of populations to restore in order to enhance the genetic diversity (and thus potential resilience) of restored populations. Our current scientific research aims to determine which genotypes/populations of crayweed (and their microbiomes) can be used to build resilience of these forests into the future.
These vast underwater forests support coastal food webs, sequester immense amounts of atmospheric carbon, produce oxygen for marine life, and support unique coastal biodiversity, which is not supported by any other seaweed species.
