International Day of Biodiversity on May 22 – a part of the United Nations’ awareness day calendar – is an annual event that aims to increase understanding and awareness of biodiversity issues. UNSW scientists are also striving to increase public awareness for crucial environmental issues by being passionate advocates for biodiversity – to ultimately create a sustainable future for our ecosystems and the diverse life that populates them.

This year’s International Day of Biodiversity is celebrated under the theme ‘Our Biodiversity, Our Food, Our Health’.

To help celebrate, we’ve selected a few highlights of UNSW research that aims to protect Earth’s biodiversity for future generations.

Huge feral-free haven ready for return of missing desert mammals

The Wild Deserts team have created a sanctuary for native Australian animals in the Sturt National Park that is completely free of feral animals

One of the largest rabbit-free areas in Australia has been created in Sturt National Park in far western NSW in a major project preparing to reintroduce locally extinct mammals such as the bilby to desert habitat. 

The Wild Deserts team, a partnership between UNSW, Ecological Horizons and the NSW government have created a 40-square-kilometre sanctuary for native Australian animals in the Sturt National Park that is completely free of feral animals such as rabbits, foxes and cats.

Towards zero hunger

A fish farming project is aiming to provide a sustainable source of food and income security for remote communities.

A UNSW scientist’s fish farming expertise is helping increase nutrition and provide a steady income, as well as a host of other benefits, for people in Papua New Guinea and Vietnam.

UNSW scientist Jes Sammut and his team initiated a fish farming research project which included teaching better aquaculture practises to remote communities. This includes how to dig ponds, manage water quality and care of fish populations.

Rivers running dry, algal blooms, more fish kills and towns running out of water will all continue to plague the next NSW government if it persists with the same, inadequate policies on water management.

UNSW’s Professor Richard Kingsford outlines what needs to be done to protect the Murray-Darling rivers and the communities that rely on them.

Bilbies vs. feral cats – a Hunger Games-style experiment conducted in a South Australian desert has produced fascinating results with important implications for the conservation of our endangered species.

Exposing vulnerable species like the bilby to an environment with predators before releasing them into the wild could help improve the species’ ultimate survival, new research by UNSW ecologists has shown.

Scientists enlist public to help restore viral seagrasses

Operation Posidonia aims to restore endangered seagrass meadows

Local beach goers are helping with the restoration of sea grasses by collecting live, green Posidonia shoots that wash ashore after storms.

Scientists are asking local communities to help restore endangered Posidonia seagrass meadows by collecting shoots that naturally become detached after large storms.

The project is encouraging local coastal communities to help restore ecologically and economically important seagrass meadows.
