In Sydney Harbour, certainly upriver, nearly 100% of the natural shoreline has been transformed to artificial shorelines. This remarkable restoration project seeks to bring natural shoreline and marine biodiversity back

Sea-urchins have over-adapted to urbanisation and their proliferation is causing urchin 'barrens', areas devoid of kelp and seaweed. A project is tackling this by removing urchins, enabling areas of kelp forest to be restored

The marine life of the Sydney Harbour got to a low in the 1960s and 1970s, but we've seen an improvement in the last 50 years, with a growing abundance of marine life in the harbour.

This unique marine restoration project is working to restore Sydney Harbour's beautiful seagrass meadows - crucial habitat for marine biodiversity

An incredible project in the heart of Sydney harbour aims to save one of the world's two endangered species of Seahorse - the beautiful, tiny, White's seahorse.

In and around Sydney Harbour, we have over 600 unique species of fish. To put that in context, that's the same biodiversity as the entirety of the European continent.

Project restore is a leader globally in moving beyond habitat-by-habitat marine restoration to provide an example of how multi-habitat restoration can be conducted at seascape scale.

What is now Sydney Harbour, 12,000 years ago was a river valley that was drowned. Water flooded in and the sea level rose 120 metres

Crayweeds are a type of seaweed in Sydney harbour and surrounds that are like ecological foundations in our marine environment. If you take that away, everything else goes. If you bring that back, then everything else comes back with it. That is the goal of operation Crayweed.
