Reimagining Landscapes

Naturally reconnecting land, biodiversity and people

Pioneers in Landscape Restoration

Cassinia has been a leader in landscape restoration and biodiversity protection since 2004. We deliver projects which restore, reconnect and protect Australia’s natural systems; endeavouring to see all of Australia’s national parks reconnected through biodiversity-based revegetation projects. We also seek to incorporate conservation management into agricultural systems, creating landscapes which are both productive and ecologically resilient.

In the past 15 years we have delivered over 75 landscape-scale projects across four states, and in the process become Trust for Nature’s largest covenantor. This means that we have permanently protected almost 20,000 acres (8000 hectares) of our continent's unique environment - more than any other organisation in Victoria.

We exist to assist other businesses to develop projects which heal the planet, and collaboratively work to develop solutions in Carbon, Biodiversity Protection and Sustainable Agriculture.

Sustainable Agriculture
