Natural Resources Kangaroo Island

Nationally Threatened Plant Project

Habitat loss, fragmentation and an absence of fire are leading to the decline of plant communities that support 25 regionally, nationally or state listed threatened plant species in eastern Kangaroo Island. Without active conservation efforts their decline and extinction will be inevitable.

By reinstating quality habitat through large scale plantings the survival of threatened plants becomes less reliant on small, unsustainable patches of remnant vegetation. During the 2013 Kangaroo Island Planting Festival, 319 volunteers planted 57,000 seedlings of 130 species, including three nationally threatened species, across 25 ha. Since 2008, 1,900 volunteers have planted 400,000 tubestock to re-establish 180 ha of diverse threatened plant habitat.

The role of fire in maintaining ecosystem diversity and health has also been investigated. Much of the landscape of eastern Kangaroo Island has not been burnt for at least 30 years.

Since 2008, more than 150 people have been involved in the completion of 42 prescribed burns to stimulate regeneration of senescent plant communities. Outcomes of this project to date include the regeneration of a diverse range of plants (including endemic and threatened species) and a substantial increase in knowledge of the effects of fire intensity and season on the regeneration response.

The prescribed burn program has been an excellent training opportunity, providing a large number of fire fighters with invaluable field based fire management knowledge and experience. It represents a unique example of what is possible when a large number of stakeholders work together to achieve a landscape scale conservation outcome.
