The project will rely on stock from seed banks that Greening Australia began expanding in February, with a $5 million top-up grant from the Morrison government’s wildlife recovery funding.
The project will begin on Tuesday with the planting of 20,000 trees at Arthursleigh in the NSW Southern Highlands on land owned by the University of Sydney, and five million trees will be planted per year across Victoria, New South Wales, Western Australia, South Australia and Tasmania to reach a total of 25 million trees by 2025.
The project will create and preserve habitat and habitat corridors for endangered species affected by the bushfires, with a focus on species such as Eucalyptus punctata and Eucalyptus melliodora trees to increase access to food supply for the koala and Regent honeyeater, as well as she-oak trees, an important food supply for the threatened glossy black cockatoo.
Other endangered species such as the sandhill dunnart, malleefowl, honey possum and black-gloved wallaby are also expected to benefit from increased habitat.
Under the Greening Australia program, private landholders with areas of high-priority landscape and habitat are identified and commercial arrangements are made so farmers can access funding to care for and preserve the new habitat.
According to Greening Australia chief executive Brendan Foran the project could create as many as 890 regional jobs over the next five years, engaging up to 150 Indigenous and non-Indigenous business subcontractors, seed suppliers and nurseries.
Mr Foran said, since he joined Greening Australia in 2010, the organisation had planted around 60 million trees, but that group was determined to scale up its operations to plant 500 million trees across 330,000 hectares by 2030.
