More than 45,000 native seeds and seedlings are being planted across the Wheatbelt as part of a partnership between Greening Australia and Officeworks.
The Restoring Australia initiative has extended to Western Australia for the first time, with the seedlings being planted at Avondale Park and Bush Hill Farm in Beverley.
Launched in August 2017, Restoring Australia sees two trees planted for every one used, based on the weight of paper based products that customers buy at Officeworks.
Greening Australia project officer David Collins said the aim of the planting across the Wheatbelt is to revegetate the area, following extensive unsustainable farming that has caused severe damage over time.
Mr Collins said restoration will also create a suitable habitats for endangered species including three types of Black Cockatoo - Carnaby's Cockatoo, Baudin's Cockatoo and the Forest Red-Tailed Cockatoo.
Avondale Park is managed by Oral McQuire's family organisation, Yaraguia Enterprises Inc - a group of traditional Ballardong Noongar landholders.
Mr McQuire applied for several properties through the Indigenous Land Corporation and it was then that he started considering a farm with the idea of healing the land through revegetation and rehabilitation.
His 2100-acre property was once bushland, but has since been used for extensive unsustainable grazing and grain and sheep farming, causing damage and loss of biodiversity.
"We started planting seeds in 2008 and have incorporated Indigenous land management practices on the ground, all with the aim of restoring the land, establishing native plants and creating a substantial habitat for species including the endangered Carnaby's Black Cockatoo," Mr McQuire said.
"I'm eager to get work underway this planting season as part of Restoring Australia, to take steps to reach our goal of one million trees planted, while creating natural ecosystems.
"Avondale Park has a cultural significance to my family and the Noongar people.
"In the first year of taking possession of the land, my brothers and I found several sacred heritage sites.
"This project will have a huge impact on the Aboriginal community - I will continue to run cultural training on site, focused on healing our land so that country can heal us.
"I'd like to create a cultural sanctuary, where Noongar people are engaged and connected to the land, the same way I have had my own journey spiritually reconnecting to country and coming home.
Officeworks' general manager corporate affairs Alexandra Staley said thanks to customers, the initiative will have planted around 569,200 seeds and seedings by the end of 2019.
