More than 100 hectares of land near Hopetoun has been converted into a wildlife haven.
The partnership between South Coast NRM, the Water Corporation and Hopetoun Primary School saw about 4000 native trees, including endangered species, planted to rehabilitate the former Springdale Cattle Farm south of Hopetoun.
Water Corporation Regional manager Adrian Stewart said the planting project was an important part of a program to help protect drinking water catchment areas.
"Water Corporation purchased the site in 2010 with a view to gradually rehabilitate the area so we can better protect nearby water supply bores for the Hopetoun community," Mr Stewart said.
"This tied in perfectly with the goals of South Coast NRM and Hopetoun Primary School as students were studying the local environment.
Mr Stewart thanked everyone involved, especially the students, who braved the weather to participate.
South Coast NRM project officer Robyn Cail said they had worked with the corporation for five years to revegetate parts of the property and to restore natural linkages between the Jerdacuttup River and coastal wetlands.
"The rehabilitated corridor is an important haven for species like the endangered Carnaby's Black Cockatoo and Honey Possum, as well as restoring the banksia dominated 'Proteaceae Dominated Kwongkan Shrublands Threatened Ecological Community'," Mrs Cail said.
"We are already seeing flocks of over 300 Carnaby's Black Cockatoos feeding in the vegetation planted in 2014-15."
Hopetoun Primary School principal Brendan Murray said the project had been a great opportunity for students.
"We have been learning about native vegetation and planting local species at our school, so being included in a real-life larger, scale rehabilitation project that benefits our town was a great opportunity for students," Mr Murray said.
A camera trap to capture images of birds and animals in the newly rehabilitated area has also recently been installed.
This project was funded through the Australian Government's National Landcare Program.
