Four schools in the Charters Towers region have pledged their support for the Great Barrier Reef by joining the Great Barrier Reef Marine Park Authority's (GBRMPA) Reef Guardian Schools Program.

Ravenswood State School, Charters Towers Central State School, Homestead State School and Pentland State School have joined more than 230 schools in the environmental program.  

GBRMPA education officer Carolyn Luder said the Reef Guardian students now have the opportunity to get involved in environmental projects that improve their local environment and the outlook for the Great Barrier Reef.

"The Reef Guardian Schools Program allows students to explore their catchment and work with the broader community to keep their region and the Reef clean," she said.

"It is fantastic that students and teachers in the Charters Towers region are studying the Great Barrier Reef and taking action to protect it for the future.  

"Some of the environmental projects the schools want to achieve through the program include starting composting, worm farming and vegetable gardens.

"The schools are also planning a trip to Reef HQ Aquarium next term to learn more about the Great Barrier Reef.

"As the future custodians of the Great Barrier Reef, these students have an important role to play in the future of the Reef."

The four schools join Charters Towers State High School, a Reef Guardian School since 2008.

The Reef Guardian Schools Program is a voluntary stewardship program that develops partnerships between schools and their communities to work towards a sustainable future for the Great Barrier Reef.

In its ninth year, this education program currently sees more than 60 000 students committed to the protection and conservation of the World Heritage listed Great Barrier Reef.
