Thousands of trees are being planted this week to celebrate Schools Tree Day in Tasmania.
Senator Christine Milne showed her green thumb by joining a team of eager tree planters at Blackman's Bay Primary School in the state's south.
She said it was heartening to see our schools take part in National Schools Tree Day.
"It's great to look around and see our schools, but more importantly the next generation of Tasmanians, viewing trees as an important part of their learning environment."
"I can't think of a better way for schoolchildren to learn the importance of trees, of forests and habitat for our wonderful nature, birds and animals than growing together with the young trees they've planted."
"These trees are no more decorations than the wonderful drawings and paintings hanging in every classroom. They're important symbols of learning. They're ecosystems, each of them biological, living classrooms."
Senator Milne was given a guided tour of new school facilities currently under construction and congratulated the staff and students for using sustainable practices.
"Building sustainable classrooms is only half the battle; what's particularly satisfying here is knowing that staff and students will teach, learn and use these buildings in ways which impact as little as possible on the environment."
Each year 300,000 volunteers plant for National Tree Day at about 3500 sites in Australia.
Schools Tree Day is on Friday 31 July.
National Tree Day is on Sunday 2 August.
