Kuranui College students dug into horticulture last week when they planted 80 new flax plants along the Greytown-Woodside trail.
The trail is being developed from the end of Cotter St and the students were guided by Russell Calvert of the Greytown Trail Trust and science and horticulture teacher Ben Clausen.
Mr Clausen said: "It wasn't part of any of their classes, they just volunteered to do it - some of them are from my horticulture class and some are from my science class. They loved it - they loved getting outdoors."
The five students volunteered as part of the Kuranui College Environmental Awareness Programme. Mr Clausen said the school was looking forward to being involved in further community projects.
The school's ethos is "be the best you can be" and he said the staff placed an emphasis on giving each student their own individual educational plan and encouraged them to raise their own expectations about themselves.
"These students are doing something practical and they are gaining real experience."
Their efforts would provide the community with a real legacy, he said.
