Young pupils in Helensburgh planted more than 300 trees in a local woodland in a bid to look after their environment.
Primary 4 children at Hermitage Primary received their John Muir Discovery Award for their fortnightly visits to the town's Castle Wood.
The children spent 1,425 hours in the woods carrying out important conservation work by carrying out a tree investigation of the existing trees and planted over 300 new trees with help from the Woodland Trust.
They also took part in regular litter picking and collected up to three bags full of rubbish each week.
Joanne Le Good, teacher at Hermitage Primary told the Advertiser: "When we first started going to the woods the adults took the lead in the activities.
"However as the children became more and more familiar with the woods, they took ownership of of their learning.
"Gradually they started leading the sessions, which has been so empowering for them.
"It’s been lovely to see the children working together and enjoying the outdoors with their peers."
The ideas on how to look after their woodland were driven by the pupils deciding what and how they wanted to learn about conservation work, ways they could use the woods to enhance their learning, and how they could encourage other people and creatures into the space.
Their determination even saw the children learn how to use Laplander saws and carve wood to builds dens and other creations.
The award, which is run by the John Muir Trust, encourages people to connect, enjoy and care for wild places.
However, as the charity faces financial constraints, they are planning to launch a redesigned award next year, and thus are currently unable to accept new proposal forms.
Though John Muir himself didn't have a specific link to Helensburgh, he is immortalised in the town through a sculpture on the seafront marking the western end of the John Muir Way, which stretches for 134 miles from the north Clyde coast to Muir's birthplace in Dunbar, East Lothian.
The town was chosen for the western end of the route because Muir and his family, who emigrated from Scotland to the United States in 1849, might have looked out on the Burgh as the ship that would carry them across the Atlantic cast off from Greenock at the start of its voyage.
The full route, which was opened on the centenary of Muir's death, takes between nine and 11 days on average to complete - though more than a handful of super-fit athletes have covered some or all of the route in considerably less time, often raising money for charity, since the walk was opened.
The Way was opened in 2014 and its 10th birthday was celebrated at a series of events earlier this year.
Muir went on to carve out a name for himself as a world-renowned naturalist and conservationist, and his work in the United States led to his becoming known as 'The Father of the National Parks'.
