Volunteers have helped clear heathland in Dorset, and taken free Christmas trees in the process.
The invasive Scots pines at Avon Heath Country Park need to be controlled to ensure it remains a perfect habitat for rare reptiles, insects and plants.
The conservation event was fully booked with 150 people picking up a festive tree for their efforts on Sunday.
Park ranger Marco Marsango said it was a "win-win" situation and urged people to book for next year.
"Heathlands are really unique - if we didn't have all volunteers' help, the scrub would return to woodlands. It is really appreciated," he said.
