More than 100 kilograms of rubbish was removed from a wood in Croxley Green after a clear up last month.
The clean-up was the first volunteer day on the woodland since the parish council acquired the land in 2017.
The items found during the clear up included a large knife. PCSO Steve Jacob was called in to make sure the weapon was removed safely. Police have confirmed the knife was not connected in any crimes.
Several residents came to help out on the day and were joined by parish councillors David Montage and Chris Mitchell.
Senior ranger James Townley said he was delighted.
He commented: “We are so grateful to all those who came along to help clean-up Weston Wood for the spring. It has made such a difference to the area and the woodland is now all set for us to get down to work.
We will be making some changes to the area to prevent people fly-tipping in the woods and opening up the natural so the area can be fully enjoyed by the people of Croxley Green.”
