Conservationists created 'bee hotels' and planted wild flowers in North Town Moor on Saturday.
Around 20 Make Space for Life (MSFL), and Rotary Club of Maidenhead Bridge volunteers carried out a range of conservation jobs in the Moor before enjoying a 'Big Lunch' picnic.
Children also got to play games and activities at the picnic.
The Big Lunch is the brainchild of the Eden Project and brings together communities across the country for a bite to eat and a few hours of friendship.
Maidenhead Bridge Rotary Club president Lisa Hunter said: "This is just a great opportunity to celebrate the conservation work that has taken place on North Town Moor."
Jonathan Howe, chairman of the MSFL group, said: "We've made such a big difference to the area.
"The work has brought people together who wouldn't otherwise have known each other and we've had a lot of fun in the process."
