Arlesey Old Moat and Glebe Meadows are two nature reserves managed by the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire. They lie adjacent to the River Hiz and the East Coast Main Line, west of Arlesey itself. The Glebe Meadows were purchased, by raising funds, by Arlesey Conservation for Nature (ACORN)for the public to enjoy in perpetuity for quiet recreation and for wildlife. The Wildlife Trust agreed to hold the title of the land on their behalf. The Town Council also agreed to financially support the upkeep of the meadows. This project was to commemorate the new Millennium.
