In 1989, the first Sarsen Trail & Neolithic Marathon was held, raising £21,500 which was used to buy Morgan's Hill nature reserve.

As of 2022, its 60th year, the trust owns and manages over 40 nature reserves, including three farming operations, and has over 20,000 members.

The trust undertakes a wide variety of projects to engage local residents with its work, and to develop an understanding and love for the natural environment.

It is also working with the charity Help for Heroes, aiding injured service personnel to recover through carrying out conservation tasks at Tedworth House.
