This Paper will cover the main achievements of Peter Reynolds between 1971 and his untimely death in 2001. During Peter's leadership of Butser Ancient Farm, he brought the practice of experimental archæology from the preserve of the enthusiastic amateur to a defined profession. In so much of the published work of today, Butser can claim early involvement. Peter's multi-disciplinary interests were prolific and numerous.

Without Peter's guidance, and with so many new challenges that need to be met in an ever-changing, multi-disciplinary "industry", long-term decisions as to which directions to pursue need to be addressed and answered within Peter's wider scope for the Farm:
- How to manage the changes, and continue with the vision?
- How to finance the endeavour?
- Who to operate the parts that make the whole?

Enlarging the farm from experiment in agriculture with established techniques, to encompass a detailed and continuous observatory, exploring the effects of environmental and climatic change with new techniques is both a legacy and a demanding challenge. This paper will examine these issues and will set the scene for the subsequent Papers.
