Perennial polycultures and forest gardens

Our primary focus Perennial polycultures, may include annuals as part of this, but no specific focus on annual polycultures as there is already plenty of research going into them.

Geographically: study perennial polycultures across the globe. Zones are likely to be defined by the group membership. Current core group has members from Europe, India, New Zealand and Central America. We would like to have at least one member form each major world region represented in the core group.
