This knowledge follows 5 years of personal experience and observation with moon phase harvesting in South Africa. This was following Andy Horns discovery of the technique while visiting Japan, where he met with some scientists studying this phenomenon, which is something that is part of their cultural heritage. We have since also made contact with moon phase foresters in Austria and Germany, where it is also part of their culture, as well as the worlds leading academic on the subject - Ernst Zuercher - a professor in wood science at the University of Zurich.
