Appendix B. The number data samples for pollen and nectar.

Table B1. Over the five years and cumulating the 50 squares (or apiaries), 780 samples of pollen (totalling over 22 kg) were collected from 250 bee colonies, of which a sub sample of 450 was selected for botanical identification (based on a minimum value of 80 samples per year, evenly distributed in the season). An additional 67 samples obtained at the end of each honey flow (totalling approximately 4500 kg of honey) were extracted for botanical identification.
