Buffer zones for biodiversity of plants and arthropods: is there a compromise on width?

Fig. 3.22. Biodiversity among Coleopterans. Estimated average number (per 10 sweeps) of species of Chrysomelidae (leaf beetles) and Curculionidea (weevils). Species (Left) and Shannon’s index (right) at each of the three sampling periods. Only the herbivorous families Chrysomelidae and Curculionidea were included. Period 1: After herbicide application (May). Period 2: After first insecticide application (June). Period 3: After second insecticide application (July) (In Appendix D Tables D.16-19 the 95% Confidence limits and significant differences at each distance are presented).
