Extended Data Figure 5. Historical timeline in changes in nectar resources and flower-visiting insects in Great Britain.

Historical periods with the greatest negative changes in nectar resources and flower-visiting insects are indicated in red, those with intermediate changes are in orange and those with the lowest (or even reversing) changes are in green. Main historical trends from this study (Baude et al.) are presented in regard to those described in Carvalheiro et al. 2014¹⁰ and Ollerton et al. 2014⁹ studies. The white chevron indicates a provisional extinction rate that needs to be confirmed on a 20 year period of time (see supplementary materials from Ollerton et al. 2014⁹).
