Can forests help pollinators? The answer is obviously yes, but a recent paper published in the Journal of Animal Ecology, also assessed how, particularly with regard to wild bees.

Des chercheurs ont étudié l'influence des conditions de restauration des forêts sur la diversité des abeilles sauvages en Chine.

The study analyzed 8,341 bee individuals representing 79 species of wild bees and assessed the effects of tree species richness, canopy cover, understorey vegetation, and microclimatic conditions. Results show that canopy cover reduced taxonomic diversity. However, when understorey vegetation cover was considered, these patterns reversed, highlighting the mediating role of vegetation structure. Tree species richness indirectly influenced bee diversity through changes in the understorey microenvironment.

The findings reveal complex interactions between forest structure and pollinator communities, offering guidance for restoration strategies that better support wild bee biodiversity and pollination services.
