Stability of pollination services decreases with isolation from natural areas despite honey bee visits

Sustainable agricultural landscapes by definition provide high magnitude and stability of ecosystem services, biodiversity and crop productivity. However, few studies have considered landscape effects on the stability of ecosystem services. We tested whether isolation from florally diverse natural and semi-natural areas reduces the spatial and temporal stability of flower-visitor richness and pollination services in crop fields. We synthesised data from 29 studies with contrasting biomes, crop species and pollinator communities. Stability of flower-visitor richness, visitation rate [all insects except honey bees] and fruit set all decreased with distance from natural areas. At 1km from adjacent natural areas, spatial stability decreased by 25, 16 and 9 percent for richness, visitation and fruit set, respectively, while temporal stability decreased by 39 percent for richness and 13 percent for visitation. Mean richness, visitation and fruit set also decreased with isolation, by 34, 27 and 16 percent at 1km respectively. In contrast, honey bee visitation did not change with isolation and represented less than 25 percent of crop visits in 21 studies. Therefore, wild pollinators are relevant for crop productivity and stability even when honey bees are abundant. Policies to preserve and restore natural areas in agricultural landscapes should enhance levels and reliability of pollination services.
