Native bee communities are at risk of being negatively impacted by agricultural intensification, which threatens their role in crop pollination. Native bees, along with honey bees, are essential for pollination, but honey bee populations are declining due to diseases, pesticides, and other factors. Native bee communities can provide sufficient pollination services for crops like watermelon, especially on organic farms near natural habitats. However, on more intensively managed farms, native bee diversity and abundance decrease, leading to insufficient pollination. The study found that diversity is crucial for maintaining pollination services, as community composition varies year to year. Continued degradation of the agro-natural landscape could eliminate this "free" service, but conservation and restoration of bee habitats could offer viable alternatives to reduce reliance on managed honey bees. The research highlights the importance of biodiversity in maintaining ecosystem services and suggests that managing for bee diversity could benefit a wider range of crops and promote biodiversity conservation. Agricultural intensification reduces native bee diversity and abundance, leading to insufficient pollination services. The study also shows that native bee communities can provide sufficient pollination services for watermelon when managed properly, but this is not the case on more intensively managed farms. The findings suggest that ecosystem service arguments can align with biodiversity conservation efforts. The study emphasizes the need for conservation and restoration of bee habitats to maintain pollination services and reduce dependence on managed honey bees.Native bee communities are at risk of being negatively impacted by agricultural intensification, which threatens their role in crop pollination.
