Natural habitat does not mediate vertebrate seed predation as an ecosystem dis-service to agriculture

1. Spillover of beneficial organisms from natural habitats to croplands can improve agro-ecosystem services, but wildlife can also negatively influence agricultural production. When managing agricultural landscapes to conserve biodiversity, we need to understand if the availability of natural habitats increases ecosystem dis-services such as vertebrate seed predation to avoid risking higher costs than benefits. 2. We studied whether vertebrates and their impact in crop seed predation are related to the percentage of natural (Chaparral) and semi-natural habitat (planted forest with native and exotic trees) in an agricultural landscape of Israel. We selected 20 almond and 20 sunflower study sites within a landscape with varying percentages of natural (0–61%) and semi-natural (0–70%) habitats within a 1000-m radius of their surroundings. We observed birds, trapped rodents (in almond), counted seeds and noted feeding marks to obtain seed predation rates, at each site. Within the almond crop...
