Ecological intensification may reduce environmental externalities of
agriculture by harnessing biodiversity to benefit regulating ecosystem
services. However, to propose management options for the production of
such services, there is a need to understand the spatio-temporal dynamics
of net effects between ecosystem services and disservices provided by wild
organisms across taxonomic groups in relation to habitat and landscape
management. We studied the contribution of predatory vertebrates and
invertebrates (including both carnivores and seed herbivores) to
regulating ecosystem services and disservices in 16 cereal fields in
response to a local habitat contrast and a landscape complexity gradient.
From May to November 2016 we provided weed (predation reflects an
ecosystem service) and crop (predation reflects a disservice) seeds, as
well as pest (predation reflects an ecosystem service) and beneficial
(predation reflects a disservice) invertebrate prey to predators. Seed
predation was dominated by vertebrates, while vertebrates and
invertebrates contributed equally to predation of animal prey. Before
harvest, predation steadily increased from very low levels in May to high
levels in July independent of the resource type. After harvest, ecosystem
services declined more rapidly than disservices. The presence of adjacent
semi-natural grasslands promoted crop seed predation, but reduced pest
prey predation. Predation on beneficial prey decreased with increasing
proportions of semi-natural grassland in the landscape. Predatory
vertebrates and invertebrates provide important ecosystem services due to
the consumption of pests. However, beneficial invertebrates and crop seeds
were often consumed to a similar or even higher extent than harmful
invertebrates or weed seeds. Our results therefore raise concerns that
management options aimed at enhancing service providers may simultaneously
increase levels of disservices. By considering positive and negative
effects simultaneously, this study addresses an important knowledge gap
and highlights the importance of interactions between local management,
landscape composition and service and disservice provision across taxa and
over time. Considering trade-offs between ecosystem services and
disservices when evaluating the net effects of biodiversity conservation
measures on ecosystem service provision is crucial. Future
agri-environment schemes that offer payments for semi-natural habitats may
need to provide higher compensation for farmers in cases where net effects
are likely to be negative.
