Conclusions
We advocate that interaction-site networks can provide important
insights into the types of interactions between pollinators, plants and
the land-use in which they occur. This study also highlights the
importance of conserving non-bee pollinators in agroecosystems, given
many interactions recorded in this study involved flies, wasps and
beetles. Further, grass pollen (Poaceae) was a significant component of
the specialised interactions across multiple insect orders. The
identification of key plant-pollinator interactions that only occur
within certain land-use types suggests field-scale management may
provide the best outcomes for conserving or restoring plant-pollinator
interactions in modified landscapes. Incorporating species interactions
into conservation planning is an important next step in conserving
critical pollinator taxa and plants that sustain pollination ecosystem
services in agroecosystems.
