Tiny field-edge strips changed where pollinator models placed habitat
WHAT THE EVIDENCE SAYS
Fine-resolution (10-meter) species-distribution models incorporated herbaceous linear landscape elements as cover or distance covariates. Compared with models lacking these features, inclusion improved predictions and reduced overprediction in fields and underprediction at edges; improvements were evaluated against independently collected field records as well as withheld training data.
WHY IT MATTERS / OUR READ
Restoration opportunity maps need to capture narrow field margins and ditches, not just broad land-cover classes; independent field validation matters when models guide scarce conservation funds.
CAVEATS / UNCERTAINTY
Model improvement is not proof that newly adding a strip will cause equivalent abundance gains. Transferability from three Dutch landscapes to other crops, climates or taxa remains to be tested.

Dutch bee and hoverfly models improved when linear habitat elements were mapped instead of being averaged into cropland.
