Data for: Critical habitat thresholds for effective pollinator conservation in agricultural landscapes

Biodiversity in human-dominated landscapes is declining, but evidence-based conservation targets to guide international policies for such landscapes are lacking. We present a framework for informing habitat conservation policies based on the enhancement of habitat quantity and quality and define thresholds of habitat quantity at which it becomes effective to also prioritize habitat quality. We applied this framework to pollinators, an important part of agroecosystem biodiversity, by synthesizing 59 studies from 19 countries. Given low habitat quality, hoverflies had the lowest threshold at 6% semi-natural habitat cover, followed by solitary bees (16%), bumble bees (18%), and butterflies (37%). These figures represent minimum habitat thresholds in agricultural landscapes, but when habitat quantity is restricted, marked increases in quality are required to reach similar outcomes., , , # Data for: Critical habitat thresholds for effective pollinator conservation in agricultural landscapes

We have included in the file \"Bishopetal_DataCollated_v04.xlsx\" eleven sheets of data that support the models and figures in our paper, and an R script detailing how the models were run and how the figures can be created with this data. These data include insect, flower, and landscape information as input data for the models, and the model predictions and coefficients as input data for the figures.
