摘要：This study utilized the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST)pollination model to investigate the impacts of using field data on ecosystem servicesmapping studies by using potential pollination services in Cumberland and Colchestercounties in Nova Scotia, Canada, as a case study. The model was run using two differentsources of data to inform the floral resource component of the model. First, the model wasrun driven by proxies and approximate values gathered from the literature. The seconditeration of the model utilized field-based data to generate floral resource abundance anddistribution values. Both models utilized honey bee-specific species preference data drawnfrom field observations and expert opinion in the literature. Results indicated an 8.1%increase in the amount of land designated as high quality when the model was informedby field-based data. Such discrepancies are important when considering the potential implications of ecosystem services mapping studies on policy. As a tool, ecosystem servicesmapping provides the opportunity to spatially evaluate the impact that different land-useplanning regimes could have on the supply and provision of various ecosystem services.However, as its popularity rises, it is important to keep in mind the accuracy and resolution ofthe data used to inform the modelling process.
