Webinar: Probabilistic Tools for Addressing Uncertainty in Species Locations, Pesticide Use, and Associated Pesticide Use Limitation Areas in Endangered Species Act Assessments
Under the U.S. Environmental Protection Agency’s pesticide registration process, potential impacts on federally listed threatened and endangered species must be carefully evaluated. Yet traditional deterministic methods for analyzing geospatial overlap between listed species and pesticide use sites often overlook important spatial and temporal uncertainties in both species occurrence and pesticide application.
To address this gap, we developed the Automated Probabilistic Co-Occurrence Assessment Tool (APCOAT). Using multiple case studies, APCOAT demonstrates how integrating probability and uncertainty can strengthen both species conservation planning and regulatory decision-making. Its applications include supporting the development and evaluation of Pesticide Use Limitation Areas, incorporating probabilistic pesticide-use data into co-occurrence analyses, and improving assumptions used in aquatic exposure modeling.
In the webinar recording below, Environmental Modeler Jonnie Dunne explains how APCOAT is helping refine the data and methods used in Endangered Species Act assessments.
