SPILLEST Spillover Likelihood Tool

SPILLEST, spillover likelihood tool, is a conceptual model developed to estimate the likelihood of spillover for existing and proposed marine protected areas (MPA). The tool integrates the potential environmental, social and economic factors that contribute to the occurrence, magnitude and detectability of spillover. Based on literature and meta-analysis, SPILLEST can be applied for any relevant species and allows users to explore various MPA configurations and their contribution to spillover. SPILLEST was tested and validated in several MPA case studies and was found to largely conform with expectations of the relevant experts.
