African Bird Migration Corridor Vulnerability Assessment # African Bird Migration Corridor Vulnerability Assessment > **A reproducible spatial analysis project** that evaluates the conservation vulnerability of six African–Eurasian bird migration flyway corridors by integrating six ecological datasets into a single scored and classified output layer. --- ## Table of Contents 1.
