MaMA’s annually updated action maps show: 1) areas known or projected to be ready to search for lingering ash; and 2) areas needing more data and which MaMA project to use to collect it. The maps are initially created using EAB detection data to project when and where 95% mortality will be reached, but they are then refined and updated using data collected by MaMA projects.
