The distribution of vegetation in Iron Age Philistine sites. The size of the circles reflects the total number of plant species identified at Iron Age sites. The red color indicates that they appeared only in Philistine sites from the Iron Age. The green color indicates that they only appeared on the sites of non-Philistine peoples from that period. The blue color indicates that both types of vegetation existed on the site at the same time. MAP PRODUCED BY M. FRUMIN USING ARCGIS FOR DESKTOP (ARCMAP 10.1), ESRI
