This map is a 4 by 7 meter portion of the site. Each center represent a clump that grow within the concrete cracks. Tree dimension always record to their maximum are generating the drawing : base diameter, extention of leaves and height. Those dimention are not at the same scale that the location of centers so that the phenomenon is amplified.
This suggestive map localize the vegetation all around the site. Vegetation grows betwin the concrete slab and within the concrete cracks. Each intersection is a point that establish the present map, and by connecting all those points, I drew a time projection of the degradation.
