PLATE 10 



Tidal Estuary Vegetation on Iriomote 



Upper: Pandanus or screw pine lines the established near shore, while a mangrove grows 



out over the tidal mud from the shore beyond. 

 Center: A valued timber tree, Heritiera littoralis, now rare, grows just beyond the mangrove 



trees along the tidal Urauchi River bank. 

 Lower: Tawada takes a specimen from a mangrove shrub, Avicennia marina, whose breathing 



roots rise fingerlike through the sand from long, radiating, buried roots.
