I think the fruits (?and hence the seeds) are too small.  Also swamp oaks 
grow on very poor saline soil so the nutrients are pretty low.  Similarly 
River Oaks grow on recent alluvium which also may be poor.  There is some 
paper somewhere about them choosing those fruits with amongst their locally 
favoured Allocasuarinas that have a higher nutrient content.
