(l.'^-S.O km or O.^'-l.Q mi wide). The 

 forested flood plain broadens along the 

 lower river (up to 7 km or 11.3 mi wide), 

 with most of the flood-plain wetlands 

 located in the lower delta (H. M. Leitman 

 et al. 1982). The forested flood plain of 

 the Apalachicola basin is the largest in 

 Florida (450 km?, 173 mi?; Wharton et al . 

 1977), and 60 of the 211 tree species in 

 north Florida are found there (Table 4). 



The predominant soecies in terms of cover 

 include water tupelo, ogeechee tupelo, 

 baldcypress, Carolina ash, swamp tupelo, 

 sweetgum, and overcuo oak. These soecies 

 are typical of southeastern alluvial flood 

 plains and occur in such areas partially 

 because of their adaptive response to 

 restricted availability of oxygen in 

 saturated and inundated soils. Despite 

 continuous logging for over a century, the
