The present vegetation types provide baselines for studies of 
vegetation development. The similarities and differences among the 
types in each major category may reflect environmental character- 
istics or recent histories, but further research is required to 
establish correlations. Most of the Center has been abandoned from 
cultivation within the past 70 years or less, and the vegetation in 
these areas is still immature and changing considerably. The older 
hardwood forests appear to be mature and relatively stable. 
The two vegetation maps of the Center (Figures 4 and 5) are based 
on 28 vegetation types, which are listed in the legends of the maps. 
Details of the types are given in Table I, which includes lists of 
the more abundant plants and provides a basis for comparing the 
vegetation on Java Farm and Ivy Neck. There is less overlap between 
the vegetation types of the two areas than might be expected, 
probably in part because of the more level topography and poorer 
drainage at Ivy Neck, and in part because of differences in recent 
historical land use. No vegetation map of Corn Island has been prepared. 
The remainder of this report will explain the structure of the 
checklist and of its artificial keys. The ecological annotations 
which show the relationship of each species to its vegetation pattern 
will also be described. 
Table I follows.
