 propriate statistical evaluation. The actual study design should be devel-

ENDANGERED SPECIES 



Rare or endangered species are a special concern, but none have yet 

 been found in the study area. Ayensu and De Filipps (1978) were used as 

 authorities for this determination. 



Using Du Mond's definition of rareness, some species such as Cystopteris 

 ^"^^g^'TS could be considered rare, but no plant species yet identified in the 

 study area is officially rare or endangered.
