2. Tall grassland with a shrub 



layer (shrub canopy cover 

 is 11 to 25 percent) (e.g., 

 the transition from the 

 true tall grassland prairie 

 and shrub land; a shrub

 unknown for U.S.)

deciduous 



Tall subtropical grassland 

 with open groves of palms 



B. Medium tall grassland 



(grasses and forbs over 

 0.5 to 1 m tall) 



4. Tall grassland without a 



woody layer (tree or shrub 

 canopy cover is to 10 

 percent) (e.g., tall grass 

 prairie of eastern Kansas) 



1. Medium tall grassland with 

 a tree layer (tree canopy 

 cover is 11 to 25 percent) 

 (as in subclass tall grass-

Medium tall grassland with 

 a shrub layer (shrub canopy 

 cover is 11 to 25 percent) 

 (as in subclass medium 

 tall grassland— the shrub 

 savannah)
