PRAIRIE 



Vegetation 



The prairie ecosystem is known to many as 

 the tall grass or true prairie with the bluestems 

 constituting about 70 percent of the vegetation 

 and reaching heights of 5 to 6 feet. Large num- 

 bers of flowering forbs also exist but are 

 usually over-shadowed by the grasses. Most of 

 the plants are classified as warm-season plants. 

 Woody vegetation is rare with willow occasion- 

 ally occurring on the exceptionally moist areas 

 of the northern part of the ecosystem and 

 needleleaf evergreens and broadleaf deciduous 

 trees scattered in the southern part.

EASTERN FOREST 

 WHITE-RED-JACK PINE 



Vegetation 

 Forest in which 50 percent or more of the 

 stand is eastern white pine, red pine, or jack 

 pine, singly or in combination, represents the 

 white-red-jack pine ecosystem. Common asso- 

 ciates includes oaks, eastern hemlock, aspen, 

 birch, northern white cedar, and maple.

SPRUCE-FIR 



Vegetation

 stand is spruce or true fir, singly or in combi- 

 nation, characterize this ecosystem. Common 

 associates include northern white cedar, tama-

LONGLEAF-SLASHPINE 



Vegetation 



Forests in which 50 percent or more of the 

 stand is longleaf pine or slashpine, singly or 

 in combination, characterize this ecosystem. 

 Common associates include other southern 

 pines, oaks, and gum. 



On most sites, grasses either dominate the 

 understory or share dominance with shrubby 

 forms. East of the Apalachicola River, wire- 

 grasses are the main herbaceous species, where- 

 as bluestems provide most of the herbage in 

 the western section. Other important grasses 

 include panicgrass, paspalums, and dropseeds. 

 Gallberry, saw-palmetto, wax-myrtle, and shin- 

 ing sumac are prominent among the shrubs.
