RATING OF MA NAGEMENT TECHNIQUE FOR 

 PROD UCJ NC FL ORA AND FAUNA 



FLORA (Relative vegetative cover): 



SPECIAL NOTES 



Water salinities in these zones are as fol lows : 

 Fresh 0-2 ppt 



Intermediate 2-5 ppt 



Brackish 5-15 ppt 



Saline over 15 ppt 



2 

 Furbearer populations on Rockefeller are 

 presently at a low point in their cycle, but 

 this management technique has been success- 

 fully used in other areas, especially with 

 proper burning . 



This aplies only to Unit 9. 



All forced drainage units are of intermediate 

 salinities.
