 is in Claiborne County, Mississippi. References USGS map, name N3207.5-

Hydrology data - Twenty years of hydrologic data were analyzed for a 

 flow gauge on the U.S. Highway 80 bridge, 3.7 km east of Bovina, Missis- 

 sippi. A slope correction from gauge location to site was determined by 

 a water surface profile. 



General vegetation - Plant communities range from Taxodium disCichum- 

 Nyssa aquatica at lower elevations to Liquidambar styraciflua-Celtis 

 laevigata-Ulmus americana at higher elevations. Intermediate communi- 

 ties are dominated by Planera aquatica, Carya aquatica, Quercus lyrata, 

 and Fraxinus pennsylvanica. 



Soils and climate - Soils range from the Waverly series ( depress ional 

 phase) in lowest elevations to the Faylaya series at higher elevations. 

 Average annual rainfall for this area is 132 cm and the average growing 

 season is 226 days. 



Delineated zones - Zones 2, 3, and 4 were delineated for study. Zones 5 

 and 6 were not delineated due to major vegetation disturbance induced by 

 silvicultural and agricultural practices.
