NATURALIST'S GUIDE TO THE AMERICAS 



There is movement under way to set 

 aside about 25,000 acres of land of the 

 Camp Jackson tract at Columbia for a 

 national forest to be known as the Camp 

 Jackson National Forest Preserve. 

 This movement is sponsored by Dr. 

 A. C. Moore, of the University of South 

 Carolina, for many years an ardent 

 worker in the cause of reforestation 

 of South Carolina. To quote Dr. 

 Moore, "The purpose of this preserve 

 is to demonstrate proper forestry 

 methods applicable to the Sand Hill 

 Region of the state. This site lies 

 within the typical Sand Hill Region. 



3. Private Preserves. There are a 

 large number of private preserves from 

 several acres to 20,000 acres and over. 

 One of the largest preserves of this kind 

 is the Oketee Club at Ridgeland, S. C. 

 which contains 70,000 acres. These 

 preserves are maintained mainly for 

 sport but in spite of this fact they are 

 not to be utterly condemned as they 

 aid in keeping game from becoming 

 extinct in this state. It is claimed that 

 one may readily observe upon investiga- 

 tion the much greater abundance of 

 game in these preserves as compared 

 to the surrounding country.

1. Physiographic regions 



Five physiographic provinces are 

 represented in Georgia. These, begin- 

 ning at the coast, are (1) Coastal Plain; 

 (2) Piedmont Region; (3) Blue Ridge; 

 (4) Appalachian Valley; and (5) Cum- 

 berland Plateau. 



1. The Coastal Plain includes practi- 

 cally the entire southern half of the 

 state. Its inland boundary is marked 

 by the Fall Line, which extends in a 

 northeast-southwest direction from 

 Augusta, through Milledgeville and 

 Macon, to Columbus. In general, the 

 region is characterized by low and 

 gentle relief, though in its northern 



portion, in the vicinity of the Fall 

 Line, it displays considerable hilly and 

 broken topography. In correlation with 

 local differences in soil, altitude and 

 vicissitudes of geologic history, the 

 Coastal Plain exhibits a greater variety 

 of well defined minor physiographic 

 features than do any of the other physio- 

 graphic provinces. These minor sub- 

 divisions are: (o) Sea Islands, a series 

 of long, narrow sandy islands fringing 

 the coast; (b) Tidal Lagoons and 

 Marshes, a confused network of tidal 

 bays, lagoons and channels, with much 

 salt marsh, between the sea-islands and 

 the mainland; (c) Satilla Plain, a strip 

 of nearly level land about 20 to 35 mi. 

 wide parallel to the coast, with a general 

 elevation of from 15 to 25 ft. ; (d) Okefi- 

 nokee Plain, a higher plain, 20 to 40 

 mi. wide, roughly parallel to the last, 

 and with a general elevation of 60 to 

 100 ft.; (e) Southern Lime-sink Region, 

 a narrow strip of rather rugged topog- 

 raphy, parallel to and adjoining the 

 Florida border, and with an elevation 

 of 150 to 275 ft.; (/) AUamaha Upland, 

 an elevated tract of country, popularly 

 termed "the wire-grass country," from 

 40 to 75 mi. wide, in the south-central 

 part of the state, with a gently undulat- 

 ing topography and an altitude varying 

 between 125 and 470 ft.; {g) Dougherty 

 Plain, a tract of nearly level country 

 in the southwest corner of the State, a 

 lime-sink region, with an elevation from 

 125 to 450 ft.; (Ji) Red Hills, a narrow 

 tract of hilly country, a few miles south 

 of and parallel with the Fall Line, 

 characterized by the prevailing red 

 color of its soil, and having an elevation 

 from about 450 to 600 ft. ; (i) Sand Hills, 

 a very narrow belt of rolling or fiat- 

 topped hills, composed of pale gray sand 

 or gravel, adjoining the Fall Line, with 

 a maximum elevation of about 700 ft. 

 2. The Piedmont Region forms a wide 

 strip occupying practically the southern 

 two-thirds of the northern half of the 

 state. It is a section of crystalline 

 rocks with a broken or hilly topography. 

 Its elevation varies from about 400 ft. 

 along its southern edge to 1200 ft.
