SHORTLEAF PINE. 
Shortleaf pine is of too rare occurrence to be a factor in the com- 
mercial forest. With the exception of spruce pine, it is the pine 
least represented on the tract. It occurs for the most part as seat 
tered individuals over restricted areas, occasionally forming 12 to 20_ 
per cent of the stands. It is found in mixture with either longleaf or 
loblolly pine, but more frequently with the latter. 
Its soil and moisture requirements are between those of the two 
pines with which it associates; it grows on the more moist longleaf 
lands and drier loblolly lands, preferring a fresh loam. 
It is a uniformly small tree, seldom exceeding 2 feet in diameter, 
but reaching a height of 100 feet. It develops a long, clear bole, with 
a small, irregular-shaped crown. 
Shortleaf pine is not tolerant. It will stand some shade in youth, 
but soon demands full sunlight. It ranks with loblolly in this respect. 
Reproduction is generally good. Trees of this species left after 
lumbering are surrounded with seedlings. Since it is in nearly all 
respects a less desirable tree than loblolly, reproduction should not be 
encouraged. 
In growth this species is slower than loblolly and faster than long- 
leat pine. 
POND PINE. 
Pond pine occurs on wet lands, swamps, savannahs, bays, and bottom- 
lands, but reaches merchantable size only on the bottomlands. It is 
the tree most largely represented on waste lands, such as savannahs 
and bays. 
In the bottoms it occurs in mixture with loblolly pine, maple, ash, 
red, white, and black oaks; in the deep swamps with cypress and black 
gum. In poor situations it sometimes occurs in almost pure stands. 
Like the loblolly pine it will grow where there is standing water 
during the greater part of the year, but it develops best on the rich,
