VEGETATION TYPES.

trucking*, and possibly the principal reason why it is not all under 
cultivation is that it is so much more expensive to clear than the 
high pine land, and not quite so easy to plow. The native plants 
do not seem to be put to any important use. Some of the hardwood 
timber would be valuable, but any one species grows so scattered 
that it might not pay yet to try to utilize it on a commercial scale. 
9. (CALCAREOUS) LOW HAMMOCKS. 
(figure 68 .) 
In the Ocala area these are almost confined to the Gulf hammock 
region, and correspond approximately with the “Parkwood” soils 
on the soil map. They are nearly always a little lower than the sur¬ 
rounding country, and damp, but hardly wet enough to be called 
swamps; although some of them have low wet spots with essentially 
the same kind of vegetation as the swamps to be described next. 
The soil consists of marl, clay, sand and humus in varying propor¬ 
tions, and is evidently pretty well supplied with lime, if not with 
potash. Soil animals have not been noticed, but conditions ought 
to be favorable for crawfish, if those occur so far south. 
The trees are mostly tall and straight, and make a dense shade. 
The humus probably seldom or never gets dry enough to burn, so 
that fire does not need to be reckoned with. The following plants 
have been noted in low hammocks in the months of February, March 
and May.
