Long Leaf Pine Occurrence The long leaf pine community, also known as a high pine community, occurs on well-drained soils and are well adapted to fires. They are found on the high ground in Florida where the soil can not contain the water and the sandy soil remains dry in between the rains. This community requires frequent, low-intensity fires, which occur every one to ten years, to open seed cones and allow the community to regenerate. Description The long leaf pine community is characterized by the presence of the long leaf pine trees and perennial grasses as ground cover. There are a few oaks present but most are burned out by the frequent fires because they can not adapt to fire as the pines have. The community also provides food for wildlife such as saw palmetto and oaks that provide sufficient food when they are fruiting. This community is completely dependent on fire and the pines have adapted well to surviving fire. Soils The soils found in the high pines are very dry coarse sandy coils. There is also sandy clay that is a dry soil that is rich in nutrients. The majority of soils are classified as entisols, which are excessively drained, highly permeable, and low and nutrients. The clay soi Continue...

The gopher tortoise, usually considered a sand hill species, frequently burrows in scrub but feeds in nearby herbaceous vegetation. They range from the pure white, excessively leached St. High-intensity fires that recur infrequently, perhaps once every 10 or even 100 years, depending on fuel accumulation and chance ignitions maintain scrub. Usually the density of the ground cover is inversely proportional to the density of the sand pines and shrubs. Reptiles Gopher Tortoise, eastern indigo snake, blue-tailed mole skink, short-tailed snake. The scrub jay, sand skink, mole skink are federally listed as threatened. DescriptionSoil Practically all scrub soils have little or no development and are derived from quartz sand. Fig 4 - Long leaf pine communityProblems There was a problem for sometime of humans cutting down the pines for commercial use and not replacing the supply after logging. Where fire is excluded andor the pines have been removed, oaks dominate. The low intensity fires found in this system are used to open up the seed cones and fertilize the ground to facilitate growth of the new seed. The color of a particular scrub soil reflects the length of time that the soil has supported scrub vegetation, as some soil characteristics are the result of biotic actions on the soil parent materials. Ground cover under the overstory of pine trees and shrubs is scattered and sometimes absent. Scrub, like many of Florida"tms ecosystems, is pyrogenic that is, its flora and fauna have developed adaptations to fire.
