构建了佛罗里达中北部旱生植物群落的演替方案。还确定了继承率。有人建议，蓝杰克橡树沙丘，土耳其橡树沙丘，和旱吊床社区正在改变对一种形式的梅西奇吊床。虽然灌木在物种组成上没有变化，但个别树木的数量和大小都在增长，群落可能会成为一个旱生吊床。的演替方案得出的一组生态系统下人工灭火，因此不一定是真实的不受干扰的条件下，自然火起着重要的作用。随着不受人类管理实践影响的土地数量的减少，本研究中观察到的演替模式将成为主导形式。
A successional scheme for the xeric plant communities of north-central Florida was constructed. Rates of succession were also determined. It is proposed that the bluejack oak sandhill, turkey oak sandhill, and xeric hammock communities are changing toward a form of mesic hammock. Although the scrub was not changing in species composition, the individual trees were growing in number and size and the community may possibly become a xeric hammock. The successional scheme was derived for a group of ecosystems under maninduced fire suppression and thus is not necessarily true for undisturbed conditions in which natural fires play an important role. As the amount of land uninfluenced by man's management practices decreases, successional patterns as observed in this study will become the predominant forms.
