In secondary succession, calcium, magnesium and pH decreased with succession.
Organic carbon increased with succession. The C:N ratio increased with succession.
N03-N, NH4-N, K and acid soluble P04-P showed no consistent trends.


PLAN OF STUDY

 To answer the question, "Do self-organizational processes of forested wetland
communities result in measurable trajectories?" field measurements of vegetation and
soils on a chronosequence of sites in the central Florida phosphate-mining district were
collected. The selection of a chronosequence of research sites ranging in age from 0.5 to
19 years old facilitated the detection of changes in parameters with time. Trajectories
were developed for each of the vegetation structural categories and soil parameters
identified in Table 1.
