The geomorphology and dynamics of the atmosphere are two elements which
determine the diversity of the bioclimates of the Lesser Antilles. These are
usually associated with specific forest types: seasonal evergreen rainforests
with their subtypes and facies, tropical sub-montane rain forests and tropical
montane rain forests. Originally, these forests had many plant species in a
plurality of combinations and reflecting the multiplicity of biotopes. Human
activities varying in intensity and frequency have, over the centuries caused a
reduction of multiple forms in the ecosystem. The phytocenotic canvas of today
derives from this phenomenon and is a good example for the study of various
structural, architectural and functional features. To decrypt the main
spatio-temporal characteristics of plant cover, we used data from the
scientific literature specific to this region and from some of our field
surveys. It was therefore possible to highlight the different levels of integration
(of complexity) of the scale on the site of the installation and expansion of
plant species (microsystemic) individuals in various places (macrosystemic):
the latter inmesosystems. We have also been able to decrypt the biological
traits of different groups of taxa involved in all stages of plant succession.
