Evaluating Biodiversity: The Example of French Guiana
French Guiana, “the French Amazon”, is situated close to the equator (between 3° and 5.5° latitude north). This region enjoys a warm and humid climate, with rather calm meteorological conditions (i.e., neither cyclones nor tropical storms). It is positioned on an extremely old gneiss and granite block (Proterozoic, about 2 billion years old, with a trace of Archeozoic more than 3 billion years old). Moreover, it is not subject to major telluric upheavals. So its ecological systems are not very often disturbed by extremely violent and widespread natural events. Nevertheless, we must remember that droughts have left a mark on its history and that, sporadically, these droughts have had consequences. We find in particular traces of paleo-fires in the forest, and the savannah is often burned.
