Relevés floristiques pour le suivi de la biodiversité végétale des écosystèmes forestiers : éléments de réflexion pour faire les bons choix

Abstract : Confronted with the various threats facing forest ecosystems (climate change, eutrophication, increased wood removals) managers of natural spaces feel a need to monitor biodiversity. The aim of this article is to provide guidance for survey planners to assist them in choosing the practical methods for conducting floristic recordings in a forest environment. It begins with a general description of the method (representativeness, exhaustivity, reproductibility, feasibility) and goes on to discuss various implementation options such as the overall surface area of the plots surveyed, the latters’ shape, factoring in the operator effect, seasonality, the relevance of considering the abundance and stratification of the species, with a view to fulfilling the monitoring objectives. The article does not propose a standard protocol and instead reports hands-on feedback from some ten or so years of studies of methodologies for floristic inventories steered by Cemagref at Nogent-sur-Vernisson (Loiret).
