ABSTRACT
Dendroecology consists of the study of spatio-temporal relationships between woody plants and their habitat. It focuses on the influence of common environmental signals to all the trees of a community, on climate signals and their interactions with local ecological conditions and also on external large-scale disturbances. This science has grown rapidly over the last decades due to the emergence of new environmental issues (global warming, increased pressure on the environment). This article presents the principles of dendroecology, the methods implemented, and the recent developments in the discipline through examples of use in environmental sciences.

INTRODUCTION
Dendrochronology is a vast discipline that involves analyzing the chronologies of tree-ring widths. It is applied in a wide variety of fields (geology, anthropology, climatology) and currently encompasses all disciplines that make direct or indirect use of the "date" information contained in a tree-ring time series.
Dendroecology, derived from dendrochronology, refers to the study of spatio-temporal relationships between woody plants and their habitat. This discipline focuses on the influence of environmental signals common to all trees in a community: climatic signals and their interactions with local ecological conditions, as well as large-scale disturbances external to the forest community. It has diversified into several branches in recent years, in response to the emergence of new issues in earth and environmental sciences.
This article presents the basics of dendroecology (tree-ring formation and principles of the method, § 1 and 2 ), recent developments in the discipline and examples of its use in environmental sciences (paragraph 3 to
