Long term dynamics of oak ecosystems : assessment of the role of root pathogens and environmental constraints as interacting decline inducing factors

Obiettivo

The main objective is to improve our understanding of the complex processes governing long term dynamics of oak ecosystems, that may sometimes derive in severe and recurrent decline episodes. We will concentrate on the role of root pathogens in interaction with environmental constraints as potential decline inducing factors. As a result of this effort, comprehensive conclusions will contribute to improved oak forest management that enable to escape or to contain decline hazard. Intermediate objectives are:
1- To develop a retrospective analysis of growth and water use in healthy and declining trees;
2- To broaden evidence on occurrence and distribution of Phytophthora species and related fine root-damaging fungi in oak stands, and to assess their pathogenicity on oak trees;
3- To understand how fine root disease may increase susceptibility of oaks to decline and how Root-Rot pathogens may promote long term damage;
4- To draw evidence on conditions under which decline scenarii as sketched from the research results could develop in different stands.

The research proposed will interact between two groups of disciplines, ecophysiology and pathology. It will be conduced in four KU. countries (France, Germany, Italy and the UK). It involves fourteen teams grouped in five contractor partners. Studying water efficiency will make possible to know for oaks, how long time is required for decline to develop and if some trees are predisposed to it, particularly trees infected by root and butt rot basidiomycetes. Interaction between root pathogens and oak physiology will be studied in forest conditions on mature trees and in experimentally controlled conditions on young trees as well. Two groups of pathogens will be considered, those infecting big roots (i.e. root and butt rot basidiomycetes) and those infecting fine roots (Pythiacious fungi). A special attention will be paid to water status of oaks in presence of root pathogens and nitrogen nutrition will be also considered. Water status of trees will be considered as predisposing factor and as a consequence of root infection. The proposal aims also at clarify the possible impact of Pythiacious fungi, particularly Phytophthora species on oak. This will be obtained in an extensive survey of oak ecosystems for knowing distribution of the fungi in soils, then investigating pathogenicity. Many methods and techniques that we will develop in the proposal will be common for making the results comparable. Results obtained will conduce to define comprehensive scenarii of oak decline and to recommend some types of management better adapted to contain decline hazards.
