There are two main ecological types where beech forest is found: Atlantic and continental. Those are<br />
also subdivi<strong>de</strong>d according to the pH of soil. Soil and plant associations of the different ecological<br />
types are presented in Table 1 (SIBW 2008) 9 .<br />

In the Walloon Region, the main interest in forest research is to observe phenology and phenotypic<br />
plasticity of the main broadleaved species (and notably beech), in or<strong>de</strong>r to assess consequences of<br />
potential climatic changes, as faced nowadays. This assessment will be achieved firstly by a state<br />
of the art of adaptation of current forest tree population, realized un<strong>de</strong>r greenhouse conditions.<br />
Secondly, evaluation of phenology will be conducted un<strong>de</strong>r different regional situations, consi<strong>de</strong>ring<br />
soil temperature at root level.<br />
As for the Flemish Region, on the one hand, research concerning beech focuses on the problems with<br />
natural regeneration and measures for its enhancement. On the other hand, new and more accurate<br />
tariff tables have been constructed.
