Health check not very good
A forest can be managed over several decades if we want to do well. Jean-Christophe Hamelin, municipal councilor responsible for health prevention, the sanitary environment and the communal forest, gives us the state of health of the Thionville communal forest. And the least we can say is that it is not very good.

700 ha of woods
Particularly affected, the Grand Est region suffers from climate change, with the increase in temperatures, heat waves and the drying out of soils during the seasons. These modifications lead to a decline in species and a drop in productivity for the forest-wood sector. As everywhere in Moselle, the Thionville public forest, with its 700 ha of woods, is suffering. She has seen her population of conifers die off within a few years. “Firs and pines have been destroyed by bark beetles, which have multiplied the laying cycles”, laments the elected official.

Natural regeneration
Suddenly, the objective is to “review the planting system. With essences coming in particular from Canada ”. However, there is no guarantee that the transplant will take every time. And that the renewal of the wooded park be guaranteed. The other lever then consists in “causing natural regeneration.” We let nature do it, and the most resistant essences will come out on their own. “

Convention ONF
Through its agreement with the ONF until 2034, the City can count on experts in the field who watch over species such as milk on the fire. They are working to eradicate the concessionary caterpillars with natural techniques, therefore without chemicals.
During the upcoming mandate, “we will end the exploitation of conifers, decimated by insects, announces Jean-Christophe Hamelin, who reminds us that the Thionville forest, with unique faunistic interest, constitutes” a real carbon sink “.
