Sessile oak in the Forêt de Bercé, Jupilles, France

Today we knows the really height of this oaks trees from Bercé.

In the past I have read a measure of 49,4 for the tallest but it's not so remote in terms of height.

It's true that 1 m is 1 m and for this records trees, I would them see in the future for compare to current data.

Currently studies have shown that trees grow in height much greater than before. This would be of greater concentration of CO2 into the

atmosphere.

In France are a lot of old regular dense grove, they was before maintened by the forest Service under the governance of Colbert for product very long trunk without branches for marine timber construction.

I know that the annual growth of the ring of Tronçais oaks is between 1,6 and 1,8 mm and this for all the phase of growth.The trunks are very regular and concentric to the diameter of the base to the first branches.
