July 6, 2025, Pollard Tree in Parc Naturel Régional des Boucles de la Seine Normande

A pollard tree is a tree that has been heavily and regularly pruned at trunk height (out of reach of animals). This repeated pruning creates increasingly large scars and bumps on the tree. The crown is constantly renewed and full of energy on an increasingly older trunk. After many years of pruning, the tree cavities become hollow.

Beautiful view of the Marais Vernier natural site. I had, when I was 18, the honor and the pleasure of working there in the company of several biologists. It is an exceptional site due to the richness of its fauna. On site live Camargue horses, Hyland cattle, Scottish sheep, gray herons and many other species. A few group visits are regularly organised. To participate, you must register in advance on the Marais Vernier nature reserve website.
