Curiosities
Elm wood is very resilient when kept constantly in water and due to this property it is used to build boats, bridges, dams, outdoor stages and general carpentry. It is because of this resilience that Colbert the famous French statesman, when working for Louis XI, had the idea of planting elms alongside all the roads in France so they would always be ready to build a naval fleet (unfortunately elm wood is not used anymore to build boats). Nowadays, the elm population has decreased due to Dutch elm disease. Fortunately the species Ulmus parvifolia is not affected by this disease.
