The population of Elm is heavily decreased with the spread of Dutch Elm disease. This disease spreads by beetles that are carriers and in most cases is fatal. The disease infected the Elms worldwide. Due to this reason the wide industrial use of Elm dropped. Fortunately now its population is starting to grow again. Elm trees often grow long and straight trunks. This gives nice long boards with stable quality.
Heartwood is light to medium brown and the sapwood is mostly well defined and paler then the hardwood. The grain pattern is very often interlocked what gives elm his strenght. Elm is pretty resistant to decline by water what makes it a wood that is also ideal for outdoor furniture.
