It hosts 50 kinds of butterflies and moths, offers its seeds for game birds, squirrels and rabbits and provides its trunk for woodpeckers and bats as nests.
Meanwhile, beetle Odontota dorsalis mines its leaves, beetle Megacyllene robiniae and Euwallacea fornicatus bore its trunk, and fungus Fulvifomes robinia rots its heart, keeping it in natural balance.

For its striking white flowers and elegant leaves, Robinia was brought to Europe in the early 17th century. It was distributed all over European botanical gardens as a rare ornamental exotic for 200 years from 1601 France, to 1662 Italy, to 1672 Germany, later Austria, 1800 Switzerland.
At the end of the 18th century, Central Europe had a “Robinia Mania”. Increasing demands of wood for industrialisation, need to control erosion after forest degradation, need to stabilise new railways and rivers embankments.

Industrialisation allied people with Robinia for its long-lasting quality, rapid and easy growth, big roots net and a lack of predators and pests.

The first plantings of Robinia in South Tyrol date back to the first half of the 19th century, also as an ornamental tree. By the middle of the century, the species had already begun to grow wild.

In front of you, this very old Robinia tree is protected as a natural monument. It might be planted here as a street-side tree, having been part of the old city centre’s landscape for more than at least 50 years.
