Planting of young trees around the Alte DonauLIFE+ Alte Donau

In order to ensure the long-term preservation of the typical lakeside tree population, a total of 245 young trees were newly planted under the auspices of the LIFE+ project.

Black poplars, white poplars and willows characterise the typical landscape around the Alte Donau. Close to 1,200 trees line the grassy areas around the lakeshore. Many of these huge and impressive old trees have now reached their natural age limit.

In order to ensure the long-term preservation of the typical lakeside tree population, a total of 245 young trees were newly planted under the LIFE+ project.

In addition, selected naturally occurring saplings which would ordinarily have been removed in the course of landscape maintenance work were left in place, while non-native species (so-called neophytes) such as ailanthus and robinia were cleared away.

Among other sites, young trees were planted beside the path along the lower section of the Alte Donau, on the grassy area at Dragonerhäufel, in the dog zone next to the Angelibad lido, around the Kaiserwasser arm and at the newly regenerated ArbeiterInnenstrand and Strombucht sunbathing lawns.

Measures to prevent beaver damage

The young trees were fenced off to protect them from beavers and the trunks were painted white to prevent the bark splitting open during the growing-in phase as a result of solar radiation after night frosts. Sand was also added to the white paint to make the bark unattractive to beavers.
