Preserving Berlin's Oldest Tree: The Challenges Facing 'Dicke Marie'

Berlin's oldest tree, a majestic oak known as 'Dicke Marie', is facing significant challenges due to prolonged drought conditions affecting the region. Situated in Tegel, this ancient Quercus robur, estimated to be between 500 and 600 years old, is showing signs of damage in various parts of its crown, raising concerns among conservationists about its future.

According to forestry officials, efforts are being made to ensure the survival of this natural monument for as long as possible. Marc Franusch, head of the Tegel Forestry Office, expressed optimism regarding the tree's longevity and hopes for improved rainfall in the upcoming spring months. He emphasized the importance of careful management to prevent the tree from becoming overgrown by surrounding vegetation, which could further compromise its health.

'Dicke Marie' is not scheduled for any major pruning; instead, the focus is on stabilizing the environment around the tree to bolster its vitality. Franusch stated that the goal is to manage the tree's situation with great care and vigilance, thereby supporting its resilience against environmental stressors.

Once a popular destination for visitors, 'Dicke Marie' now stands somewhat isolated, away from footpaths near Schlosspark Tegel and the northern edge of Tegeler See, known locally as Große Malche. In recognition of its historical and ecological significance, the tree was designated as the first National Heritage Tree by the German Dendrological Society in 2021, an initiative aimed at raising awareness of particularly old and extraordinary trees.

The name 'Dicke Marie' is believed to have been inspired by the beloved cook of brothers Alexander and Wilhelm von Humboldt, who grew up nearby in Tegel Castle. This historical connection adds a layer of cultural significance to the tree, making its preservation even more vital.
