Pedunculate oak

A pedunculate oak can reach an age of up to 700 years. The Heimans Oak at ARTIS is estimated to be around 275 years old (therefore dating back to about 1740) and the girth of its trunk is 3.5 metres. This tree existed long before ARTIS was founded, and is a natural heritage icon.

The status of this species on the IUCN Red List is least Concern.

  • least Concern

Eli Heimans

The Heimans Oak is named after Eli Heimans, a naturalist who contributed significantly to popularising nature studies. In 1903, he described the oak in the Groene Amsterdammer as follows: ‘There [...] rises again such a twisted, branching oak, a solid thirty metres; together with the great brown beeches, the pride of ARTIS’.

Fungal disease

Unfortunately, the Heimans Oak is suffering from a fungal disease that occurs naturally in older trees. This means that the tree will have to be felled if it becomes too dangerous. Experts check the trunk of the oak each year to monitor its health.
