쾨니히스무스‬에서 가장 멋진 ‪20‬개의 천연기념물

A true natural monument: This ancient oak tree has survived many storms and wars. With its imposing trunk and gnarled branches, it is a silent witness to history—and a perfect place to pause and marvel. The "wooden mother," as this natural monument is also known, has been determined to be 400 years old through tree-ring drilling.

The **black poplar** (scientific name: **Populus nigra**), also known as **Saar tree**, is a remarkable plant species in the poplar genus in the willow family (Salicaceae). Here are some interesting facts about the black poplar: ### Characteristics - **Height**: It can grow up to **35 meters** tall. - **Crown**: The crown is very tall, domed, and has spreading, strong branches. Mature trees can develop a multi-segmented crown. - **Bark**: The bark is dark, which gives the species its name. ### Distribution - The black poplar is widespread in **Eurasia** and **North Africa** and is a characteristic tree species of river floodplains. ### Ecological importance - This tree species was originally widespread but is now critically endangered. It plays an important role in its ecosystem, especially in riverine landscapes. ### Uses - Black poplar wood species are often used in the furniture industry and for other wood products. The black poplar is not only a beautiful tree, but also ecologically and economically important!

A true natural monument that has already caused a lot of problems.

A huge, gnarled poplar (probably) that makes more of an impression on me than the 1000-year-old oak tree in Gerolfing

Very distinctive tree on the Danube. The tree offers many insects a habitat and is also a way marker. The poplar has an imposing trunk - around 2 meters in diameter. It comes close to the path. Further upstream is an old silver poplar.

The tour leads right into an interesting section of the Donau-Auen (European protected area). You will pass an old fort surrounded by an oval moat and standing on an artificial island. There are waterfowl and beavers. Parts of the trail may be flooded after prolonged rainfall. In places, the path narrows to a narrow path, over which fallen trees lie and which is lined on the left and right by vegetation, some of which is tall. Long pants and tops with long sleeves and sturdy shoes are therefore recommended, also because of the many mosquitoes. The atmosphere is jungle-like. You should have very good local knowledge or a working navigation system (battery!), otherwise you can get quite lost.
