It is the green heart of Leiden
Many different trees that attract various birds. With its green access roads, the park is part of the Green Network, which connects the outside area with the city center.
The ivy seems to go its own way, trees are not always cleaned up and the wood is laid in coarse shivers. This attracts many birds, insects, frogs and cleaners such as mushrooms. And bugs that were in the trees stay in the area like this.
