Opening

This garden also offers a gentle slope that runs from above water to below water. There is an opening at the bottom of the slope so that a frog or salamander can walk into it from the water.

Collaborating with nature

The American Crayfish is a pest in large parts of the Netherlands: they eat aquatic plants and toss in the soil and banks, which makes the water cloudy, prevents sunlight from entering and thus aquatic plants disappear. Waardenburg Ecology came up with the 'Craybar' (crab bar) to combat this lobster effectively and in an animal-friendly way. They are lured to a trap at the bottom of the water. Once inside, they can't get out because crayfish can only swim backwards. They then end up in a floating bin that can be closed or opened. When the tank is open, natural predators (such as herons and coots) can eat the lobsters. A smart, natural and low-maintenance solution.

The Craybar is designed in such a way that only lobsters are caught. The crayfish are lured by automatically feeding them a little bit, then they can no longer swim out of the trap, which is underwater at the bottom. Other animals can do that. Via a flexible tube, it runs into the Corten steel basin: a kind of snack bar for the heron, stork, grebe, coot, seagull and otter.
