Anna's Tuin & Ruigte is a unique piece of polder nature in the Science Park Amsterdam where nature is given space. In the garden we use the principles of permaculture to shape this. In the rough - most of the area - we let nature take its course and at least intervene. Here we ensure a healthy soil and clear water. With this we offer a place for the wild plants and animals that come there spontaneously, grow, carrot, invade, crawl, clamber, swim and fly. With excursions, lessons, information boards and this website, we share our knowledge and experiences. Anna's Tuin & Ruigte is formed by a colorful collection of local residents, students, scientists, teachers, and other enthusiasts with a preference for working and learning in nature.
