During my study biology, I spent a lot of time on the Dutch island Schiermonnikoog. The eastern half of the island consisted of a salt marsh and was the place where I did part of my fieldwork. We looked at the gulleys and the different vegetation types. It would have been a lot easier if I had had a drone at that time. Now I have one, this was one of the first places that came to mind to have a look. The gulleys made nice lines crossing through the fields. Ponds of salt water gave another pattern again. A really nice and different way to look at the landscape.
