Yes, it is biological sampling! We have some biologists and ecologist in the team that took care of the methodology. And indeed we have taken a simple approach with some string/ropes that works pretty well as you said. But we have a lot of sites in different parts of the world to sample on a yearly basis. I was looking for a way to make this easier for the people in the field. Thanks for your tips!
