In addition to the traditional measurements, Eco-impact also makes use of (bio)monitoring as a method. For example, (crust)mosses, bees and plants can be very valuable for collecting information about the quality of the environment. For example, bees fly and harvest on average within a radius of 3 km around the hive, which is equivalent to an area of 27 km². In this way they are perfect (micro)samplers of the environment. Such (bio)monitoring ensures more understandable and more accessible measurement campaigns for the general public and is also less expensive than traditional measurements.
