The LIFE project will scientifically monitor 360 nesting boxes. If nesting boxes are installed according to the trial guidelines for the LIFE project at other locations and these can also be monitored, we will integrate this data into our project dataset. In the province of Antwerp, this monitoring will take place with the help of work-placement students. Other nesting boxes will not be included in our analyses but we are, of course, interested in experiences and findings and will certainly support this type of activity.
