According to Van Sevenhoven there is a lot unclear about this mark, he concludes that it is one mark for the 4 buurschappen but it is generally referred to as Beekberger mark and Lierder and Spelder mark. The bosmarken were separate though the management was intertwined and the geërfden had some rights in the bosmarken. Sloet does not keep the bosmark  separate from the mark, which gives some difficulties. The markerichter was called erfholtrichter, there are 8 erfgenoten/gecommitterden, 8 vorsters and 1 markeschrijver/ontvanger.
