According to Van Sevenhoven the bosmarken were separate from the Beekberger mark, 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. There was a split between Lierder, and Speldermark in 1848. In the verpondingskohier of 1650 the Beekbergerwoud was deemed almost and the Spelderholt completely worthless.
