This is somewhat of an illusion, as you zoom in and out of the pseudo-absence map you will notice that the dots do not change size. That is, when you are zoomed out on the map it will appear like the pseudo absence points cover much more space than they really do. As you zoom in on the map you will find there is not as many as originally perceived. Rest assured, the BCCVL generates only as many pseudo-absences as you tell it to.
