I put my base where there are at least one of the big snags on the ground. Each of the roots, the center all can have a beehive attached, and sometimes on ground between and because they are on different levels they will be happy. Most I have gotten on one was 8. Otherwise there is always one side of base that is higher so I dig down, make a flat spot, an area protected from most stuff. One time I kept having a problem and finally found a skele at night was using a visible one for target practice. There was a fence but he was went to a fairly high area where just the roof showed.

When you get a pick you might consider a moat. Very effective.
