I have the Okanogan Mule Deer and Black bear books and one or two others printed by the Dept of Game here somewhere. I think I picked them all up one at a time at Half Price Books over the years. I don't see them show up as frequently these days. One thing I can tell you is that your local library can get a copy for you to read from the University Libraries on interlibrary loan. They deal with managing the herd and one is on lion depredation. The others are follow ups to the one on Okanogan Mule Deer pictured above IIRC. Pretty dry reading.
