From another Fairbanks commenter, Fran Mauer who can't currently comment - ADN is working on the glitch - Part 1 of 2:

Mr. Spraker is wrong on the facts of the Unimak predator control issue.  This project was concocted by ADF&G and the BOG in an attempt to establish a precedent for State sponsored predator control on National Wildlife Refuges.  A number of “trumped’ up claims by the State painted a false picture for the situation on Unimak.  It was the over-harvest of male caribou by commercially guided trophy hunters that created an unnatural bull:cow ratio, all under the auspices of “sound scientific management” by the State that figured in the decline of Unimak caribou.  Nearly 100 year pioneer caribou biologist Olaus Murie found that caribou populations on this restricted island have widely oscillated from zero to several thousand. These are natural dynamic conditions to be expected for caribou on Unimak.
