There are a number of proposals in the current book advocating elimination of spike-forks from legality, and making only 50" or 3 brow tine moose fair game.
This has support of the department and it is not unlikely that the end result will be 50"/3-tine for the whole Kenai.
Recent aerial moose counts (last week, excellent flying/spotting conditions) show a bull:cow ratio of 6:100, after excluding yearlings.
For years now spike-forks have made up around 60% of our harvest, so the proposed new regs would likely cut the moose harvest by about half.
Natural predation is not to blame for the skewing of the bull:cow ratio, it is clearly the result of current management. The KP was the first area to go to spike-fork/50", and now we are seeing the end result.
If a change in regs results in a better bull:cow ratio after a few years, we might see spikes made legal again, or perhaps a limited number of "any bull" permit hunts... But the way things are now we can expect big reductions in opportunity here for some time to come.
