I personally don't hunt grouse but I'm appalled at the lack of response by the KDFWR and their in-ability to perform timely research or effectively combat the extinction of a game species from our state. This can happen to other species as well, so i see it relevant to all hunters. As for the grouse. Realistically, is it too late at this point? The habitat cause seems lame to me and as you say there is still prime habitat void of grouse. I suppose it is more fractured than it used to be and birds are essentially penned into certain areas. But as you say there has to be something else. Strategic logging could certainly change this but the populations are so low at this point I'm not sure you could tell if it was effective. I personally believe the raptor population has exploded and is having a huge impact. DDT kept hawk and owl numbers low (too low) in the heyday of small game hunting. I believe this to be the largest cause coupled with habitat issues. Disease seems unlikely (to me) and typically wont decimate a population. Fractured habitat and segregated populations should reduce the impact of disease as well. There are certainly examples of disease causing extinction (in this case extirpation) but its rare. The American chestnut comes to mind. On a side note Lucky dog (if you are who i think you are) i believe you took me and your boy Brett fishing on elkhorn creek over 20 years ago. I caught a monster smallmouth that sat in your freezer for some time, hell it might still be in there lol. If it was you thanks again for taking two young knuckleheads fishing. I applied what you guys taught me and waded stoner creek (and a few others) for several years after that. I never caught as many as you guys did but usually caught enough for a nice fried redeye supper and always enjoyed my time alone fishing creeks.
