For those who may not know, SFW is funding a study in UT to see if mule deer can be transplanted from areas of over-population to areas where the herd is under objective. Scientific history suggests that mule deer do not transplant well, but SFW didn't believe the history and wanted to try it again. In January they translocated and collared 102 deer, and also collared 50 resident deer as a control group. History seems to be repeating itself, as to date there has been mortality of 5 of 50 resident deer and 44 of 102 translocated deer. You can read more about the study and the results here.
Now The Don is admitting that the biologists may be right, but he is suggesting that transplanting may still be successful in one way, by feeding the predators transplanted deer and taking pressure off the resident deer. He is also suggesting they change the parameters of the study midstream, as I suspect he is not liking the results. Here is an email from Don. Any opinions?

Thanks for your analysis, and the additional thoughts and the conservative or cautious estimate and cause of unknown deaths.
In late August, you reported on dead deer found and unharmed, the rest have been scavenged
5. thoughts
1. Do deer just fall over and die in good habitat in the summer, when other deer are showing no signs of disease?
2. If you assume a random distribution of deer dying from say the Monday they were checked, till they were found dead the next Monday, a fair number of deer would have died in the Friday, Saturday, or Sunday and the fact all but one dead deer has been scavenged, coyote death is probably a good probability of death. I doubt most of the deer died on Tuesday or Wednesday of natural causes giving coyotes 3 to 5 days to find them and scavenge them.
3. I think one enhancement of the study next year is to not look for fawns until September. Jim Karpowitz said several times from his deer study it is futile looking for fawns until late August, or September. And the. Focus could be greater intensity on finding the cause of death in 7 days interim from survey.
4. Sacrificial anode theory. I think this study is proving the sportsmen right, and the DWR right. The DWR - specifically former game manager mike welch - that the transplanted deer didn't do as well as natives. However, sportsmen might be right, the transplanted Deer take some pressure from predation of native herds. Thus, in the end, a successful restoration of the Henry Mountain deer herd. A combination of better habitat, water,predator control, and transplants. in engineering, sometimes you attach a piece of zinc to a copper pipe. The system has unsolvable corrosion problems, so you put something for the corrosion to eat and let your pipes alone.
5. For these coyotes to be scavenging every caucus shows there are still way to many coyotes, and there ought to be a super intensive coyote control program the next five months. This study isn't to see if coyotes or predators kill deer. The objective as I understand it is to see if Deer can be transplanted, and increase deer populations
Sorry, the old scientist comes out in me once in a while, and these are some facts to consider.
Thanks for the persistent hard work. Very valuable information, we are not doing a study. We are getting data to design, engineer, build and sustain abundant deer herds!
