Video: Minnesota Mystery: What’s Killing the Moose?
"The number one driving factor is likely climate change. We've lost half of our February snow depth in a 20 year period; we've seen a 5 to 6°F increase in August maximum temperature in about a 60 year period." ~ Seth Moore, Wildlife Biologist Grand Portage Band of Chippewa (02:54)
"We know that moose don't do well in warm temperatures. We know that if it's not cold enough they don't do well either. So is that thermal stress causing them to be predisposed to underlying health conditions that they wouldn't have normally?" ~ Lou Cornicelli, Wildlife Health, Minnesota Department of Natural Resources (03:10)
"It isn't one thing that's killed the moose so far in the study; it's been predator related causes and it's been health related causes, kind of a 50/50 split. And the health realted causes have been also kind of a number of things, parasites and other even unknowns. Where we had really good diagnostic samples, but there wasn't an one thing that pointed to why that moose died." ~ Michelle Carstensen, Wildlife health, Minnesota Department of Natural Resources (05:40)
"The problem is not limited to Minnesota. Researchers elsewhere along moose's southern range, from Montana to New Hampshire, are seeing similar declines." ~ Narrator (06:34)
"There's really not a whole lot you can do. We're not to the point, at least in our study, where we can really point to climate change as a clear cause, but that's in the back of our mind. If we can really pinpoint the overlying cause, then, can we even do anything about it to really curtail this decline or are we just really documenting a species on its way out of our state." ~ Michelle Carstensen, Wildlife health, Minnesota Department of Natural Resources (06:47)
