This bull moose was videotaped in the southern Green Mountains on the second weekend of deer season. And it’s a lovely sight to see. Moose populations were booming in the early 2000s, but numbers have since dropped precipitously. The population estimate the state currently gives – around 2,200 statewide – is about half of what it was a decade ago. Biologists say that during the boom years, the population was high enough in parts of northern Vermont to exceed the land’s carrying capacity, and so part of the reason for the crash was depleted habitat. Another culprit was winter ticks, which are enabled by climate change. (Warmer winters means more ticks and a longer tick questing period.) Brain worm is another culprit; this parasite is carried by whitetailed deer and spread in deer feces, so as deer populations grow, moose populations suffer.
The state is currently conducting a radio-collared moose study which may shed some more light on moose and tick interplay. In the meantime, all healthy moose sightings – especially in the south, where populations were never that high – are great to see.
