Voyageurs officials said in a statement Tuesday that the park's moose population is estimated at 46, based on data from an aerial survey this winter.
Wildlife biologists say the moose population is holding relatively steady in Voyageurs National Park in north-central Minnesota.
They say that stands in contrast to the rapidly declining moose population in the state's main moose range in northeastern Minnesota.
Voyageurs officials said in a statement Tuesday that the park's moose population is estimated at 46, based on data from an aerial survey this winter. That's similar to estimates from surveys conducted from 2009-2011.
The survey report says it's not clear why Voyageurs' moose population appears to be relatively stable while the moose population in northeastern Minnesota has declined 65 percent from 2009-2011.
But the biologists warn that climate change and disease outbreaks continue to threaten the long-term viability of the park's small, isolated moose population, and that further monitoring is warranted.
