Wildlife biologists say the moose population is stable in Voyageurs National Park in north-central Minnesota, in contrast to a fast-declining population in the state's main moose range in northeastern Minnesota, the Duluth News Tribune reports.
Voyageurs officials on Tuesday said the park's moose population is estimated at 46, based on data in a new report from an aerial survey this winter. That's similar to estimates from surveys conducted from 2009-2011.
Officials warn that despite moose-population stability in the park, careful monitoring is still necessary due to threats including climate change and disease outbreaks, the News Tribune reported.
Scientists are studying more about why the moose population in northeastern Minnesota has declined as much as 65 percent from 2009-2011.
