No single person has even the faintest idea why such a sheer plunge is being seen in the populations of moose in North America. But, the populations are increasingly declining in different regions, including New Hampshire, Montana, Minnesota and British Columbia.

It has been discovered that Minnesota used to have two moose populations almost two decades back, which were geographically segregated. One of the two populations has declined to almost negligible, i. e. from 4,000 to just 100.

On the other hand, the second population found in northeastern Minnesota has been on continuous fall. The number of moose has dropped to 3,000, from 8,000 earlier. The report said that a plunge of almost a quarter is seen each year in the species.

Montana had 769 moose in the year 1995, whilst the count downed to 362 the previous year.

"Something's changed. There's fewer moose out there, and hunters are working harder to find them", said biologist Nicolas DeCesare from the Montana Department of Fish, Wildlife and Parks. His work is to count moose in the state. The aim is to look for the reason of the fall in the moose population and the extent of the same, according to Nicholas.
