CONCORD, N.H. (AP) — Biologists say a project to tag 45 New Hampshire moose with tracking collars has been completed.

Fish and Game moose biologist Kristine Rines says 36 moose calves and 9 cows were tagged last month.

The tagging is part of a six-year moose mortality study that began in 2014. Biologists in New Hampshire and Maine are teaming up to help determine why moose populations in the region are declining.

The capture crew used net-guns and tranquilizer darts to capture the moose in northern New Hampshire so the animals could be collared. Blood and other samples were collected to help evaluate the health of the moose.

Earlier in January the same crew collared 107 moose in Maine and they are now headed to New York to collar moose there.
