MOOSE POPULATION GETS A CHECKUP
Counting moose is a challenge. A recent survey in this area showed a drop from 5,000 to 4,000 animals in one year. But researchers admit there could be a 25% margin of error in those figures. That's because it's hard to find the moose in heavily wooded areas. The collaring project will make counts more accurate.
