Bear Trackers Use GPS in Bid to Preserve Animals


This articleĀ  on CNN describes how black bears in South Florida are being fitted with GPS collars to track their migration habits. The bears are facing an increasingly restricted environment which leads them to be isolated so that many of them are experiencing a loss of genetic diversity.

The researchers use doughnuts to entice the bears to traps. (They didn’t say which flavor.) The bears are then anaesthetized and fitted with tags and a collar. Hair samples are also taken for genetic testing.

The results of the work should show how much land needs to be conserved so that the bears have room to migrate and maintain healthy breeding populations.

The article doesn’t make clear that the GPS data has to be transmitted somehow from the collar so that it can be analyzed. In the captions of the photo galleries it says a text messaging system is used to relay the data. That’s an important link since a plain GPS receiver doesn’t transmit data.

Thorncrag Bird Sanctuary

Lewiston Maine’s Thorncrag Bird Sanctuary is located on the highest elevation of the city. The over 300 acre site contains many types of habitat, from wetlands to hemlock forests, for birds and other wildlife. Thorncrag has long been a popular site for outdoor recreation. Boy Scouts and other youth groups have found it to be a convenient opportunity to get to the outdoors without leaving town. More years ago than I like to think about, this is where I had my first experiences hiking and learning outdoor cooking and survival skills. The sanctuary is owned and managed by the Stanton Bird Club, a private organization. A new visitor center is currently under construction on the Montello St. side. It’s great to see that in spite of development in this part of Lewiston, a small piece of wilderness will survive.
