説明 | How were these numbers obtained? The FWC uses the most cutting-edge methods for surveying bear populations and is one of this nation’s leaders in applying sound scientific methodology to estimate bear populations. The FWC surveyed nearly 11 million acres in Florida. Barbed wire enclosures containing a small food reward were used to collect hair samples left behind when the bear squeezed between the wires for the food. State-of-the art genetic analysis of these hair samples allows us to identify individual bears. Researchers are able to determine if the hair sample is from a bear that has already visited an enclosure or a new bear not previously identified. Population modeling work based on these genetic results, which is conducted by the University of Tennessee, provides us with an accurate estimate of bear numbers.FWC trail cam photo |
