What Should You Know About Bear Hair Samples?

Question

Accepted Answer

Collecting Bear Hair Samples When collecting bear hair samples, it is essential to consider the bear’s behavior and habitat. Bears shed their hair throughout the year, but the best time for collection is during the spring and fall when new hair growth is most active. Use a soft-bristled brush or a gentle comb to collect hair samples from tree trunks, branches, and other surfaces where bears may rub against. Avoid collecting hair from areas with high human disturbance, as this can contaminate the sample. Collect at least 10-15 hair samples, and store them in a dry, airtight container to prevent degradation.
Analyzing Bear Hair Samples Analyzing bear hair samples involves identifying the species, sex, and age of the bear. To do this, compare the hair sample to a reference collection of bear hair specimens. Use a microscope to examine the hair structure, including the cuticle pattern, medulla, and cortex. Measure the hair length, diameter, and pigment distribution to identify the species and sex of the bear. Hair analysis can also be used to identify the presence of bear scat, which can be used to track bear movement and behavior.
Storing Bear Hair Samples Proper storage of bear hair samples is critical for accurate identification and analysis. Store hair samples in a dry, airtight container, such as a plastic bag or a glass vial, to prevent degradation and contamination. Label the container with the collection date, location, and any relevant notes. Store the container in a cool, dark place, such as a freezer or a secure storage facility. Keep the storage location consistent, and avoid exposure to extreme temperatures, humidity, or light.
