Summary

Story summary

Chronic Wasting Disease threatens North American deer populations, with notable risk in Alberta and British Columbia.
Research led by Dr. Alfred Roca shows white-tailed deer genetic variants can reduce CWD impact by up to 90%.
In Illinois, 43% of deer carry these protective variants, while isolated populations like the Colombian white-tailed deer lack them.
Current management emphasizes reducing deer densities, but integrating genetic insights with traditional methods could improve conservation.
