White-tailed Deer Tooth Collection and Antler Measurement Study Underway in Idaho Units 2 and 10A
Idaho Fish and Game has initiated the third consecutive year of its white-tailed deer age study in units 2, 10A, and select controlled hunts in northern Idaho’s Panhandle and Clearwater regions.
Hunters pursuing white-tailed deer in these areas are invited to voluntarily contribute to this ongoing research by submitting a tooth from the front lower jaw of their harvested animal.
Scientific Importance of Data Collection
Samples collected from hunters provide crucial information on the age structure of local white-tailed deer populations. Accurate age data is fundamental for managing sustainable deer populations, as it influences decisions on harvest regulations and habitat management.
Collecting over 1,000 teeth in the 2023-24 season, the program has generated valuable insights, with 2023 findings already published and new results anticipated in early 2026.
Additional Antler Measurements Sought
Hunters who harvest a buck are also asked to submit detailed data on antler characteristics, including the number of points on each beam and main beam length measurements.
This information assists wildlife biologists in evaluating whether antler size metrics can reliably predict deer age, a factor with implications for population assessments and hunting regulations.
Context From Wildlife Science
White-tailed deer (Odocoileus virginianus) exhibit age-related changes in dentition and antler development, making tooth wear and replacement patterns dependable indicators of age structure.
Antler size, influenced by age, nutrition, and genetics, often correlates with reproductive success, affecting herd dynamics and management goals.
Participation Details
- Tooth collection envelopes are available at all Idaho Fish and Game regional offices.
- Participation is voluntary but highly encouraged to improve data accuracy.
- Data from the 2024 collection will be incorporated into management decisions in coming years.
The Idaho Department of Fish and Game continues to rely on hunter collaboration to enhance the scientific basis of white-tailed deer management in the region.
