Quick Answer
To determine the age of a moose in the wild, look for worn teeth and the growth patterns of their antlers, which typically reach their maximum size around the age of 12-15 years. Count the number of years since the antlers' growth pattern last changed, which indicates a new set of antlers has grown.
Assessing Moose Antlers
When assessing the age of a moose, one of the most accurate methods is evaluating their antlers. Moose antlers grow and change yearly, with clear signs of wear and tear from the previous year’s growth. Antlers typically reach their maximum size around 12-15 years old, but they can continue to grow in size and complexity until around the age of 20-25 years.
Measuring Antler Growth Patterns
The annual growth pattern of a moose’s antlers is determined by the number of years since the antlers last changed. This can be visually determined by looking for scars, cracks, or areas of worn-down velvet on the antlers. By counting the years since the last change, you can accurately determine the moose’s age.
Considering Dental Wear
Another key factor in determining a moose’s age is assessing the wear on their teeth. Moose have 32 teeth, but the lower incisors wear down at a consistent rate, with a loss of around 5-7 mm per year. By counting the years of wear on these teeth, you can estimate the moose’s age. For example, a moose with 20 mm of wear on its lower incisors would be around 3-4 years old, while one with 80 mm of wear would be around 10-12 years old.
