NABA Butterfly Counts in Monterey County

There are currently four annual NABA (North American Butterfly Association) butterfly counts in Monterey County. Each count encompasses a circular area 15 miles in diameter, non-overlapping with other counts, and strategically placed for easy access and quality habitat. ​

 

These counts are scheduled for early to mid-June, generally the best season in central California for late spring and early summer flights of adult butterflies.  Counts are dependent on volunteers, and each count has a core of regulars, supplemented most years by semi-regulars and visitors.  ​The remote Big Creek and Hastings counts are most in need of volunteer counters.  The Monterey and Pinnacles counts are more accessible and thus have a larger core of regular volunteers. ​

 

Interested in volunteering for one or more of these counts? Contact us by phone or email, or refer back to this website in late winter-spring when the new season counts have been scheduled.
