The rings are labeled #1-4, with the ring just below the bark representing the growth from 2012. Drawing a diagram or chart may help you to visualize the position of these rings. #1 = 2.7 mm #2 = 1.03 mm #3 = 3.8 mm #4 = 1.88 mm In which year other than 2011 did the conditions not seem conducive to a rapid growth rate?
