Shell Bank Bayou Cypress at Least 450 Years Old
N 30 09.910 W 090 27.033
Here is the data on the landmarked cypress featured in the December BLOG entry.
Diameter 49 inches
Radius 24.5 inch
Bore obtained: 3.25 inches
Rings counted: Approx. 90
Projected age Calculation:
3.25/24.5 (core sample/ radius)= 90 (rings counted)/x
X = 676 years
Based on a projected ring count of 676, a conservative estimate of the tree's age is 450 years. This estimate takes into account the likely faster growth at the tree's earliest phase of growth, which would show up in more widely spaced annual rings were a full radius boring (24.5 inches) obtained. As with many cypress trees this age, the hollow trunk precludes obtaining a longer length boring; therefore a conservative age estimate is appropriate
