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

 
Circumference: 12'10''


Vertical lines in section of 3.25 inch core (enlarged) show variation in spacing of annual growth rings. Closely spaced rings indicate slow yearly growth

How Old Is This Shell Bank Bayou Cypress?


This cypress on Shell Bank Bayou (St. John the Baptist Parish) is a Louisiana Purchase Cypress Legacy Tree - “Alive in 1803” - based on comparison to other trees we’ve cored throughout Louisiana.

Can you estimate its age and circumference based on the age and circumference of other Cypress Legacy trees we’ve landmarked? (See our registry here of oldest known cypress in each parish for comparison to the Shell Bank Bayou tree).
Also check out previous Blog entries.

Please enter your “best guess” estimate in the comment  box below We’ll be posting the estimated age based on a circumference measurement and coring sample shortly--early January 2015.  Check back!

500+ Year Old Cypress Landmarked on Bayou Dorcheat, Webster Parish, Louisiana



Bayou Dorcheat 500+ year cypress landmarked


Bayou Dorcheat is one of the most scenic of  Louisiana’s  designated Scenic Streams, extending from Lake Bisteneau through Webster parish into  Arkansas.  Hundreds of old growth cypress line its banks,  enriching the  timeless sense of wilderness experienced while paddling along this remote stream. The Louisiana Purchase Cypress Legacy landmarked one of these cypress—LPCL Plaque # 38.Here’s what we found out about this representative example of the old growth cypress along Bayou Dorcheat:

GPS coordinates 32 54.837 North  093 23.211 West (on left bank of bayou paddling south)
Circumference (above buttress) 13 feet 4 inch circumference
Diameter: 50 inches  Radius: 25 inches
Core sample: 4.5 inches
Rings counted: Approximately 130
Projected age; 500+ years

Projected age of 500+ years takes into account likely faster growing period during early growth period. Like most of these ancient trees the inside is hollow, meaning that core samples reflect slower growing later years.

To view this tree, launch boat at the Hwy 2 access. Paddle south about twenty minutes. Tree is located on left side (east bank) about two minutes paddle before teaching the overhead power lines.. The plaque is not easily visible as you paddle south towards the power lines; however, it will be visible viewed on the right bank heading north about two minutes from the overhead power lines. It is quite a distinctive tree with a full canopy and swirling bark.
We'll be adding this tree to our State wide registry of oldest known trees in each Parish.
If you know of possibly a large/older cypress in Webster Parish please let us know!

Louisiana Bicentennial Cypress Legacy Treasure Hunt

A Registry of the Oldest/Largest Known Cypress Trees
 in Each Louisiana Parish

The Louisiana Bicentennial Cypress Legacy announces a statewide treasure hunt for the oldest and largest (in circumference) bald cypress in each parish.  Follow this link to our registry to see the trees that have been landmarked.  Many parishes have not yet had their oldest/largest trees identified and registered.

If you know of a cypress tree in your parish that may be at least as old/large as that shown, or if you can help us fill in the blank entries for parishes that are lacking identified trees, send info to Harvey Stern, coordinator, Louisiana Bicentennial/Louisiana Purchase Cypress Legacy at lapurchasecypresslegacy@gmail.com.
