Just caught this. Ron Ron is more than 2 dollars a board foot, more like 4 dollars and up. It is very scarce, very hard to find.
I would be very surprised if there was a 30 cm tree of it. Excellent growth of Ron Ron is like 1 cm a year.
This photo is of ron ron with very good growth that are 3.4 years old. ( I was told that this represents 10 years growth at another plantation (not TATF))
The article by the way you reference was written by Lucia, who helped write the book "The Timber Trees of Costa Rica" who worked for us during our research phase.
Let's imagine that you have a circumference of 40 inches (I am being generous), a simple way to calculate it would be.
40/4 = 10 10 squared = 100 So for 4 varas (33 inches), you would have 100 pulgadas (132 square inches)
If the log is 55 feet, 500 pulgadas, or 455 BF. 20,000 / 455 = 44 dollars a BF!
Yeah, no way at all, the log would be 2,000, not 20,000. And that is only if it is a perfect log, no defects. There are 20,000 dollar logs, but they are VERY rare.
The moral of the story, don't believe farm workers or even farm managers. I have seen farmers just about give away trees before, and I have seen farmers who thought that their tree was worth the price of a new car.
