How amazing.
At least 1,000 years old.
So we just interviewed some elder foresters to ask where they saw big trees.
And we had clear to measure them.
But I found it's not efficient enough because there were so many trees.
It actually takes six years to survey whole islands.
In the middle of our project, we have some LiDAR experts join and they produce this 3D tree shape.
I remember it's over 50,000 images.
And after around five years, we figured out that the measurement of tree height is over 90%.
You find out... It's a cliff.
Yeah, yeah.
We cannot examine them by ourselves because researchers are few.
So we put them on a web and teach volunteers how to identify their height.
It's around 400 volunteers, and we plan to finish this project within a year, but surprisingly it's finished within one month.
Wow.
I think it's at least five years' work, yeah.
Yeah, yeah.
So I have a checklist of the promising target tall trees, and I have to make a hiking plan to reach those trees.
It's the third day we saw that tree.
The fourth day we climbed it.
