Re: Percent Cylinder Occupation

I wasn't wanting to get caught up in maths at this point either. I was just thinking that if some trees would have more of their volume high up than others and that if it were calculated then the data might be useful. Photo mapping might be the easiest way to do it.

Re: Percent Cylinder Occupation

The centroid - exactly. So this could be thought of as the organisms ability to raise nutrients above the ground and create new cells. A high cylinder occupation is not necessarily the same as a high centroid position - for example a cone has the same cylinder occupation as in inverted cone but its ...

Re: Percent Cylinder Occupation

I've calculated the cylinder occupation of Long John Silver, a giant Eucalypt that my friend Ben Rose climbed and measured with Brett Mifsud. The tape wrap and height data is here on Brett's website: http://victoriasgianttrees.weebly.com The volume of 185.8m³ is excluding branches. Height is 81m, cb...

It's a shame but that's life - it's tough at the top.

Re: The Sgerm Spruce – the tallest native European tree?

Great photo! It's a very ragged exposed tree. Do you think the current leader could grow another 18 feet?

Re: The Sgerm Spruce – the tallest native European tree?

Hi Bart, Yes I was using my M-System. Video about it here: http://www.youtube.com/watch?v=pgEIJuZLjSg I didn't want to blast up the rope like in the video because I couldn't clearly see the branch supporting me from the ground so I took a steady walk up the rope! I'm still negotiating a license deal...

Re: Biogradska Gora – two new broadleaf tree height records

I'm out of ideas for the moment then. I still like 'Bell Bottom'.

Re: Biogradska Gora – two new broadleaf tree height records

As this is the champion Norway spruce in Biogradska and has a No.1 on it then why not name it after the first king of Norway: Harald Fairhair. The second king was called Eric Bloodaxe, but Harald II (great grandson of Harald I) was called Harald Greycoat. So trees '1' and '2' could be: Harald I and ...

Re: Percent Cylinder Occupation

Thanks Ed.

Well it's your discovery Kouta, and besides the Park will probably make up their own name for it if they ever find it for themselves.

I now have to find a name for the 59m tree I found high up on the bank...
