Lidar Tree Height paper and methodology

Hi All, Came across this paper on doing a large scale analysis of regional Lidar data in order to correctly measure large tree heights: https://www.mdpi.com/1999-4907/9/11/702/htm It looks as though they have put a bit of thought and effort into the down slope error issue with Lidar, even more of a ...

Re: Lindsey Creek Giant

Why is the rod considered a red herring ? What is diversionary about the rod ? Hi Michael, The rod/pole/tool was not apparent as such in the low resolution photo originally posted by Mario. At low resolutions, the shadow from the rod/pole/tool could be interpreted as strong indicator of included ba...

Re: Lindsey Creek Giant

HI Michael and Mario, Michael's last photo makes it blatantly obvious that the photos are of the same tree. The location of the inclusion on the upper surface and features in the bark are a real fingerprint. The obvious pole on the lower cut surface is just a red herring. The felling must have been ...

Re: Lindsey Creek Giant

Hi Mario

Google's image search turned up some higher resolution images of the same photo. To my eyes the dark line on the lower cut does seem to be a shadow of a pole lying on the cut. Please see attached for one example.

Cheers,
Matt

Re: Lindsey Creek Giant

Michael, I see the cut now. Great to hear your elucidating reasoning. //Fredrik That's two trunks, not one. It's very similar to this one here, where the INCLUDED BARK is revealed that used to be hidden. Hi Mario, Is the include bark the linear indication on the lower surface of the scarfing cut? I...

Re: Second Growth Redwood 275 Feet Tall

An update on the Whakarewarewa redwoods - Recently released Lidar data revealed the location of the tallest tree in the grove in 2010. Laser rangefinder (Nikon Forestry 550) measurements last week showed that tree to be 73.4 m (241 ft) tall at 116 years of age, and probably still growing around 1 ft...

Re: Second Growth Redwood 275 Feet Tall

Hi Mark and Don, The redwoods (Sequioa) at Whakarewarewa, Rotorua are pushing 72 m (236 ft) at around 110 years since planting [1]. Chris Earle considers these to be the tallest known horticultural (i.e. deliberately planted) conifers in the world [2]. The second tallest (known) planted conifer is a...

Re: Chile Trip Part 2: Parque National Vicente Perez Rosales

Unfortunately, some of Andrea's tape drops are suspect as well. He did an unauthorised climb of a large kauri at the Cascade Kauri Regional Park - one at the northern end of the Auckland City loop track - and spend the night in it (http://superalberi-messaggeroveneto.blogautore.repubblica.it/2015/08...

Re: The Tallest Trees in Africa

Hi Kotua, DBTree is probably Drew Bristow, a NZ aborist and tree climber. He is part of a group who have documented expiditions in Africa - see http://www.explore-trees.com/#intro There are a few reports on the tree, e.g. http://www.cnn.com/2013/11/07/world/africa/aint-no-tree-high-enough/ The tree(...

Re: A notable tree holiday - Waipoua - Yakas Tree

The Yakas Kauri is the 3rd large tree with easy access in Waipoua. It is named after Nick Yakas, who re-discovered the tree in 1966, after first seeing the tree 40 years earlier when he was scouring the forest for kauri gum. Officially, it is ranked 7th by merchantable volume. By AFP points it is al...
