Re: Europe vs. the eastern US - comparing tree heights

Kouta, I misunderstood your comment about P. strobus. It was measured with the cross triangulation tangent method. Bob and Will took tangent methods from three different locations.

Re: NY Rucker Height Index

Bob,
I’m on board. If a couple of key measurers are also on board, it could be a go. It would be fairly simple to compile a document from our postings.

It is in the Foret Dominiale de Ribeauville, France. 46.3' 14.11m downy hawthorn Crataegus mollis Belle Isle, MI USA Doug Bidlack Pecan at the Jardines del ...
