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 per year at least.

I also came across published Lidar data for a Douglas Fir permanent sample plot near Nelson, New Zealand. Those trees, planted in 1949, exceeded 60 m, with the tallest measured by Lidar at 66.8 m (albeit on sloping terrain). Almost 220 ft in 68 years.

Cheers,
