We visited Dame Judi's garden last summer and scanned a 200 year old oak tucked away in a wild corner. We then estimated the mass of the tree, and its leaf area/count - 25 tons and 260k if you're interested! We then generated a nice fly-through of the garden and around the tree, which then talked through with Dame Judi - she was suitably impressed by the detail. Interestingly, our estimate suggest the tree has 12 km of branches, more than any other tree we've come across, even in the tropics.
