The tallest man-made tree is in Walt Disney World's Animal Kingdom in the Safari and has many animals carved on the surface. The tallest natural made tree is found in Montgomery State Reserve near California. It is estimated to be over 1000 years old! It was also declared the tallest tree in 1996 and is 5 stories taller than the statue of liberty. It is a redwood tree and those can gather over half of a forests annual supply of water which is probably what makes them grow so big.
