Professional and amateur tree hunters are combing our state looking for an elusive trophy, a big tree. You can do it too! The Minnesota Big Tree Registry has four national champions and 53 state champions. There are two species without a champion—northern mountain ash and mountain maple. Not all champion trees are giants. They're just the biggest reported living tree of a species. In the case of the diminutive chinkapin oak, the current champion has only 31 points and is the smallest “big tree” on our registry. Become a big-tree hunter! You just need a measuring tape and ruler to get started. Watch our video on how to measure a big tree. These biggest trees are found in forests, parks, or front yards.
