Ohio State University has a unique application of valuation. It's common for universities to label various plants and trees to facilitate identification and knowledge. For example, UNCW has small placards at the base of many trees on campus with the common name and scientific name of the species. Ohio State takes it up a notch and adds a conservation message. I'll let these pictures do the talking:
Eastern White Pine
How do they do the valuation?
Can anyone think of other applications where this type of valuation might be useful?
