At the beginning of the year, Korea Forest Service announced Street Tree Planning and Management. The plan explains the expansion of the role of street trees and the increase in citizen’s interest in street trees. The plan also mentioned the setting out assessment indexes of street trees is included on their to-do list. The problem is that the indexes didn’t include any assessment indexes related to the value of street trees. Street trees also provide their own functions which are good for citizens. There is a software that estimates street trees’ values and using the software, we can improve citizens’ recognition of street trees. So in this study, we investigated street trees on campus. We tried to find out the composition and population of street trees and estimate their value especially in terms of carbon storage and sequestration. To estimate carbon storage and sequestration, we needed to measure morphological parameters of street trees including tree species, diameter at breast height, total tree height, crown dieback and crown light exposure. We measured those factors in street trees on Kangwondaehak-gil which runs through Kangwon National University. With the measured factors, the value of street trees in terms of carbon storage and sequestration is obtained. Plus, we tried to figure out the difference between when we measured those parameters ourselves and when we measured them with LiDAR sensor. We made assumptions that when the morphological parameters of street trees vary, the values should also vary. So we verified how big of a difference there is and whether the difference affects the value of the trees when we used LiDAR seonsor. There was a difference between the field measurements and those obtained using LiDAR sensor, but not so much as to change the value of the trees. Therefore, through this study, it could be expected that LiDAR sensor can be used when measuring and evaluating street trees in the future.
