Snow Brook elevation/vegetation change

These datasets assess the before-and-after condtion of biomass and forest cover and elevatio for the years 2021 and 2022, within the context of a fish passage restoration project. The project entailed the replacement of a failing, undersized culvert with a large box bridge in the Snow Brook area of Sedgwick, Maine. Lidar data collected via drone flights were instrumental in this study. The analysis aims to assess aggregate parameters and t percentage changes observed during 2 drone flights before/afterproject construction and assess shifts in ecological function at the site following the restoration project.
