As a Postdoctoral Fellow, Steven Yu's research focused on the historical land use/land cover change in the Mistawasis Nêhiyawak First Nation and Muskeg Lake Cree First Nation. Back in the 1960s to 1980s, a large amount of band lands was surrendered to non-indigenous owners. From the 1990s to now, the bands are recapturing fields, and registering them as reserved lands. However, the recaptured lands are not identical to the surrendered lands.

Steven's research is to investigate the historical land use and land cover change of these band lands, including surrendered and new-purchased fields as well as the surrounding regions through remote sensing imagery. Steven's study of land stewardship and land ownership for these two First Nations, coupled with his mapping expertise makes his role very important in the Bridge project. The main goal of the BLWS project is improving the surrounding environment while committing to the protection of Indigenous values, treaties, communities, lands, and resources.
