In this Valley Immersion, we trek into a unique lowland-to-highland region shared by humans, apes, birds and forest kin to ask: what does it mean to belong to Earth and connect with more-than-human beings as custodians of land and life? Held by the forest and mountain ridges, we join citizen science efforts to gather data and explore the ecology of apes and birds to help us co-sense into mutual belonging and responsibility toward critical habitats and forest life. At the same time, we seek to understand the dynamic of an existence pulled by aspirations of greater livelihood and modernity of the communities living along the edge of manmade forest boundaries.
