The institutions-cum-forest use dynamics literature is growing, albeit marred by scanty evidence on actor roles in shaping the process in sub-Saharan Africa. Cameroon represents a useful “laboratory” to explore such actor-driven change processes. Recent studies have reported the change process linked to a colonial hangover in parts of Cameroon that came under French influence, suggesting the need for fresh evidence to uncover such change processes in parts of the country which came under British influence. Using the Bakossi Landscape as a case, this article (i) traces the pathways of forest-linked institutional change, (ii) estimates the role of actor groups in shaping forest-linked institutional change, and (iii) explores the determinants of forest-linked institutional change in the Bakossi Landscape. A representative sample of 116 households in 3 selected communities was performed. This was complemented by focus group discussions (n = 6) and key informant interviews (n = 10). Descriptive statistics were used to establish forest-linked institutional change, while the ordinary least square was employed to estimate the effect of actor groups and other determinants on forest-linked institutional change. The results lead us to the following conclusions: First, both forest-linked institutional structures and processes witnessed changes over the years. Second, raising the intensity of actor group processes (in-migrants, local elites, traditional leadership, timber dealership and NTFP traders) significantly decreases changes in forest-linked traditional rules, while migration, state officials and the church significantly increase changes in forest-linked institutional structure. Finally, an increase in the composite index of process-mix traditional leadership and NTFP traders decreases changes in forest-linked institutional structures. Future studies should uncover gender dimensions of changes in forest-based institutions, as well as the role of conflict actors in engendering institutional change.
