Growing pressure on Sub-Saharan Africa's forest resources and their associated unwise use is attracting both scientific and policy concerns. Coffee forests are important natural resource settings exhibiting sustainability challenges related to governance, usage, and management. Collective management action measures, that center on the local community has been proposed to produce sustainable forests and forest communities through a more integrated, holistic approach to resource governance. This study was conducted to analyze participation in collective action of forest coffee management in Kafa Zone, Southwest Ethiopia where data were collected from 164 farmers using multistage sampling and analyzed by probit model. The coffee production experience, extension visits frequency, household education, off-income, market information, and boundary of users affect participation in collective action. Therefore, formulating accepted rules and regulations for forest coffee management, improving the frequency of farmers' extension visits, and increasing awareness of the negative consequences of forest coffee degradation among farmers enhance the chance of farmers' participation in collective action. Additionally, institutions related to defined boundaries of users had a positive outcome revealing establishments of boundaries that encourage local communities to have the right to enter, manage the resources, and have user exclusivity in forest coffee. The findings of the study show that market information influences participation in collective action. Increasing access to market information on the price and demand of forest coffee increase farmers' participation in collective action.
