Improper land uses may cause increased watershed degradation. Therefore, proper land use planning and development is essential for sustainable management of these mountainous watersheds. Two tributary watersheds of Keelong River in northern Taiwan were selected as the study area to evaluate and develop management options and conservation strategies for achieving sustainable development goals. Keelong River watershed with mean annual rainfall exceeding 4000 mm one of the wettest watersheds in Taiwan. Field investigations were conducted and the SWOT method were used to systematically evaluate physical and social economic factors governing watershed development and management options. Opinions of watershed residents were collected and analysed to help develop feasible and sustainable watershed conservation strategies and measures. The SWOT method was applied to evaluate the feasibility and suitability of watershed sustainable development goals and measures from environmental conservation, society and management viewpoints. This study partitioned the watershed into three portions (1) people-friendly creek-side conservation area, (2) mixed recreational and forest park area and (3) conservation protection area. These partitions will help achieve the sustainable development goals for the two study watershed. A sustainable development plan for these two watersheds may include proper mix of agricultural productions, living standard maintenance / enhancement, and ecological protection.
