Shaded coffee has an important role in biodiversity protection and maintenance. This study aimed to analyze the cognition and willingness status of shaded coffee planting by convenience sampling of members of coffee production and marketing groups in Taiwan (not including Penghu, Kinmen, or Lienchiang County), and 159 valid responses were collected. We investigated respondents’ personal information, status of coffee production, coffee garden management, tree planting, market impact, and views of the coffee industry’s features in Taiwan. The study revealed that respondents’ farmlands were often small and scattered, and coffee gardens were usually minuscule in size. Among them, more than 82.1% of respondents had been exposed to shaded coffee knowledge through personal reading or experience (52.9%) and production and marketing courses (48.5%). Most of the respondents considered that the main benefits of planting trees were to improve biodiversity and habitats (57.6%) and reduce soil erosion (57.6%). In addition, up to 73.6% of respondents’ coffee gardens had other planted trees, which were mostly betel palm, fruit trees, and afforestation tree species. Overall, the main incentive for respondents to create shaded coffee gardens was that planting trees had economic benefits of fruit and wood harvesting. These results can be a reference for subsequent promotion of shaded coffee.
