This research aimed to: 1) develop a plant information system, 2) create an augmented reality (AR) application to display plant data, and 3) evaluate user satisfaction with the plant information system. The sample groups consisted of: two representatives from Doi Suthep-Pui National Park, selected through purposive sampling, who provided and verified plant data; two representatives from the national park and three academic experts from higher education institutions, also selected purposively, who evaluated the system’s effectiveness; and 30 participants, including students from Chiang Mai Rajabhat University and national park staff, selected using simple random sampling, who evaluated user satisfaction. Data were collected through interviews and questionnaires and analyzed using frequency and percentage statistics.
     The research results found that: 1) the plant information system was able to display details of 92 plant species; 2) the augmented reality application could present information on 6 plant species. The system evaluation by experts resulted in an average score of 4.75, indicating the highest level of appropriateness; and 3) the overall user satisfaction with the system had an average score of 4.26, indicating a high level of satisfaction.
