{"abstract":"Deforestation in the Philippines leads to soil erosion, flooding, biodiversity loss, and climate change. In response, Saint Mary’s University Senior High School initiated the “One Tree, One Student” program, involving Grade 12 students and faculty in annual tree planting. This study used a quantitative and qualitative descriptive-correlational approach with a questionnaire to evaluate Ipil Cuneg residents’ perceptions of the program’s implementation issues and effectiveness, and to determine the relationship between them. The most prevalent issue identified was typhoons and other natural calamities impeding reforestation. Despite this, residents generally perceived the program’s effectiveness as Good. Statistical analysis revealed no significant relationship between perceived implementation issues and perceived program effectiveness. Residents suggested monthly checking and maintenance, planting trees near houses or in the community center, and increasing seedling numbers. The study concludes that while implementation issues, particularly natural factors, were observed, they were only slightly prevalent and did not diminish the program's perceived effectiveness. Residents acknowledged its contributions to forest cover, biodiversity, and environmental awareness. Sustaining the program through regular monitoring, quality seedlings, and stronger community and family participation, including organic maintenance, could enhance its long-term ecological and educational benefits.","abstract_source":"gemini_shortened","authors":["Angel Cassey Acapen","Atari Agcaoili","Gene Andrei Miranda","Yashi Pacimio","Krizzelle Claire Reprado"],"date":"2026-04-20","doi":"10.70838/pemj.550510","id":7671,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"1cbedd5dc9d7fafb621044c46d57c230be99745d2e485f7df6a722a060f9e021","schema":"scimatic-article/1","title":"Perception of Ipil Cuneg Residents on the Implementation Issues and Effectiveness of the “One Tree, One Student” Program of Saint Mary’s University Senior High School","volume":55}
