La invasión de plantas amenaza las funciones ecológicas y la biodiversidad de los ecosistemas ribereños. Se han propuesto diversas estrategias de manejo para preservar su vitalidad ecológica; sin embargo, se observan varios desafíos en muchos esfuerzos de gestión. Este estudio adoptó un enfoque socioecológico para comprender el paisaje ribereño a lo largo del río Pangdan, ciudad de Naga, isla de Cebú, Filipinas. Utilizando el método Belt Transect-Quadrat, se evaluaron los componentes ecológicos, a saber, índices biológicos y parámetros climáticos y de suelo; También se utilizaron entrevistas semiestructuradas con partes interesadas para recopilar datos sociales e históricos. Los resultados mostraron un gradiente en la diversidad de plantas, donde la región aguas arriba tenía la mayor riqueza de plantas nativas (N = 67,57%) y la región aguas abajo tenía la menor riqueza de plantas nativas (N = 5,41%). La intensidad de la luz y la temperatura surgieron como factores clave que dieron forma a las comunidades de plantas, y la riqueza de especies nativas y exóticas disminuyó a medida que estos factores aumentaron. Las propiedades del suelo dentro del rango examinado tuvieron efectos independientes mínimos sobre la diversidad de plantas. El análisis histórico reveló la prevalencia de actividades antropogénicas, a saber, extracción, minería artesanal e introducción de plantas invasoras. La disminución documentada de la diversidad vegetal y la prevalencia de especies exóticas plantean preocupaciones sobre la salud del ecosistema fluvial. Proporcionar datos de referencia valiosos y comprender el estado actual de la zona ribereña es crucial para desarrollar estrategias de gestión eficaces para los ecosistemas ribereños.
