The Kole wetland, one of the largest, highly productive and one of the rice granaries of Kerala, has been declared in Ramsar convention for protection. Ponnani Kole, the study area, is situated in south-west of Malappuram and north-west of Thrissur districts, is the northern most extension of the Vembanad Kole Ramsar site. However, to the best of our knowledge, no solemn attempts were made to study the ecological impacts of these Kole wetlands especially emphasising biodiversity, physico chemical characters and human dependence. The present study is based on field survey and laboratory analysis of selected species. The study reveals the significant variation in stress physiology among plants grown in the area of high ecosystem diversity. It is also noticed, a massive destruction of the vegetation in the Koleland are very high due to natural and anthropogenic activities. Soil erosion also very high in Koleland and this leads to declination of vegetation as well. Study elucidated the physiological changes and related tolerance mechanism that occur in three plants according to the ecological variations during different seasons.
