Systematic surveys of climbing plants were investigated in the Sadhuragiri hills in the Southern Western Ghats of Tamil Nadu. Although, inventory and the study is primarily based on field surveys conducted throughout the hills, where native provided information on plant species used as medicine and the mechanisms of climbing of the climbers were studied. Several field trips were carried out in Sadhuragiri hills between Jan 2015 and March – 2016, Covering different seasons, in order to know the phenology of the plants and Intensive and extensive field surveys were made in Sadhuragiri hills and villages in Virudhunagar and Theni district viz. The data were collected through repeated field visits and the careful interaction with the village people and Paliyar tribes. A total of 102 plant species belonging to 59 genera comprising 28 families were identified. Convolvulaceae (13 species) the most species-rich plant families of climbers followed by Fabaceae (12 species), Oleaceae (11 species), Cucurbitaceae and Vitaceae each (7 species). Stem twinning formed the bulk (39%) of predominant climbing mechanism Twiners climber types followed by Tendril Climber (19%); Hook Climber (7%) and Prostrate Climber (7%); while root climbers were rare (2%). The Paliyar tribes are the main natives of these forests. During this survey documenting some climbing species used by tribes and rural peoples for all kinds of medicine and food additives were documented. This preliminary study focused on documenting most of the climbers used by the Paliyars tribes and rural communities in the southern Western Ghats of Tamil Nadu to facilitate conservation effort. There is a need to document the threats to local deciduous forests due to invasive climbers with increasing biotic interference and climatic change.
