Padula Mancina is a swampy and marshy zone on the west of Montesano Salentino, in the direction of Ruffano, which is now a remnant of a larger and largely reclaimed wetland. It consists of a pond with a surface area of ​​2.5 hectares. The area is prone to periodic flooding due to the collection of rainwater that from here conveys through certain canals and results as a of particular natural interest. Recent surveys have allowed a census of the fauna and flora species existing in the area. The flora is mainly composed of marsh reeds (Arundo donax, Phragmites australis) along with the white morning glory (Calystegia sepium), the lisca lacustre (Schoenoplectus lacustris), the water iris and Typha (Typha latifolia). There are also the Mediterranean shrubs and a species of fern, Marsilea strigosa.
