Abstract

Rio Earth summit held in 1992 emphasized the need to conserve the biodiversity of the earth, especially of the tropics. The meaning of conservation involves thorough understanding of the flora and fauna on regional basis including those of wetland as form the bulk of the wetland flora and has immense functional values. Differences in the number of species and the identity of genera between these surveys indicate that macrophyte assemblages are still changing and are dynamic in different Ponds. Aquatic macrophytes exhibited a heterogeneous assemblage of sixteen species in the studied of Ponds were distributed in a variety of taxonomic groups of angiosperms, Of these Eichorniacrassipes, Vallisneriaspiralis, Hydrillaverticillata Ipomoea aquatica, Cynodondanctylon occurs throughout the year. During monsoon, floating species of aquatic macrophytes viz. Eichorniacrassipes, Vallisneriaspiralis, Hydrillaverticillata Ipomoea aquatica. Conversely, the monsoon varieties of aquatic macrophytes were succeeded by the winter emergent species viz. Lemna minor, Limnophillasessiflora, Otteliaalismoides, Nagas minor. The species occurs during onset of summer are Heliotropiumsupinum, Crozophorarottleri, Gnaphaliumpulvinatum, Glinuslotoides. Significant phytosocial association had been recorded among the different aquatic macrophytes. Hydrillaverticillata, Vallisneriaspiralis, chara sp., Nitellasp. were found to be association with others. Vallisneriaspiralis, Najas minor Potamogetonpectinatus, Ceratophyllumdemersum were found to be associated with other. Otteliaallismoides, Limnophillasessiflora, Valisneriaspiralis found to be associated with each other. The study represents the flora of Ranisagar and Budhatalab Pond of Rajnandgaon city of Chhattisgarh. Our aim is to study the especially focusing on the relationships between these resources and human health and wellbeing. Due to absence of river the “Bowl of rice state” irrigates the paddy field by ponds only in this region, which comes in the food chain of the human. An awareness of environment, its impact with religion orthodox promote quality environment for human survival of this area.
