The paper reports about the distribution of macrophyte in the wetland community of Hokera with special reference to macrophyte composition and vegetation analysis through phyto-sociological studies. The ecosystem supports diverse aquatic plant communities (emergent, rooted–floating leaf type, free-floating leaf type, submersed type) marked by striking variability in composition, frequency and extent of colonization. Several ecological factors, such as habitat loss related to siltaion, pollution, expanding agricultural activities and drastic hydrological fluctuations, have induced considerable changes in the dynamics and distribution pattern of sustained biota. The shift in macrophytic community structure is evidenced by the local extinction of Nelumbio nucifera and the near-disappearance of some economically important plants (Euryale ferox). The investigation of various aspects of wetland ecology of Hokera reveals that species composition has witnessed great variations. The shrinkage of the wetland area, once spread over 13.26 sq km has been now gradually reduced 5.6 sq km. The paper highlights the rapidly deteriorating environmental status of the Hokersar Wetland and stresses the need for its urgent ecological restoration with special reference to its macrophytes.
