In the recent years, several scholars working on Himalayan "Ecocrisis" reported that the wetlands in the region are suffering from severe biotic stress and that the damage ensuing is getting to the point of becoming irreversible. The Wetlands are intimately linked with the agro-ecosystems in the mountainous area of the Himalaya and the depletion has definite and obvious impacts on the overall socio-economic and agricultural scenario of the entire region. Macro invertebrate community responses to environmental changes are useful in assessing the impact of municipal, industrial, oil and agricultural wastes from other land uses on surface waters. There are four types of environmental changes, for which the patterns of Macrozoobenthos community structure changes have been documented, these are: Increased inorganic micronutrients, increased organic load, substrate alteration and toxic chemical pollution. The present Study was carried out from May to October 2008 to make a distribution assessment in Macrozoobenthic community of Hokera Wetland, which is an important ecosystem of international importance. Although a few species of Annelida were found to be dominant in terms of taxa[C1] and abundance of collection, Mollusca however, were poorly represented. Insecta, although represented by one Texan namelyChironomous sp., was abundant throughout the study period at all sites.
Key words: Hokera Wetland, micro zoo benthos community.
