Abstract

Wetlands are among the most important ecosystems, that are valuable as sources, sinks, and transformers of a multitude of chemical, biological, and genetic materials. The interaction of man with wetlands is the first humanizing system initiated in the process of evolution and development of many civilizations. Societies have enjoyed an ancient association with wetlands and have learned to obtain multiple benefits- natural resources, amenities and environmental services.

In recent years, the wetland values are overlooked resulting due to population pressures and unplanned development. This has threatened the very existence of these vital ecosystems. In order to stem the tide of destruction, especially for wetlands located in urban setup suitable guidelines to assess the ecological integrity and effective monitoring programs are required. This includes collecting sufficient information on the various functions, components and attributes of wetlands to reduce the ongoing ecological imbalance. In view of this there is a need to periodically monitor these systems.

Water quality assessment of seven waterbodies located at various places in Bangalore urban district has been monitored for a period of twelve months, based on the findings of the study suitable restoration measures are suggested.

Ecological restoration and ecosystem management is an essential component of any habitat conservation. The management of wetlands has become important because these ecosystems are still being reclaimed or encroached for agricultural activities, aquaculture, for sewage disposal, etc. Hence for developing a site specific management plan for wetlands it is imperative to gather baseline information so as to understand the structure and functions of a wetland. In the recent past the wetlands of Bangalore are drawing considerable attention and concern because of their importance realised. The present paper attempts to identify some of the major threats, wetland face today and make suitable suggestions to draw the attention of to wetland biologists, conservationists, planners and policy makers.
