pH is an important parameter in assessing drinking water quality. The value of pH is a number between 0 and 14, with 7 being neutral. Values below 7 indicate acidity and those above 7 indicate basicity. The acceptable range as per the Bureau of Indian Standards is 6.5 to 8.5.
Conservation and Sustainable Management of Wetlands in key areas in the Nilgiris is a prime interest area of Keystone. Wetlands of the Nilgiri region are unique, unlike wetlands in general – these are small sized hill wetlands, life giving in nature…habitat for a variety of wildlife, flora and meet the needs of the people.
These wetlands are fragmented in small random patches – with underground connectivity of water channels. There are no dramatic landscapes that lead to the wetland zones, it is sometimes found in the most unexpected places – and therefore has been taken for granted and their functions and roles significantly underestimated.
In the upper areas of Mukurti National Park – wetlands occupy central places as they are the corridors of the streams. They form belts around the streams and contribute to the flow – bringing in water and other nutrients from the side slopes and grasslands.
Over the years,there has been an apparent destruction of these valuable habitats, the scale of which is unprecedented in human history. Large wetlands in the Nilgiris also suffered from the same fate. With this knowledge and an earlier understanding of the importance of water resources for he indigenous people of the Nilgiris, we set out on an early wintery morning to study these wetlands..
We decided to conduct an intensive rapid survey and mapping of crucial wetland habitats, taking into account ecological aspects, socio-economic situation of stakeholders within the wetland home-range and economic activities that are on-going at present. Simultaneously, we conducted several awareness generation programmes that included walks, designing posters and booklets and speaking more about them to people who have depended on these resources for ages.We also started a process of dialogue and advocacy with the Government on how to declare these wetlands as important conservation areas and initiate legal steps towards it.
As an implementation initiative, we developed local wetlands conservation and management plans in five critically important zones of the district. The truth remains that with increasing population pressure and immense problems of degradation, wetlands are usually the first casualties. But a greater fact came out through the survey and that is of the high degree of importance indigenous people attach to the resources and their willingness to protect the wetlands remains exemplary….You too.. Be a Voice for the Wetlands
The Thalaikundah wetland is located next to a National Highway (Ooty-Mysore) and is subject to pressure from locals and tourists. The time slider lets us explore any changes in land cover in the last ten years.
The Ralliah dam is one of the important sources of water for the Coonoor town. It was built in the 1930s. The catchment of the dam is mostly forest land dominated by exotics. There are wetland patches that serve to supply water to the dam throughout the year. Can you spot any changes in the land cover that are interesting?
