The western ghat ecology expert group identified 25 ecologically sensitive areas in kerala this classification is based on the criteria of sensitivity scores of different regions . the meeting of the WGEEP committee will be held in thrissur in may 3 -2011 . The union ministry asked the panel to estimate the status of the ecology and earmarked this areas as ecologically sensitive zones for notification. The committee will also take the precautionary measures for protecting and rejuvenating the ecologically sensitive areas in the western ghat regions .
The committee will submit a detailed project report to the union ministry on june 5 -2011 . the studies reveals that Attapadi, Athirappally, Sholayar, Malakkapara, Vythiri , Nelliampathi hills , Konni and Ranni are on the list of the committee.
In munnar the places near to forest stretch will be considered as sensitive areas so they left untouched. The tourism developments permitted only in the less sensitive areas . The WGEEP committee will also discuss about the controlling of ecotourism activities in the western ghat areas .
Ecotourism is a fast growing tourism sector in kerala. What is mean by ecotourism ? . , which means the development of an area in tourism sector without disturbing the natural resources . Several locations in kerala are very much known for their natural beauty.
The most famous ecotourism sector in kerala is western ghats. 12 wildlife sactuaries and national parks are part of kerala. You can experience a rich biodiversity . Ecotourism in kerala offers mountaineering , trekking , bird watching , boating etc. The famous attractions in kerala includes munnar, Boothathankettu, Athirappally-Vazhachal, Nelliamapathi, Kuruva islands, Tirunelli, Ravipuram etc.
Grassland ecosystems have herbaceous plant dominated by the species of poaceae , the grass species .associated with grasses are several herbaceous dicotyledonous species , mainly legumsae, which play keys role in nitrogen fixation. Amongst the well known grassland biomes are the extensive prairie in the north America and steppe in Russia. The annual rainfall in grassland region is too low when compared with forest and much higher that the rainfall than desert areas. Grazing and fire play an important role in the destruction of grassland .the height of grassland vegetation is highly variable, ranges from centimeters to half meters. One of the remarkable aspect of grassland is its extensive root system .the productivity of grassland depends on rainfall.
The living world offers direct and indirect benefits to humans. Biodiversity is the source of food, drugs, medicines, rubber , timbers and fibres .the diversity of organism also provide different ecological services free of charge that are responsible for maintaining ecosystem health. Biodiversity favours human life by serves as a source of new crops, it will provide the improved varities of plants and animals. It will help to produce biodegradable pesticides. Biodiversity provide different types of drugs and medicines .some useful drugs taken from plants includes morphine, taxol etc. the traditional medicines are prepared from plants. Biodiversity have great aesthetic value. The aesthetic aspects consists of ecotourism, bird watching , gardening etc. through out the human history people have related biodiversity to the very existence of human race through culture and religious advantages. Biodiversity is essential fro the well being of ecosystems and their sustainable utilization. The ecosystem services includes climate control, oceanic systems, natural pest control etc.
Biodiversity may change with latitude and altitude. When move from high to low altitudes the diversity in organisms increases .in temperate regions the climate is not suit for the growth of plants. The tropical regions have the conditions for the growth of plants. favorable conditions favour speciations and it will produces large number of species .for example we consider the number of vascular plants in tropical forests , it may changes from 110 to 230 , where as in temperate regions it may changes from 20 to 40 . we can conclude that when we move from lower to higher altitudes , the species diversity decreases. Every 1000 m rise in height will reduce temperature by 7 degree celcius. This drop in temperature cause seasonal changes .
