The study was conducted from November 1998 through October 2003. The Kole wetland is one of the largest and highly productive wetlands and it is one of the most threatened wetland in the state.

Mumbai, July 16 With the organised efforts of the city's Tree Authority, several rare trees in the city are set to get nameplates. These trees will get a bright green metal plates identifying them by their common and scientific names, in English as well as Marathi.

Dinitrogen (N2) fixation is widely recognized as an important process in controlling ecosystem responses to global environmental change, both today and in the past; however, significant discrepancies exist between theory and observations of patterns of N2 fixation across major sectors of the land biosphere.

Beijing's notoriously smog-choked environs are soon to be gifted an oasis of respite, courtesy of the Olympic Games. The largest public green space in the country, a 680-hectare Olympic Forest Park will soon open its oxygen-laden doors to the public.
The park is being billed by the authorities as a green lung for what is one of the world's most polluted cities. Built at the cost of 7.7 billion yuan ($1.12b) over a three-year period, the Forest Park is located at the northern end of the south-north axis around which the Olympic village is constructed.

The present study gives an idea of changes taking place in pollen characteristics of Delonix regia and Peltophorum inerme under the influence of air pollution. Pollen germination, viability, size and pollen tube length were the parameters studied. The reduction in pollen viability and pollen tube length was more significant in P. inerme than D.

The need for the integrated Kashang HEP, located in the Sutluj basin which stores 9412 MW power potential being 46% of the total hydro power potential of the state, has therefore been considered in context of power shortage in Northern Region. The discharge characteristics of Kashang and Kerang khads is also favourable with unique parameter i.e.

Here the authors present results of the first multi-decadal experiment to examine the impacts of chronic, experimental nitrogen addition above ambient atmospheric nitrogen deposition. This total input rate is comparable to terrestrial nitrogen deposition in many industrialized nations. The researchers found that this chronic low-level nitrogen addition rate reduced plant species numbers by 17% relative to controls receiving ambient N deposition.

The Forest Department of BTC has undertaken initiatives for conservation of forest resources in the BTC region by holding several awareness campaigns, seminars, workshops and motivation programmes.
