In India plantations of exotic tree species like populous debtoides, Acacia spp., Eucalyptus spp., Laucaena leucocephala and Prosopis juliflora etc were promoted to meet the increasing industrial and fuel demand. The exotic acacia and eucalyptus were introduced in Nilgiris Hills in 1858 where E. globules was planted along with E. Robusta.
Conservation is a tricky thing. It's about finding the balance between the needs of wildlife and mankind. It's about preserving what exists, saving what's diappearing, and encouraging what's naturally developing. WWT's (Wildlife & Wetlands Trust) work in Koshi Tappu, Nepal is a fascinating project that requires careful dedication to all these balances. In a nutshell, Koshi Tappu is a wetland that has been fished by local communities for generations upon generations.
Invasive weeds have become a major environmental concern at local, national, regional and global level. Very recently, the authors have noticed an exotic temperate weed in the Mussoorie hills i.e. Stevia ovata. It is spreading in moist, South-West hill slopes.
One of the major underlying causes for increased biological invasion is the growth and development of world markets facilitated through globalization, and the booming intercontinental trade of live flora and fauna.
The protected areas of Himachal Pradesh in the Indian Himalayan Region are facing high anthropogenic pressure due to grazing rights. Habitat degradation coupled with overexploitation of sensitive biodiversity elements has caused habitat alteration and rapid decrease in their populations.
"Neighborhood Watch - Early Detection and Rapid Response to Biological Invasion along U.S Trade Pathways" identifies the crucial measures required to improve biosecurity measures at and around control points in international trade, especially U.S. ports, as well as a possible funding mechanism based upon the

After centuries of colonization and trade, South Africa is now home to alien species from Australia, Europe, Asia, and the Americas. As an antidote, a pioneering program called Working for Water (WfW) has cleared about 1 million hectares of invasive species in the past 15 years.
The bicentenary of Charles Darwin's life and work reminds us that the great biodiversity on Earth underlies natural selection, selective breeding, and the biotechnologies required to provide humanity with food, fiber, fodder, and fuels.
