Document 10: Meghalaya: About 70% of the state is forested, of which is dense primary subtropical forest. The Meghalayan forests are considered to be among the richest botanical habitats of Asia. These forests receive abundant rainfall and support a vast variety of floral and faunal biodiversity. A small portion of the forest area in Meghalaya is under what are known as "sacred groves" (see Sacred groves of India). These are small pockets of an ancient forest that have been preserved by the communities for hundreds of years due to religious and cultural beliefs. These forests are reserved for religious rituals and generally remain protected from any exploitation. These sacred groves harbour many rare plant and animal species. The Nokrek Biosphere Reserve in the West Garo Hills and the Balphakram National Park in the South Garo Hills are considered to be the most biodiversity-rich sites in Meghalaya. In addition, Meghalaya has three wildlife sanctuaries. These are the Nongkhyllem Wildlife Sanctuary, the Siju Sanctuary, and the Baghmara Sanctuary, which is also the home of the insect-eating pitcher plant "Nepenthes khasiana" also called "Me'mang Koksi" in local language.

Document 12: Vietnam War: Beginning in 1970, American troops were withdrawn from border areas where most of the fighting took place, instead redeployed along the coast and interior, and US casualties in 1970 were less than half of 1969 casualties after being relegated to less active combat. At the same time that US forces were deployed, the Army of the Republic of Vietnam took over combat operations throughout the country, with casualties doubled US casualties in 1969, and more than tripled US ones in 1970. The post-Tet environment saw a rise in membership in Regional Force and Popular Force militias, now more capable of providing village security which the Americans could not under Westmoreland. In 1970 Nixon announced the withdrawal of an additional 150,000 American troops, reducing the number of Americans to 265,500. By 1970 the Viet Cong forces were no - longer southern - majority, and nearly 70% of units were northerners. Between 1969 to 1971 the Viet Cong and some PAVN units had reverted to small unit tactics typical of 1967 and prior instead of nation - wide grand offensives. In 1971 Australia and New Zealand withdrew their soldiers and U.S. troop count was further reduced to 196,700, with a deadline to remove another 45,000 troops by February 1972.
