Habitat Conservation and Improvement -- Grasslands
Grasslands and waterholes play key role in the management of precious wildlife of CNP. Grasslands are being converted into shrublands and forests resulting in the decrease of grassland area from 20% in 1970s to about 5% in recent years. However, the invasion of Mikania micrantha (Banmasa i.e. forest killer or mile a minute) is becoming more and more aggressive to grasslands and other ecosystems.
Grassland ecosystem is very dynamic. It is readily affected by floods, fires, grazing and manual cutting. The increase in the Saccharum spontaneum (kans) type of grassland is considered to be the highest quality habitat for wild herbivores especially the rhinoceros and the deers. It is also a major source of elephant fodder on one hand and a preferred raw material for paper pulp.
Break-up tall grass stands into patches work of tall grassland and short grassland is crucial for wildlife conservation but the work is challenging.
Khagendramalli, Chappachuli, Amrite, Padampur, Dumaria, Jarneli, Sukebhar, Bhimle, Budhirapti, Buddanagar, Kachuwani, Ghatgain/ Lamital, Devital and Khoria Mohan are the major grasslands of Chitwan Natinal Park. Lack of record of grasslands and their characteristics, and invasion of grasslands by unwanted species are the major issues in the grassland management.
