Why in news
A study in the journal Catena revealed that Kaziranga National Park's vegetation evolved from tropical dense mixed forest to grasslands over 3,000 years due to climate change and human pressure.
Background
Scientists analyzed soil samples from the Sohola swamp in Kaziranga National Park. The study found a 3,000-year transition to open landscapes, which facilitated the growth of large herbivore populations like the Indian one-horned rhinoceros.
Facts for Prelims
- PlaceSohola swamp is a specific site within Kaziranga National Park.
- EnvironmentKaziranga hosts more than 70% of the world's one-horned rhinoceros population.
- EnvironmentMimosa is identified as an invasive species requiring management in the park.
- FactThe vegetation transition in the park occurred over a period of 3,000 years.
For Mains
