Context

Herbs dominate the flowering plants in western Assam’s Raimona National Park, one of two newly-upgraded protected areas in the State.

National Parks in Assam: Raimona, Dehing Patkai, Kaziranga, Manas, Dibru-Saikhowa, Nameri and Rajiv Gandhi Orang National Park.

Key-highlights of the Study

  • A total of 24 species of flowering plants were recognised as invasive.

Invasive species

  • An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.
  • The five dominant families are 
    • Poaceae
    • Phyllanthaceae
    • Orchidaceae
    • Malvaceae
    • Rubiaceae
  • The study yielded a few lesser-known species such as Begonia nepalensis, Osbeckia stellata and Strobilanthes anisophylla, a plant that had not been recorded within the political boundary of Assam earlier.
  • Of the 33 species that were put in the RET (rare, endangered and threatened) category, 15 were found to be endangered, five vulnerable and one rare — Flacourtia jangomas.
  • A total of 12 species were placed in the “least concern” category.

Raimona National Park

  • Raimona, known earlier as Ripu Reserve Forest, was notified in June 2021 as the sixth national park of Assam.
  • It is located in Kokrajhar district of the Bodoland Territorial Region (BTR) in lower Assam.
  • Kaziranga National Park and Manas National Park, two of the five notified before it, are World Heritage Sites designated by the UNESCO.

Verifying, please be patient.
