February 6 , 2023 788 days 703 0
  • The Nodal Centre for Biological Invasions (NCBI) at the Kerala Forest Research Institute has come out with a management plan to eradicate Senna spectabilis.
  • It is the exotic invasive plant that is posing a severe threat to the State’s wildlife habitat.
  • Senna spectabilis is a deciduous tree native to tropical areas of America.
  • It grows up to 15 to 20 metres in a short period of time and distributes thousands of seeds after flowering.
  • The thick foliage of the tree arrests the growth of other indigenous tree and grass species. 
  • Thus, it causes food shortage for the wildlife population, especially herbivores.
  • It also adversely affects the germination and growth of the native species.
  • It is categorised as ‘Least Concern’ under IUCN Red List.
