Alien Invasive Plants

Alien Invasive Plants:

A new study has found that several alien invasive plants growing together can have a detrimental effect on the biodiversities in tiger habitats in Kanha Tiger Reserve.

  • The research paper has deciphered many negative impacts of multiple co-occurring alien plants on biodiversity and what it means for conservation in the era of global changes.
  • India’s biodiverse ecosystems are threatened by a variety of alien plants like Lantana Camara, Parthenium hysterophorous, and Prosopis juliflora introduced during British colonisation.
  • Co-occurring invasive plants like Ageratum conyzoides, and Pogostemon benghalensis cause ecological homogenisation in invaded regions.
  • Multiple alien species together affected soil nutrients, which may have depleted the richness of diverse plants.
  • Invasions might slowly deplete the native plant populations and might lead to diseases in the herbivores.

Kanha Tiger Reserve:

  • It is nestled in the Maikal range of Satpuras in Madhya Pradesh, the heart of India that forms the central Indian highlands.
  • This Tiger Reserve stretches over an area of 940 square km in the two districts Mandla and Balaghat in the state of Madhya Pradesh.
