Exotic plants UPSC NOTE


  • A group of ground forest team, including deputy rangers, watchers, and a protection watchers team, visited Chinnakkanal recently and interacted with local people and panchayat officials about steps to mitigate human-elephant conflict in the region.

  • Removing exotic plants from forest areas will help ensure food for wild elephants at Chinnakkanal in Munnar, says the study by the Kerala State Forest Protective Staff Organisation

  • In many areas in forests filled with exotic trees, no other plants are growing. 

  • Wild animals, including elephants, are unable to move through these areas. 

  • If these areas change to natural grasslands, it will ensure food and water for wild elephants.

Exotic plants

  • Exotic plants are those that are not native to the area in which they are growing

  • Some common exotic plants that are grown in gardens include bromeliads, orchids, cacti, and succulents

  • These plants often require special care, as they may not be accustomed to the local climate or soil. 

  • It is important to research an exotic plant before bringing it home, to make sure that it will be able to thrive in its new environment.

  • Exotic tree species grow faster than their indigenous counterpart. 

  • They can also be more profitable than native tree plantations in terms of timber. 

  • The exotic species like Eucalyptus species are fast growing and were introduced for paper and pulp production as well as oil production. 

  • Poplar and Prosopis juliflora were mostly planted for curbing desertification. 

  • These trees are also grown in commercial purpose for their high market value. 

  • These species are more dominant in comparison to the native species, as they easily acclimatize to the environment.

  • Growing exotic species is like walking on egg shells. 

  • Several of them turn out to be invasive and interfere with the delicate balance of ecosystems. 

  • Since these plants easily acclimatize with their surroundings, they spread like wild fire. 

  • Soon enough, we have higher population of exotic plants than native ones in our forests. 

  • This causes a cascade of changes where the organisms which are dependent on these native plants are adversely affected

Difference between Exotic and invasive species:

  • Exotic and invasive species are two types of non-native species.

  • Non-native species can be found in a second ecosystem apart from the ecosystem they evolved from

  • Non-native species spread by natural process or human activities. 

  • Most non-native or indigenous species are harmless. They are called exotic species.

  • When an exotic species becomes harmful to the ecosystem, it is called an invasive species.

  • The main difference between exotic and invasive species is that exotic species is harmless to the ecosystem whereas invasive species is harmful to the ecosystem.

  • Invasive species can be harmful the native habitats, natural areas such as lakes, forests, and rivers, agriculture, economy, and humans.
