Context |
● A recent study by the Kerala State Forest Protective Staff Organisation highlights the necessity of removing exotic plants such as Acacia mearnsii and eucalyptus from Chinnakkanal, Munnar, to ensure food for wild elephants. ● The region’s landscape is dominated by West Indian Lantana (kongini), hindering the growth of other species and limiting animal access. ● With 19 wild elephants, the area faces significant human-elephant conflict. |
Analysis of the news:
- A study by the Kerala State Forest Protective Staff Organisation (KSFPSO) suggests removing exotic plants like Acacia mearnsii and eucalyptus from forest areas to ensure food for wild elephants in Chinnakkanal, Munnar.
Exotic Plant Species |
What Are Exotic Plant Species? ● Exotic Plant Species: Exotic plant species, also known as non-native or alien species, are plants that have been introduced to a region or ecosystem where they are not native, often due to human activities such as trade, agriculture, or landscaping. ● Invasive Plant Species in India: Some invasive plant species in India include Lantana camara, Prosopis juliflora, Parthenium hysterophorus, Eichhornia crassipes (water hyacinth), and Chromolaena odorata (commonly known as Siam weed). |
- A ground forest team, including deputy rangers and watchers, interacted with locals and panchayat officials to mitigate human-elephant conflict.
- The state department emphasises the importance of converting areas with exotic trees to natural grasslands to provide food and water for wild elephants.
- West Indian Lantana (kongini) is a major problem in the Chinnakkanal landscape, inhibiting the growth of other species and restricting animal access.
- The region is home to 19 wild elephants, including two tuskers and various male and female elephants.
- An expert panel appointed by the High Court recommends reopening the elephant corridor from Anayirankal to Old Devikulam in Munnar to facilitate elephant movement and address human-animal conflict.
Issues Over Exotic Plant Species |
Issues Over Exotic Plant Species: ● Competition with Native Species: Exotic plant species often outcompete native flora for resources such as sunlight, water, and nutrients, leading to the decline or displacement of indigenous plants. ● Alteration of Ecosystem Dynamics: Invasion by exotic plants can alter ecosystem dynamics, disrupt food webs, and reduce habitat suitability for native fauna, affecting biodiversity and ecosystem functioning. ● Loss of Genetic Diversity: Exotic species introductions may lead to genetic homogenization and loss of unique genetic traits within native plant populations, reducing their resilience to environmental stressors. ● Increased Fire Risk: Some exotic plant species are highly flammable, increasing the risk and intensity of wildfires in affected areas, further threatening native vegetation and wildlife. ● Spread of Invasive Traits: Exotic plants with invasive traits can rapidly spread and colonise new habitats, forming monocultures and outcompeting diverse native ecosystems. Way Forward: ● Preventative Measures: Implement strict regulations on the import and trade of exotic plant species to prevent their introduction and spread into new environments. ● Early Detection and Rapid Response: Establish monitoring programs for early detection of invasive species and implement rapid response measures to control their spread. ● Restoration and Rehabilitation: Prioritize restoration efforts in areas affected by exotic plant invasions to restore native habitats and promote biodiversity conservation. ● Public Awareness and Education: Raise public awareness about the ecological impacts of exotic plant species and encourage responsible landscaping practices to avoid their introduction and spread. ● Research and Monitoring: Invest in research to better understand the ecology and behaviour of exotic plant species and their interactions with native flora and fauna, informing management strategies and policy decisions. |
