Invasive Species Threatening Haryana’s Forests

March 7, 2025

Haryana’s forests are under severe threat from invasive species, notably Lantana camara and Prosopis juliflora. These species have invaded approximately 89 square kilometres of forested areas, impacting biodiversity. Experts warn that without intervention, these invaders could permanently alter the ecological landscape of Haryana’s forests.

Invasive Species

Invasive species are non-native plants or animals that disrupt local ecosystems. In Haryana, five major invasive species dominate the landscape. Lantana camara is the most aggressive, followed by Prosopis juliflora. Other notable invaders include Saccharum spontaneum, Ageratum houstonianum, and Leucaena leucocephala. Together, these species cover about 12% of Haryana’s forests.

Impact on Biodiversity

The presence of these invasive species leads to a decline in native flora. Lantana camara competes for resources like nutrients and water, obstructing the growth of local plants. This competition disrupts natural ecosystems and hinders wildlife movement. Animals struggle to navigate through dense thickets, affecting their migration and access to water.

Economic Implications

The spread of invasive species has economic consequences. Management costs increase as the species proliferate. Agricultural productivity may suffer due to changes in soil composition and nutrient availability. This economic burden marks the need for effective management strategies.

Management Strategies

Experts recommend immediate intervention to control the spread of invasive species. Suggested measures include active removal, community engagement, and reforestation projects. Monitoring and educational campaigns can raise awareness about the ecological challenges posed by these invaders. The Haryana forest department is implementing mechanical removal and chemical applications as part of their management efforts.

Community Involvement

Engaging local communities in removal efforts is crucial. Community involvement can enhance the effectiveness of management strategies. Educating residents about the importance of preserving native flora can encourage a sense of responsibility towards forest conservation.

Future Directions

Ongoing research and monitoring are essential for effective management. The forest department plans to include surveys and removal in their annual plans. This proactive approach aims to mitigate the spread of invasive species and restore ecological balance in Haryana’s forests.
