 Why in news

  • Lantana being an invasive plant is known to envelop and ‘entangle other plants by forming a dense thicket, and spread on the forest floor as a scrambling shrub’. 

  • To help tackle this, a few organisations have been actively clearing the weed in certain pockets and employing locals to craft furniture, decor artefacts, and even sculptures.

Lantana

  • Lantana camara is a perennial shrub native to the American tropics and belongs to the Verbenaceae family.

  • With the ability to adapt to the changing climate, lantana can tolerate high temperature and moisture.

  • Lantana camara, a flowering shrub, among the world’s top 10 invasive species, was introduced to India as an ornamental plant in the early 1800s. 

  • Since, it has taken over entire ecosystems, and eaten into forests across the country. 

  • As per reports, ‘multiple hybrid varieties of lantana were brought to India and over the 200 years of its introduction, the varieties have hybridised and formed a complex’.

  • In forest areas at the National scale, total lantana infestation is 40% of India’s forests, more than four times the combined area of all tiger reserves in the country

  • It contains the toxins, Lantanadene A and B in the leaves, making it inedible for all herbivores, so significant biodiversity reduction occurs in forests and increasing human-wildlife conflict as animals are pushed outside forests.

  • In the Nilgiri Biosphere Reserve at the core of the Western Ghats, the area of dense infestation is around 2000 sq.km.

  • The first eradication plan for India was in 1916, in the forests of Coorg (Karnataka) and Benna (Mudumalai/TN), and all efforts since then have failed, both in India and around world
