Birds return to forest patches where Lantana was removed: Study

Published

on

Weeding out the invasive tropical American shrub, Lantana camara, appears to alter the composition of bird species in a forest, according to a new study conducted in Central India.However, the research was carried out over only three years. Long-term assessments of how birds and insects respond to the removal of this invasive species are needed, the study published in journal Restoration Ecology, stressed.

Lantanas arrived in India as a decorative shrub in the British colonial period but quickly took over several ecosystems as an invasive plant. The shrub can spread on the forest ground, climb over trees an a creeper and entangle with other native plants with ease.

The researchers focused on tropical dry forests, which don’t often get enough attention. “Peatlands or humid forests get more emphasis for their ability to sequester carbon,” Pooja Choksi, who has just completed her PhD at Columbia University and the lead author of the study, told Down To Earth.

Though dry forests sequester less carbon, people heavily depend on them, she added. Forest restoration by removing lantana was done for the convenience of people, Choksi highlighted. Local communities carried out the removal, the state forest department and a non-governmental organisation.

The team used sound recorders to assess how lantana removal in Madhya Pradesh’s Bichhiya, a critical tiger conservation site, impacted animals that vocalise in frequencies between the frequency range of 2-8 Kilohertz. Bioacoustics, which is the study of animal vocalisations, helps researchers monitor species.

They focused their research on three forest sites: Restored, unrestored, and those with little or no lantana. The team found no difference in species richness or the cumulative number of species across the sites.But differences emerged when they looked at the composition of bird communities or differences in species present at a site.

“What is interesting is that restoration for people’s livelihoods and convenience does not hurt biodiversity,” Choksi highlighted.

They also found differences in acoustic space use (ASU), which quantifies the amount of time soundscapes (animal sounds) are active in 24 hours. A higher ASU can indicate more diversity or abundance of vocalising species.

This change could be temporary, the expert speculated. When lantana is removed, it causes a shift in habitat. Some species will likely leave while others move in, she added.

“When such sudden changes happen, animal communities could be reorganising their community,” she said, adding that long-term studies could provide more concrete answers.

Choksi and her team are currently analysing the data to get a better understanding of the effects a change in soundscapes and the vocalising species composition could mean.

“We have seen a change in composition, but does that mean we are seeing more pollinators or more insectivores — we are currently assessing that,” she said.

Choksi plans to investigate the links between socio-ecological changes and restoration and how people perceive Lantana camara and forest restoration.

MEPA to crack down on marine polluters

… Warns would-be polluters of criminal prosecution, hefty fines and even blacklisting

The Marine Environment Protection Authority (MEPA) has warned that ship owners, operators and local entities responsible for marine pollution will face criminal prosecution, heavy financial penalties and possible blacklisting, MEPA Chairman Samantha Gunasekera said yesterday.

Gunasekera told The Island that Sri Lanka would no longer tolerate negligence and regulatory breaches that threaten the country’s marine ecosystems, coastal livelihoods and national economy.

“Any party that pollutes our seas—whether foreign vessels or local operators—should be prepared to face the full force of the law,” Gunasekera said. “There will be no room for excuses, delays or backdoor negotiations when marine pollution is involved.”

He said MEPA has intensified surveillance of major shipping routes, ports and environmentally sensitive zones amid rising maritime traffic through Sri Lankan waters, which remain among the busiest in the Indian Ocean.

SC delegation, headed by CJ Surasena, observes Indian Supreme Court in action

A 10-member delegation from Sri Lanka’s Supreme Court, headed by Chief Justice P. Padman Surasena, with Indian judicial officials

A 10-member delegation from Sri Lanka’s Supreme Court, headed by Chief Justice P. Padman Surasena, departed to New Delhi on the 11th of December, 2025, for an official visit to the Supreme Court of India as part of the ongoing official visit by the delegation to India.

The group was accorded a ceremonial welcome in the Court’s main hall, led by the Chief Justice of India (CJI) Surya Kant. CJI Kant told the assembled Judges that “the Indian judiciary was honoured to host” their Sri Lankan counterparts, expressing hope that the visit would be “meaningful and very constructive” and underscoring the “close emotional bonds” between the two countries.

The focal point of the programme was a special sitting of the Supreme Court. Chief Justice Surasena joined CJI Kant and Justice Joymalya Bagchi on the bench, presiding over the Court as a guest Justice. He was accompanied by nine other Supreme Court justices from Sri Lanka, who took seats in the well of CJI Kant’s courtroom to observe the day’s proceedings.

Supreme Court Bar Association President Vikas Singh formally greeted the delegation and praised Justice Surasena’s reformist efforts. Singh recalled the Sri Lankan Chief Justice’s own maxim, “If you want something you have never had, then you have got to do something you have never done”, highlighting the bold changes Surasena had introduced to modernise Sri Lanka’s Court system. Singh noted that these initiatives, particularly court digitization, were aimed at eradicating “the persisting problems of law delays” and streamlining case backlogs.

The Sri Lankan Judges spent the morning observing live Supreme Court proceedings in CJI Kant’s courtroom. This first-hand exposure to Indian court operations formed a key part of the programme’s judicial engagement. During the hour-long session, the visiting justices witnessed a range of cases on the Supreme Court’s roster, with Justice Surasena and the delegation following arguments from the front. The experience was designed to be immersive and following the hearing the Sri Lankan Judges were briefed on India’s own initiatives towards a digitalised court system, e-filing and case management systems.

The official programme then shifted to capacity-building and information exchange. In the early afternoon, Indian Supreme Court officials gave the Sri Lankan delegation detailed briefings on India’s technological initiatives. Court registrars demonstrated the e-filing system and other e-initiatives implemented by the Supreme Court of India. Additional presentations outlined the Court’s new case management systems and administrative reforms. These sessions highlighted how digital tools and better case-listing procedures have been used in India to increase efficiency. The Sri Lankan judges asked questions about India’s experience with electronic court records and the integration of technology in daily judicial work, reflecting their own interest in similar reforms back home.

The visit underscored the growing collaboration between the Indian and Sri Lankan judiciaries. Throughout the proceedings, both sides emphasised their shared legal traditions and mutual respect. As Chief Justice Surasena noted during the sitting, India is Sri Lanka’s “closest neighbour,” and historic links, even dating back to ancient epics, form the backdrop for today’s judicial dialogue. CJI Kant remarked that having the chief justices of two vibrant democracies together on the bench was a “significant moment” for the rule of law.

The Sri Lankan delegation continued its programme in Delhi on 12 December with a visit to the Delhi High Court and its International Arbitration and Mediation Centres. The exchange visit is expected to deepen judicial cooperation and provide practical insights for both courts. Officials on both sides say the engagement aimed at sharing best practices in court administration, reinforce legal ties and support ongoing reforms aimed at reducing case backlogs and delays.
