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.

BASL asks govt. to abandon plan to raise retirement ages of CA and SC judges

… tells Prez such arbitrary change neither necessary nor desirable

The Bar Association of Sri Lanka (BASL) has urged President Anura Kumara Dissanayake to abandon the controversial plan to increase the retirement age of the judiciary, including the Court of Appeal and the Supreme Court.

In a statement issued by the BASL President Rajeev Amarasuriya and its Secretary Nalin de Silva, the BASL pointed out that the proposed increase of the retirement age of the judiciary would undermine the independence, integrity, dignity, and public confidence in the Judiciary, which is essential for the maintenance of the Rule of Law and democratic governance in Sri Lanka.

The text of the BASL statement: “The Bar Association of Sri Lanka (hereinafter referred to as “BASL”) notes with grave concern reports in the public domain that the Government is considering the introduction of an amendment to the Constitution to increase the age of retirement of Judges of the Court of Appeal and the Supreme Court.

It is the considered view of the BASL that the age of retirement of the judges of the Court of Appeal and the Supreme Court which has stood at 63 years and 65 years respectively from the promulgation of the 1978 Constitution, should not be changed arbitrarily and that such a change is neither necessary nor desirable.

To do so will result in the loss of public confidence in the integrity of the legal system and of the Government’s commitment to preserve and protect the rule of law and the independence of the judiciary. Members of the public are likely to question the motives of the Government in bringing in a Constitutional amendment solely for this purpose.

Your Excellency is no doubt aware that the cadre of the Judges of the Court of Appeal was increased from 12 to 20 Judges (including the President of the Court of Appeal) and that of the Supreme Court from 11 to 17 Judges (including the Chief Justice) by the 20th Amendment to the constitution certified on 29th of October 2020. With such enhancement, workwise, there cannot be a real requirement to extend the retirement ages of these judges.

Your Excellency is aware that altering the retirement age of judges of the apex courts would have to be done through a Constitutional amendment. For many years Sri Lanka’s Constitution has been subject to ad hoc amendments, sometimes in order to cater to the political needs of the government in power and often contrary to the interests of the rule of law, the independence of the judiciary and the judiciary.

Extending the retirement age of the sitting Judges of these Courts at this point of time is likely to be viewed by the public as a blatant attempt to interfere with the judiciary. We believe that to go ahead with such an ad hoc move will also be an affront to the Honourable Judges of those courts.

If the Government goes ahead with such a move it will set a dangerous precedent for future Governments too to introduce ad hoc amendments to the Constitution in respect of the functions of the Judiciary.

The independence of the Judiciary and the public confidence reposed in it, are indispensable pillars of the Rule of Law and the democratic framework of our Republic. In that regard, it is of paramount importance that the Judiciary must not only remain independent in fact, but must also be seen by the public to be wholly independent, impartial, and free from even the slightest perception of influence, favour, accommodation, or impropriety.

The Bar Association of Sri Lanka is therefore constrained, in the discharge of its duty to uphold and safeguard the Rule of Law and the independence of the Judiciary, to respectfully express its serious concern regarding any such proposed amendment, which is neither in the interests of the Judiciary and nor of the people.

In the circumstances, the BASL respectfully urges Your Excellency not to proceed with any proposed constitutional amendment seeking to increase the retirement age of the members of the Judiciary including Judges of the Court of Appeal and the Supreme Court.

We remain confident that Your Excellency will give due consideration to the importance of preserving and protecting the independence, integrity, dignity, and public confidence in the Judiciary, which is essential to the maintenance of the Rule of Law and democratic governance in Sri Lanka.”

Govt. declines to respond

A member of the Cabinet yesterday declined to comment on the BASL’s letter to President Anura Kumara Dissanayake. The Minister said that he wouldn’t comment for the time being.

New US tariffs proposed on 60 countries, including Sri Lanka

Published

12.5% additional duties on goods imported from Colombo

The US has proposed additional duties of 10% or 12.5% on imports from 60 economies, including Sri Lanka, over their alleged failure to curb trade in ‌goods made with forced labour.

The proposal made by US Trade Representative’s (USTR) office in terms of Section 301 unfair trade practices investigation to be released, news agencies reported, pointing out that the Trump administration was seeking to rebuild its emergency tariffs, which were struck down by a US Supreme Court decision in February.

The USTR said it determined that it would impose 10% duties related to ⁠the forced labour investigation on imports from Canada, Ecuador, the European Union, Indonesia, Mexico, Pakistan, Argentina, Bangladesh, Cambodia, El Salvador, Guatemala, Indonesia, Malaysia, Taiwan and Britain.

The trade agency said it would impose additional duties of 12.5% on the remaining 45 countries that were investigated.

“The failure of our most important trading partners to address the importation of goods made with forced labour is unacceptable,” US Trade Representative Jamieson Greer said in a statement. “This creates a dynamic where American workers are forced to compete globally on an unlevel playing field.”

According to the trade agency, the USTR found that Sri Lanka has failed to impose and effectively enforce a forced labour import prohibition.

The USTR noted that the results of its investigation indicate that the acts, policies and practices of Sri Lanka related to the failure to impose and effectively enforce a forced labour import prohibition are unreasonable and burden or restrict US commerce.

Accordingly, it has proposed to impose 12.5% additional duties on goods imported from Sri Lanka.

The USTR said it also was proposing a textile mechanism that would allow for a certain volume of apparel and textile imports ‌to ⁠enter the US at a reduced tariff rate, though the duties and volumes were not disclosed.

The announcement comes ahead of the July 24 expiration of a 10% temporary tariff imposed by the Trump administration on February 20, the day the Supreme Court struck down US President Donald Trump’s tariffs under the International Emergency Economic Powers Act.

On Monday, the USTR proposed ⁠a 25% duty on many Brazilian goods as a result of a Section 301 investigation into the country’s digital trade practices and preferential tariffs. The trade agency is also expected to soon unveil the findings of another major Section 301 probe into ⁠the buildup of excess industrial capacity in 16 trading partners, including China.

In the forced labour findings, the USTR said it would exempt from the tariffs a number of products, including energy, rare earths and certain ⁠other metals, beef, coffee, certain fruits and vegetables, pharmaceuticals, organic chemicals and aircraft parts.

The USTR said it would accept public comments on the proposed tariffs and other remedies through July 6, with a public hearing scheduled for July 7.
