Environmentalists have lengthy frightened concerning the adverse impacts of oil palm cultivation, particularly on biodiversity when forests are burned and changed into plantations.
Now researchers say there’s a answer that might mitigate the injury.
Establishing forests or “tree islands” in giant oil palm farms may also help restore biodiversity and ecosystems by aiding the pure regeneration of native bushes, their research suggests.
Rising worldwide demand for palm oil triggered huge forest destruction in Indonesia and Malaysia – chargeable for 85 per cent of world palm oil manufacturing.
These plantations have been a disaster for endangered animals, akin to tigers in Indonesia’s Sumatra. Additionally they worsen conflicts with native Indonesian communities on conventional land rights.
In 2023, with the manufacturing of 47 million tonnes of crude palm oil, Indonesia grew to become the main palm oil exporter on the planet. However up to now twenty years, the nation has additionally misplaced 3 million hectares of pure forest areas, due to the unfold of oil palm plantations.
Printed this month within the journal Science, the research says the intensive conversion of Southeast Asian pure forests into plantations of African oil palm (Elaeis guineensis Jacq.) has led to alarming losses of biodiversity, ecosystem functioning and evolutionary historical past.
The researchers say it’s important to guard the remaining forests to preserve their wealthy, tropical biodiversity.

Our research demonstrates the potential of tree islands to rework biodiversity-poor agricultural lands into biodiversity-enriched ecosystems, providing a promising restoration technique for oil palm landscapes.

Within the research, the researchers appeared at how ecological restoration contributes to the restoration of biodiversity in oil palm agricultural areas in Sumatra. The researchers strategically planted bushes to arrange 52 tree islands of various sizes and variety ranges to learn the way the restoration methods affect biodiversity within the oil palm agricultural space.
“The primary implication of our research is that it helps the usage of tree islands, strategically planted patches of native vegetation inside agricultural landscapes, as a viable strategy to restoring plant variety in oil palm landscapes,” mentioned Gustavo Paterno, an creator of the research and postdoctoral researcher at Göttingen College in Germany.
The researchers noticed that six years after being arrange, tree islands hosted a broad vary of native species, together with greater than 2,700 woody plant species.
They are saying creating giant and numerous tree islands is necessary for conserving “uncommon, endemic, and forest-associated” plant species in oil palm agricultural areas.
Tree islands pace up the pure revival of native bushes by serving to the unfold of seeds by birds and wind, based on the research. This course of improves biodiversity, necessary for creating resilient ecosystems that may resist local weather change.
“Our research demonstrates the potential of tree islands to rework biodiversity-poor agricultural lands into biodiversity-enriched ecosystems, providing a promising restoration technique for oil palm landscapes,” mentioned Paterno.
“Primarily based on these outcomes, we suggest the institution of enormous tree islands with a excessive preliminary variety of planted tree species to advertise biodiversity restoration inside typical oil palm plantations,” he instructed SciDev.Web.
Nevertheless, Johny Tasirin, from the school of agriculture on the Indonesia-based Sam Ratulangi College, believes the answer has limitations.
“Total, the native crops, birds, and bug variety might enhance, however I nonetheless doubt about recovering the big mammalian species that are a typical a part of pure forests in Sumatra,” he instructed SciDev.Web.
