Colombia palm oil plantations reduce species richness by 47 percent – Government says oil palm agriculture to double to one million hectares by 2020

30 May 2018 (James Cook University) – With palm oil production exploding around the world, a new study of a leading producer has found ways to make the process easier on the environment.

James Cook University PhD candidate Lain Pardo studied the industry in Colombia – a country described as being on the “tip of the spear” in terms of burgeoning palm oil production.

The researchers used a new camera trapping technique across 2,000 square kilometres of the country’s most important palm oil production region and found that while palm oil plantations are not suitable for most mammals to live in, the situation could be improved.

“We found that the number and diversity of species differed significantly between oil palm plantations and their neighboring forests, with the number of species inside oil palm plantations 47% lower, on average, than in the forest,” said Mr Pardo.

He said that within the plantations, the number of different species declined as the number of cattle in the plantation rose, but species numbers were helped by the presence of dense undergrowth vegetation and proximity to forest.

These factors, and canopy cover, were also linked to an improvement in mammal diversity within palm oil sites.

The scientists looked at a savannah woodland system where much of the land was already in commercial use before being converted to palm oil.

Mr Pardo said unlike Southeast Asia, most of the land in Colombia converted for use as oil palm plantations had previously been pasture, not forest, and palm oil was not the primary driver of deforestation. But he said even when planted on savannah, oil palm plantations may have a devastating impact on wildlife.

“So, it’s still important to know what is going on ecologically in these areas. The Colombian government says land used to grow oil palms will double to about one million hectares by the year 2020. If unplanned, this expansion could result in a disruption of the ecosystem.”

Mr Pardo said the scientists recommended oil palm growers promote undergrowth vegetation and avoid cattle presence inside plantations, along with respecting designated buffer areas that allow for the conservation and restoration of riparian forests.

“The forests are the most important factor. Even secondary riparian forest makes an important contribution to sustaining wildlife across oil palm dominated landscapes in Colombia.”

He said the scientists understood that oil palm development provides social benefits in Colombia.

“Development in some areas is being partly driven by government incentives and corporate investments, and also in response to the end of a prolonged armed conflict, which has allowed access to previously inaccessible areas. So it’s vital to engage relevant stakeholders to balance socioeconomic and environmental goals. If Colombia follows our guidelines it has a great opportunity to produce palm oil in a more sustainable way, compared to Malaysia and Indonesia.”

Minimising the impacts of palm oil plantations


ABSTRACT: The rapid expansion of oil palm cultivation in the Neotropics has generated great debate around possible biodiversity impacts. Colombia, for example, is the largest producer of oil palm in the Americas, but the effects of oil palm cultivation on native fauna are poorly understood. Here, we compared how richness, abundance and composition of terrestrial mammal species differ between oil palm plantations and riparian forest in the Colombian Llanos region. Further, we determined the relationships and influence of landscape and habitat level variables on those metrics. We found that species richness and composition differed significantly between riparian forest and oil palm, with site level richness inside oil palm plantations 47% lower, on average, than in riparian forest. Within plantations, mammalian species richness was strongly negatively correlated with cattle abundance, and positively correlated with the density of undergrowth vegetation. Forest structure characteristics appeared to have weak and similar effects on determining mammal species richness and composition along riparian forest strips. Composition at the landscape level was significantly influenced by cover type, percentage of remaining forest and the distance to the nearest town, whereas within oil palm sites, understory vegetation, cattle relative abundance, and canopy cover had significant effects on community composition. Species specific abundance responses varied between land cover types, with oil palm having positive effects on mesopredators, insectivores and grazers. Our findings suggest that increasing habitat complexity, avoiding cattle and retaining native riparian forest–regardless of its structure–inside oil palm-dominated landscapes would help support higher native mammal richness and abundance at both local and landscape scales.
