African forest elephants are vanishing at an alarming rate, and scientists have discovered this isn’t just bad news for elephant conservation – it’s causing ebony trees to disappear too.
A UCLA-led study reveals forest elephants are essential for ebony tree survival. In regions where elephants have been hunted to extinction, researchers found 68% fewer ebony saplings compared to areas where elephants still roam. This finding connects two seemingly separate conservation issues: declining elephant populations and struggling rainforests.
“People think, ‘Oh, it’s a shame these magnificent creatures are threatened,’ but what they don’t understand is that we won’t just lose elephants, we’ll also lose the ecological functions they provide,” said Thomas Smith, senior author of the study and a UCLA distinguished research professor.

The elephant-ebony relationship works in a surprisingly simple way. Elephants eat ebony fruits, carrying the seeds miles away in their digestive tracts before depositing them intact on the forest floor surrounded by dung. This elephant dung acts as a protective shield, preventing rodents from eating the seeds and giving them a better chance to sprout.
Poaching has driven an 86% decline in forest elephant populations over the past three decades. Elephants are already absent from at least 65% of the ebony trees’ historical range in the Congo Basin.
The problem extends beyond just fewer trees. Genetic testing showed ebony trees in elephant-free areas are becoming more inbred. Without elephants to carry seeds far away, new trees grow clustered near parent trees instead of mixing with different gene pools miles away. This reduced genetic diversity makes the trees more vulnerable to disease and climate change.
West African ebony, prized for its deep black heartwood, is used in piano keys, guitars, and carvings. These slow-growing trees take about 50 years to begin reproducing and 60 to 200 years to fully mature.
Vincent Deblauwe, the study’s lead author, worked closely with Indigenous Baka people who first identified the connection. “The Baka explained that they had seen ebony seedlings germinating in elephant dung,” said Deblauwe. This local knowledge proved crucial to the research.
In African rainforests, 80-90% of trees rely on animals to disperse their seeds. Forest elephants are considered “gardeners of the forest” because they shape forest composition by favoring slow-growing trees with dense wood, which store more carbon.
The Ebony Project, a partnership between Taylor Guitars, UCLA’s Congo Basin Institute, and local communities, has already planted 40,000 ebony trees and 20,000 fruit trees. But long-term conservation requires protecting the remaining elephant populations.
“We are really on the precipice of extinction of forest elephants and the extinction of those ecological processes that regenerate forests,” Smith warned. “This is kind of code red. We need to really act now to preserve forest elephants.”
The research underscores how ecosystems are interconnected – when one species disappears, many others can follow, potentially triggering a cascade of ecological and economic consequences that reach from rainforests to musical instruments.
