Invasive Palm Threatens Java Rhino To Extinction

The last of Indonesia’s critically endangered Javan rhinoceroses have survived poachers, rapid deforestation and life in the shadow of one of the archipelago’s most active volcanoes. But an invasive plant is now posing a new threat to the world’s rarest species of rhino.

“Once the most common of the Asian rhinoceroses, the Javan rhino (Rhinoceros sondaicus) started its decline at least 3,000 years ago with the growth of human populations and increased hunting pressures. With its horn fetching $30,000 on the black market, poaching is considered the driver of much of its decline in modern times.

“As few as 58 Javan rhinos exist in the world today, and the species is quite possibly the rarest large mammal on earth. All are found in one small population in Ujung Kulon — a sprawling 1,200-square-kilometer (463-square-mile) national park on the westernmost tip of West Java and the island of Panaitan. In addition the rhinos, the park is home to dozens of other mammals, more than 270 species of birds and 57 rare plant species.

“But a single species of plant is threatening the park’s fragile ecosystem.

“The issue in Ujung Kulon is not deforestation — but an invasive species called the arenga palm,” said Elisabeth Purastuti, WWF’s Ujung Kulon leader.

“Once covered in old-growth forest, the cataclysmic eruption of nearby Krakatoa in 1883 wiped out much of Ujung Kulon’s primary forest cover, creating a patchy network of secondary forest where the rhino thrived.”


GR:  Conservation biologists have been saying that construction (total habitat elimination) and invasive species are the greatest threat to Earth ecosystems.  Though we now must place climate change in the number two spot, invasive species continue to be one of humanity’s greatest destructive achievements.  Read more:
