When Invaders Move In On Batu Caves (And They Have)

From flowering plants to butterflies , invasive species are taking over Batu Caves. This alarming threat to the fragile limestone ecosystem needs addressing.

WE HAD trekked up Batu Caves for about 10 minutes when botanist Dr Ruth Kiew turned to me and asked, “Can you see the difference in the vegetation?”

“Between limestone and non-limestone vegetation, you mean?”

“Yes.”

I scanned the plants before me. This was pre-pandemic times and I had been researching limestone species from lists provided by Kiew.

Discoveries Support Urgent Protection for Batu Caves

Scientists make new findings, not necessarily all good, in the iconic Batu Caves, confirming its status as a natural treasure.

FOR THE millions of tourists who thronged Batu Caves in pre-Covid-19 times, and even for the residents who live nearby, the limestone hill is known only for its colourful Hindu temple and the Thaipusam festival.

Overshadowed is the hill’s scientific importance. Batu Caves is actually the best-studied limestone hill in Southeast Asia with many valuable natural history characteristics which are threatened.

In fact, is there even anything of scientific value left to conserve? The answer is a resounding “yes” according to a recent scientific expedition.
