Question 4

Where can I find rattan palms in Sri Lanka?

Rattan palms, including Calamus species, are most commonly found in the moist lowland and sub-montane forests of Sri Lanka's wet zone. Protected areas such as Sinharaja Forest Reserve and associated buffer zones represent some of the best remaining habitat for these plants.

Question 5

Accepted Answer

Sri Lanka's combination of varied climate zones, altitudinal range, and geographic isolation has produced an exceptionally rich and distinct flora. Around 26 percent of its approximately 3,400 flowering plant species are found nowhere else on Earth, making botanical documentation and forest conservation critically important.
