Sinharaja Forest Reserve – Biodiversity hotspot in Sri Lanka

There is a great Rainforest in Sri Lanka that has not been touched by humans since the pre-Gondwana era when all the continents were one. It is the Sinharaja forest reserve. In this article, we will delve into the lush, vibrant, and enigmatic world of this UNESCO World Heritage Site.

A popular opinion regarding how the forest got its name is that lions have been alive in Sri Lanka and India in the past, and the last lion in Sri Lanka lived in this forest spreading its dominance, and because of that, it was later called Sinharajaya.

Geographical Significance

Sinharaja’s geographical placement, shielded by the central mountains and the Indian Ocean, results in heavy rainfall. This abundant precipitation sustains a thriving ecosystem, making it a Tropical Wet Evergreen Forest.
There are 5 mountains with a height of more than 600 meters. Among them, the highest place is Hinipitigala mountain which is located at the height of 1171 meters.

Biodiversity Hotspot

It is well acknowledged that the Sinharaja rainforest in Sri Lanka is one of the world’s biodiversity hotspots. An incredible variety of plants and animals may be found inside its borders. More than half of Sri Lanka’s endemic species, including rare amphibians, reptiles, and orchids, are found there.

However, the forest’s richness of life is unsurpassed by many more substantial rainforests and also, Sinharaja is a haven for wildlife lovers. It’s home to the secretive Purple-faced Langur and the colorful Sri Lankan Frogmouth.
Rainfall in the wooded region ranges from 300 to 6000 mm on average. Additionally, the region’s average yearly temperature is between 18 and 27 degrees Celsius. This region has abundant rainfall, which has resulted in the creation of numerous stunning waterfalls. Brahmana Falls, Duwili Falls, and Ura Vetunu Falls are a few of them.

Exquisite Plant Life

In this bio-diversity ecosystem, the Sinharaja forest reserve has a density of about 240,000 plants per hectare. Among the 340 species of plants with timber value found here, 192 species of plants are endemic to Sri Lanka. Out of those 192 plant species, 15 are found only in the Sinharaja. Also, about 75% of the plants here are endemic to this country.
Sinharaja’s flora is a testament to nature’s artistic brilliance. Towering dipterocarp trees form the canopy, while the forest floor teems with endemic plants like Sinharaja fern and Sinharaja orchid.

Below are the main canopy layers of the plant system located in the Sinharaja rainforest.

  • The emergent layer

The emergent layer is the forest layer about 45 meters above the forest floor, home to eagles, monkeys, butterflies, insects, and bats. This layer consists of tall trees like Shorea congestiflora, Sorea stipulates, and Shorea affinis.

  • Canopy layer

At about 35 meters above the ground, plants such as Shorea distinct and Shorea megistophylla form the primary canopy layer. This layer simultaneously provides a habitat for animals such as monkeys, flying squirrels, bats, tree frogs, ants, beetles, and flies.

  • Sub-canopy layer

The sub-canopy layer at a height of about 25 meters is home to a large concentration of insects. The plant species in this layer protect the exposed soil to regenerate the forest and create a micro-habitat.

  • Ground layer

The ground layer, known as the lowest layer, consists of many rare and endemic herbaceous plants.
