You may learn more about the biodiversity of our Gunung Leuser National Park by joining our jungle trekking in Bukit Lawang, North Sumatra. We usually include both daytime and nighttime hikes in our jungle trekking packages. Our herping tour, which follows a day of hiking to search for wild and semi-wild orangutans in Bukit Lawang, is the second most popular activity for snake enthusiasts and herpetologists.

Looking For Semi-wild and Wild Sumatran Orangutan.

Since most of the jungle trekking in Bukit Lawang focuses on semi-wild orangutans—whose behavior also influences the behavior of wild orangutans in Bukit Lawang—the wild Sumatran orangutan there is generally still little known. There is extremely little chance that you will come across true wild orangutans in Bukit Lawang that do not exhibit adaptive behavior. We are always up for the challenge of searching Bukit Lawang for the actual wild Sumatran orangutans through our jungle trekking, particularly to witness and understand their true-wild behavior, which keeps them perched on treetops and even makes it harder to spot them because they never interact with humans (rare interspecies interaction).

Conservation Based Ecotourism: Responsible Jungle Treks and Tours.

In a workshop on identifying key biodiversity areas held in Banda Aceh, it was revealed that at least 243 fauna and flora are threatened with extinction in Sumatra. The endangered biodiversity consists of 29 species of birds, 38 species of mammals, 8 species of amphibians, 12 species of reptiles, 14 species of fish, and 142 species of plants. One level of threat to the species is the ongoing destruction of habitats or forests.

From the results of the analysis, it is estimated that the forests of Sumatra, especially the lowland forests, will be severely damaged if significant conservation actions are not carried out to inhibit, or even stop the rate of forest destruction, 1.4 million hectares per year. Because of that, it is necessary to identify biodiversity areas to be used for conservation-based ecotourism. Sumatra has a hotspot, namely an area that has a high level of biodiversity but also faces a high level of threat. There are 24 hotspots in the world, two of which are in Indonesia, namely the Sundaland and Wallacea hotspots. Sumatra is included in the Sundaland hotspot which shows that Sumatra has high diversity but is also accompanied by a high level of threat to biodiversity.

In order to avoid having a detrimental influence on the ecosystem, it is crucial to conduct jungle trekking and tour activities ethically by paying attention to our attitudes in the jungle during the activities. SUMECO, an organization dedicated to wildlife conservation, places a high value on eco-friendly principles.

The Exploration of Leuser’s Biodiversity Through Jungle Trekking in Bukit Lawang.

With its allure of unparalleled variety, Gunung Leuser National Park is referred to as the “lungs of the world.” This national park is one of the biggest flora and fauna protected areas in Southeast Asia, administratively including districts in Aceh and North Sumatra. The vegetation of the Gunung Leuser National Park (TNGL) region comprises Sumatra’s flora from the standpoint of biodiversity.

Flora of Gunung Leuser National Park.

The vegetation of Gunung Leuser National Park shares a strong relationship with that of the Malaysian Peninsula, Borneo, Java, and even the Philippines. Gunung Leuser National Park is home to 3,500 different varieties of plants. According to a quote from the official website of Gunung Leuser National Park, the bioclimate (an elevation climatic zone with a variety of floristic formations) is one of five factors used to define the natural vegetation formations. The connections between floristic composition and biogeography, hydrology, bedrock type, and soil make up the other four criteria.

Fauna of Gunung Leuser National Park.

Gunung Leuser National Park is known to be one of the ecosystem areas in the world with the most biodiversity. Sumatran Island belongs to the Malaysian subregion in terms of animal geography. The abundance of species in Gunung Leuser National Park is mostly concentrated in regions that are between zero and one thousand meters above sea level in elevation.

Gunung Leuser National Park and the surrounding area known as the Leuser Ecosystem Area are the habitats of the Sumatran elephant (Elephas maximus sumatranus), Sumatran tiger (Panthera tigris sumatrae), Sumatran rhinoceros (Dicerorhinus sumatrensis), Sumatran orangutan (Pongo abelii), siamang (Hylobates syndactylus), white handed gibbon (Hylobates lar), and Thomas langur / kedih (Presbytis thomasi).
