Borneo is not just known for its lush greenery, but also for the rare and fascinating animals that call it home. From treetop dwellers to river swimmers, the Borneo fauna is truly one of a kind. In this ultimate guide, we’ll explore the concept of fauna, its role in the jungle ecosystem, and introduce you to 8 iconic Borneo animals you must know — especially if you’re visiting Malaysia.
What is Flora?
Before we dive into fauna, it’s important to understand flora. In simple terms, flora refers to all the plant life in a particular region or time period. This includes trees, shrubs, flowers, mosses, and ferns. In Borneo, flora is incredibly rich due to the tropical climate and unique biodiversity — making it a botanical paradise.

Differences Between Flora and Fauna
While flora refers to plant life, fauna refers to animal life. Think of it this way: flora provides the shelter and food, while fauna interacts with it to maintain the balance of nature. Both are essential elements of the Borneo rainforest ecosystem, and their symbiotic relationship is key to the survival of endangered species.

Importance of Flora in Jungle Ecosystem
The jungle ecosystem relies heavily on flora. Plants provide oxygen, prevent soil erosion, regulate temperature, and act as food and shelter for many species of fauna. Without healthy flora, Borneo fauna such as the orangutan or clouded leopard would struggle to survive. This mutual dependence is what makes conservation efforts so critical in Malaysian Borneo.
