Suri, spending the day foraging in a fruiting ficus tree!
Ficus trees are critically important for orangutans in Sumatra, both ecologically and nutritionally.
🌳 Important Food Source
Did you know ficus trees fruit year-round? Unlike many tropical trees that fruit seasonally, ficus trees produce fruit continuously or at different times, making them a reliable food source when other fruits are scarce.
Ficus availability can affect orangutan reproductive success, health, and ability to raise young.
🌍 Keystone Ecological Role
Ficus trees are considered keystone species in tropical forests, meaning they support a wide range of wildlife.
Besides orangutans, birds, bats, monkeys, and insects also feed on their fruits. This makes ficus trees crucial for maintaining biodiversity in Sumatran rainforests.
🪹 Habitat & Nesting
Orangutans build nests in the canopy to sleep in each night. Ficus trees, with their broad canopies and sturdy branches, often provide ideal nesting sites.
Ficus trees are a lifeline for orangutans in Sumatra, providing critical food, nesting, and ecological support.
We are lucky to have many ficus trees in the area where we monitor orangutans and our team is working hard to ensure they are protected as they are vital to the long-term survival of the orangutans in the area.
