Why black spider monkeys matter

The black spider monkey is an essential part of the tropical rainforest ecosystem. They play a key role in seed dispersal, allowing their forest environment to continue to grow and thrive.

Threats to black spider monkeys

The destruction of tropical rainforests and threats from hunting pose the greatest challenge to the black spider monkey’s survival. Because they prefer mature tropical forests and seldom venture into disturbed habitats, these monkeys are especially vulnerable to the effects of forest fragmentation.

How WWF is taking action to protect black spider monkeys

To combat the destruction of the black spider monkey’s habitat, WWF works to protect the forests they need to survive. We support the creation and management of protected areas and promote responsible forest management, including Forest Stewardship Council (FSC) certification, outside of protected areas.
