Project profile

Giant otters

Study species: Giant otter (Pteronura brasiliensis)

Project location: Peru’s Manu National Park and Madre de Dios river

Species fact: Giant otters are the largest otter species in the world. Adults can weigh up to 30 kilograms and reach a length of 6 feet.

Problem: Human activities, particularly small-scale gold mining, are causing the destruction of the aquatic habitats inhabited by giant otters and a decrease in the quantities of fish giant otters depend on.

Goal 1

Surveying protected and disturbed areas for otter presence and habitat destruction to examine the effects of gold mining on giant otter distribution and abundance.

Goal 2

Quantifying fish availability and mercury contamination to understand how human activities can affect giant otters.

Goal 3

Working with local communities to understand their perceptions towards giant otters and aquatic ecosystems and developing environmental education programs.

What your donation can achieve

£100
