Endangered species and wilderness are in rapid decline and saving them has become an urgency for human kind in which ESI is playing a unique critical and concrete role. Pierre Fidenci, Founding Director of Endangered Species International (ESI).

Be the hero nature needs! Join us to save endangered species and protect wild habitats including rainforest and coral reefs. Saving nature across generations is at the very heart of what we do.

ESI is devoted to protecting biodiversity and endangered species in different arenas through creation of effective protected areas; strong community involvement; restoration of wilderness; science and wildlife monitoring; law enforcement; creative awareness and education; and negotiation with government and industry. We spend considerable time in the field where our work shows clear advancements for protecting nature.

In 2015, ESI protected and saved 287 threatened species including aquatic and terrestrial plant and animal species. Examples include rare Acropora coral, giant clam (Tridacna gigas), western lowland gorilla (Gorilla gorilla), African forest elephant (Loxodonta cyclotis), Philippine tarsier (Carlito syrichta), dugon (Dugong dugon), green sea turtle (Chelonia mydas), Gigante island frog (Platymantis insulates), and Kamagong tree (Diospyros blancoi).

In 2015, we restored and protected vital habitats and ecosystems including rainforests, mangrove forests, wetlands, coral reefs, and seagrass beds. Examples include planting and monitoring 16,000 mangrove trees covering twelve species, planting more than 100,000 native trees, and coral gardening at nine key ESI marine sites restoring corals and fish populations. ESI planted thousands of trees in tropical regions to help restore many rainforests. In cooperation with local communities, we brought back endangered native tropical trees at various locations to encourage not only reforestation, but an increase in overall biodiversity. Post-monitoring studies showed a seventy percent survival rate for all trees planted during that year. Our activities are made to last and everyone can see a difference on the ground.

Only ten percent of all large fish (e.g., tuna, swordfish, marlin, cod, halibut, skates and flounder) remain in the sea. If present fishing levels persist, these great fish will go the way of the dinosaurs. During 2015, ESI backed the reduction of large fish fishing and aided small local fisherman who fish sustainably and support marine protected areas.


Saving nature is at the very heart of what we do at every level. No wasting resources 98% of ESI's spending is directed to field conservation activities. Make your year-end donation today and support our best efforts to protect nature!
