Protecting Species


Endangered Species Day will be celebrated on May 19, 2023, and this year marks the 50th anniversary. WWF highlights the many endangered and critically endangered wildlife on this day and every day, working to build awareness and partnerships with local communities, governments, businesses, and the rest of the world to take action to protect them.

Indian tiger

From elephants to polar bears, WWF fights to secure a future for animals on the planet we all share. WWF helped bring back the Amur tiger and Africa’s black rhinos from the edge of extinction. We are giving isolated, dwindling populations of black-footed ferrets and river dolphins a second chance.

WWF continues to keep habitats and landscapes thriving. We envision, create, test, and deliver solutions for a crowded planet. We work with partners at all levels, from community leaders to governments and multinational bodies. But our work is far from done, and WWF constantly strives to protect the species we all care about.

How wildlife help combat the climate crisis

Combatting climate change helps save wildlife populations around the globe, but the reverse is also true: Wildlife conservation plays an essential role in regulating our climate. By saving wildlife, we help save the planet, including ourselves.

What WWF Is Doing


Rhinos were once widespread across Africa's savannas and Asia's tropical forests. But today very few rhinos survive outside national parks and reserves. Successful conservation efforts have helped subspecies like the greater one-horned (or Indian) rhino, to increase in number. In Africa, black rhinos have doubled in number over the past two decades, but total numbers are still a fraction of the estimated 100,000 that existed in the early part of the 20th century. Increasingly, rhinos are killed by poachers for their horns. WWF works to help governments and authorities crack down on wildlife crime. We set up training for law enforcement, track rhino movements via transmitters and set up hotlines—all to help stop poachers and build a future in which the rhino can thrive.


After a century of decline, tiger numbers are on the rise. At least 4,500 tigers remain in the wild, but much more work is needed to protect this species that is still vulnerable to extinction. Tigers may be one of the most revered animals, but they are also vulnerable to extinction. WWF believes we can save wild tigers. 

Polar Bears

Polar bear

Polar bears spend the majority of most of their lives on frozen Arctic sea ice. The loss of sea ice habitat due to climate change is now the greatest threat to their survival. WWF aims to sustainably preserve the rich biodiversity of polar bear habitats. We work with partners and local communities to establish a management plan for the “Last Ice Area” in Canada and Greenland—a region scientists believe will be preserved as sea ice longer than anywhere else. The plan conserves habitat for all Arctic ice dependent species and protects the cultural heritage and economic needs of local people.


Orangutans have experienced sharp population declines. A century ago there was likely more than 230,000 orangutans in the wild. Today, the Bornean orangutan is estimated to number about 41,000 and the Sumatran about 7,500, and their habitats are fast disappearing. WWF has worked on orangutan conservation since the 1970s. Our efforts include conserving orangutan habitat, stopping poachers, promoting sustainable forestry and agriculture, and halting the orangutan pet trade.

Marine Turtles

Loggerhead Turtle

Nearly all species of marine turtle are classified as endangered. Human activities—hunting, poaching, habitat destruction and accidental capture in fishing gear—have tipped the scales against the survival of these ancient mariners. WWF is committed to stop the decline of marine turtles and work for the recovery of the species. Our work to secure a future for this species includes eliminating marine turtle bycatch from fisheries, reducing the unsustainable harvest and illegal trade in marine turtles, and stemming the loss of critical marine turtle habitats.
