the search for lost species

All around the world, across habitats, across taxa and for all kinds of reasons, once-discovered species have fallen off our radar. These lost species are animals, plants, or fungi that have gone unseen for years or decades and are feared possibly extinct. Before we can save these species, we have to find them first.

In collaboration with more than 100 scientists, Re:wild has compiled a list of 2,100 species of animals and plants that are missing to science. Re:wild and our partners search some of the planet’s forgotten places and then work to protect species once found.

But this is about much more than the expeditions Re:wild is directly involved in. We’re calling on others to join the search and conduct their own expeditions for the lost species that have captured their hearts. Re:wild is working with teams and individuals the world over to publicize their stories of rediscovery and adventure as part of this shared campaign of hope and celebration. Read more in our FAQ.

Ecosystem Restoration

Supporting extensive native habitat restoration, such as reforestation, that assists in the recovery of ecosystems that have been degraded or destroyed, but that can rebound and rewild with a little help.

Protected Area Creation

Identifying and prioritizing wildlands in need of increased protection status, including establishing new protected and conserved areas, Indigenous-managed territories, and private protected areas in these places.

protected area management

Improving the way protected and conserved areas are managed—involving communities, Indigenous peoples, sociology, economics, business management, and wildlife crime prevention—to ensure a safer future for biodiversity and local communities.

rapid RESCUE

Working with the European Union to rapidly respond to emerging biodiversity threats that require immediate attention or relief in order to prevent catastrophic or irreversible damage to critical ecosystems and wildlife species, and the people who rely on them.
