Re:wild x Colossal

Where conservation and cutting-edge technology combine

A partnership for a wilder world

When Re:wild and the Colossal Foundation, the nonprofit arm of Colossal Biosciences, began talking about a possible partnership in 2022, one thing became abundantly clear: by fusing Colossal’s de-extinction toolkit and Re:wild’s expertise, we could revolutionize the conservation of Critically Endangered species on the brink of extinction, and bolster the health of the planet in a new and unprecedented way.

We are using cutting-edge technology to protect and restore the most ancient technology that keeps our planet going: the wild.

Where conservation and cutting-edge technology combine

Colossal is developing de-extinction technology to bring back the iconic Thylacine, Dodo and Woolly Mammoth from extinction as re-built de-extinct species. Together we will focus on Critically Endangered species by deploying this technology to revolutionize how we prevent these species from going Extinct and restore their populations.

Today we're working together, and with local partners, to protect and restore:

In the future we’re hoping to work together to protect and restore:

Vaquita

Saola

Red Wolf

Northern Quoll

We cannot help restore species and protect their habitats unless we know where they are – and that they still exist.

Re:wild’s flagship, Guinness World Record-setting program, the Search for Lost Species, is all about looking for plants, animals and fungi that have been lost to science for at least 10 years — sometimes hundreds of years.

With the help of IUCN Species Survival Commission specialist groups, Re:wild has pulled together a list of more than 4,300 lost species across 160 countries. Colossal has joined the search by supporting our most wanted lost species subset, which span species groups, geography and habitat.

So far 12 of the world’s most wanted lost species have been rediscovered since the Search for Lost Species launched in 2017.

Together we are...

Supported by the Colossal Foundation, together we have developed a 10-year conservation strategy to benefit countless species and restore critical ecosystems, combining Re:wild’s expertise in wildlife and ecosystem conservation along with partner and community engagement, with Colossal’s advances in the fields of genomics, assisted reproductive technologies, gene editing and computational biology.

Re:wild will advise Colossal on the ecological feasibility of introducing re-built de-extinct species to their native ecosystems, while governments and other experts will advise on the legal, social and ethical feasibility. All of this work will be done in close collaboration with local communities, governments, organizations and Indigenous peoples.

  • Advancing Conservation Breeding

    Supporting or creating conservation breeding programs with local partners to utilize Colossal’s de-extinction technologies to help Endangered and Critically Endangered species, and support their reintroduction into the wild.

  • Reintroducing Threatened Species

    Supporting local partners to reintroduce more than 30 threatened species back to their native ecosystems as part of a new species reintroduction fund.

  • Searching For Lost Species

    Supporting local conservationists in the search for at least 50 lost species — species that have not been documented in 10 or more years, but could still exist. Colossal is a key supporter of Re:wild’s Search for Lost Species program..

  • Restoring Vital Ecosystems

    Working with local partners and governments to restore at least three key sites.

Frequently Asked Questions:

How did Colossal and Re:wild connect?
As a Texas-based company and a Texas-based organization, Colossal and Re:wild connected two years ago and have been talking about the potential for this partnership since then, before the company even officially launched! During our first discussion, we were immediately struck by how our missions were not only similar, but complementary, giving us an unprecedented opportunity to together save species that are on the brink of extinction.
Do we need this technology to stop biodiversity loss?
We know that efforts to protect and restore biodiversity and ecosystems are effective. But there are too few resources and not enough political will to scale those efforts quickly enough to prevent the extinction of threatened species. And with more than 1 million species at risk of extinction by 2050, we need every tool available not only to stop extinction, but to actively restore species and ecosystems. This technology is allowing us to accelerate those efforts in an unprecedented way.
How long will this all take? When will we start seeing the impacts of this technology on the planet?
It will depend on the species, the technology, the habitat, the threats we need to mitigate, and the process of working with local communities and governments. Restoring a nearly extinct species back to a healthy, sustainable population is hard work and requires time. It took 50 years between the first idea to reintroduce Gray Wolves back to Yellowstone and their actual reintroduction. Although Colossal’s technology will accelerate conservation efforts, reintroduction processes require sound science, deep community engagement, and strong political will. We strive to follow the highest standards throughout the implementation of these projects.
Bringing back species from extinction seems audacious! Is this really possible?
It sounds audacious because it is audacious…and that is exactly what our planet needs! With more than 1 million species at risk of extinction by 2050, we need every tool available to help. And with Re:wild’s expertise in species and ecosystem restoration and protection, and Colossal’s innovative de-extinction technology already in the works, we are confident that we will be able to accelerate the restoration of species on the brink of extinction.
How do you select which species on the brink to work on together?
We will work alongside local partners and governments to help efforts to recover and restore the Asian Elephant, African Forest Elephant, African Savanna Elephant, Northern White Rhino, Sumatran Rhino, Pink Pigeon, Victorian Grassland Earless Dragon and Tasmanian Devil, as well as the ecosystems where they live.

Colossal has already engaged local partners and is helping conservation breeding efforts for the Northern White Rhino, Asian Elephant, African Forest Elephant, African Savanna Elephant and the Victorian Grassland Earless Dragon.

Since its founding, many of Re:wild’s conservation efforts have focused on threatened and little-known species, as well as restoring sites in Asia, Africa, Oceania, the Caribbean, and South America.

In 2020, Re:wild, Aussie Ark and WildArk, reintroduced Tasmanian Devils to mainland Australia. It was the first time the species was back on the mainland since 3,000 years ago. Re:wild also supports efforts to protect and restore Endangered species in Australia, such as the Eastern Quoll, and the Manning River Turtle.

In Africa, Re:wild works with partners that are protecting critical habitats for elephants and rhinos from Virunga National Park, to the Okavango River Basin, to the Zambezi River Valley.

Re:wild supports efforts led by the government of Indonesia to protect Sumatran Rhinos and move individuals living in isolation from each other to conservation breeding centers.

As the partnership progresses, we expect the number of species on the brink we will work to rewild will grow.
How are you funding all of this work?
Support for this partnership comes from the Colossal Foundation, a 501(c)(3) dedicated to supporting the use of cutting-edge technologies to conservation efforts globally to help prevent extinction of keystone species. One core principle of the partnership is that we are trying to bring new resources to conservation and not compete with others for existing, but scarce, conservation support.
When all is said and done, how will you define success for this partnership?
We will together define success when we have not only prevented the extinction of species on the brink, but restored them to sustainable populations that are actively supporting the health of their ecosystems and, therefore, the health of our planet.
What does it mean for Re:wild to be Colossal’s strategic conservation partner? Is Colossal partnering with any other conservation groups?
As Colossal’s strategic conservation partner, Re:wild will work with and guide Colossal on the company’s work related to rewilding, protecting and recovering threatened species, and working with global and local partners. In addition, Colossal has been working closely with local conservation partners since it was founded, including Save the Elephants, Aussie Ark and Elephant Havens.
