Discovery Channel is unveiling three new series and a documentary that looks at subjects ranging from the work of conservationists to protect species on the brink of extinction to the way that the forces of nature impact life on Earth.

“We are going back to our roots to what our audiences crave — jaw-dropping, never-seen-before images of what makes our world so special,” said Nancy Daniels, chief brand officer at Discovery & Factual. “Discovery is at its best when unlocking secrets and potentially rewriting history.”

The programs will air in 2019 and 2020. The shows promise to highlight both exotic wildlife as well as exotic locations, from lush forests to arid deserts. One of the shows, “Wildlife Warriors,” will be executive produced by comedian and talk show host Ellen DeGeneres.

“More than 27,000 species are threatened with extinction. Some are well-known animals, some aren’t, but all are important to our ecosystem. It is an honor to be part of the team shedding light on the people who work to save our wildlife friends,” DeGeneres said in a statement.

The other projects include “Perfect Planet,” a five-part series that will look at the role that natural forces such as weather, ocean, currents, volcanoes and sunlight play in shaping our world. It will also look at how animals adapt to their environments.

“We all know that Planet Earth is a unique place,” said Alastair Fothergill, executive producer of “Perfect Planet,” in a statement. “It is the right size, orbiting the right distance from the right kind of star, it spins at the right speed, it tilts at just the right angle and it has a single, decent sized moon. By sheer luck, it is the only planet right now which has the perfect conditions for life.”

“Solving nature’s mysteries takes us on some amazing journeys. In this series, we don’t only go to some of the most spectacular places, we see those landscapes change over millions of years and we see how life is shaped by those great changes,” says Andrew Murray, “Mysterious Planet” series producer. “What I’m really excited about is how this gives us a whole fresh take on the Natural World!”

Discovery is also backing a series called “Serengeti,” a deep dive into African wildlife and the beautiful and brutal world they inhabit, as well as “Mysterious Planet,” an upcoming series that will look at various extraordinary locations in Indonesia, the Andes, the Caribbean, and Ethiopia.

“Of all the shows I have created or worked on, nothing compares to Serengeti,” said Simon Fuller, executive producer of “Serengeti” in a statement. “The heartfelt stories, the intensity of the drama and the depth of emotion is something I have been genuinely moved by. The genius of John Downer capturing the most personal and extraordinary moments from these beautiful animals’ lives is truly awe-inspiring. I am also proud to have Discovery and the BBC as the best possible partners for such an important television event.”

All of these special presentations will be part of new banner dubbed “Undiscovered,” a bit of branding that signifies that the stories will unfold on remote oceans and mountain ranges.
