♪ Young orangutans have so much they need to learn from their mothers.

And, like humans, their childhood lasts a long time.

This mom is still learning herself.

She was only an infant when her mother was killed by loggers who cut down her forest home for its timber.

Now, it's all been converted into oil palm plantations.

♪ And this deforestation isn't just happening in Borneo.

All around the world, we are destroying our forests.

♪ Forests regulate our climate.

They create oxygen, absorb carbon dioxide, protect the soil, and are essential to the global water supply.

We need them to survive, as do the wild animals that make them their home.

♪ Now, some of us are learning to share the forests, and it's creating better lives for both animals and humans.

Singgong: [Speaking foreign language] Narrator: Dadai works for HUTAN, a local conservation group.

She's the head of the reforestation program in charge of restoring the orangutans' habitat.

It's an enormous task.

But as the village matriarch, she knows how to rally the local women.

[Speaking foreign language] Narrator: The original forest was made up of thousands of different plant species.

[Speaking foreign language] Narrator: To be successful, they must painstakingly replant as much of the forest's original diversity as possible.

[Speaking foreign language] [Engine starts] Narrator: Because almost every aspect of an orangutan's life is connected to trees.

They use trees for food.

♪ For shelter.

♪ For traveling through the forest.

♪ Orangutans are masters at using a variety of trees to get around their territory.

♪ The problem with plantations is they only have one tree species, oil palms, which are no good for orangutan traveling.

So orangutans can get isolated.

♪ This old male has survived the decimation of his original forest home.

♪ And in this new landscape of oil palms, he's trapped.

He needs a connecting forest corridor of native trees through the plantations.

♪ Dadai's team is trying to connect two isolated patches of protected forest.

A plantation is providing some of its land to be replanted with native trees.

[Speaking foreign language] Narrator: Today, the plantation manager has come to meet with Dadai.

[Speaking foreign language] Things grow so quickly here that only 3 years in, orangutans are already moving into some of these areas.

[Speaking foreign language] Narrator: And the plantations benefit as well.

They normally have a lifespan of only 50 years before the soil runs out of nutrients.

But new research shows how adding native trees to a plantation can replenish the soil and regulate temperature, extending the life of the oil palms.

[Speaking foreign language] Narrator: Over 15 years, Dadai's organization has planted and kept alive over 200,000 diverse native trees.

It's part of a bigger plan by the Malaysian government to add 100 million trees back into the region.

Lynx have something special.

Narrator: But the Iberian lynx are in trouble.

There are less than 2,000 left in the wild because their forest habitat is disappearing.

These forests, known as "dehesas," have been carefully created by humans over centuries.

The trees are used for cork production.

And underneath, the vegetation is grazed by livestock, creating open meadows filled with almost as much plant diversity as the Amazon jungle.

But for decades now, people have been moving off the land.

So these dehesas are not being maintained.

And invaders have moved in.

Rodríguez: Pine trees.

They are an invasive plant here.

Kill all around.

Narrator: Introduced over 100 years ago as a source of pine nuts, they've now spread everywhere and suck up so many nutrients nothing else can grow.

So there is less food for the rabbits, which the lynx need to survive.
