How a Seed Mix Can Help Save Native Forests

In Brazil, seed collectors are helping restore vegetation and combat climate change while earning a living.

Muvuca, in Brazilian Portuguese, means a “chaotic mix.” In agriculture, it’s a method to restore the forest around headwaters of rivers and streams by planting a mix of seeds from dozens of native species, to copy the variety of nature.

It promotes the growth of native vegetation — expanding an area’s ability to capture carbon — and also prepares these new forests for climate change, because the mix includes seeds from areas that are already adapted to a hotter world.
