Caatinga, WWF ecoregion in northeastern Brazil
Caatinga is an ecoregion in northeastern Brazil where thorn trees, cacti, and shrubs grow across dry plains and low hills. The plants shed leaves during drought, turning the landscape gray until rains return.
Human groups have lived here for thousands of years, leaving stone tools and rock art in caves. Adapting to the dry climate shaped how these early inhabitants survived over time.
The name Caatinga comes from Tupi language, meaning white forest, reflecting the traditional knowledge of native communities who inhabited this semi-arid environment.
The region is best visited during the rainy season when plants turn green and the landscape changes. Water and sun protection are essential during dry months, as shade is scarce.
Many plants here grow only in this dry zone and nowhere else on Earth. Some cactus species store water in thick stems and bloom after the first rains.
