Caatinga

The Caatinga is a xeric shrubland and thorn forest ecoregion in northeastern Brazil. The name "Caatinga" comes from the Tupi language and means "white forest," referring to the thorny trees that often lose their leaves during the dry season, leaving behind a silvery-white appearance. This region is characterized by a semi-arid climate with high temperatures and irregular rainfall, leading to a unique and highly adapted flora and fauna.

The vegetation in the Caatinga is predominantly composed of drought-resistant plants, including cacti, thorny shrubs, and small trees. Many species have developed adaptations such as deep root systems, water-storing tissues, and small leaves to survive the prolonged dry periods. Despite its arid conditions, the Caatinga is a biodiversity hotspot, hosting a significant number of endemic species. Common animals include various reptiles, birds like the Lear's macaw, and mammals such as the maned wolf.

Human activity in the Caatinga primarily involves agriculture, cattle ranching, and the collection of firewood. These activities, along with periods of drought, have led to significant environmental degradation and desertification in some areas. Conservation efforts are underway to protect the remaining natural habitats and promote sustainable land management practices in the Caatinga. The ecoregion plays a crucial role in the regional climate and water cycle, making its preservation important for both ecological and socio-economic reasons.
