Caatinga

Caatinga is a type of semi-arid tropical vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" comes from the Old Tupi word ka'atinga, meaning 'white forest' . The Caatinga is a xeric shrubland and thorn forest, which consists primarily of small, thorny trees that shed their leaves seasonally. Cacti, thick-stemmed plants, thorny brush, and arid-adapted grasses make up the ground layer. Most vegetation experiences a brief burst of activity during the three-month-long rainy season.
