The maquis, or macchia, is a type of dense, evergreen shrubland found primarily in the Mediterranean region. This vegetation is characterized by hardy shrubs and small trees such as holm oak, rosemary, and juniper, which thrive in the hot, dry summers and mild, wet winters typical of Mediterranean climates. The maquis habitat is well adapted to fire, with many plants having thick bark and deep root systems to survive and regenerate after wildfires. It provides a unique and rich ecosystem for a variety of wildlife.
