Location
Mediterranean habitat in this region includes the area surrounding the Mediterranean Sea from Tel Aviv past Rome to Lisbon on the Atlantic Coast. The northern costs of Morroco, Algeria and Tunisia are included in this area as well.

Main threats
Deforestation, grazing, agricultural development, change in fire frequency and intensity.

Mediterranean Basin

Landscape and Terrain
The Mediterranean Basin represents the largest area of Mediterranean-climate in the world, and includes more than 20 nations distributed on both sides of the Mediterranean Sea. This region has complex topographic and climatic diversity. There are extensive woodlands dominated by both evergreen and deciduous species of oak and evergreen shrublands of diverse forms. Tall evergreen shrublands and woodlands occurring in relatively moist areas, often including pines, are termed maquis. Shrublands of lower height and rich in aromatic shrubs are termed garrigue. Finally, low arid and often spiny shrublands in the eastern Mediterranean Basin are termed phrygana in Greece and batha in Israel.

Human History
A long history of human impacts on the natural landscape over thousands of years has strongly affected the environments of this region and has accelerated over the past century. Many of our Western cooking herbs such as rosemary, thyme, tarragon, sage, and oregano are native to the Mediterranean Basin. Most of the modern grape varieties used for the production of fine wines and domestic olives come from the region.

Climate
Rainfall is highest in December and January. Average rainfall in these months is approximately 100mm. Average rainfall is as low as 10mm in the months of July and August. Temperatures reach an average monthly high of 30°C (86°F) in August and a low of below 5°C (41°F) in January.

Vegetation
Vegetation communities consist of extensive woodlands dominated by both evergreen and deciduous species of oak and evergreen shrublands, tall evergreen shrublands and woodlands (termed maquis,), shrublands of lower height and rich in aromatic shrubs (termed garrigue), and low arid and often spiny shrublands in the eastern Mediterranean Basin (termed phrygana in Greece and batha in Israel).
