Environment

The Ahaggar Mountain range is chiefly volcanic rock and contains a hot summer climate, with a cold winter climate (temperatures fall below 0°C in the winter). The mountains are young--about 2 million years old. Rainfall is rare and sporadic. However, since the climate is less extreme than in most other areas of the Sahara, the Ahaggar Mountains are a major location for biodiversity

Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire planet. Biodiversity is one measure of the health of ecosystems. Life on Earth today consists of many millions of distinct biological species. The United Nations declared the year 2010 as the...

 remained viable into the 20th century, but is now thought to be extirpated within this entire region.

Some natives still report attacks by unidentified canines, possibly lycaon. Camera trapping should confirm whether or not this most elusive of African canines continues to exist in or near the mountain range. A group of field researchers including Koen de Smet and Farid Belbachir have collected information about reported lycaon sightings in Ahaggar and Tassili. Next round of camera trapping is planned for summer 2010, when genetic analysis of recovered carnivore scats will also be undertaken.

 Canid Specialist Group lists the African Wild Dog as most likely extirpated in this area, but also reports that the precise distibution of all populations is unknown and states that further research, including field surveys, are required. This applies to a number of regions on the African continent, including environs of the Ahaggar Mountains of Algeria.
