Balanites aegyptiaca
The varied landforms in the commune consist of plateaus, valleys and their catchments. The average annual rainfall in the municipality was 458.84 millimeters in the period between 1997 and 2006 with an average of 41 rainy days in the year. The rainy season typically lasts from June to September. The once rich wildlife Garhangas has increasingly declined since the 1950s. In the plateaus occasionally grow acacia, "Ziziphus mauritiana", "Piliostigma reticulatum" and "Balanites aegyptiaca". In the valleys there is dense vegetation. The wild animal population - monkeys, squirrels, rabbits, and guinea fowl - is hurt by a lack of habitat, water shortages and increasing human settlement in the area.
