Biodiversity

Flora of the Sahara

• Adaptations of Desert Plants:
  • Water Conservation: Plants like cacti store water in their tissues.
  • Deep Root Systems: To access underground water sources.
  • Reduced Leaf Surface: Minimizes water loss (e.g., small or needle-like leaves).
• Notable Species:
  • Date Palm: Found in oases, vital for local agriculture.
  • Acacia Trees: Common in some regions, providing shade and wood.
  • Tamarisk: Salt-tolerant and often found near saline depressions.
  • Halophytes: Plants that thrive in salty environments, contributing to the unique desert ecosystem.

Fauna of the Sahara

• Survival Strategies of Animals:
  • Nocturnal Behavior: Many animals are active at night to avoid daytime heat.
  • Burrowing: Species like the fennec fox create burrows to escape the heat.
  • Water Conservation: Adaptations to minimize water loss, such as efficient kidneys in desert rodents.
• Key Species:
  • Mammals:
    • Fennec Fox: Smallest fox species with large ears to dissipate heat.
    • Addax Antelope: Critically endangered, adapted to arid conditions.
  • Reptiles:
    • Saharan Horned Viper: Venomous snake adapted to the desert.
    • Uromastyx Lizard: Herbivorous and well-adapted to the hot environment.
  • Birds:
    • Desert Sparrow: Commonly found in oases.
    • Egyptian Vulture: Scavenger that adapts well to desert life.
  • Insects:
    • Scarabs: Beetles that play a role in the desert ecosystem.
    • Desert Locust: Known for their swarming behavior, affecting agriculture.
