In News:

• The population of African elephants has been declining rapidly, with data showing alarming drops across the African continent.
• Survey Period: The study covers population data from 475 sites in 37 countries over 52 years (1964-2016).
• Population Decrease:
  • Savannah Elephants: A 70% decline on average across surveyed sites.
  • Forest Elephants: A 90% decline on average across surveyed sites.
• Overall Impact: The study indicates a 77% average decline in elephant populations across both species.

Main Drivers of Decline

• Poaching: Illegal hunting for ivory and other body parts remains a major threat.
• Habitat Loss: Urbanization, agricultural expansion, and climate change are encroaching on the elephant’s natural habitats.
• Human-Elephant Conflict: Increased human settlements near elephant habitats lead to conflicts, further endangering elephant populations.

Species Overview

• Two Subspecies:
  • Savannah Elephant (Loxodonta africana): Larger and more common, found in open savannas.
  • Forest Elephant (Loxodonta cyclotis): Smaller and more elusive, found in dense rainforests.
• Conservation Status:
  • Savannah Elephant: Endangered (IUCN).
  • Forest Elephant: Critically Endangered (IUCN).
• CITES Listing: Both species are listed under CITES Appendix I, which bans international trade in endangered species.

Regional Impact

• Northern and Eastern Africa: These regions have seen drastic declines, particularly in the Sahel (Mali, Chad, Nigeria), where elephants have been extirpated (locally extinct) due to poaching and insufficient protection.
• Southern Africa: Positive Growth in some areas, particularly in Botswana, Zimbabwe, and Namibia, where elephant populations are growing due to strong conservation efforts.

Conservation Success

• Southern Africa: 42% of the surveyed sites showed increasing elephant populations, a testament to successful conservation strategies.
• Government and NGO Efforts: Successful population growth is often attributed to active management, including anti-poaching laws, protected areas, and conservation funding.

Elephant Behavior and Reproduction

• Social Structure: Elephants live in family units led by mature females, with strong social bonds.
• Low Sleep Time: Elephants sleep only 2 hours per day on average.
• Reproduction: They have a long gestation period of up to 2 years, and calves are cared for by mothers and allomothers (non-mother females).

Conservation Challenges

• Sustainability: Continued poaching and habitat destruction threaten to undo gains made in conservation.
• Fragmentation of Populations: With many elephants in isolated pockets, genetic diversity is declining, which could lead to long-term problems for species survival.
