Elephant population stabilises in Africa

The comprehensive analysis of African elephant populations reveals a positive trend in their southern heartlands, indicating stabilization following significant losses over the past century. This extensive study, which represents the most thorough examination of growth rates to date, also highlights the crucial role of connected protected areas in maintaining stable elephant populations.

The findings suggest that protected regions linked to other areas are more effective than isolated “fortress” parks in sustaining stable populations. Connectivity enables elephants to migrate between areas, mirroring natural behaviors observed in the past.

When core areas experience population growth, corridors into less protected buffer areas allow for dispersion. Conversely, if conditions deteriorate or poaching intensifies, elephants may migrate. However, challenges arise in buffer areas where more people reside, requiring careful planning to minimize conflicts, as elephants have the potential to harm individuals and damage crops.

In contrast, isolated parks, which strictly confine animals and exclude people, can lead to unsustainable population increases and, subsequently, mass deaths or culling. The research, covering 713 population surveys from 103 protected areas across Tanzania to southern regions, indicates an overall growth rate of 0.16% per year over the past 25 years, reflecting a conservation success in halting the decline of southern African elephant populations.

The study emphasizes the importance of connecting protected lands to ensure long-term stability. Professor Stuart Pimm of Duke University underscores the need to protect and connect elephant habitats, advocating for the restoration of a more cohesive natural landscape.

While the research offers encouraging news, it also highlights ongoing challenges, such as severe declines in some regions due to poaching, including south Tanzania, northern Zambia, and Zimbabwe. The mass death of elephants in Botswana in 2020 is attributed to the herd’s inability to migrate, emphasizing the significance of allowing natural movement for population stability.

The study’s scope covers southern Africa, and researchers emphasize the importance of landscape connectivity. Human activities, including roads, fences, agriculture, and mining, can disrupt connectivity, necessitating thoughtful planning to address local factors and minimize conflicts between humans and elephants. Care for the well-being of local communities is deemed essential, recognizing that the successful conservation of elephants is intricately linked to the harmony between people and wildlife in the landscape.

The study concludes that while southern savannah elephant populations have stabilized, continued conservation efforts and improved connectivity are crucial for the species’ long-term well-being.
