African Forest Elephant Loxodonta cyclotis

African Forest Elephant Loxodonta cyclotis

Location: Central and West Africa – Guineo-Congolian tropical forests, including Cameroon, Gabon, Republic of Congo, Democratic Republic of Congo, and surrounding regions.

IUCN Status: Critically Endangered

The African Forest #Elephant is a Critically Endangered species found in the dense #rainforests of Central and #WestAfrica. They are smaller than their savanna relatives, with straighter tusks and rounder ears, uniquely adapted to their forested habitat. As ecosystem engineers, these elephants play a crucial role in maintaining Afrotropical forests by dispersing seeds and mitigating against climate change by shaping forest composition. However, relentless #poaching for ivory, habitat destruction due to #palmoil, #cocoa and #tobacco agriculture, and human-elephant conflict have decimated their population. Recent studies have shown that African Forest Elephants’ movement patterns vary significantly between individuals, with some elephants exploring vast distances while others remain in small home ranges. This variation poses unique challenges for conservation efforts. Resist and fight for their survival each time you shop, be #vegan and #BoycottPalmOil #Boycott4Wildlife.

Rapid land use change, including palm oil plantations across their range is driving the direct loss and fragmentation of habitat, is an increasing threat to African elephants across their range.

Appearance and Behaviour

African Forest Elephants are smaller than their savanna counterparts, with a shoulder height of 2 to 3 metres. They have a more compact build, rounded ears, and long, narrow tusks that point downward, (Gobush et al., 2021). Their grey skin is often darker due to the humid rainforest environment. They live in small, matriarchal family groups and display remarkable individual variation in movement behaviours. Some elephants, known as “explorers,” travel vast distances, while others, the “idlers,” remain within confined home ranges. These behavioural differences complicate conservation efforts, as strategies must account for their diverse space-use needs.

These elephants are highly intelligent and social, living in small, matriarchal family groups that navigate the rainforest together. Their deep infrasonic rumbles travel through the ground, allowing communication over vast distances, even in the thickest jungle. Recent research has revealed that their vocalisations have a structure akin to human syntax—complex combinations of calls used to convey intricate meanings (Hedwig & Kohlberg, 2024).

Other research has found that the foraging, seed dispersal and exploration of African Forest Elephants helps to mitigate African forests against climate change. A 2019 study from the Ndoki Forest in the Republic of Congo (ROC) and LuiKotale in the Democratic Republic of Congo (DRC) estimated that if elephants were removed from these sites, the loss of their forest-shaping food preferences would reduce the forest’s carbon capture by 7%.

Diet

Forest Elephants are frugivorous and play an irreplaceable role as seed dispersers, particularly for large fruiting trees. They are responsible for spreading the seeds of over 41 timber species, including Bobgunnia fistuloides (pao rosa), a tree prized for its high-value wood (Blake et al., 2009; Campos-Arceiz & Blake, 2011). Without these elephants, the rainforest’s ability to regenerate and store carbon would be drastically diminished.

Reproduction and Mating

With a gestation period of 22 months—the longest of any land mammal—female African Forest elephants give birth only once every four to six years (Gobush et al., 2021). Due to their slow reproductive rate, population recovery is incredibly difficult, making conservation efforts even more urgent. Calves remain under their mother’s care for over a decade, learning crucial survival skills in the rainforest.

Geographic Range

African Forest Elephants roam vast home ranges, some spanning over 2,000 km² (Beirne et al., 2021). Their movements are largely dictated by fruiting cycles, water availability, and human encroachment. A recent study found that they exhibit remarkable individual variation in movement patterns—some acting as ‘explorers,’ roaming far and wide, while others remain within familiar territories (Beirne et al., 2021). Roads and logging concessions disrupt these traditional routes, forcing elephants into human settlements and escalating conflict.

Threats

• Illegal Wildlife Trade and Poaching: The illegal and criminal trade in elephant ivory continues to drive rampant poaching. Despite international bans, demand remains high in black markets (Wittemyer et al., 2014; Maisels et al., 2013).
• Palm Oil Agriculture Expansion: Forests are being obliterated for palm oil, cocoa, tobacco and rubber plantations, erasing habitat at an alarming rate (Scalbert et al., 2022).
• Logging, Mining, and Infrastructure Expansion: The development of roads and infrastructure for timber and mining grants poachers greater access to once-inaccessible forest areas (Beirne et al., 2021).
• Human-Elephant Conflict: Shrinking forests push elephants into farmland, leading to fatal clashes with farmers trying to protect their crops (Ngama et al., 2016).
• Climate Change: Disruptions in rainfall patterns and fruiting cycles impact the food supply of African Forest Elephants, forcing them into riskier migration routes where they can come into contact with poachers or conflict with farmers.
• Slow Reproduction Rate: African Forest Elephants have a long gestation periods and high calf mortality, their populations cannot recover quickly from losses.

Elephants and Language: Call Combinations and Syntax

Groundbreaking research has revealed that African Forest Elephants use complex call combinations, akin to human syntax, to communicate in high-stakes situations (Hedwig & Kohlberg, 2024). Their vocal repertoire includes:

• Low-frequency rumbles: Used to coordinate movements and social interactions. These deep sounds can travel several kilometres through dense rainforest.
• Broadband roars: Express distress, urgency, or aggression, particularly in response to predators or conflict.
• Combined calls: When rumbles and roars are merged, they create new meanings. These combinations are more frequently used in competitive situations, suggesting that elephants alter their vocal signals to convey specific messages in dangerous or high-emotion contexts.

The ability to combine calls strategically may help elephants navigate social disputes, secure access to resources, or reunite with separated family members. This discovery sheds light on the cognitive abilities of these animals and their sophisticated social lives.

African Forest Elephants and Timber Concessions

Timber and palm oil concessions now cover vast portions of forest elephant habitat, with little understanding of how these logging operations impact elephant populations (Scalbert et al., 2022). While elephants can persist in selectively logged forests, they require large, undisturbed areas to sustain viable populations. Key findings include:

• African Forest Elephants regenerate forests: By dispersing seeds of high-carbon tree species, they facilitate the regrowth of timber species, making their role essential for maintaining the economic value of these forests.
• Logging alters movement patterns: While some elephants adapt to fragmented landscapes, others are displaced, forced into human-dominated areas where they are at greater risk of poaching and conflict.
• Forest loss drives ecological collapse: Without elephants maintaining seed dispersal, many commercially valuable trees may struggle to regenerate, ultimately degrading the timber industry’s long-term viability.
