Southern giraffe

The Southern giraffe (Giraffa giraffa) is one of four recognized species of giraffe, distinguished by its tall, slender build and unique coat pattern featuring large, irregularly shaped brown patches outlined by lighter tan areas, with speckled lower legs.^[1]^[2] This species is native to southern Africa, where it inhabits diverse landscapes including savannas, grasslands, and open woodlands, primarily in countries such as Namibia, Botswana, South Africa, Zimbabwe, and Zambia.^[2] It comprises two subspecies: the Angolan giraffe (G. g. angolensis), found mainly in arid and semi-arid regions of Namibia and northern Botswana, and the South African giraffe (G. g. giraffa), distributed more widely across southeastern Africa.^[2] As the tallest living terrestrial animal, the Southern giraffe reaches total heights of 4.3 to 5.8 meters (14 to 19 feet), with males typically taller and heavier than females, weighing up to 1,270 kilograms (2,800 pounds).^[3] Its elongated neck, supported by a specialized cardiovascular system, allows it to browse foliage from tall acacia trees, while its prehensile tongue—up to 45 centimeters (18 inches) long—enables precise feeding on thorny vegetation.^[4] Southern giraffes are herbivores, primarily consuming leaves, twigs, fruits, and flowers from woody plants like Acacia and Commiphora species, with their diet varying seasonally and regionally to exploit available resources.^[3] They exhibit social behavior, often forming loose herds of 10 to 20 individuals, though males are more solitary and engage in "necking" displays to establish dominance during mating.^[4] The Southern giraffe is the most abundant giraffe species, with an estimated wild population of approximately 68,837 individuals as of 2025, showing a positive trend, having more than doubled over the past three decades due to conservation efforts.^[2] The Angolan subspecies numbers around 15,660, having tripled since the 1980s, while the South African subspecies exceeds 53,000.^[2] Although the overall giraffe lineage faces threats like habitat loss and poaching, the Southern giraffe is classified as Least Concern by the IUCN for its Angolan subspecies, with the South African likely to follow suit pending formal evaluation.^[2] This reclassification into distinct species in 2025 underscores the need for targeted conservation to maintain genetic diversity and prevent hybridization from human-mediated translocations.^[1]

Taxonomy

Etymology

The genus name Giraffa derives from the Arabic term zarāfah, meaning "one who walks swiftly," reflecting the animal's characteristic gait.^[5] The species epithet giraffa is a variant of the genus name, forming a tautonym that emphasizes the animal's distinct identity within the genus.^[6] The common name "Southern giraffe" designates Giraffa giraffa based on its distribution across southern Africa, including countries such as Namibia, Botswana, Zimbabwe, and South Africa, thereby distinguishing it from other giraffe species like the Northern, Masai, and Reticulated giraffes.^[1] Historically, Carl Linnaeus named the giraffe Giraffa camelopardalis in 1758, combining "camel" for its body shape and "pardalis" (leopard) for its spotted coat, as observed in early European descriptions.^[7] In 2016, genetic analyses proposed elevating the southern population to full species status as Giraffa giraffa, supported by evidence of distinct lineages.^[7] This revision received official recognition from the International Union for Conservation of Nature (IUCN) in 2025, aligning taxonomy with genomic data for enhanced conservation.^[1]

Phylogenetic history

The phylogenetic history of the Southern giraffe (Giraffa giraffa) originates in the Miocene epoch, when the Giraffidae family emerged as ruminants adapted to browsing lifestyles, with the genus Giraffa diverging from the okapi (Okapia johnstoni) lineage approximately 11.5 million years ago. This split reflects broader pecoran ruminant diversification, during which early giraffids developed elongated necks and ossicones for accessing high foliage in expanding savanna ecosystems across Eurasia and Africa. Fossil evidence from this period, including primitive forms like Prodremotherium and Climacoceras, illustrates the gradual evolution of these traits from deer-like ancestors.^[8] Key insights into the more recent phylogeny come from a 2016 multi-locus study analyzing mitochondrial and nuclear DNA from 190 giraffes, which revealed that the Southern giraffe lineage diverged from other giraffe clusters about 1.25–2 million years ago during the Pleistocene.^[9] This divergence likely occurred amid climatic shifts that fragmented habitats in eastern and southern Africa, promoting genetic isolation. The fossil record supports this timeline, with early giraffids such as Samotherium—a medium-sized, short-necked form—documented in Pliocene African sites like Laetoli in Tanzania, representing transitional morphologies between Miocene ancestors and modern Giraffa. The 2025 IUCN taxonomic assessment solidified the species status of the Southern giraffe as one of four distinct giraffe species, based on integrated evidence from skull morphology (e.g., discriminant analyses of 515 specimens showing unique rostrum and ossicone features), coat pattern variations, and genome-wide nuclear DNA analyses indicating minimal gene flow with other lineages.^[10] These findings, drawing on studies like Coimbra et al. (2021), estimate the Southern giraffe's intraspecific lineages diverged 230–370 thousand years ago, underscoring its evolutionary distinctiveness despite historical admixture events.^[11] More recent phylogenomic analyses revise the inter-lineage divergences among giraffe species to approximately 230–370 thousand years ago.^[11]

Subspecies

The Southern giraffe (Giraffa giraffa) is classified into two subspecies: the Angolan giraffe (G. g. angolensis) and the South African giraffe (G. g. giraffa), distinguished primarily by genetic markers and subtle morphological differences in coat patterns.^[10]^[12] These subspecies were originally considered part of a single southern population but were formally separated in 2016 following multi-locus genetic analyses that revealed distinct evolutionary lineages diverging approximately 230–370 thousand years ago, with limited gene flow between them.^[10]^[11] In 2025, the IUCN Species Survival Commission's Giraffe and Okapi Specialist Group endorsed this taxonomy, confirming the subspecies' validity based on whole-genome sequencing of over 80 individuals, while noting minor admixture in contact zones but no significant hybridization threats to their genetic integrity in wild populations.^[10]^[13] The Angolan giraffe (G. g. angolensis) is characterized by large, angular brown blotches with pale edges that do not extend fully down the legs, which are typically plain-colored without spotting.^[12] Its current population is estimated at approximately 15,660 individuals (range: 11,879–19,923), reflecting recovery from historical declines.^[14] Historically widespread across southwestern Africa, this subspecies was extirpated from much of Angola due to civil conflict and poaching but has been reintroduced to sites like Iona National Park in Angola from Namibian stock between 2023 and 2024, aiding range expansion into Botswana and Namibia.^[14]^[10] The South African giraffe (G. g. giraffa) features darker, star-shaped patches in various shades of brown, surrounded by light tan areas, with spotting that extends irregularly down the legs.^[12] This subspecies has a population of around 53,000 individuals (range: 40,094–70,390), the largest among giraffe subspecies, and exhibits a slightly more robust build suited to mesic savanna habitats compared to the leaner form of its northern congener.^[14]^[10] It occurs across southern Africa, including South Africa, Zimbabwe, Mozambique, and Zambia, with reintroduction programs in Eswatini, Malawi, and Mozambique enhancing connectivity in fragmented ranges.^[14] Distributional overlaps with the Angolan giraffe occur in northern Botswana and northwestern Namibia, where low-level genetic mixing has been documented but does not compromise subspecies distinctiveness.^[10]^[13]

Physical characteristics

Size and build

The Southern giraffe (Giraffa giraffa) displays significant sexual dimorphism in its size and build, with males substantially larger than females to support roles in combat and foraging. Adult males typically attain a total height of 5.2–5.7 m, with shoulder heights around 3.3 m, while females reach 4.0–4.7 m in total height and approximately 2.8 m at the shoulder.^[4]^[15] Males weigh 900–1,200 kg on average, compared to 600–900 kg for females, contributing to their robust frame adapted for dominance displays.^[4] This dimorphism extends to the neck, which can measure up to 2.4 m in length and consists of just seven elongated cervical vertebrae, enabling access to elevated vegetation without additional skeletal segments.^[15] The giraffe's long, slender legs, which are nearly equal in length to the front and hind pairs, facilitate a distinctive gait and allow for stride lengths of up to 5 m during movement across savannas.^[16] Ossicones—horn-like protuberances formed from ossified cartilage covered in skin and hair—are more prominent and thicker in males, often reaching 13.5 cm and becoming hairless with age due to use in necking combats, whereas females retain tufted tips.^[15] Males also develop thicker skin on the neck and chest as an adaptation for withstanding impacts during these fights.^[15] Physiological adaptations underscore the Southern giraffe's unique build, particularly in feeding and circulation. The prehensile tongue measures 45–50 cm, dark-pigmented for UV protection, and allows precise manipulation of thorny browse.^[4] To counter gravitational challenges from the elevated head, the cardiovascular system maintains exceptionally high blood pressure of approximately 280/180 mmHg, ensuring adequate perfusion to the brain via a powerful heart and specialized valves in the jugular veins.^[17]

Coat pattern

The coat of the Southern giraffe (Giraffa giraffa) features large, irregularly shaped brown patches that are unevenly notched and separated by lighter tan or off-white lines, creating a distinctive mosaic pattern that extends across the body and is unique to each individual, facilitating identification in research and conservation efforts.^[18]^[19] These patches vary in shade from light tan to darker rust tones, with the overall pelage providing a complex, variable texture that remains consistent throughout an individual's life barring minor seasonal or health-related alterations.^[20] Subspecies exhibit notable variations in patch characteristics adapted to their environments. The Angolan giraffe (G. g. angolensis) displays lighter brown, more angular and irregularly notched patches surrounded by off-white areas, with random speckling extending to the lower legs, often appearing paler in arid regions like northwest Namibia.^[18] In contrast, the South African giraffe (G. g. giraffa) has darker, more rounded brown patches with jagged edges on a creamy-brown background, lacking distinct patterns on the lower legs.^[18] Adult males typically exhibit intensified, darker pigmentation starting around 7–8 years of age, though this darkening is not universal and correlates more strongly with social dominance than strictly chronological age in some populations.^[21]^[22] The patchy coat serves a thermoregulatory function, with each patch functioning as a discrete "thermal window" supported by a specialized vascular network. Arteries branch radially within patches to form angiosomes, connected by "choke" vessels that enable countercurrent heat exchange, allowing giraffes to dissipate excess body heat efficiently in hot savanna environments through arteriovenous shunts and increased blood flow to the skin surface. This structure, observed in over 90% of facial and all neck patches, complements behavioral adaptations for temperature control.^[23]

Distribution and habitat

Geographic range

The Southern giraffe (Giraffa giraffa) occupies a range spanning southern Africa, with current distribution across Angola, Botswana, Eswatini, Malawi, Mozambique, Namibia, South Africa, Zambia, and Zimbabwe.^[14] This range encompasses diverse savanna landscapes, estimated at approximately 731,000 km² based on assessments incorporating protected areas and translocated populations.^[24] Core populations are concentrated in key protected areas, including Etosha National Park in Namibia and Kruger National Park in South Africa, where the species benefits from conservation management.^[14] The two subspecies exhibit distinct distributions within this overall range. The Angolan giraffe (G. g. angolensis) is primarily restricted to arid northwestern regions of Namibia and adjacent areas in Botswana, reflecting adaptations to semi-desert environments.^[2] Recent reintroductions have expanded its presence into Iona National Park in Angola, with smaller extralimital groups in the Democratic Republic of Congo, Nigeria, South Africa, and Zambia resulting from conservation translocations.^[14] In contrast, the South African giraffe (G. g. giraffa) is more widely distributed across eastern and southern savannas, occurring from southeastern Angola through eastern and northern Botswana, southern Malawi, southern Mozambique, northeastern Namibia, extensive portions of South Africa, southwestern Zambia, and Zimbabwe.^[14] Reintroductions have restored populations in Eswatini since the 1960s and in Malawi and Mozambique following extirpations in the 1990s.^[14] Historically, the Southern giraffe's range was considerably more extensive, covering broader expanses of southern African woodlands and grasslands prior to the 19th century.^[2] Significant contractions occurred during the 19th and 20th centuries, driven by overhunting and habitat conversion, resulting in local extirpations such as in Eswatini by the early 20th century and much of Mozambique by the early 1990s.^[14] Despite these losses, the species has shown relative stability compared to other giraffe taxa, with minor expansions in recent decades through protected area expansions and reintroductions in Botswana, Zimbabwe, and western Mozambique.^[24]

Habitat preferences

The Southern giraffe (Giraffa giraffa) primarily occupies open savannas, dry woodlands, and arid scrublands, favoring landscapes dominated by Acacia species in southern African regions and Brachystegia-dominated miombo woodlands in areas like Zambia and Zimbabwe.^[25]^[26] These environments allow the species to exploit varied lowland ecosystems across its range. Subspecies exhibit distinct adaptations to local conditions; the Angolan giraffe (G. g. angolensis) tolerates low annual rainfall below 500 mm, thriving in semi-arid savannas and mopane woodlands of Namibia and Botswana where water scarcity is common.^[27] In contrast, the South African giraffe (G. g. giraffa) shows a preference for riverine habitats in South Africa, utilizing proximity to permanent water sources in Acacia-rich savannas to mitigate dry-season limitations.^[25] Southern giraffes use microhabitats strategically, spending daytime hours browsing in open areas with access to taller tree canopies up to 6 m high for foliage, while selecting nighttime resting sites in sparse bushy or single-tree settings that balance cover and visibility against predators.^[28] Influenced by seasonal climate variability, Southern giraffes undertake migrations to wetter areas during prolonged droughts to access forage and water, demonstrating resilience to escalating aridity from climate change; 2025 assessments report a 50% population increase over the prior five years, underscoring adaptive capacity in core habitats.^[29]^[27]

Ecology

Diet and foraging

The Southern giraffe (Giraffa giraffa) is a selective browser, primarily consuming leaves, twigs, and flowers from over 50 species of trees and shrubs, with a strong preference for Vachellia (formerly Acacia) species such as Vachellia erioloba (camel thorn), which provide nutrient-rich foliage in their southern African range.^[30]^[31] Daily intake typically ranges from 30 to 60 kg of browse, depending on availability and individual size, allowing them to meet high energy demands despite the low nutritional density of their diet.^[32]^[33] Foraging relies on their elongated neck and prehensile tongue, up to 45 cm long, to selectively strip thorny branches and reach foliage at heights inaccessible to other herbivores, often targeting tender shoots and avoiding mature leaves.^[30] They spend approximately 70% of their active time feeding, with peaks in the early morning and late evening when temperatures are cooler and plants are more hydrated, while obtaining most hydration from foliage to minimize drinking needs.^[34]^[35] This behavior occasionally occurs in loose feeding groups, enhancing vigilance without strict coordination.^[30] Seasonal shifts adapt to resource scarcity; in the dry season, they increase consumption of fruits, seeds, and pods when leaf availability declines, maintaining nutritional balance through opportunistic browsing.^[36] Digestion is facilitated by rumen fermentation, where symbiotic microorganisms break down high-fiber cellulose into volatile fatty acids, enabling efficient nutrient extraction from fibrous material.^[37] Their feeding creates distinct "browse lines" at 3-5 m above ground, where lower vegetation is pruned, promoting bushier growth in trees and influencing woodland structure by reducing canopy density and stimulating new shoots.^[38] This selective pressure shapes savanna ecosystems, as giraffe browsing can limit tree regeneration while dispersing seeds through dung.^[36]

Predators and anti-predator adaptations

The primary natural predators of the Southern giraffe (Giraffa giraffa) are lions (Panthera leo), which target both adults and juveniles, particularly weakened or isolated individuals.^[39] Spotted hyenas (Crocuta crocuta) and leopards (Panthera pardus) primarily prey on calves, exploiting their smaller size and limited mobility.^[40] Nile crocodiles (Crocodylus niloticus) occasionally attack giraffes near water sources, such as during drinking, though such incidents are infrequent.^[40] Vulnerability to predation varies significantly by age class, with calves under three months facing the highest risk and mortality rates exceeding 50% in many populations due to intense predatory pressure.^[41] Juveniles experience substantial losses as well, with predation being a major cause of mortality in protected areas, particularly in regions with high lion densities.^[42] In contrast, healthy adult Southern giraffes are rarely predated owing to their massive size and strength, which deter most attacks, although subadults and debilitated adults remain susceptible.^[39] Southern giraffes employ several anti-predator adaptations to mitigate these threats, leveraging their exceptional height—up to 5.5 meters in males—for elevated vigilance, enabling detection of predators from distances exceeding 1 kilometer via acute eyesight.^[20] Upon spotting danger, they emit alarm snorts or bellows to alert nearby individuals and engage in defensive stomping with their powerful forelegs to intimidate or strike approaching threats.^[43]^[44] Flight is the preferred response, with giraffes capable of sprinting at speeds up to 56 km/h in bursts; mothers actively guard newborn calves by positioning themselves between the young and predators, using powerful kicks to repel attackers.^[45] The blotchy coat pattern aids in camouflage among savanna woodlands, blending with dappled light and shadows to reduce visibility to predators.^[20]

Behavior

The Southern giraffe (Giraffa giraffa) exhibits a fission-fusion social system characterized by fluid group membership, where individuals frequently join and leave groups over short periods, forming loose associations rather than stable herds.^[46] In wild populations across southern Africa, typical group sizes range from 3 to 9 individuals, though larger aggregations of up to 40 can occur seasonally, often comprising unrelated adults and juveniles.^[46] Core units consist primarily of adult females accompanied by their calves, numbering 5 to 15 members, which provide protection and facilitate cooperative foraging; these matrilineal bonds can persist for years, embedded within the broader dynamic structure.^[46] Adult males, in contrast, are often solitary or form temporary bachelor groups of 2 to 10 unrelated individuals, with associations driven by age and dominance rather than kinship.^[46] Male Southern giraffes display territorial behavior primarily during the flexible rutting periods, which last about two weeks and are unsynchronized across individuals, influenced by fluctuating androgen levels.^[47] Dominant males establish hierarchies through "necking," a ritualized combat involving swinging their necks to deliver blows with ossicones, typically occurring during mating season to secure access to receptive females; such displays rarely result in injury and reinforce social order. Male home ranges in southern African savannas span 50 to 150 km², overlapping extensively with those of females but expanding during rut to track oestrous cues, while females maintain more stable, smaller ranges of around 50 to 120 km² centered on reliable foraging areas.^[48] Outside the rut, aggression is minimal, with males tolerating proximity in shared habitats focused on vigilance against predators.^[46] Female-calf dynamics emphasize cooperative care, including allomothering where non-maternal females babysit or guard calves in crèche-like formations, allowing mothers to forage farther; this behavior enhances calf survival by distributing vigilance duties within the group. Allonursing, observed in up to 83% of females nursing non-filial calves, occurs frequently in these units, potentially as a reciprocal strategy to build alliances, though it is more common in captive settings and less quantified in the wild.^[49] Group stability averages 2 to 4 days before fission, influenced by resource availability, with females showing stronger, long-term bonds (up to 6 years) that buffer against environmental stressors.^[46] Communication among Southern giraffes relies on a mix of vocal and visual signals to maintain cohesion in sparse savanna habitats. Low-frequency infrasonic rumbles, produced at night, may facilitate long-distance contact within fission-fusion groups, though evidence remains anecdotal and unconfirmed by acoustic studies.^[46] More commonly, individuals use head tosses, snorts, and sustained humming vocalizations (around 92 Hz) for close-range interactions, signaling alarm, affiliation, or submission; these acoustic cues, combined with postural displays like neck rubbing, minimize overt aggression outside mating contexts.^[50]

Reproduction and life cycle

The Southern giraffe exhibits a polygynous mating system, in which dominant males mate with multiple females.^[51] Males assess female receptivity by tasting urine via the flehmen response, a behavior that detects pheromones indicating estrus.^[52] Breeding peaks during the rainy season, when food availability supports higher reproductive activity.^[53] Male dominance hierarchies influence access to mates, with larger, older bulls securing most copulations.^[54] Gestation lasts approximately 15 months, after which a female typically gives birth to a single calf.^[55] The newborn weighs 45-55 kg and stands about 1.8 m tall at the shoulder.^[20] Birth occurs while the mother stands, causing the calf to drop roughly 2 m to the ground, which helps it stand quickly and evade predators.^[53] Twinning is rare, occurring in less than 1% of births.^[56] Calves are weaned between 9 and 12 months of age, though they may nurse sporadically longer.^[52] Females reach sexual maturity at 3-4 years, while males do so at 4-5 years, though effective breeding for males often begins later due to competition.^[54] In the wild, Southern giraffes have a lifespan of 15-25 years.^[57] Mothers provide parental care by leaving calves in nursery groups, where multiple females collectively protect the young while foraging.^[58] In protected populations, calf survival to one year ranges from 60-70%, bolstered by reduced predation pressure.^[59]

Conservation

Population status

The Southern giraffe (Giraffa giraffa) has an estimated wild population of approximately 68,837 individuals as of 2025, representing about 49% of the total giraffe population across Africa.^[14] This marks a roughly 50% increase from 2020 estimates, attributed in part to improved survey coverage and methodologies that have captured previously underreported numbers.^[14] The population comprises two subspecies: the Angolan giraffe (G. g. angolensis) with around 15,663 individuals, which has remained stable with a slight -6% change since 2020, and the South African giraffe (G. g. giraffa) with approximately 53,174 individuals, showing strong growth of +80% over the same period.^[14] Monitoring efforts are coordinated through the Giraffe Africa Database (GAD), a centralized platform that aggregates data from aerial surveys, camera traps, and ground-based observations to track demographics and distribution across range countries.^[29] The International Union for Conservation of Nature (IUCN) classifies the Southern giraffe as Least Concern at the species level following the 2025 taxonomic recognition of four giraffe species, though the broader giraffe species complex retains a Vulnerable status due to ongoing challenges for other taxa.^[1]^[2] Overall trends indicate positive growth for the Southern giraffe, particularly in South Africa (with 29,536 individuals, +85% since 2020) and Botswana (11,477 individuals, +40% since 2020), while populations in Namibia remain stable at around 14,000 for the Angolan subspecies.^[14] Since the proposed taxonomic split in 2016 that distinguished Southern giraffe from other lineages, there has been no evidence of population decline, with the species demonstrating resilience and recovery in key strongholds.^[14]^[10]

Threats

The Southern giraffe (Giraffa giraffa) faces multiple anthropogenic threats that have severely impacted its populations across southern Africa. Habitat loss and fragmentation represent the most pervasive risk, driven by expanding agriculture, urbanization, and infrastructure development. Over the past 300 years, giraffes as a group—including the Southern subspecies—have lost nearly 90% of their historical range, with Southern giraffe habitats in countries like Angola, Namibia, Botswana, Zambia, and South Africa particularly affected by conversion to farmland and settlements.^[2] In addition, bush encroachment in savanna ecosystems, often exacerbated by altered fire regimes and overgrazing by livestock, can degrade browse quality and availability by favoring dense, less palatable woody species that limit access to preferred forage trees.^[60] These changes have fragmented remaining habitats, isolating populations and hindering gene flow. Poaching continues to pose a direct mortality threat to Southern giraffes, primarily for bushmeat, hides, and tail "hair" used in traditional medicine and crafts. This illegal hunting is especially acute in Angola and Zambia, where civil unrest and limited enforcement have enabled opportunistic killings, contributing to localized declines despite overall subspecies stability.^[14] Human-wildlife conflict further compounds these pressures, as giraffes raiding crops in agricultural fringes provoke retaliatory shootings and snaring by local communities. Disease transmission at the livestock-wildlife interface adds another layer of risk; for instance, anthrax outbreaks, originating from infected cattle, have been documented in giraffe populations sharing grazing areas, leading to sporadic die-offs in southern African reserves.^[61] Emerging threats are intensifying the vulnerability of Southern giraffes amid broader environmental shifts. Climate change-driven droughts, increasingly frequent in southern Africa, reduce water sources and forage biomass, forcing giraffes into closer proximity with human settlements and heightening conflict.^[62] Additionally, hybridization risks arise from conservation translocations, which have inadvertently mixed subspecies in regions like South Africa and Namibia; 2025 genetic assessments highlight ongoing concerns for pure lineage preservation in these reintroduced populations.^[14] Collectively, these factors have driven declines in certain Southern giraffe subpopulations, underscoring the need for targeted interventions.

Conservation efforts

Conservation efforts for the Southern giraffe (Giraffa giraffa) have focused on establishing and managing protected areas, which harbor a substantial portion of the subspecies' population. Approximately 40% of Southern giraffes reside within protected areas, with key strongholds including Kruger National Park in South Africa, home to around 12,270 individuals, and the Kavango-Zambezi (KAZA) Transfrontier Conservation Area in Botswana, which supports about 9,512 giraffes, many in Chobe National Park.^[14] These sites benefit from rigorous monitoring, habitat management, and patrols to safeguard giraffe populations.^[63] Reintroduction programs have been instrumental in restoring Southern giraffes to parts of their historical range where they had been extirpated. In Malawi, African Parks reintroduced 13 Southern giraffes to Majete Wildlife Reserve in 2018, followed by additional translocations in the 2020s, resulting in a population exceeding 29 individuals by 2025.^[64] Similar efforts in Eswatini, supported by the Giraffe Conservation Foundation (GCF), have bolstered local populations since initial introductions in 1965, with ongoing translocations enhancing genetic diversity.^[65] In Namibia, GCF-funded anti-poaching patrols and community-based conservation in areas like the Kunene Region have protected reintroduced groups, contributing to stable populations of over 2,200 giraffes on communal lands.^[66] On the international front, the Giraffe Conservation Foundation (GCF) coordinates efforts across 21 African countries, providing technical support, funding, and data for giraffe management.^[29] By 2025, 14 National Giraffe Conservation Strategies and Action Plans had been adopted in range states, guiding targeted interventions such as population surveys and habitat restoration.^[67] The subspecies' inclusion in CITES Appendix II since 2019 has regulated international trade in giraffe specimens, reducing illegal exploitation.^[68] Community involvement is emphasized through ecotourism, which in South Africa alone generates tens of millions of dollars annually, funding conservation while providing economic incentives for local protection of giraffe habitats.^[69] Additionally, GCF's Giraffe Conservation Health initiative delivers veterinary interventions to address diseases like giraffe skin disease, including diagnostic support and treatment protocols in affected populations.^[70]
