The springbok is an iconic antelope known for its distinctive appearance and agile movements. This medium-sized animal typically stands between 71 and 86 centimeters (28 to 34 inches) at the shoulder, with a body length ranging from 120 to 150 centimeters (47 to 59 inches). Adult springbok weigh between 27 and 42 kilograms (60 to 93 pounds), with males generally larger than females. They primarily inhabit the dry savannas, grasslands, and shrublands of South and Southwestern Africa, including countries like South Africa, Namibia, Botswana, and Angola.
Springbok Color Phases
Springbok display several natural color variations. The typical springbok has a reddish-brown back, a white underbelly, and a prominent dark reddish-brown stripe running horizontally along its flanks. Their face is white, marked with a dark stripe extending from the eyes to the mouth. A unique feature is a fold of skin on their back, containing a crest of white hair that can be raised when excited.
The “black brown springbok” is a distinct color variant, characterized by a dark brown to black coat. This dark coloration results from melanism, a genetic mutation causing an increased amount of dark pigmentation. Melanism in springbok results from a recessive gene combination. While born with a deep black sheen, adult black springbok may mature to shades of chocolate-brown and often develop a white marking on their face.
Other less common color phases also exist, such as the white springbok, which is predominantly white with a light tan flank stripe, and the copper springbok, displaying a reddish-brown or copper-colored coat. These variations, including the black springbok, are not subspecies but rather color phases of the common springbok. These variations highlight the species’ genetic diversity.
The Rarity of Black Springbok
The black springbok variant is less common than the standard fawn springbok. While rare in wild populations, their prevalence differs significantly in managed environments. This reduced occurrence in natural habitats can be attributed to factors such as camouflage disadvantages, making them more susceptible to predators.
Estimates suggest millions of common springbok roam the savannas of Southern Africa; South Africa alone is home to an estimated 2.5 million. Black springbok are more widely available on select private hunting and game properties, where their numbers are higher due to specific breeding practices.
Their rarity is context-dependent; while naturally infrequent, their presence in private reserves can make them seem less rare. The distinctiveness of their dark coat makes them a sought-after animal, particularly in controlled environments.
Factors Influencing Black Springbok Populations
The presence and relative numbers of black springbok are significantly influenced by human intervention, particularly in private game reserves and farms. Black springbok are often selectively bred for their unique aesthetic appeal, increasing the occurrence of the black coat for tourism and hunting. This involves breeding individuals carrying the recessive gene for dark coloration.
Animals with unique colorations, such as black springbok, may stand out more to predators, reducing their survival rates in the wild. This natural selection limits their proliferation compared to camouflaged fawn springbok. Conversely, in controlled environments, human management removes or reduces these natural pressures.
The earliest recorded sighting of a black springbok was in 1886, with another appearing in the 1950s. Ranchers then began breeding these individuals, intentionally repeating the color mutation to build herds. This deliberate breeding has led to thousands of black springbok existing today, primarily on private land.
Conservation and Management
The springbok species as a whole is classified as “Least Concern” by the International Union for Conservation of Nature (IUCN). No major threats to the long-term survival of the species are currently known, and their population trend is positive. Springbok are found in numerous protected areas across their range, including national parks and provincial reserves.
Within private reserves, black springbok are managed differently. They are often bred for their unique coloration, contributing to the game farming industry. These managed populations are utilized for various purposes, including breeding programs, tourism attractions, and trophy hunting. The hunting of black springbok is a popular activity on these properties, with no seasonal restrictions in some areas.
Concerns have been raised regarding the genetic status of these selectively bred color variants due to inbreeding. However, some management practices on private farms aim to prevent or minimize inbreeding and loss of genetic diversity. The existence of these unique color variants plays a role in the broader conversation about wildlife management, balancing commercial interests with genetic health and conservation principles.
