Grey Rhebok

Grey Rhebok

The grey rhebok or grey rhebuck, locally known as the vaalribbok in Afrikaans, is native to South Africa, Lesotho, and Eswatini (Swaziland). The specific name capreolus is Latin for ‘little goat’. Generally confined to the higher areas of Southern Africa, they typically inhabit grassy, montane habitats – for example, sourveld – usually 1,000 metres (3,300 ft) above sea level, and carry a woolly grey coat to insulate them from the cold. They are not strictly limited to this habitat as they can be found in the coastal belt of the Cape, almost at sea level.

The grey rhebok is listed as “Near Threatened”, with a population of between 10,000-18,000

4. Subfamily Alcelaphinae - Sassabies, Hartebeest, Wildebeest (6 species)

Hirola

The HIrola ( also known as the Hunters hartebeest or hunters antelope) is a critically endangered species. It was named by H.C.V Hunter (a big game hunter and zoologist) in 1888. It is the only member of the genus Beatragus, and it currently has 300-500 individuals living in the wild (there are none in captivity).

It is a widely known fact, that should the Hirola be lost from the wild, it will be the last species in its genus, and therefore the first mammal genus to go extinct in Africa in the modern era. Locals have got behind this species, with 17 conservancies protecting much of the area. There are even efforts to make some of this area devoid of predators, so as to help this species bounce back faster.

Hirola

Tsessebbe, other names regularly used include Topi Sasseby and Tiang

Tsessebbee

The Tsessebbe is part of a group of so called species, which are actually subspecies (there are 5 or 6 subspecies recognized

It is closest related to the Bangweulu Tsessebe, Less so, but still very close to the Topi, Korrigum, Coastal Topi and teh Tiang subspecies. Even the Bontebok is very closely related.

  •  Tsessebbes have around 300,000 living wild
  • Korrigum (Senegalese Hartebeest) in 2004, it was numbered 2650, split between 2 national parks. They situation has not improved
  • Topi are doing well with over 100,00
  • Currently, the Tiang still number very high.

Bontebok

Found only in Southern Africa, its range includes South Africa, Lesotho and Namibia

There are 2 subspecies:

  • Bontebok, found around the western cape -2500-3000 (vulnerable IUCN)
  • Blesbok, found in the high-veld. Closely related to the Tsessebe has a population of around 120,000 (Least concern IUCN)
The majority of this is in protected reserves, meaning that the current threat is low and this species should keep growing
Bontebok

Hartebeest

Hartebeest

The Hartebeest – as many as 70 subspecies, local variants and similar have been suggested, however there is only one currently recognized species.

Overall, the species is listed as least concern with a population of around 360,000. The red hartebeest has a population of 130,000, but at the other end the Swaynes hartebeest in Ethiopia is only thought to number 800 in the wild. The Bulbul hartebeast (light blue) is extinct. The Lelwel Hartebeest(green) is considered endangered and has around 70,000 members. The western or Major hartebeest has around 36,000. What is clear, is that if you are travelling to an area where the local hartebeest is struggling, it would be we worth paying to see them, so as to give a value to them

Blue Wildebeest

  • Other names include common wildebeest, white-bearded gnu or brindled gnu.

There has been five subspecies recognized:

 

  • C.t.taurinus (Burchell, 1823), the blue wildebeest, common wildebeest, or brindled gnu Inhabits the dark brown range

  • C. t. johnstoni (Sclater, 1896), the Nyassaland wildebeest, inhabit orange (Tanzania, Mozambique Malawi)
  • C. t. albojubatus (Thomas, 1912), the eastern white-bearded wildebeest, found in the Gold (beside the Yelow)
  • C. t. mearnsi (Heller, 1913), the western white-bearded wildebeest, its range is shown in yellow
  • C. t. cooksoni (Blaine, 1914), Cookson’s wildebeest, is restricted to the Luangwa Valley in Zambia. This is the mighter brown

In addition, the distinctive appearance of a western form, ranging from the Kalahari to central Zambia, suggests that subspecies mattosi (Blaine, 1825) may also prove distinct from subspecies taurinus. The western form can be recognised even at a distance by its upright mane, long beard, and minimal brindling.

There are around 1.5 million of this species living in the wild – so they are not endangered. Having said this, given that 1.3 million (almost 90% of them live in the Serengeti ecosystem), were something to happen, we could be in a very different position..

Blue wildebeest

Black Wildebeest

Black wildebeest

The Black wildebeest is the black wildebeest or white-tailed gnu is one of the two closely related wildebeest species.  It was first described in 1780 by Eberhard August Wilhelm von Zimmermann. It came surprisingly close to extinction, having been hunted as a pest and for its meat and hide.

The current population is now thought to be around 18,000, though 7000 of this is in Namibia (outside their natural range) where they are farmed. Their conservation status is least concern

5. Subfamily Hippotraginae

Addax

The waterbuck  is a large antelope found widely in sub-Saharan Africa.It was first described by Irish naturalist William Ogilby in 1833.

Its 13 subspecies are grouped under two varieties: the common or ellipsiprymnus waterbuck and the defassa waterbuck. The head-and-body length is typically between 177 and 235cm  and the typical height is between 120 and 136cm. In this antelope, males are taller and heavier than females. Males reach roughly 127 cm at the shoulder, while females reach 119cm. Males typically weigh 198–262 kg and females 161–214 kg. Their coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward, and are 55–99 cm long. Waterbucks are rather sedentary in nature. As gregarious animals, they may form herds consisting of six to 30 individuals. These groups are either nursery herds with females and their offspring or bachelor herds. Males start showing territorial behaviour from the age of 5 years, but are most dominant from the six to nine. The waterbuck cannot tolerate dehydration in hot weather, and thus inhabits areas close to sources of water. Predominantly a grazer, the waterbuck is mostly found on grassland. In equatorial regions, breeding takes place throughout the year, but births are at their peak in the rainy season. The gestational period lasts 7–8 months, followed by the birth of a single calf.

Waterbucks inhabit scrub and savanna areas along rivers, lakes, and valleys. Due to their requirement for grasslands and water, waterbucks have a sparse ecotone distribution. The IUCN lists the waterbuck as being of least concern. More specifically, the common waterbuck is listed as of least concern. while the defassa waterbuck is near threatened. The population trend for both is downwards, especially that of the defassa, with large populations being eliminated from certain habitats because of poaching and human disturbance.

The common waterbuck is listed as least concern, while the Defassa is listed as near threatened. Only 60% of this subspecies population is in protected areas, so it could get worse, if they are lost.

Sable Antelope

Sable Antelope

The Nyala is a spiral horned species

 found in Southern Africa. The nyala is mainly active in the early morning and the late afternoon. It generally browses during the day if temperatures are 20–30 °C  and during the night in the rainy season. The nyala feeds upon foliage, fruits and grasses, and requires sufficient fresh water. It is a very shy animal, and prefers water holes to the river bank. Not territorial, they are very cautious creatures. They live in single-sex or mixed family groups of up to 10 individuals, but old males live alone. They inhabit thickets within dense and dry savanna woodlands. The main predators of the nyala are lion, leopard and African wild dog, while baboons and raptorial birds prey on juveniles. Males and females are sexually mature at 18 and 11–12 months of age respectively, though they are socially immature until five years old. They have one calf after 7 months of gestation. Its population is stable, with the greatest threat coming from habitat loss as humans expand. There are thought to be 36500 and the population is stable.

Impala

Impala

There are currently around 2 million Impala roaming across Africa.  About one quarter of these live in protected areas in Botswana, Kenya, South Africa, Tanzania, Zambia, and Zimbabwe. Around 1000 of the Black faced Impala live in the green area in the west of Africa.

7. Subfamily Antilopinae

Dama Gazelle

The Dama Gazelle is a small antelope, species with a handful of small populations acros central and western north Africa. It lives in the Sahara and the Sahel desert. 

In Niger, the Dama Gazelle has become a national symbol.

There are 3 subspecies, however the Mhorr gazell is extinct in the wild (though zoos have a number) , the dama gazelle is only kept in captivity one zoo and is very rare in the wild. 

The species is critically endangered with only 100-200 left in the wild. Given that this small population is spread over a number of areas. The number of wild semi wild and captive is around 2900, so it is just the need to save the species in the wild which is the current problem.

Bushbuck

Bushbuck

The Cape bushbuck , also  known as imbabala is a common, medium-sized and a widespread species of antelope in sub-Saharan Africa. It is found in a wide range of habitats, such as rain forests, montane forests, forest-savanna mosaic, savanna, bushveld, and woodland. Its stands around 90 cm at the shoulder and weigh from 45 to 80 kg. They are generally solitary, territorial browsers.

Although rarely seen, as it spends most of its time deep in the thick bush, there are around 1 million in Africa

Common Eland

 The common eland (southern eland or eland antelope) is a large-sized savannah and plains antelope from East and Southern Africa. An adult male is around 1.6 m  tall at the shoulder (females are 20 cm  shorter) and can weigh up to 942 kg with a typical range of 500–600 kg. Only the giant eland is (on average bigger). It was described by Peter Simon Pallas in 1766. Population of 136,000, can form herds of 500

Common Eland

Giant Eland

Giant Eland

The giant eland, (also known as Lord Derby’s eland and greater eland) is an open-forest and savanna antelope.

 It was described in 1847 by John Edward Gray. The giant eland is the largest species of antelope, with a body length ranging from 220–290 cm (87–114 in). There are two subspecies: T. d. derbianus and T. d. gigas.

The giant eland is a herbivore, living in small mixed gender herds consisting of 15–25 members. Giant elands have large home ranges. They can run at up to 70 km/h.  They mostly inhabit broad-leafed savannas and woodlands and are listed as vulnerable and have a wild population of 12,000-14,000

Greater Kudu

The greater kudu  is a large woodland antelope, you can see its distribution on the map. Despite occupying such widespread territory, they are sparsely populated in most areas due to declining habitat, deforestation, and poaching. 

The spiral horns are impressive, and grow at one curl every 3 years – they are fully grown at 7 and a half years with 2 and a half turns. Three subspecies have been agreed (one described has been rejected) :

 

  • T. s. strepsiceros – southern parts of the range from southern Kenya to Namibia, Botswana, and South Africa
  • T. s. chora – northeastern Africa from northern Kenya through Ethiopia to eastern Sudan, Somalia, and Eritrea
  • T. s. cottoni – Chad and western Sudan
They are listed as near threatened with 118,000 in the wild
Greater Kudu

Lesser Kudu

Lesser Kudu

The lesser kudu  is a medium-sized bushland antelope found in East Africa.  It was first scientifically described by English zoologist Edward Blyth (1869).It stands around 90 cm at the shoulder and weigh from 45 to 80 kg. They are generally solitary, territorial browsers.

While currently rated not threatened, its population is decreasing. It currently stands at 100,000, but it is loosing territory to humans

Common Bongo (and mountain Bongo)

The bongo  is a large, mostly nocturnal, forest-dwelling antelope, native to sub-Saharan Africa. Bongos are characterised by a striking reddish-brown coat, black and white markings, white-yellow stripes, and long slightly spiralled horns. It is the only member of its family in which both sexes have horns. Bongos have a complex social interaction and are found in African dense forest mosaics. They are the third-largest antelope in the world.

The Common (western or lowland bongo), faces an ongoing population decline, and the IUCN considers it to be Near Threatened.

The mountain bongo (or eastern) of Kenya, has a coat even more vibrant than the common version. The mountain bongo is only found in the wild in a few mountain regions of central Kenya. This bongo is classified by the IUCN  as Critically Endangered (where it breeds readily). (this is not on the map above). Only 100 live wild, split between 4 areas of Kenya

Its population is stable, with the greatest threat coming from habitat loss as humans expand. There are thought to be 36500 and the population is stable.

Mountain Nyala

 The mountain Nyala (also known as the Balbok) is a large antelope found in high altitude woodlands in just a small part of central Ethiopia. The coat is grey to brown, marked with two to five poorly defined white strips extending from the back to the underside, and a row of six to ten white spots. White markings are present on the face, throat and legs as well. Males have a short dark erect crest, about 10 cm (3.9 in) high, running along the middle of the back. Only males possess horns.

The mountain nyala are shy and elusive towards human beings. They form small temporary herds. Males are not territorial. Primarily a browser. They will grazing occasionally. Males and females are sexually mature at 2 years old.. Gestation lasts for eight to nine months, after which a single calf is born. The lifespan of a mountain nyala is around 15 to 20 years.

Found in mountain woodland -between 3000m and 4000m. Human settlement and large livestock population have forced the animal to occupy heath forests at an altitude of above 3,400 m (11,200 ft). Mountain nyala are endemic to the Ethiopian highlands east of the Rift Valley. As much as half of the population live within 200 square km (77 sq mi) area of Gaysay, in the northern part of the Bale Mountains National Park. The mountain nyala has been classified under the Endangered category of the  (IUCN). Their influence on Ethiopian culture is notable, with the mountain nyala being featured on the obverse of Ethiopian ten cents coins.

Situnga Antelope

Common Eland

The sitatunga  (or marshbuck)is a swamp-dwelling medium-sized antelope found throughout central Africa (see the map to the right. The sitatunga is mostly confined to swampy and marshy habitats. Here they occur in tall and dense vegetation as well as seasonal swamps, marshy clearings in forests, riparian thickets and mangrove swamps.

The scientific name of the sitatunga is Tragelaphus spekii. The species was first described by the English explorer John Hanning Speke in 1863.

It is listed as least concern with 170,000-200,000, and are found in 25 countries. However 40% live outside reserves, so the situation could get worse fast.

Note: these animals have been dealt with in less detail than others. Should you be interested in finding out if I have written on these animals or what exactly I said, you can find you by searching for it in the box at the bottom of the page.

Boher Reedbuck

Boher Reedbuck

The bohor reedbuck  is an antelope native to central Africa.

The head-and-body length of this medium-sized antelope is typically between 100–135 cm. Females are smaller. This sturdily built antelope has a yellow to grayish brown coat. Only the males possess horns which measure about 25–35 cm long. There are 5 subspecies:

  • R. r. bohor Rüppell, 1842: Also known as the Abyssinian bohor reedbuck. It occurs in southwestern, western and central Ethiopia, and Blue Nile (Sudan).
  • R. r. cottoni (W. Rothschild, 1902): It occurs in the Sudds (Southern Sudan), northeastern Democratic Republic of the Congo, and probably in northern Uganda.
  • R. r. nigeriensis (Blaine, 1913): This subspecies occurs in Nigeria, northern Cameroon, southern Chad and Central African Republic.
  • R. r. redunca (Pallas, 1767): Its range extends from Senegal east to Togo. It inhabits the northern savannas of Africa. 
  • R. r. wardi (Thomas, 1900): Found in Uganda, eastern Democratic Republic of the Congo and eastern Africa. 
The total population of this species is 100,000, and while it is decreasing, it is not currently low enough to justify a near threatened rating, though this might change in the near future. At the current time, I cannot see any of the subspecies being in a worse position but can change this if I find out more.

Mountain Reedbuck

 The mountain reedbuck has 3 subspecies. The western mountain reedbuck only has 450 individuals still living wild, (shown on the map in red) also known as the Adamwa mountain reedbuck which is restricted to the highlands of Cameroon. The Eastern mountain reedbuck (or Chanlers) has 2900 wild individuals, is found in parts of Kenya and Ethiopia. The Southern moutnain reedbuck, blue, (33,000) is found in the Drakensburg mountains of South Africa.

Mountain Reedbuck

Southern Reedbuck

Southern Reedbuck

The Southern, or common Reedbuck is found in Southern Africa. It is a midsized  antelope, standing 134-167cm tall

 It was described in 1785 by Pieter Boddaert. Southern reedbucks live in pairs or alone, though occasionally they will form herds of up to 20. They prefer to lie in grass or reed beds in the heat of the day and feed during sunrise and sunset, or sometimes even at night. Old reedbucks are permanently territorial, with territories around 35-60 hectares, and generally live with a single female, preventing contact with rival males. Females and young males perform an ‘appeasement dance’ for older males.  Within this territory, it is active all the time in summer, but it is nocturnal in the wet season. It regularly uses paths to reach good sites to rest, graze, and drink water. They are hunted by all the top predators in the area, including Lion, Leopard, Cheetah hyena and wild dog, as well as animals like snakes.

They are easily hunted, and combined with loss of territory to human expansion, the population is down. About 60% occur in protected reserves, but in some countries like Gabon and the DRC are though to almost be locally extinct.

Kob

Red Lechwe antelope are found in a band across Africa, including areas of Eastern, Central and Western Africa.

There are 3 subspecies:

  • The western kob, is found in the west
  • The Ugandan Kob is found in sub-Saharan Africa in South Sudan, Uganda and the Democratic Republic of the Congo.
  • The white eared Kob is found in Western Ethiopia and South Sudan (this is one of the main animals in the huge migration within sudan)
None are currently threatened with extinction. Their total population is 50,000-60,000

Red Lechwe

Red Lechwe

Red Lechewe is a species of antelope found in the south of eastern African. The red lechwe is native to Botswana, Zambia, southeastern Democratic Republic of the Congo, northeastern Namibia, and eastern Angola, especially in the Okavango Delta, Kafue Flats, and Bangweulu Wetlands. They are found in shallow water, and have a substance on their legs which allows them to run pretty fast. Total population is around 160,000

Four subspecies of the lechwe have been recognized

  • Common red lechwe (Gray, 1850) – Widely distributed in the wetlands of Zimbabwe, Botswana, Namibia and Zambia. (80,000)
  • Kafue Flats lechwe  (Haltenorth, 1963) – It is confined within the Kafue Flats (seasonally inundated flood-plain on the Kafue River, Zambia). (28,000)
  • † Roberts’ lechwe  (Rothschild, 1907) – Formerly found in northeastern Zambia, now extinct. Also called the Kawambwa lechwe.
  • Black lechwe (Kobus leche smithemani) (Lydekker, 1900) – Found in the Bangweulu region of Zambia. (50,000)

In addition, the Upemba lechwe (1000)  and the extinct Cape lechwe are also considered subspecies by some authorities. Although related and sharing the name “lechwe”, the Nile lechwe (below) is consistently recognized as a separate species.

Nile Lechwe

The Nile lechwe or Mrs Gray’s lechwe  is an endangered species of antelope found in swamps and grasslands in South Sudan and Ethiopia.

Nile lechwe can visually signal and vocalize to communicate with each other. They rear high in the air in front of their opponents and turn their heads to the side while displaying. Females are quite loud, making a toad-like croaking when moving. Known predators are humans, lions, crocodiles, cheetahs, wild dogs, hyenas and leopards. They flee to water if disturbed, but females defend their offspring from smaller predators by direct attack, mainly kicking. Nile lechwe are crepuscular, active in the early morning and late afternoon. They gather in herds of up to 50 females and one male or in smaller all-male herds. They divide themselves into three social groups: females and their new offspring, bachelor males, and mature males with territories. A males with territory sometimes allows a bachelor male into his territory to guard the region and not to copulate. They are sexually mature at 2.

Nile lechwe feed on succulent grasses and water plants. They have the special capability to wade in shallow waters and swim in deeper waters, and may feed on young leaves from trees and bushes, rearing up to reach this green vegetation. Nile lechwe are also found in marshy areas, where they eat aquatic plants.  Around 32,000 and are classed as endangered

Waterbuck

The waterbuck  is a large antelope found widely in sub-Saharan Africa.It was first described by Irish naturalist William Ogilby in 1833.

Its 13 subspecies are grouped under two varieties: the common or ellipsiprymnus waterbuck and the defassa waterbuck. The head-and-body length is typically between 177 and 235cm  and the typical height is between 120 and 136cm. In this antelope, males are taller and heavier than females. Males reach roughly 127 cm at the shoulder, while females reach 119cm. Males typically weigh 198–262 kg and females 161–214 kg. Their coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward, and are 55–99 cm long. Waterbucks are rather sedentary in nature. As gregarious animals, they may form herds consisting of six to 30 individuals. These groups are either nursery herds with females and their offspring or bachelor herds.

Heaviside’s dolphin is one of four dolphins in the genus Cephalorhynchus. The small cetacean is endemic to the Benguela ecosystem along the southwest coast of Africa. Heaviside’s are small and stocky with adults reaching a maximum length of 1.7m and weight of75 kg. The dolphin has a distinct black, grey and white body pattern, making it hard for it to be confused with any other dolphin found in the same waters. The head is cone shaped with a blunt beak. The dorsal fin is triangular in shape and centred in the middle of the back. The head and thorax are coloured light grey with darker patches around the eye. The dorsal fin,& fluke and dorsal cape are a dark grey to almost black with a band that extends forward from the dorsal fin to the blowhole. The underbelly is white, with bands that extend onto the lower rear of the body. Small white patches are located just behind the pectoral fins and a single white patch extends between these fins on the chest. Sexual dimorphism is minimal, however variation in the shape of the white patch covering the genital slit is distinct between genders. In males, the patch ends in a point, but in females widens out to cover the mammary slits.

Information on reproduction is limited for Heaviside’s dolphins, however they are thought to be comparable to Hector’s and Commerson’s dolphins. Females and males reach sexual maturity approximately between 5–9 years. Mating is thought to occur year-round, however individual females may only produce calves every 2–4 years. Gestation time is unknown. Maximum known lifespan is based on the oldest recorded individual at 26 years old. Levels of predation are unknown, however killer whales(Orcinus orca) are known predators and there is evidence of shark attack from body scars.
Heaviside’s have small home ranges of 50–80km as measured using satellite telemetry over 2–3 months and photographic resighting over up to 3 years.

 Some individuals have been resighted at the same location for up to 10 years. Prior to 2018, the “International Union for Conservation of Nature” International Union for Conservation of Nature (IUCN) listed the Heaviside’s as ‘Data Deficient’ however, as of 2017 the status was changed to ‘Near Threatened’, owing to improved knowledge on the species from multiple studies. Despite this, the overall population trend remains unknown, and there are many aspects of the species biology that remain to be studied. Heaviside’s dolphin is listed on Appendix II of the “Convention on the Conservation of Migratory Species of Wild Animals” Convention on the Conservation of Migratory Species of Wild Animals Memorandum of Understanding Concerning the Conservation of the Manatee and Small Cetaceans of Western Africa and Macaronesia. Memorandum of Understanding Concerning the Conservation of the Manatee and Small Cetaceans of Western Africa and Macaronesia. The Memorandum of Understanding was established in 2008 and aims to protect these species at a national, regional and global level.

Below here is a video of some of these dolphins, and below that is our usual list of articles on this species (we hope this number will increase in the near future).

Below this, we will add links for you to go and see these dolphins for yourself

All rhino species of the world

Javan Rhino
greater indian one horned rhino
Sumatran Rhino
White Rhino
Black Rhino

Rhino have been hit hard in the last few decades. These species are all of the currently surviving species of wild rhino. Indeed, no species of rhino have been lost in modern times – in recent times the woolly rhino was lost. Further back, there are dozens of rhino species which are only known from fossils, with as many as 45-50 different species in the Americas alone.

There are links for the black and white rhino species, as these are found in the savannah ecosystems that we have listed, however, we will add more over time as we make contact with people in the field.

Elephant death mystery solved, but no nearer to a solution

In Zimbabwe, elephants started dropping dead, no-one knew why. This has now been solved, but were not any nearer to ending the problem, and now its spreading.

It is unfortunately a fact, that in the majority of instances, sudden deaths from an unknown illness are impossible to prevent until we know more.

In total, 300 died in Botswana with another 35 dying in Zimbabwe just 2 months later. 50 more elephants have died since in Botswana.

It turns out that these animals have fallen as a result of an obscure bacteria, and scientists are concerned that it could spread to other species.

Should something similar happen amongst, say the lions of an area, we could quickly see all the lions die.

It took 3 years but a wildlife veterinarian at the Victoria Falls wildlife trust has worked out what happened. Although initially thinking it was anthrax, it was spreading in a strange way, and killing to many animals.

It turns out that a bacteria called Pasteurella Bisgaard taxon 45 was responsible. It is relatively rare, and had not been known to kill elephants. Unfortunately, in previous heatwaves, similar issues have been known to jump the species barrier and kill large numbers of antelope – particular during a heat wave. This bacteria caused blood poisoning, and mostly killed recently weaned young, which are generally weaker anyway.

It is unfortunate that outbreaks like this are so easily linked to high temperatures, as our behaviour means that these high temperatures occur more often – so deaths like this may become a way of life. Given the slow rate of reproduction in elephants, this could threaten populations if not dealt with rapidly.

The same bacteria is thought to have been responsible for 200,000 saiga antelope dying on the steppe of Kazakhstan in 2015.

Oddly, this bacteria is thought to live happily in the mouths of a variety of animals from elephants and antelope, to lions tigers and even chipmunks. If all it takes for this bacteria to become deadly is an increase in temperature, we have a hard task ahead of us.

Currently, there are 350,000 savannah elephants in Africa, but this number is already declining by around 8% a year (around 26,000 animals each year, or the equivalent of twice the total elephant population of the Kruger national park – one of the largest in the world. While it is possible to turn this around it is not easy.

African Dwarf crocodile

African dwarf crocodile

The dwarf crocodile (also known as the African dwarf crocodile, broad-snouted crocodile -a name more often used for the Asian mugger crocodile) or bony crocodile), is an African crocodile that is also the smallest living species of crocodile.

Found in lowlands to mid-height areas, in small and mid-size streams (they avoid large rivers). Generally, they live in rivers that lie in rainforest, though they will venture into the open.

They are known, in places, to be found in pools deeply isolated in Savannah. In western Gabon, there are also a group which have been living long-term in caves. It is considered vulnerable by the IUCN and is Appendix i of CITES. Where they are declining, it appears largely as a result of deforestation and hunting for the bushmeat trade. As a result, while in some regions they have a healthy population, in others (like Gambia and Liberia) they are almost lost.

In zoos in the USA and Europe there are a few of this species, however, records are not good, and quite a few of them are clearly hybrids with little conservation use. I should note, a zoo I occasionally volunteer at (marwell zoo) had one of these crocodiles until last year when it went to another zoo for breeding.

We hope to be able to list places for you to visit to see this species as soon as possible. Any of these will appear below the video and the news section (this lists all the times that this species has been mentioned (if any) in this blog). Below this, we will list all the easiest places we have connections to, to see this species.

 

African forest Elephant

African Forest elephants

There are three species of elephant, the African savanna elephant, African forest elephant and the Asian elephant. 

With the African species, Forest elephants have declined 86% between 1986 and 2015, African Bush elephants declined 60% 1965 and 2015 leaving just over 400,000. African forest elephants are thought to number between 100,000 and 150,000.

Perhaps the most scary fact is that the African forest elephant was only declared as a separate species in 2021 only 2 years ago. These species are not particularly similar – indeed the Asian elephant is more genetically similar to the mammoth, than the African savannah elephant is to the African forest elephant! 

The African forest elephants population has declined precipitably in the last few years. Given the recognition that the forest elephant is a separate species only came 2 years ago, it is hard to get accurate historic figures. Never-the-less, the combined african elephant species population was thought to be around 26 million in 1800, and 1.34 million in 1976. The estimate is currently around 100-200,000 forest elephants. One of the problems, is that the African forest elephant is an essential part of the ecosystem. There are many trees, which rely on forest elephants to carry their seeds through the forest, so that they germinate a good distance from the original plant (more than a few of the same plant in the same area, causes the pest that feeds on the tree to multiply to the point where it can kill the tree. While it is true that other animals like gorillas and chimpanzees can do this, they do it far less. Should the forest elephant be lost, the African rainforest is likely to be far less capable of of handling the various changes, like climate change that is coming.

The last strongholds are in Gabon (a survey last year suggested Gabon has 95,000 forest elephants, rather than the 60,000 that was originally thought) and the Republic of the Congo and Democratic republic of the Cong, with smaller populations remaining in other African countries (Cameroon, Central African Republic, Equatorial Guinea) and Cote d’Ivoire, Liberia and Ghana in west Africa. There is much space for forest elephants to greatly recover, if the poaching is able to stop.

Below this, you will see a video on this species, and below this is a list of any times that the african forest elephant has been mentioned within this blog.

Below this, at the bottom of the page, we hope to list places where you can go to see this species in the wild – if you work in conservation or tourism around this species, do get in touch. we would love to list you, and it costs nothing to be listed, we merely work on commission.

4 horned antelope

4 horned antelope

This is a small species of antelope that is found in India and Nepal. the sole member of its genus Teracenus (and only sharing its tribe Boselaphini with the Nilgai). First described in 1816, it has 3 recognized subspecies. It is quite hard to find, but feeds on grass shrubs herbs foliage flowers and fruit.

 

They tend to hide in long grass, and the undergrowth, which is why it is only areas like this that they are usually found in.

 

Population estimate in 2001 was put at 10,000. While they are wide spread, they live at low densities (0.7 per square km is considered healthy).

Below is a video of this species, and below this is a list of articles on this species; this is a relatively obscure antelope, but should it be written about, you will find all these articles listed here.

There are a variety of reserves where they can be seen. including Pench Kanha and Gir to name just a few. As the website grows, we hope to link to many of these places. These will all be listed at the bottom of the page.

 

Preuss’s monkey, Preuss’s guenon

Preuss Monkey

Once considered a subspecies of the LHoest monkey, it is a mountain dwelling monkey that lives in the forests of eastern Nigeria, western Cameroon and Bioko in Equatorial Guinea. 

While mostly eating fruit insects and leaves, it is known to raid human crops when given the chance.

As with many monkey species, this monkey is endangered as a result of hunting and habitat loss.

There are two subspecies of Preuss’s monkey:

  • Cameroon Preuss’s monkey, Cercopithecus preussi preussi
  • Bioko Preuss’s monkey, Cercopithecus preussi insularis
