Company Green Grazing from Vietnam is aiming to grow and sell red seaweed, as an additive to livestock feed

Why is this important?

Around the world there are around 3 billion cattle and sheep. These produce around 231 billion pounds of methane each year, which is around 10 billion metric tonnes of methane into the air. Remember that over the first 20 years (it reduces after this) methane traps roughly 80 times the same amount of carbon dioxide. So this is the equivalent of a huge amount of carbon.

To put this in perspective, if we shrink the worlds carbon emissions to zero, but are left with all this methane, we are likely to have runaway global warming anyway.

So what does this seaweed do? It essentially causes the cows and sheep to create less methane. How much? Well, while around 100 million tonnes of this seaweed would be needed, they could eliminate 98% of the methane emissions from these livestock!

In 2019 around 34.7million tonnes of seaweed was farmed, which is leading some sceptical researchers to suggest that it cannot be done. However, if we look logically, this is already enough seaweed to reduce methane emissions by 1 third – not to be sneezed at.

Another problem, is that currently Greener Grazing is restricted to only growing 1/3 of the year, as the water temperature kills the seaweed the rest of the time. However, this could be fantastic – if cross breeding can give this seaweed the ability to cope with warmer water, they might be able to meet the whole worlds demands.

More work is needed, and other tests have proved less successful in the reduction of methane, but still, this is a field, where we might be able to green peoples behaviour without requiring them to stop eating meat.

Now, of course, if meat grown in a lab could reach price parity, it may deal with this problem overnight, though it would also eliminate many peoples source of income.

Time will tell if this company is going to have a large effect or not. We need to have farmers wanting this additive, thereby creating a valuable market for coastal communities around the world.

Porcupine family

The porcupine family is a highly varied thing. There are a total of 11 species of old world porcupines (Africa and Asia and Europe) and a total of 20 species in the Americas (new world)

Firstly the old world Porcupines: Family Hystricidae

African brush-tail porcupine

This is a species of rat-like porcupine, found in a broad belt of Equatorial Africa, right across the continent from Guinea to Kenya. 

40-50cm long and weighing 3kg, with short legs and long body, it does look like a very large rat (without a long tail). It has webbed feet, and light small quills, which are thinner and more like a brush on the tail. It makes a rattling noise when it moves.

Living in family groups of around 8 (they are not territorial and will share ranges with other groups) they defend themselves, like other porcupines by charging backwards. They are herbivorous, eating leaves, flowers and fruits from the forest floor. They also eat roots and palm nuts. They are happy to eat from carrion (dead animals) be it the remains of a kill, or simply deceased animals. They will also happily invade crops of maize, cassava and bananas to feed, when these are close to the forest. Pregnancy lasts 110 days, and young are fully developed at 2 years old, and can live to around 13 years.

Despite it being used extensively for bushmeat – it is popular, the International Union for Conservation of Nature has rated its conservation status as being of “least concern”. At the current time, it appears that the bushmeat trade is not overly pressuring the population, as it has not apparently gone even locally extinct. Still, the population should be watched, as if the amount consumed were to increase, this chould change quickly.

 

Asiatic brush-tail porcupine

It is a nocturnal (and a good digger, spending much of its time under ground) occurring in subtropical and tropical montane forests. It is found on the forest floor, often in areas with profuse undergrowth.

It makes burrows, which may be occupied by up to three animals. The female produces one or two litters a year, of a single young, after a gestation period of around 100 days.

Known to be one of the rarest porcupines in South Asia, the species is protected under Schedule II of the Indian Wildlife Protection Act, though bizarrely not listed in CITES. It has been recorded from Namdapha National Park in India. It is present in a number of protected areas in Southeast Asia.

Studies have found that while it usually looks for food at night (usually for 3 hours after midnight) this behaviour is affected by other animals, which if present in its vicinity, will mean it will only be active at dawn and dusk. They eat similar things to their African cousins (species to the left.

They are hunted for both bushmeat and their quills, but again are currently listed as least concern. This population should also be watched to make sure that this does not change.

Below is a video of this species in the wild

Cape porcupine

The Cape porcupine (also called Cape crested porcupine or South African porcupine, is a species of Old World porcupine) found in central and southern Africa. These are the largest porcupine species, as well as the largest African rodent.

They avoid dense jungle swampland, and driest of desert, and are not found above 2000m,but short of this they are widespread.

Cape porcupines eat mostly plant material including fruit roots, bulbs and bark. They have a long small intestine and large caecum, employing hindgut fermentation to break down the tough materials in their food, which includes bones and carrion, which they have been known to consume where they encounter it. They are often considered pests by local farmers, because they can feed on crops and damage trees, though in savannahs their debarking of trees may also be helping to prevent the development of denser forested environments. 

Within national parks, they are not generally seen often (partly as a result of being nocturnal). I have only seen them once in the Kruger, during a night drive. They are clearly more common than this, we have encountered their quills lying on the ground, all over the place.

Home range varies from around 2/3 -2 square km. 

Its first defence is to freeze, but it will charge backwards, if the threat continues. They can live for 10 years in the wild and even up to 20 in captivity.

Crested porcupine

The crested porcupine,  (also called the African crested porcupine) is native to North Africa (though it may be locally extinct in Egypt) and sub-Saharan Africa. It is also found in Italy, where the romans introduced it as an extra food source. While accurate estimates on the population size are not seemingly easy to find, Tuscany has a large enough population for it to be one of the more often sighted species when active (at night). Below, I have embedded some footage of an Italian Porcupine

It rarely climbs trees, but can swim well.

If disturbed, as other porcupine species, it will eventually charge backward. Given quills are not particularly clean, it can cause infection. Quill injuries have killed lions leopards and hyenas, as well as humans.

They are classed as least concern in the wild.

 

Below is a video of the crested porcupine in their native habitat. The video shows an African leopard trying to take a baby porcupine, however the parents are more than a match on this occasion

Indian porcupine

The Indian  porcupine is a rodent species native to southern Asia and the Middle East. It weighs 11-18kg and is 70-90cm long. It has similar looking quills to the African Porcupine, and has a similar diet.

 crested

While its lifespan in the wild is unknown, a captive female lived to 27 years.

It is listed as Least Concern on the IUCN Red List, and in parts of its range is common enough to be considered a pest.

 

 

.

Long-tailed porcupine

The long-tailed porcupine is a species of rodent like other porcupines. It is found in Brunei, Indonesia, and Malaysia.

Usually weighing between 1.7kg and 2.3kg, they can weigh less. They are 28-48cm long, with a tail of around 24cm. They can drop their tail to save themselves from predators, though it will not regrow. They have large paws, and they are good climbers, allowing them to browse at the top of bushes and trees. While they are good seed dispersers, their feeding on trees can kill them. They are also considered nuisance by humans, as they can destroy crops.

They are listed as least concern.

 

Malayan porcupine

The Malayan porcupine or Himalayan porcupine is a species of rodent. The head and body measurement are around 56-74 cm and the tail is about 6–11 cm. They weigh around 10 kg-18 kg. They normally feed on roots, tubers, bark and fallen fruits. They also eat carrion, insects, and large tropical seeds. They forage at night and rests during the day. It may be found singly or in pairs. It can also swim and gnaw. The sow usually has one, but twins have also been recorded.

They are hunted for meat and traditional medicine, but currently have a conservation status of least concern.

.

Sumatran porcupine

Found only on the island of Sumatra in Indonesia, this species is hunted for food. This appears to be yet to have any impact on the population as a whole, as it is still listed as least concern. This does require the scientific community to keep an eye on it, and make sure that the consumption of this species does not start causing its extinction.

.

.

 

It can weigh up to 30kn and measure up to 1m in length.

 

Sunda porcupine

The Sunda (or Javan) porcupine  is a species of rodent. It is endemic to Indonesia. Due to the popularity of the hunting and consumption of the Sunda porcupine as an aphrodisiac, the Ministry of Environment and Forestry in Indonesia has listed this species as a protected animal as of June 2018.

As of yet, the IUCN listing stays at least concern.

A short video, little choice, just some facts (sorry about the music)

 

Thick spined porcupine (borneon Porcupine)

The thick-spined  porcupine  is a species of rodent It is endemic to the island of Borneo. it is found in a wide variety of habitats ranging from natural forest to agricultural land and from sea

 level up to 1200m. Although this porcupine is hunted for food, it is not  considered a concern due to its wide distribution and high tolerance for habitat changes.

In 1996, the species was Near Threatened, but by 2008, this had improved to Least Concern.

Philippine porcupine

The Philippine porcupine (also called Palawan porcupine) is a species of rodent endemic to the island of Palawan in the Philippines. It is known locally as durian or landak.

Its population is claimed to be stable, butkilled farmers. Common in some areas, the species is found in primary and secondary forest in the mountains and in the lowlands. This species also lives in caves and under tree buttresses or in rock crevices. It endemic and restricted to the Palawan Faunal Region. 

This mammal appears to have no natural enemies.  It’s 40–90cm long, with tail 2.5–20cm  and weighs 3.8–5.4 kg.It is listed as vulnerable by the IUCN

Andean porcupine

The Andean porcupine or Quichua porcupine is a species of rodent. It is found in the Andes of northern Ecuador and Colombia as well as in Panama. This porcupine is little known, but is probably arboreal, nocturnal and solitary like its relatives. The species is thought to be uncommon to rare and the population decreasing. It is threatened by deforestation, habitat fragmentation and agriculture. It is 60-80cm long (including tail), and weighs 2kg when fully grown. The ecology of this species is little known. Its behaviour is likely to resemble that of its close relatives in being nocturnal and arboreal, and feeding on fruit and leaves.

Although it looks different, it has sometimes been described as a subspecies of the bicolored-spined porcupine, however, genetic studies have shown it to be closest to the stump-tailed porcupine . Rothschild’s porcupine of Panama was formerly considered a distinct species, but phylogenetic evidence indicates that both are synonymous.

Its IUCN rating is data deficient, but given the destruction of its forest home, it is unlikely to be doing well. It is rarely seen, making it hard to study.

Bahai hairy porcupine

The Bahia porcupine, is a New World porcupine species endemic to the Atlantic Forest of south-eastern Brazil.  Sphiggurus pallidus was formerly considered a separate species but known from two young specimens only, is a synonym of this species.

Its conservation status is least concern.

Bicoloured spiney porcupine

The bicolored-spined porcupine (Coendou bicolor) is a species of nocturnal and arboreal rodent in the family Erethizontidae.

The head and body of Coendou bicolor measure about 543 mm, and another 481 mm is tail. The body is covered with dense spines, pale yellow at the base and black-tipped, and significantly darker on the midback. The bicolored-spined porcupine has a fully prehensile tail that is primarily free of spines.

Its conservation status is least concern

Black dwarf (Koopmans) porcupine

The black dwarf porcupine also called Koopman’s porcupine, is a porcupine species from the New World and is endemic to northern Brazil. It occurs in the Amazon rainforest east of the Madeira River and south of the Amazon River. It inhabits primary forest and possibly second growth. It was described as Coendou koopmani by Charles O. Handley Jr. and Ronald H. Pine in 1992, but was subsequently found to be identical to a species described in 1818. It is nocturnal and herbivorous.

Black tailed hairy porcupine

The black-tailed hairy dwarf porcupine is a porcupine species, found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Suriname and Venezuela.

This species was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic. Its closest relatives are the frosted hairy dwarf porcupine, the brown hairy dwarf porcupine  and the streaked dwarf porcupine.

Brown hairy dwarf porcupine

The brown hairy dwarf porcupine is a species of rodent in the family Erethizontidae. Found in the Andes in Colombia and Venezuela, its natural habitat is subtropical or tropical moist lowland forests. It is not easy to study as it is only known from a few specimens and wasn’t recorded from 1925 until the 2000s. The porcupine is nocturnal and arboreal, feeding on leaves, shoots, and fruits. Habitat loss severely threatens it and it may even be extinct. Formerly listed as vulnerable, it is now designated data deficient. It is not known from any protected areas or conservation measures.

This species was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic. Its closest relative is the frosted hairy dwarf porcupine.

Its conservation status is data deficient.

Paraguaian hairy dwarf porcupine – Coendou speratus ,

The Paraguaian hairy dwarf porcupine is a porcupine species from the family Erethizontidae. It is found in Argentina, Brazil, Paraguay and Uruguay.

They have a short tail and grey brown quills and feed on fruits, ant pupae, vegetables and roots.

This species was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic. The population formerly recognized as the orange-spined hairy dwarf porcupine has been reclassified to this species. Its closest relatives are the bicolored-spined porcupine and the black dwarf porcupine.

Frosted hairy dwarf porcupine

The frosted hairy dwarf porcupine is a porcupine species in the family Erethizontidae from Colombia and northern and eastern Venezuela. It was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic. The species lives in lowland tropical rainforest and cloud forest at elevations from 50 to 2,600m. Its closest relative is the brown hairy dwarf porcupine.

It is listed as least concern

Mexican hairy dwarf porcupine

The Mexican hairy dwarf porcupine or Mexican tree porcupine is a species of rodent. It is found in Costa Rica, El Salvador, Guatemala, Honduras, Panama, Mexico, Nicaragua and Belize.  Its closest relatives are the Andean porcupine, and the stump-tailed porcupine.

This porcupine has a pale head and a dark-coloured body. The length of head and body is 32cm-45cm, with a tail ranging from 20-36cm. The maximum weight is about 2.6 kg.

 This porcupine is covered with short yellowish spines but these are hard to see, due to the long black hair covering the body. Sometimes the spines on the shoulders and back are visible projecting through the hairs. By contrast, the head is hairless, revealing the yellowish spines. The snout is pink, broad and bulbous, and the eyes are small. The tail is prehensile, spiny and broad at the base, tapering to a point. This porcupine differs from Rothschild’s porcupine in that Rothschild’s is more obviously spiny and lacks the hairy coat.

Living in the trees, it uses its prehensile tail to hold onto branches. It is nocturnal and is usually more active on dark nights. The day is spent in a hollow tree, concealed on a leafy branch, or in highland areas, in a clump of bamboos. As it uses the same hiding place each day, a pile of droppings accumulates which produces a strong odour. The diet consists of buds, young leaves, fruits and seeds. It particularly favours fruiting trees such as Inga, Cecropia, Ficus and Brosimum.

Individuals normally live alone and are silent, but in the breeding season it is more vocal, emitting screams and yowls. The female usually bears a single offspring.

Its conservation status is least concern.

 

North American Porcupine

The North American porcupine, also known as the Canadian porcupine, is a large quill-covered rodent in the New World porcupine family. It is the second largest rodent in North America after the North American beaver. The porcupine is a caviomorph rodent whose ancestors crossed the Atlantic from Africa to Brazil 30 million years ago, and then migrated to North America during the Great American Interchange when central America became a bridge between the two continents. There are 7 recognized subspecies.

  • E. d. dorsatum
  • E. d. bruneri
  • E. d. couesi
  • E. d. epixanthum
  • E. d. myops
  • E. d. nigrescens
  • E. d. picinum

It has 30,000 quills all over its body (these are modified hair. It can raise and lower them as reqiured.

It also has a strong odour, which warns away predators. It is also a good climber. Natural predators of this species include fishers (a cat-sized mustelid), wolverines, coyotes, wolves,[American black bears, and cougars, as well as humans. The only known avian predators of this species are golden eagles and great horned owls. All the quills have barbs on them, which means that even if the porcupine is killed by the predator, they often die afterwards, from infection transmitted from the quills.

They can live for 30 years, but death is usually a result of starvation, predation, falling out of a tree or being run over.

As a species, it is least concern however areas like Mexico have an alarmingly low population.

Roosmalens dwarf porcupine

Found in northern Brazil,  it has not been assessed properly, and only a few specimens have been found

It is listed as data deficient

Rothschild porcupine

The Rothschild’s Porcupine is a mysterious animal in many ways. An uncommon and nocturnal species, it has barely been studied in the field and its behavior and ecology remain poorly known. Its taxonomic status is also in dispute. Most interestingly for our purposes, the Rothschild’s Porcupine has never been recorded with certainty outside of Panama and so is officially regarded by many sources as a Panamanian endemic. With some luck, these porcupines can be found on nighttime excursions, or even at daytime roosts, at or around all three Canopy Family properties, although they are most often seen near the Canopy Tower.

The Rothschild’s Porcupine is almost entirely covered with black and yellowish-white spines, excepting its underbelly and its bulbous pink nose. Its tail is prehensile, as its lifestyle is mostly arboreal. It is active at night. Its diet includes fruits and leaves, and Canopy Family guides have observed that it is especially fond of Membrillo fruits.

The natural predator most often hunting it, is the Ocelot.

 

Santa Marta Porcupine

The Santa Marta porcupine is a rodent . It is known from dry forests on the lower slopes of the Sierra Nevada de Santa Marta and Serranía del Perijá mountains of northern Colombia, at altitudes below 500 and 1100 m, respectively, and intervening lowlands, and may also be present in nearby parts of Venezuela.

There is some debate as to whether it is a subspecies, or not, we will leave this conversation to finish before deciding.

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

Common Bongo

Nyala

Nyala

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.

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.

Mountain Nyala

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.

aaa Lake Turkana and its national parks

Lake Turkana and its national parks

Lake Turkana is a lake with 3 rivers entering it (no rivers leave, it evaporates) . It lies in the eastern part of the great rift valley. The three parks are  Sibiloi National Park, the South Island and the Central Island National Parks, covering a total area of 161,485 hectares located within the Lake Turkana basin whose total surface area is 7 million ha. The lake is the most saline in africa which means little can survive in its waters.

This area is not the largest protected zone, as it only covers around 700 square miles. The island parks are the breeding habitats of the Nile crocodile, the hippopotamus amphibious and several snake species. The lake is an important flyway passage and stopover for palaeartic migrant birds. Over the dry grasslands ranges a frail population of grazing mammals and predators. The grazers are chiefly Grevy’s zebra, Burchell’s zebra, the beisa oryx, Grant’s gazelle, the topi and the reticulated giraffe. They are hunted by the lion and the cheetah. Elephants and the black rhinoceroses are no longer seen. Closer to the dust is the cushioned gerbil (Gerbillus pulvinatus)

White Rhino

White rhino

In Africa there has been horrible decline of rhinos. The northern white rhino was as recent as 1960 still living in numbers over 2000. Found through  Chad, the Central African Republic, South-western Sudan, the Democratic Republic of Congo (DRC), and North-western Uganda. Unfortunately this population has since crashed, and while they are not yet extinct there are so few left it is unlikely to recover. Embryos have been frozen in the hope that in the near future Southern white rhinos could host these.

Unfortunately, while the southern white rhino is doing far better with 18,000 (only a 12% decline in the last decade) it is not healthy and at the rate that poaching has occurred it’s not inconceivable that this population could be largely poached out of existence in a decade. In 2021, 457 rhinos were poached in South Africa with 77 lost from the Kruger. While this is horrific, it would suggest that Kruger is finally managing to protect its rhinos more effectively. Currently only 30% of Southern white rhino live in Kruger, which in the past this percentage was far higher (as high as 80-90%). Hopefully in the future rhino poaching will go back to being a thing of the past – while Kruger has the space, it cannot stop hundreds of determined poachers, while smaller reserves can do this more easily.

In the early 1900s, the Southern white rhino population fell to 50-100, thankfully this direction changed with (they are hoping) in August this year. The problem remains, that despite it having no medicinal benefit, if a rhino horn is valuable then people living near the breadline in the surrounding area will look on it with envy. Even if locals do not do it, it is worthwhile for criminal gangs. At the moment, white rhino horn can be sold for around $60,000 per pound, and an average white rhino horn weighs just short of 9 pounds. This means that each white rhino has half a million dollars attached to its nose. 

One important thing to note, is that the name white rhino does not come from the colour of its skin. Indeed, with a white and a black rhino standing next to each other it would be hard to notice a difference in the colour of the skin. Instead, it gets its name from the afrikaans word weit which means wide – the white rhino has a wide mouth for grazing, while the black rhino has a pointed mouth for browsing.

Either place gives you a good chance to see rhino in their home.

As time passes, we hope to add more destinations for each species. There is a list of all articles on this species below the destinations available.

A trial of Silvopasture in Devon

I wrote about Silvopasture recently, there is now a trial going on down in Devon. A farmer is now planting huge numbers of trees sparsely across his land. Each row has trees roughly every 6m and each row is roughly 14m apart.

This will produce a patchwork of shade and sun.

Trees being planted are Oak Aspen and Alder – native British species.

Neighbours have suggested that he is mad, and concreting over his land would have the same benefit. Of course common sense would suggest that concreting over the land would leave far less grass than sparsely planted trees but there we are.

5600 trees will be planted across his 165 acre farm. He is taking part in a 12 year trail to see what benefit Silvopasture can have. The expectation is that the environment will benefit, but that there should also be increased productivity for the farmer.

If it can be shown that grazing sheep under sparse woodland increases yield, roughly 63% of agricultural land could have similar treatment. This could amount to hundreds of millions of trees across the country.

Studies elsewhere suggest benefits include reducing flooding increasing drought resilience, improving animal health and weight, as well as boosting biodiversity and sequestering vast quantities of carbon.

Silvopasture

Silvopasture is the idea of integrating food crops that grow high such as orchards and grapevines, but allowing grazers to graze underneath on grass. Is also often known as Agriforestry

In theory many farm areas would be capable of producing large quantities of grape vines (or other fruit) without reducing the amount of sheep that they feed on their land.

Open woodland such as this grows grass as fast as meadows, so produces as much grazing for cattle, yet absorbs many tonnes of carbon dioxide per year.
