Kiwi

It is thought that around 70,000 Kiwi remain on the two islands of new Zealand. One might think that this was high, but it is estimated that there were around 12 million before humans arrived – so around 0.5% of the population survives. More importantly, this is after a great deal of work has been done by many grassroot groups, in order to shore up the population – it has been far lower in the past.

Furthermore, roughly 2% of the umanaged kiwi are lost each week (around 20 birds). When well protected, a kiwi can live 25-50 years.

 

Rowi Kiwi

The rarest species, there are only thought to be around 450 of this bird remaining (as of last full survey in 2015). It is found in Ōkārito forest and surrounds in South Westland, predator-free islands of Marlborough Sounds, this is one of 5 designated kiwi sanctuaries declared in 2000.

 

As you can see, Kiwi is not a species but a group of species. While different species have been known to breed where their range overlaps, saving each species is a separate task

Tokoeka Kiwi

Translating to Weka with a walking stick, this species

  • Haast tokoeka is Threatened – Nationally Vulnerable 400
  • Southern Fiordland is Threatened – Nationally Endangered
  • Northern Fiordland tokoeka is Threatened – Nationally Vulnerable
  • Rakiura tokoeka is At Risk – Naturally Uncommon

Stoats are the main threat, with the total population numbering around 13000

Great Spotted Kiwi

Current population 14,000, it is restricted to the upper parts of the south islands national parks – specifically Sub-alpine zones of North West Nelson, the Paparoa Range, and Arthur’s Pass. 

The largest species, it is thought to be declining by around 1.6% a year.

There are 4 genetically distinct populations Northwest Nelson, Westport, Paparoa Range and Arthur’sPass–Hurunui.

There are plans in place to save the species but time will tell if they prove successful. 

 

Little spotted Kiwi

With a population of 1670it is found on Kapiti island (1200 are found on Kapiti island, from 5 translocated to the island early in teh 20th century) and 10 other pest free areas.

They start feeding themselves and roaming alone at 5-7 days, though they will return to the nest for around 60.

Each population is either stable or growing, so the overall trend is up.

Brown Kiwi

Living in lowland and coastal native forest and subalpine areas in the North Island, there are around 26,000 of this species. Although the most numerous, the population is reducing around 2-3% each year. It is estimated that without a change it will be lost in 2 generations.

Having said this, they have a greater capacity to recover, as unlike other species, they usually produce 2 eggs each time they mate, and can produce 2 clutches a year.

There are 4 distinct subspecies which live in different areas and do not interbreed.

  • Northland brown kiwi 8000
  • Coromandel brown kiwi 1700
  • Western brown kiwi 8000
  • Eastern brown kiwi 8000

Main threats is from predation by dogs.

North Atlantic right whale population appears to be stabilizing!

The population of the north Atlantic right whales appears to have stabilized at around 350, having fallen from a peak of 483 in just 2010. In 2022 there were 356, down from 364 in just 2021.

Never a highly numerous species (it would appear) around 5500 were taken in the 3 centuries of whaling. The problem now, is that the population is so small that any looses imperil the whole species. Further, given the large amount of boating in the area, many of the remaining individuals have propeller scaring, and collisions are common and occasionally fatal.

Time will tell if this species can recover, though tourism interest is likely to give them a higher value to the local community and may help save the species.

Below is a short 5 minute video from the NOAA  (National Oceanic and Atmospheric Administration)

Dominica’s mountain chicken frog is heading to extinction faster than anything recorded before

Once so common that they were cooked as a national food on the island. Yet in just two decades, the animal is one of the rarest in the world, with an estimated population of just 21.

Growing to 20cm long and weighing over 1kg, it was one of Dominica’s apex predators. eating small mammals, snakes and other frogs.

It’s decline is notable, as its calls were formerly something that you heard across the island.

Now, silence from this frog has fallen across most of the island.

Initially, its decline was caused by a fungus, which impacted amphibians skin – important, as many amphibians breathe through there skin, and all breathe through their skin.

The breakout of this fugni led to a decline of 80% in just one year. Known to only occur on one other island (Montserrat), scientists urged strict quarantine measures to stop it arriving, but these warnings failed to have any effect.

A number of these frogs were removed in 2009 as the illness began to spread, and they are housed around the world in various zoos, such as London zoo.

In recent times, a few surviving individuals have been discovered. These appear to be naturally resistant to the chytrid fungus that is at fault.

Unfortunately, shortly after, hurricane Maria hit, and the population declined a further 80%, back into double digits.

Due to the lack of immunity to this fungus, it would appear that zoo individuals that were rescued back in 2009 are all irrelevant. Whether with such a small wild population, it is worth capturing more (it is possible that these new individuals could be bred with already captive individuals, bit this may not retain the immunity).

The remaining wild frogs are found in 2 populations, and neither are found on protected land. As such, the situation could change fast if land use changes would occur.

The conservationists in the wild are still working, but it is thought that there is only 2 years left to save the species from extinction.

“EU must cut carbon emissions 3 times faster to meet targets”

A new report has calculated that the EU is only cutting carbon emissions at 1/3 of the rate which is required in order to meet the 55% cut – from buildings, transport and agriculture by 2030

While emissions are falling, they are not falling anywhere near fast enough

Over the last 30 years, carbon emissions have dropped by 32% . while this is an impressive amount, it is far short of the promise.

The best predictions for the future, are that by 2050 the EU will have cut emissions by around 43%. While this is an important step, it is far short of what has been promised.

More importantly, at the current rate, we will have only met a further 1/3 by 2050.

The job is not done – much of the carbon emissions from the last 3 decades have been easy to achieve. They have been achieved through efficiency gains, and moving production offshore. Very little change in the EU behaviour has been required.  

An easy gain, both for individual cost, and emissions is electric cars. A faster transition is likely to save countries much money too (though it is true that at the current time, there is an issue with the tax revenue coming from fossil fuel sales.

It is far cheaper to run clean alternatives, so we must make that show in the figures.

Some governments are making efforts to help, but not in every way. For instance, in the UK, you can get money towards an electric car, but not a used one (which given the reduction in price, is likely to go further and help more. On heat pump the government is doing better – with the increase in the air-source heat pump grant, the cost to individuals has reduced to around 3500 (on average buying a heat-pump as well as installing and changing radiators to work with the lower temperature (bigger) the cost is around £11,000. However, many people have missed the advertising, and are unaware. It is true that new build homes will not be allowed to install boilers after 2025. 

However, older houses with gas boilers will be unaffected by the change until 2035. But the average cost for a new boiler, plus installation is thought to be around £4000, in 2023, meaning that for many homes, it will be cheaper to replace now.

Furthermore, while an air-source heat pump is thought to be around £50 more to run each year, should something like a thermal solar panel be added, the cost is far lower.

With carefully designed rules for builders, the switch to low cost private transport, and low cost private house heating can be cheap and obvious. At the current rate, though, this is not being met.

In the UK, clearly better understanding and education is essential, and builders need to see that adding things like thermal solar panels is a must.

Will it happen? will the EU meet our 55% target? at current speed, it is clear that this will be hard work. However, if this money is not found, we are likely to need far more in the future to adapt to the world we are creating.

3.4.5 Peleinae, Alcelaphinae, Hippotraginae

Subfamilies 3. Peleinae, 4. Alcelaphinae, 5. Hippotraginae

The subfamily 3. Peleinae (one species)

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.

Giant Sable

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

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.

Schimiter Oryx

Southern right whale

Southern right whale

The Southern right whale, like the other species in its genus, was hunted incredibly close to extinction. As a wide ranging species, when the population fell possibly as low as 300 in 1920 – so this species was saved by its low numbers, not the ban on hunting in 1935, which likely would have come too late.

It should be noted that Russia ignored this role until 1970. During these 35 years, many were killed by Russia, and when I say many, we are talking hundreds of thousands of species that everyone else was trying to save.

The population is now thought to be around 13,600, which is an impressive increase in around 100 years, of around 45 times increase. The historical population is estimated to lie between 55,000 and 70,000.

So where can they be watched? Far and away, the best known place to see them is Hermanus in South Africa, where around 100 whales congregate each year. I have seen them here, and it is a relatively easy species to see if you are in the right place. They are found from around around 20 degrees South to 65 degrees South around the world. In the past New Zealand was a fantastic place to watch them, and in recent years they returned for the first time in 80 years. They are also naturally seen in big numbers around Australia, and places like Patagonia.

Jaguarundi

Rare in much of their range, with persecution and habitat loss, we yet have time to save this creature

The Jaguarundi is a mid-sized cat, similar in size to the Ocelot – about twice the size of a domestic cat. It is found from central Argentina to Northern Mexico at the top of its range. In central and Southern America it is found east of the Andes. Secretive, and very alert, it actually tends to hunt during the day and the evenings. They live in large home ranges and low densities. In the wild they tend to be solitary or living in pairs.

Although a good climber, it generally prefers to hunt on the ground. It lives in an array of habitats from tropical rainforests, deciduous forests to deserts and thorn scrubs.

It is pretty common in Brazil, Peru and Venezuela, though it is thought to be extinct in the USA – it is obviously found in the countries in between, however due to range loss from fragmentation of habitat, as well as direct persecution as a result of taking of poultry, there are many regions where it is threatened as populations are declining fast.

The Jaguarundi shares a clade with the mountain lion (cougar), and is in the same lineage as the Cheetah

10 years to save the worlds wilderness?

1/3 of the worlds species are threatened with extinction. There are many suggestions that this is just a natural process, but in recent decades it is not. This is not happening because of natural mechanisms, it is happening because of human behaviour. Indeed, while many of these species are being pushed to extinction through loss of habitat, there are many others that are disappearing because of overexploitation by humans.
