Is Asia’s plummeting fertility rate a going to lead to a crisis, or might it help save the planet?

A large crowd

Of the slightly over 8 billion humans on earth, 4.641 billion, or just under 60% live in Asia. While this is expected to grow to 5.25 billion people in 2055 it will only be 54% (due to increasing populations elsewhere in the world) of global population at the time.

So, what is the problem? An average fertility rate of 2.1 is currently considered necessary to maintain population levels (that is, 2.1 births per female). When the fertility rate drops below this rate, there are not enough babies being born to replace all of the people dying. As environmentalists, this is good, as the human population is thought (by some) to be too high to sustainable retain long-term (estimates as to what population the earth can sustain long-term range from a relatively small 0.65 billion to an enormous 9-10 billion). Of course, it depends on what we consider as sustainable survival – for me, and I hope for most of you, what I would consider sustainable, would be a low enough population to allow all other species on earth to thrive, so I would suggest that a number near the bottom of this list is more reasonable.

Below, we will look at a range of Asian countries with large populations

Flamingo and Grebe Species

Flamingoes and Grebes

At the top of the page is an image of every species of flamingo, below you will find some information on each species. Below this, you will find the same for the grebes.

As always, should you work in tourism or conservation of any of these species, do get in touch, we are keen to help people find you. Click on list your wild place on the homepage main menu.

American Flamingo

Found in the West Indies, northern South America (including the Galápagos Islands) and the Yucatan Peninsula. It was considered cospecifc with the greater flamingo, but they are now recognized as separate species (it is also closely related to the Chilean flamingo). 

Formerly it was a culture icon in Southern Florida, but was largely extirpated by 1900. Having said this, there are vagrant flamingos in Florida, and these now often stay in the country worldwide.

There are 80,000-90,000 left in the wild, and there are 4 breeding colonies: in South America (in the Galápagos Islands of Ecuador, coastal Colombia and Venezuela, and northern Brazil), in the West Indies (Trinidad and Tobago, Cuba, Jamaica, Hispaniola (the Dominican Republic and Haiti), The Bahamas, the Virgin Islands, and the Turks and Caicos Islands), and tropical and subtropical areas of continental North America (along the northern coast of the Yucatán Peninsula in Mexico, and formerly southern Florida in the United States).

Andean Flamingo

Found in the Andes mountains of South America, it is in the same genus as the James Flamingo. Indeed, the Chilean Andea and James flamingo often share nesting sites and are relatively closely related.

It is considered vulnerable to extinction with roughly 34,000 remaining in the wild, but declining over time.

As with other flamingos they are filter feeders, though what they filter can vary from algae to small fish – which they look for in shallow salty water.

They migrate between salt lakes in the summer and lower wetlands in winter – with the capacity of covering 700 miles a day.

The threat that this species faces, is generally due to human activity of mining and other changes to their habitat.

Chilean Flamingo

Closely related to the American and greater flamingo, it is listed as near threatened in the wild with a wild population of about 200,000. Population declines are due to habitat loss and degradation, harvesting and human disturbance.

While they are only currently listed as near threatened, there is a great deal of concern about falling populations, and as such they are relatively common in zoos and there is an active breeding program..

 

Greater Flamingo

The greaterflamingo has the greatest of ranges of any species (as you can see from the map. While it is found down the East coast of Africa, it is also found on the northwest coast and the northern coast. It is also present in the middle east, and throughout much of Sothern Europe. Its range also extends into India. It is listed as least concern with a population between 550,000 and 680,000 with between 45,000 and 125,000 living in Europe – the Camargue is the most famous in Southern France

They are listed as least concern

 

James Flamingo

The James flamingo is also found on the high Andean plateau, and is closely related to the Andean Flamingo. It was thought extinct until a population was rediscovered in 1956, and the current population is thought to be around 106,000.

It is currently listed as near threatened, and on CITES appendix 2.

Lesser Flamingo

Found in Sub-Saharan Africa and India. While the smallest species, it still stands 80-90cm tall. The easiest way to tell this and the greater flamingo (with overlapping range) apart is that the greater flamingo has more black on its bill.

Estimates on the number of this species range from “above” 2 million to as much as 5 million.

They generally breed in highly caustic lakes of the great rift valley in Africa, though there are places in India and a few other places as well.

They are classed as near threatened. While their choice of nesting site protects from many predators, it is still true that many flamingos are killed. From fish eagles to baboons and big cats, there are many species who will eat a flamingo if they can get hold of it.

It is well worth seeing this animal in the wild. Seeing 750,000 lesser flamingos on lake nakuru in kenya is a site that is hard to forget.

Visits to see flamingos are well worth it, and while some live in remote places, it is usually a species which is reliable. Please get in touch if you work in tourism or conservation of this species. Click on list your wild place on the home page of the website.

Next the Grebes

While some sites claim 22 species, my list has found that some of these were extinct (indeed, according to my list there were 3 species that have gone extinct. If there are any experts out there who notice one missing, let me know

We are eager as always to help people find places to see these birds. Do let me know if you work in wildlife tourism or run a place to stay where these birds are regularly seen. Click on list your wild place on the front page of the website.

Red panda

Red Panda

Recent genetic analysis has shown that the red panda is not in fact a small bear, but instead has a closer relationship to raccoons, mustelids (badgers otters and the like) and skunks. However, what is even more fascinating, is that the next closest related family is in fact the pinipeds (seals sealions and similar) and only after this, do we find the giant panda amongst the other bears.

What is fascinating, though, is that this is the original panda. The red panda was discovered and named in 1825, while the giant panda was only discovered in 1869. I cannot find any articles on it, but I suspect that the red panda was also long-known about in China before its discovery as well.

It is not closely related to the giant panda, which is a bear, though they do share a number of features such as elongated wrist bones or “false thumbs” used for grasping bamboo (so-called convergent evolution; where distantly related species evolve the same features, because it allows each to survive well in the wild – eating what they eat (or similar). The evolutionary lineage of the red panda (Ailuridae) goes back as far as 18-25 million years ago, and there are a variety of fossils in this lineage, found in Europe and North America.

So what has happened in recent times? They were known to be found in  two different places, one of them lives in the Himalayas and the other in China. What has been discovered in recent times, is that these are not only subspecies, but separate species – and are thought to have split 250,000 years ago. However, while this is clearly true, it may well need to be forgotten – there are only 10,000 red pandas left in the wild as the top possible estimate, some suggest that there are actually only 2500 – we may have no choice in conserving both species, but have to interbreed them to help just one mixed group of red pandas, rather than loosing all red pandas from the wild. They live in coniferous forests as well as temperate broadleaf and mixed forests, favouring steep slopes with dense bamboo cover close to water sources. Most of its nutrients come from bamboo stems and leaves,

Support for these wild populations is essential. The best way to help justify their long term survival, is for local people to see them as a financial gift. This can happen quickly, with not that many people going there.

Below is a video for each, below that is a list of any articles which mention this fascinating creature, and below that, we will add any links that  will help you see these animals in the wild.

Indian Greater one horned rhino

Indian greater one horned rhinoceros

Native to the Indian sub-continent, it is listed on the red list, and is only found across 20,000 square kilometres, or 7,700 square miles This is a smaller area than the size of Wales. Unfortunately, as you can see, the rhino does not roam this whole area, to the contrary, it is only found in a few small areas.

At the last full assessment (August 2018) the population was estimated to at 3588 individuals (recent estimates suggest a population of over 4000, but I will use the numbers from 5 years ago, as it is unclear how this growth has been split within the sites). Of this number 2939 were in India, witht he rest in Nepal. In 2009 2048 of these rhinos lived in Kaziranga national park. 

Other places include translocated 18 rhinos from Kaziranga National Park and Pobitora Wildlife Sanctuary to Assam’s Manas National Park on the India-Bhutan border. As of 2017, Manas was home to 29 rhinos.

As of August 2018, the global population was estimated to comprise 3,588 individuals, including 2,939 individuals in India and 649 in Nepal Kaziranga National Park alone had an estimated population of 2,048 rhinos in 2009. Pobitora Wildlife Sanctuary in Assam has the highest density of Indian rhinos in the world with 84 individuals in an area of 38.80 km2 (14.98 sq mi) in 2009.

Indo-Pacific finless porpoise

Indo-Pacific Finless dolphin

 They are found in most of the Indian Ocean, as well as the tropical and subtropical Pacific from Indonesia north to the Taiwan Strait. Overlapping with this species in the Taiwan Strait and replacing it northwards is the East Asian finless porpoise.

They are one of the species protected by the Sundarbans national park, which lies between India and Bangladesh.

Growing to 2.3m at most, and with a weight of up to 72kg (most individuals are far, far, smaller). They eat a wide range of foods from fish and crustations to vegetation such as leaves and rice, and eggs that have been deposited on these leaves.

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.

 

Sloth Bear

Sloth bear

The sloth bear is restricted to India, with about 20000 remaining. Unfortunately their population is falling, as a result of habitat loss.

 

 These bears live alongside tigers and many other species though they are not particularly easy to find.

Over time we hope to list many places where you can visit bears and see them in their wild home, these will appear here, and a list of posts we have published on bears will appear below these links

The Bengal fox

The Bengal fox (also known as the Indian fox, and is found from the foothills of the Himalayas in the north through Southern India, and from eastern Pakistan to eastern India and South-eastern Bangladesh.

Bengal fox

They are smaller than red foxes, and is endemic to the Indian subcontinent. It has been recorded 1500m up in the mountains (at almost a mile above sea level). Generally crepuscular (active in early mornings and late evening) as well as nocturnal.

As with other foxes, generally, they are thought to pair long-term, and then live together, and that this is the standard social structure in this species. However, often pups will stay around after they are capable of living alone. There have also been groups of up to 4 adults have been recorded sharing the same den.

Although found across a large area, they tend to live at very low densities, which means that they can quickly disappear from an area, in Southern India less than 2% of bengal fox habitat is protected. They are hunted for both skin and flesh Narikuruva tribes hunt them and have done for a very long time – however, with the increased number in these tribes, and other pressures on the fox, we need to keep an eye on this situation – otherwise it could rapidly become endangered.

Snow Leopard

Snow Leopard

Snow leopards are not actually closely related to leopards. In fact they split from tigers more recently. Their worldwide wild population is thought to fall between 4000 and 6500, though as they are incredibly hard to see it is hard to count these cats accurately. Currently found only in a small part of its original range (as you can see from below).

This map shows the former and current snow leopard range. Unfortunately the red is the former range

They are found throughout the Himalayas,  including Afghanistan, Bhutan, China, India, Kazakhstan, Kyrgyz Republic, Mongolia, Nepal, Pakistan, Russia, Tajikistan, and Uzbekistan. However, remember that generally the snow leopards are free to cross borders, so their range is likely to be spotty.

It is hard to get accurate figures or indeed locations of where snow leopards are found, should you be looking at going on a snow leopard tour, they will know where snow leopards are currently found. As we link with people we will add these below. our news section – please get in touch we are keen to help people find you. These will be listed below the new section which is found directly beneath this article.
