10 Animals on the Edge of Extinction No. 10- The Javan Rhino

The Javan rhino is listed as the 1st animal on WWF’s list of the 10 world’s most endangered animals, and I for my part, had never heard of it! If you hadn’t either, we’re changing that now.

A bit about the rhino’s lifestyle

The Javan rhinos are now exclusively found on the island of Java in Indonesia, but were once found in vast regions of northeast india and Southeast Asia. They have a dark grey colour which looks almost black when wet, and their (often pink) skin folds look a bit like plated armor. Both males and females have lower incisors which resemble tusks that they use to fight. Males have one relatively short horn of about 25 cm (10 inches).

Javan Rhinos live in tropical forests, marshy areas and in the thick bush. They are mainly browsers and eat over 100 plants species they find in the forest, weigh between 900 and 2300 kg (1984-5071 pounds) and are between 3 and 3.2 meters (10- 10.5 feet) long.

How endangered are we talking?

Javan rhinos are the most endangered animal species of the world, and thus the most endangered of the 5 rhino species too. Their habitat has been reduced to only the Ujung Kulon National Park where only an estimated 70-75 rhinos live. They have extreme problems to combat and can only survive with human protection and aid.

Why are they endangered?

The population left in the national park is being intensely monitored and studied and we know that the Javan rhino is suffering under

The low genetic diversity: Due to the very small population left, the genetic diversity leaves much to be desired. And the less genetic diversity there is, the more difficult is it for the species to adapt and survive, as anyone who listened in bio class knows.
Natural Disasters: The Javan Rhino’s last remaining habitat is located in an area extremely prone to tsunamis and near a volcano. On top of that comes climate change and rising sea levels which also threaten the park.
Invasive Species: The Arenga Palm has overtaken parts of the park, reduced habitat quality and the plants that naturally occur there by spreading extremely quickly and blocking the light, making it hard for the plants the Javan Rhinos eat, to grow. There is also the Javan Banteng, an invasive species whose diet overlaps with that of the Javan rhino. This doesn’t necessarily seem problematic at first, but considering that the Javan Rhino needs about 50 kg of food daily, no competition is welcome.
Illegal trade and poaching: One of the main reasons Javan rhinos are so endangered are naturally humans, the excessive demand for rhino horns and its use in traditional Chinese medicine for example are widely known to be a problem for all rhinos.
Reduced habitat: As these rhinos thrive in the tropical rainforest, they have naturally been a victim of deforestation and human invasion of the natural world, and continue to be closed in upon by people.
Disease: Javan rhinos seem to catch a lethal disease from water buffalos and in recent years, 4-5 have been found dead, with their horns still intact.

What’s being done?

There are different approaches planned and various efforts already running to help the Javan rhino survive:

The Arenga palm is being cut down and moved from the rhino’s habitat
WWF is planning to establish a second population in a different location
The Javan rhinos are constantly being surveyed and protected to best efforts in the national park

This was just a quick introduction, people often have little time, so I try to keep this short so that they feel they have the time to read about nature and animals. But as I was collecting my information from these websites, I really enjoyed looking into the rhino-problem itself, but also these organisations. So if you’re further interested in this, I would check out the websites I used as my sources!

On top of that is this the 10th Endangered Animal post, and the series is therefore finished! I’m really excited to have started and ended this series, although E. B-P did most of the work in between. Nonetheless I hope you enjoyed this series and can now brag with your knowledge about random animals.

Have a great day guys!

16.08.2020 Animal of the week: Elephant

Hello. On the 12th of August it was International Elephant Day, so we decided that this week's post should be about elephants. Elephants are the largest living land mammals. There are three types of elephant; the African bush elephant; the African forest elephant and the Asian elephant. African elephants have larger ears, whereas Asian elephants have smaller ears. Elephants use their trunks to breath, bring food and drink to their mouths and to grasp objects. Elephants' legs are like pillars. They carry the Elephant's massive weight. African bush elephants weigh 6000kg, Asian elephants weigh 4000kg and African forest elephants weigh 2700kg. Basically, they are very heavy.Elephants eat grasses, small plants, bushes, fruit, twigs, tree bark, and roots. Elephants can live up to 70 years old in the wild. They communicate by sight, touch and smell. Sadly, these wonderful mammals are in danger. African elephants are listed as vulne

Why Don't People Switch To Electric Cars? || Green World Blog

Hi Everyone! The previous post in this series really blew up, so thank you so much for your support on that one. In this article, I wanted to discuss why people are not switching to electric cars, and why the transport industry still has a way to go in terms of reaching net zero. If you missed the first part of this post, then click here to read it! ! I talked in the post linked above, about why people should switch to electric cars, while also taking into account the potential issues with them, and coming to a conclusion about should everyone switch to electric cars. In this post, I wanted to delve further into the topic of why people don't switch to electric cars. The cost is one of the main issues at the moment. To own an electric car, you need a reliable electricity supply, which is not readily available for everyone in the developing world, let alone the cost of buying the vehicle in the first place. The cost of the vehicle coul

April 2021 Factfile - some news from the past month and animals that you voted for

Hi Everyone! In this factfile we are bringing you some more news from the past month, animals you voted for, an exciting announcement and more! News: The Guardian reports that 'the new research shows that since the 1990s, the loss of hundreds of billions of tonnes of ice a year into the oceans resulting from the climate crisis has caused the poles to move in new directions.' Previously, the poles could only move due to ocean currents and other natural factors. Apparently, glacial losses accounted for most of the change but some were also due to the pumping of groundwater which once pumped up by humans isn't replaced. This shows just how much climate change is having an impact on our beautiful planet. You may have heard about M&S's plans to release 30 million honey bees to the countryside. It has faced many complaints from experts saying that this could damage the balance of natural pollinators. It is important t

Animals 41 - 45 in our '50 incredible animals' series

Hi everyone, 41. Ghost shark So first of all, this is a real animal and not a horror movie! Ghost sharks, often referred to as chimaeras, include around 50 species. They mostly live in the deep ocean and are seldom seen, hence the name. They can be found all over the world. Some species have a large range, for example, the rabbit fish which inhabits the entire northern Atlantic Ocean, or a small range, like the Galapagos Ghost shark which only lives in the waters around the Galapagos . Not much is known considering their population status however they are currently not considered threatened. It is assumed that they reproduce in the same way as most sharks. Not much else is known about ghost sharks. They are as mysterious as their name suggests! 42. Sea pig Again, this is a real animal! But it is not in any way like a pig (I have no idea why they called it a sea pig ). It is a type of sea cucumber, that lives in the ocean depths. Their bodies are fille

Top tips for Christmas

Hello everyone, This post is all about how to help the environment over Christmas. 1. Try not to travel massive distances by plane Christmas is the time of the year to get the whole family together, not go on holiday. Enjoy the environment around you, talk to the friends and neighbours that you normally talk to, you don't need to fly half way aroudn the globe for just one week. Of course, if you are travelling to visit family this doesn't really count. 2. Christmas trees; Most people buy a new Christmas tree every year and then throw it away in January. The more environmentally friendly option is to buy a small Christmas tree in a pot and put it out in the garden and let it grow for the rest of the year and then bring it in again next Christmas. There are quite a few advantages when doing this. 1. Planted trees don't drop loads of needles. 2. It saves money because you don't have to pay for a new tree every year. 3. It saves t

Eco system Galápagos: Part 1 Geography

Hello and welcome to the first post about the Galapagos Islands. Currents and Winds The volcanic islands of Galápagos started to form 4 million years ago. Where they lie, is unique. They are situated directly on the equator, on the Nazca tectonic plate. The Galapagos Islands are on the crossroads of three currents. The cold South Equatorial Current flows westward towards Galapagos. The warm Panama Current runs in from the north. And finally, the deep sea Cromwell Current runs from the west. The Galapagos Islands are also where the Northeast Trade Wind meets the Southeast Trade Wind. Galapagos Hotspot 21 Volcanoes make up the Galápagos Islands with 13 still active. The reason for this volcanic activity is a giant hotspot under the island. A hotspot is a gigantic column of super heated molten lava, rising up towards the surface. It is immense; at least sixty miles (97 kilometers) across and 1800 miles (2897 kilometers) deep. It connects the islands to

Major ocean currents and how they affect global temperatures

Hi everyone, This week we're talking about ocean currents. Ocean currents are part of the ocean's circulation system and influence local and global weather patterns. They are produced by gravity, differences in water density, winds on the ocean surface and Earth's rotation on its own axis. They cause the movements and exchanges of different ocean properties such as salinity, temperature and nutrients. Ocean currents can flow at speeds of up to 4m per second however most flow at speeds between 5cm and 50cm per second. Weather patterns and ocean currents constantly influence one another. Ocean currents follow similar paths as global wind do, transferring heat from the equator to polar regions. They create and influence ecosystems worldwide, especially marine ones. However they also spread plastics and microplastics around the world far from their original source. This system of ocean currents is often referred to as a global conveyor belt. Today w

Killing invasive species: necessary?

Hi everyone, Today's topic is a rather controversial one: is killing invasive species necessary? We'll take it apart for you to come up with your own opinion. Enjoy! Definition Firstly, let's clarify what an invasive species is. An invasive species is a species that is not native and most likely causes harm to the ecosystem where it now lives. This does not include animals that migrate to another area. Why is it a problem? Depending on the species and the ecosystem, invasive species can cause a lot of harm to their surroundings. Often invasive species have no predators in their new habitat and reproduce in such large numbers that they massively overpopulate, causing death for other species. Or they bring sicknesses the local animals are not accustomed to, and that kills them. For example black and brown rats are an invasive species on the Galapagos Islands : Black and brown rats were introduced to the Galapagos Islands in the 17th ce
