In an article entitled Top 10 Hotspots, it was shown that between August 2012 and July 2013 deforestation increased by 28% (still recorded as the second lowest level ever). The image below is taken by google where the green indicate the forest cover and the red shows the forest that has been lost. To see the other google images taken of forests from around the world and their state of deforestation please click here!

Greetings, 
Today marked the final day of Big Cat Week, we hope that by reading our blog posts that you have a greater understanding and appreciation for not only the big cats that we covered in our posts but all the big cats that are around today. We have seen that big cats have been able to adapt, survive and conquer all the habitats that they occupy whether it be the tough winter chills in Siberia or the searing heat of Africa, many of the cats such as the Siberian tiger, the lion, the cheetah, the snow leopard  have been able to thrive in unforgiving habitats and we expect would be continuing to do so... if we hadn't made survival all the more harder for them through habitat loss and over poaching. In this post today we are going to talk about these big cats and the conservation efforts employed to protect them. 


Take a long hard look, this is the Amur Leopard they are critically endangered with only 35 remaining in the wild.

Why are Big Cats endangered?

There are many reasons as to why Big Cats are endangered, such as: Habitat loss namely the deforestation occurring in the Amazon Rainforest, and the agricultural expansion is also a major problem in parts of Africa. Human conflicts, this occurs when Big Cats predate on peoples livestock, however this is mainly because humans are encroaching on the cats territory causing them to prey on easy livestock this causes an economic loss for the farmers involved. Wildlife Trade: this factor relates to Chinese medicine where the body parts of tigers, snow leopards and leopards are used in order to cure or help certain ailments, in addition to this poaching is a huge cause of concern. 
Global warming also affects the Big Cats by affecting their habitats. Take the snow leopard for instance with global temperatures increasing and the snow beginning to melt, it pushes them further up the mountain and taking them further and further away from their prey, Lions are vulnerable to disease outbreaks that can become exacerbated by droughts these will increase in frequency as the effects of global warming increase. Rising ocean levels can cause coastal erosion which reduces the tiger habitat in India's mangrove forest. And last but not least, private ownership and loss of prey. 


The need for conservation:



Lions: On Wednesday the 5th of December the guardian released an article on the 'Big cat crisis: Africa's lions being crowded by people' where it was seen from recent satellites that farmland and agriculture had consumed open area grassland. In West Africa there are only 500 lions left. Lion populations have dropped by two-thirds just over the last half century, it was found that just 10 of the 67 lion areas are well secured and stable  and are considered to be lion 'strongholds'. 6,000 lions are in populations that are very vulnerable to a very high risk of extinction. There has been an incentive to put Lions on the endangered species list thus protecting them from hunting and poaching in the future. it is though that energetic and immediate conservative action is required. 


Tigers: Wild tiger populations have fallen drastically by 95% with three subspecies-the Balis, Caspian and Javan already extinct. Tigers are considered to be critically endangered as such the WWF (world wildlife fund) have taken action in order to save the Tigers it all comes down to improving the following threats:
Habitat and prey. Our approach is to address habitat availability, security and quality, ensuring that the tiger will have enough well-protected and well-connected areas in which to live, hunt and breed.
 
Trade in tiger parts and derivatives. Tigers are legally protected throughout their range, and any trade in tiger products is prohibited. WWF is working alongside TRAFFIC (the wildlife trade monitoring network) to investigate, expose and crack down on the illegal trade in tiger products, and to reduce markets, so that trade is no longer a significant threat to tiger conservation.
 
National and international policy. WWF and our partners will continue to work with governments to strengthen existing legislation that protects the tiger, and to help integrate tiger conservation into economic, development and land-use planning.
This map just highlights how increasingly vulnerable the tiger population is... and how much we need to help.




Cheetahs: These amazing big cats were once found in South Africa, Western Asia to India. It was found that there are fewer than 15,000 individuals left surviving in fragmented habitats in Africa. Of the five subspecies the most critically endangered populations remain in western Sahara and Iran, these populations have 60-100  individuals making the cheetah one of the most endangered cats on Earth. The main drivers towards these big cats becoming endangered was once primarily for captive trade (pelts, pets and private ownership), however now their main challenges is habitat loss and a reduction in their prey and there proximity to humans are causing many human conflicts in terms of the cheetah eating their livestock. Not all the challenges that face the cheetah are of anthropogenic origins, it was found recently that other predators that share the same habitat with the cheetah kill 90% of cheetah cubs. 
Despite the cheetahs importance for eco-tourism the IUCN has classified cheetahs as vulnerable, with the North American subspecies labelled as threatened and the Asiatic and North West sub-Saharan subspecies listed as Critically endangered. 





Conservation in action...

Those examples used are just some of the Big Cats that are in trouble, the need for conservation is crystal clear, ZSL has summed it up brilliantly what these big cats need is thriving, active and determined conservation aims in other words they need 'LIVING CONSERVATION'. It has been clearly stated that one of the main challenges facing all big cats is habitat loss, whether this be deforestation or from agricultural expansion. Sky and WWF have recently partnered up for a campaign in which they are fighting against deforestation by saving 1 billion trees. 
An amazing project in order to save the Amazon from deforestation!!
The fight for Tigers has also gone public, with the opening of the new enclosure 'Tiger Territory' at London Zoo, its aims are to combat declining tiger populations by conducting a breeding programme for the big cats. It does not stop there they have marketed a recent campaign called 'Tiger SOS' in order to raise money for tiger conservation, they also work hand in hand with 21st century tiger. To find out more about what London Zoo are doing on the front line of Big Cat conservation click on Big Cat conservation
This is the campaign that was all over London buses, make sure to check it out.
Cheetahs are no exception, multiple small scale conservation efforts have been employed in order to raise the numbers of Wild Cheetahs. These include Livestock guarding dog program, the theory is that once the cheetahs spot the dogs guarding the livestock this will put them off from pursuing the prey any further. The Cheetah Conservation Fund have formulated a plan to make it economically beneficial for farmers not to harm Cheetahs, they have done this through an eco-label called 'Cheetah County Beef' by not harming the cheetahs the farmers actually get paid more for it!! Genious. 

So, to conclude our last post on Big Cat Week we hope you have not only realized the importance that conservations plays in saving these remarkable mammals but also how organizations have already started to employ projects and campaigns to aid them in doing so. We hope that you enjoyed Big Cat Week as much as we did!! and until next year this concludes our Big Cat Week Series!!

Tigers lead a very solitary lifestyle and are rarely caught on camera... or they could just be camera shy.
We are drawing near to the end of Big Cat week soon, but before that sad last post which will be up tomorrow (make sure you read it, it is on the conservation of the cats mentioned!!) we get to tell you about an animal that has received love from all corners of the earth. Introducing to you our precious followers the majestic and royal TIGER! these cats are the biggest felines in the world with the Sumatran tiger winning 1st place for the biggest cat out of all 6 subspecies of Tiger. 
When doing the reading for this post we were very surprised that there were 6 different subspecies of Tigers and they are: the Bengal tiger, Indochinese, Malayan, Sumatran, Siberian  and the South China tiger. All six of these subspecies, have similar adaptations that they share such as heavy bones and strong muscles that are able support the tigers large frame, their claws are sharp enough to cling onto prey and their jaws hold very long canines in order to deliver that fatal blow to the back of the victims neck. 

here are some adaptations of the tiger.



Habitat: Found in East and Southern Asia, and found in territories ranging from Siberia to open grasslands and tropical mangrove swamps. 

Conservation Status: Endangered

Population: 3,200

It is thought that the South China tiger, has now gone extinct in the wild this is because there has not been one spotting for 25 years. There is a possibility that there may be a few individuals in the forests, even so those individuals would not be viable. This subspecies is already lost, can we afford to loose any more?

They may be endangered and have a dangerously low population, but these big cats are extremely adaptable! They are top predators in all the habitats that they occupy, with their ability to swim, run, jump and climb trees with ease. Now they have the skills, it  opens up an array of prey items to them including- snakes, boar, buffalo, crocodiles, deer, leopards and sometimes camels, conflicts between tigers and rhinos and elephants are pretty frequent and in these conflicts the tiger often comes of winning.


Tigers usually mate from November- April after a gestation period of about 3 months, and tend to give birth to 2-3 tiger cubs a time. When the cubs reach around 18 months old the cubs start to become independent through their ability to hunt for themselves. 
It is thought that, the cubs can grow rapidly and are able to put on 100g of weight every day.


 

 

 

 

 

The Tiger Queen:

This is just a section of Machli's  territory, it was one of her chilling out spots

You may recognize this subheading, for those of you who have been following Big Cat Week on NatGeoWild then you may have watched 'Tiger Queen', this documentary gave us a taste of the social hierarchy behind these solitary and secretive cats. It takes place in Ranthambhore national park located in Norther India one of the best tiger territories in all of India. previously you read that the tiger population had decreased to 3,200- 40% of this population is found in India and 40 of that percentage are found in this national park.
The main tiger is a tigress called Machli who has occupied a territory with an old fort, resembling a palace, she is in prime position with access to food and water all year round as such Machli has defended her territory for an astounding 11 years (the average amount of time for a tiger to keep control of their territory is 3-5 years). Machli gained this priced piece of land by defeating and banishing her own mother when she was only 3. She has produced 5 litters and raised 9 cubs to adulthood, but it is her latest litter that will bring about her demise. One of Machli's three cubs called Satra has her eye on her mothers territory and has no intention of leaving even though both her and her sisters have reached sexual maturity. 
This is Satra, revelling in her new territory and taking her place as the new queen.

It comes the day when Satra starts her take over of the throne, she challenges her weakest and most timid sister (Unis) by roughing her up a little, Unis realises that this bullying will not stop and has no other choice to leave. With Unis gone Satra turned on her last sister Athara, Satar dared not do this infront of her mother and wait until Athara leaves her mothers side and then exiles her sister Atara of her land also. Last of all, Satra challenges and then exiles her own mother leaving Satra as the new queen of Ranthambhore. However her reign was not for long, as a male tiger soon got wind of Satras irresistable scent and closed in on her territory, and he to decided he wasnt leaving this gold mine and just like that forced Satra of the land and out to find a new territory to call her home.
Overall, we found out learning about how complex a tigers social behaviour is, it was seen that territorial disputes take place between mother and daughter and between male and female tigers. 

Well that is the end of todays Big Cat Week post, we hope you learnt more about these marvellous cats. If you watched this documentary tell us what part you enjoyed more, or maybe you wtached another documentary that you really enjoyed and want to tell us about it! Leave a comment down below for us guys!
So just before we leave we thought we would show you this awesome video of how London Zoo keeps their Sumatran tigers entertained.

Greetings everyone, today's big cat week post features the Cheetah (Acinonyx jubatus). 


Females give birth to up to nine cubs after a gestation period of ninety to ninety-eight days, although the average litter size is three to five.
Habitat: Savannah and open dry grassland of most of Africa, Middle East to Turkestan 

Conservation status: Vulnerable
Population in the wild: ~7000 (

Population trend: Decreasing



Female cheetahs help their young by bringing back small of injured prey. The cubs can practice chasing and killing - developing skills they will need to perfect for independent.
Characteristics: The cheetah's chest is deep and its waist is narrow. The coarse, short fur of the cheetah is tan with round black spots measuring from 2-3 cm across, allowing it to blend easily into high dry grasses while hunting. There are no spots on its white underside, but the tail has spots, which merge to form four to six dark rings at the end. The tail usually ends in a bushy white tuft.
 
Cheetahs differ from typical big cats in several ways. Instead of stealth they use speed to run down their prey (gazelles or antelopes), assisted by blunt claws and other adaptations mentioned below. When looking at images of the magnificent cheetah, one might reassemble it's built to a racing dog, with a small head and long legs and body. The teeth and jaws of a cheetah are feeble to deliver an effective death bite, so the cheetah must bite the rear end of its prey and then bite its throat in order to suffocate its prey. 

60 second is the average time it takes for the cheetah to close in on its prey.


Cheetah's need for speed has generated an "arms race" over time, where hunting their prey has enabled it to evolve increasingly better morphological, physiological, and behavioral traits. Cheetahs and their prey (gazelles/antelopes) are evenly matched, and so success or failure is down to luck, surprise, or physical state. 
The cheetah is well adapted to hunting. Cheetahs require fast, brief bursts of speed to catch their prey. The following adaptations allow the fastest terrestrial animal to reach speeds in excess of 113kph (70mph). Firstly cheetahs have an extremely flexible spine, which coils and uncoils when the animal is striding,  helping the powerful hind legs to lengthen the stride of the animal at peak sprint. 
Secondly the cheetah's face is short and flat with the eyes arranged forward to give effective binocular vision. Additionally their eyes have an image-stabilization system to keep the prey in sharp focus when sprinting. 

The black line under each of a cheetah eye acts like an anti-glare device.

Cheetahs have large nasal passages and big lungs to allow effective cardio vascular performance. Their body has a low skeleton-to-muscle mass ratio with lighter bones and longer legs compared to other big cats. The long tail acts as a guide and allows the cheetah to achieve extremely tight turns when pursuing agile prey. 
It's shortish, blunt non-retractable claws give it permanent grip on the soil at high speeds. Closing in on prey such as a fleeing impala, a cheetah can put on an extra burst of speed over a couple of hundred meters. However cheetahs do become breathless within 30 seconds. So they must ensure they use their acute senses of hearing, sight and scent to stalk the prey and get as close as possible before chasing their prey. 

After the energy consuming effort of catching and killing a prey animal, would you blame them for resting for half an hour before starting to consume? 


Come back for Big Cat Week: Day #5 tomorrow!!
