Re-wilding in the UK

Currently, 70% of the land in the UK is given over to agriculture. Of this, just 15% is used to grow crops for human consumption. A further 22% goes towards feeding livestock. The rest is given over to livestock grazing.

This means that we give over 44% of the country to livestock, and a further 15% of the country to feed the livestock.

If growing food in a lab does indeed take off, 59% of the UK would suddenly be freed up – lab grown meat done properly could have a near 0 carbon footprint, and can be created in close proximity to the shop that will sell it -further reducing or eliminating the transport carbon footprint of food.

Now, assuming that this is to happen we would still need to keep some livestock. This would be needed to harvest cells. Never the less, we could still see a reduction of more than 99% of the livestock and land required. I do not believe that I am the only person who would be far happier satisfying my desire for meat, without the climate implications or indeed the fact that animals have to die to satisfy it (I am not a vegetarian, but over the last few years we have made efforts to reduce our meat footprint).

This would free up more than 50% of the country. What could we do with this?

Well my argument is that this land could be given over to rewilding. With this amount of land, we could suck up vast amounts of carbon a year. 50% of the UK is roughly 120,000 square kilometres. Now roughly speaking, forest suck up 500g per square m per year, or 500 metric tonnes per square km. Therefore, the UK could suck up 60 million tonnes a year. Now it is true that this is not huge compared to our emissions and we might have some other uses, never-the-less I am sure that I am not the only person that is frustrated by the lack of wilderness in the UK. Even just 10% of the gained land being given over to rewilding could make great progress in returning wilderness to the UK.

An arrested Sumatran politician – arrested for bribery, was found to have a pet Orangutan among a group of other exotic pets

There is a great deal of corruption in many parts of the world. In many places politicians are almost expected to give themselves extra benefits – indeed those who do not, are often quite notable for standing out.

In this case, after arresting the politician his house was raided, when the animals were found.

Keeping wild animals as pets can carry a 5 year jail sentence, in this case it must -he must not escape penalty for this

Can the red sea teach us how to save the worlds corals?

The coral itself is actually usually quite a dull colour, the brilliant colours of coral reefs come from the algae that lives within its coral tissue. These algae’s are called Zooxanthellae and in return for their home, the algae supply most of the corals nutrients.

The problem, is that these algae are very sensitive to temperature changes, and so if the sea remains unusually warm or cold for more than a few days, the algae leaves the corals and this is called a bleaching. This bleaching has occurred more and more recently in the last few years.

As a result of this, it is feared, that up to 90% of the corals worldwide will be lost by 2050.

This is where the red sea corals become so interesting.

The red sea coral reef looks the same as any other reef, but it appears that there is a difference, that might be the key to saving reefs around the world

Just 2 years ago, researchers found some corals in the Gulf of Aqaba, a trench between Israel, Jordan and Egypt which could withstand higher temperatures for longer. Just 1 degree above normal, sustained for a week can be enough to cause bleaching. If the temperature does not fall quickly, the corals will die. Yet here, corals have been seen to survive temperature rises above 7 degrees. It is thought that these corals have developed these abilities because they regularly suffer large temperature changes.

If they can identify corals that have this ability, and translocate them into new reefs, they will cross-breed. As the heat resistant corals are heat resistant, they are likely to survive far longer and therefore be able to pass on their heat resistant trait into the whole reef.

Given the rapidly warming planet, we only have about 30 years to act. Apart from their own intrinsic value, coral reefs are also worth roughly $600,000 per square kilometre each year, through protecting coastlines, increased tourism, medication and a whole lot more effects.

This is a fantastic possible save for the worlds reefs, time will tell if it works.

Orca have been documented killing and eating blue whales

Orca are generally regarded as the apex predator in the sea. There are obviously others that are good contenders, such as the great white shark – but when orca are nearby, great white sharks go very quiet in an attempt to not draw attention.

It would seem that nothing is too big to be food. Coordinated female lead pods of orca have been documented ramming the whale, and then eating its tongue before it dies.

It is, I suppose, not something that should be remotely surprising. Orca have developed ways of feeding on all sorts of food that would at first glance be out of reach. From rushing in towards a beach, allowing them to aquaplane up onto the beach to grab sea lions, to stunning fish with their tale – stopping them darting away, there is a fascinating range of hunting techniques that they employ.

Chimpanzees observed treating wounds of fellow chimpanzees with crushed insects

In the coastal National park of Loango – Gabon, over the course of a study of a group of chimpanzees, 19 times chimpanzees were seen catching a spefic insect out of the air, chewing it, and then inserting it into injuries on wounded fellow members of the group.

Given the relative simplicity of the treatment, any chimpanzee can apply it, but this looks like the beginning of medical treatments

A number of insects seem to have a positive impacts when applied to skin, and it is thought that these insects have an anti inflammatory effect, allowing the injury to heal faster.

The injuries are almost always as a result of fights between different groups of chimpanzees.

Rare black tiger photographed in the wild

Big cats have a range of colours that they can be found in. It is certainly true that their standard colour is more common, but in different parts of their range other colourings might be more helpful. For instance, an Amur tiger that was white may find it easier to creep up on its prey.

A black tiger photographed in the wild

On the Malay peninsular, as much as half of the leopards are black, as this gives them an advantage.

In this case, a black tiger was photographed. The animals was not entirely black, but having far wider stripes, its back looks more black with yellow stripes rather than the other way round. Fewer animals are taken out of the wild than in the past, when an animal like this would likely have been caught and sold to a zoo for many times the price that tigers normally fetch – as this tiger will increase visitor numbers.

Killing for ivory is increasing the numbers of tusk-less females

Do elephants need tusks? It is a big question. Given the fact that they have them would suggest that they do have a purpose and therefore that life without them may be harder.

In Gorogosa national park in Mozambique, tuskless females became more common after ivory poaching become common during their 15 year civil war.

A natural evolution -due to our habit of hunting elephants with the biggest tusks increasing numbers are being born without

Being born tuskless, is not an unnatural affair. Indeed, some females have always been missing tusks. However, during the war 90% of the parks elephants were poached. If an elephant is chosen for its tusks over a period of 15 years, this gives elephants born tuskless a significant advantage. Importantly, with a death rate of 90% even if the tusks make life easier in some way, they are still going to loose them.

Elephants are dangerous animals that need to be treated with respect at the best of times. They can do much damage with their trunks and likewise throwing their weight around can easily overturn a car, As a result, while loss of tusks may be an impediment (and would appear to be so, as post poaching periods tusks usually return) it is clearly not a death sentence – and as in these periods, having tusks IS, it is not surprising that the few born without rapidly come to dominate the population.

Bees killed 63 endangered penguins in south Africa

Around the planet, humans kill vast numbers of wildlife and we have pushed many to extinction.

Something we need to remember, is that we are not the only dangerous thing on earth. We need to allow each species to be able to cope with natural deaths that occur from elsewhere.

This event from a few months ago is a case in point. African penguins and African bees are both native species. It is unclear as to what caused this mass stinging event, but it is thought to be a fluke and not likely to be repeated.

While not thought of as an African species, penguins to still live in South Africa,

There are only thought to be a little more than 10,000 penguins left in South Africa, so we must watch that this does not become common, as it could push an already stressed population out of existence.

Are the days of the Nigerian gorilla numbered?

Nigeria was once a wildlife rich country. Unfortunately as a country whose population has soared over the last few decades much of the wilderness has been lost.

Afi River forest reserve in the eastern Nigeria cross river state is an forest corridor which connects small fragments of remaining gorilla habitat. However, this may well cease to be the case in the near future, as satellite data has shown significant deforestation in this area. The problem with forest corridors, is that they do not tend to be particularly wide – which means relatively small levels of deforestation can disconnect one end from the other.

These animals are important for the functioning of the local ecosystem, as well as having the ability to attract enough tourists to greatly benefit the local population – if habitat loss can be halted

Is the UK going to start being more ambitious in the animals it chooses to reintroduce?

The UK has plans to start reintroducing bison to the UK. While this is very exciting, these are large animals and when they are allowed to roam free they could hurt humans. This is highly unlikely for any one individual, but may occasionally cause significant injury when looked at as a whole. 

European bison are large animals, far bigger than anything else currently found in the UK

Why do I bring this up? The main reason that wolves have not been reintroduced to the UK, is human fears. It is true that we would likely suffer low levels of predation of livestock, yet the main fear is of attacks on humans. While wolves can act aggressively towards humans on occasion, injury to the human is incredibly rare (the wolf will almost always run before the human gets close enough to be at risk).

Lynx is an even easier animal to suggest. There are no fatal attacks on humans as far as I’m aware, and as forest specialists they are even less likely to take sheep and wolves. What’s more, while a large links watching industry is likely to Spring up, these animals are incredibly hard to see. This means that without going to extreme lengths people are unlikely to encounter them and therefore be scared by them.

Beavers have been given the right to remain. Indeed genetically correct beavers (i.e. European beavers) are multiplying rapidly, and gradually spreading out from where they were first discovered on the River Otter in Devon, with the population thought to number at least 300-500. These animals are being reintroduced all over the place. The Tayside population in Scotland is thought number at least 1000 animals and these is spread across a large part of Scotland though they still have a long way to go. Beavers however, rarely threaten human life and while they can do some damage are easier to accept.

It’s thought that the UK population of boar number at least 4000, with between 1/3 and 1/2 of these living in the forest of Dean. A pair of boar can have as many as 30 offspring in one season- meaning that without regular culling the population could very rapidly explode. They are having very positive effects on woodlands in the areas that they exist, and my hope is that some of the animals could be moved rather than being shot. Boar unlike beavers can certainly be a threat to humans, though again will only hurt people when they feel threatened. 

Other species like bears have had trials done, and likely would be far easier than lynx or wolves to live alongside. This is because as omnivores bears spend much of the year eating vegetation. It is true that some bears take to eating many sheep, but this is not common, and it is entirely possible to cull or move animals that take out this habit. Bears could also create vast tourism in areas that they live.

Animals such as pine martens should be given a helping hand. Locally extinct across much of the UK, they should be reintroduced to woodlands up and down the country. Apart from restoring a native mammal, the grey squirrel – an invasive animal which does much more financial damage each year than the pinemartin ever has, would be rapidly removed, this in turn could allow the red squirrel to start to repopulate the UK

I hope that by 2050 all these animals have thriving populations in the UK. If this was the case, then we would have rebalanced the natural world in the UK allowing it to thrive in a way that it hasn’t for centuries. Of course with precious little remaining wilderness we may find that we do not have space for anything more than a handful of some of these species. I believe even this would be of use.
