How did the wolf disappear from Holland and why is it back

A wolf couple, photographed in Holland

The wolf disappeared from Holland around 1870, though their decline was rapid – in 1760 (just over 100 years before) people in Brabant talked of a wolf plague). In 2015, the wolf was first sighted in Holland, and while some people had said that Holland was to densly populated to allow the wolf to return, this seemed to be wrong. Wolves have returned to many of the countries around Holland, and so it seems quite odd to think that it wasn’t considered that they would cross into Holland.

In 2022, there were thought to be 4 packs of wolves (including 16 pups) as well as an individual wolf. This number has, however, grown fast in the time since, and the current number is thought to be 9 packs. What is even more exciting, it is predicted that the country can support between 23 and 56 wolf packs at a minimum – which as a wolf pack contains 6-7 wolves on average, means a total population of between 138 and 392. It should be noted, that this number is not likely to remain genetically healthy into the long-term, however Germany has a wolf population of over 1000, and while these are mostly based in the East of the country, wolves disperse great distances, so it is likely that genetic material will arrive naturally, relatively regularly. There is also a founding (if small) population of wolves in Belgium, thought to number between 15 and 24 (it is also predicted to grow by 30% a year.

There is a problem, the Hoge-Velue is one of Hollands biggest reserves, but it is owned privately. They have decided that wolves are not welcome, and are making efforts to kill those that get through their fence. This is because, without the wolf, deer are easily seen within the reserve, and they believe that the number of tourists will dry up, if it becomes hard to see the red deer, as well as the roe deer and boar.

I find this attitude rather baffling and perverse. Furthermore, when we were there last year, we spent time in the government owned reserve, which borders the Hoge-Velue, this is government owned, and wolves have settled here. I spent a number of nights within the reserve in a hide. I did not get to see a wolf (though I met a local who had a wide range of fantastic shots he had taken over the previous years), but while watching and waiting in the hide, I saw red and roe deer, as well as wild boar, in significant numbers. The idea that someone would believe that the amount of tourism visiting after wolves return would decrease, seems quite contrary to what usually happens elsewhere.

Wolves are a part of Hollands animal food web, and while it is likely to take some time to get used to living with them present once again, it is going to allow the whole ecosystem to thrive. I feel frustrated, that in the UK, we do not have a similar situation, where wolves can simply wander across an unmarked border. I do believe that in the end, wolves will return to the UK (our food web is horrifically out of balance because of a lack of predators), however, on the last occasion that it was debated, numbers from a very specific country were used to block any further discussion (Click here to read a previous article on this subject, or visit the wolf page here to get a complete list of all occasions that they have been mentioned on this site)

Badger vaccinating is found to be far more effective than culls

The UK has been culling badgers since 2013, and since then over 230,000, yet a recent study has shown that vaccination is far more successful than culling.

This trial in Cornwall, found that the rate of bTB in the study area fell to zero.

Why is this important? One of the big shames of the British government is the fact that experts have been telling them since the beginning of the cull, that it will not work. This is for a very simple reason. Badgers are required to mingle to breed, and when you cull badgers, while you can largely eliminate them in the centre of your trial area, in the area further out, you merely reduce the numbers.

As a result, young males and females that are looking for a mate are required to roam further in order to find one. As a result, any local concentrations of bTB get spread around, causing the rate of the illness to increase. The study area covered 12 farms, and they vaccinated 265 badgers.

The next step is to fund a study over a far larger area.

It should be noted, that farmers funded the study, and it has been shown that not only are vaccines more effective at eliminating bTB, but also significantly cheaper. Furthermore, they found that more badgers were vaccinated per km than were culled on nearby land – suggesting a far higher reach within the badger population.

Might we finally be at a place, where with bTB outbreaks, we can vaccinate rather than cull the badgers, so as to reduce the spread in cattle (though as I have written before, much of the spread comes from moving cattle around, rather than from the badgers anyway.

In south Africa, the bTB reservoir is found within the wild lion population. Understandably, few people would want these lions to be culled, but the ability to fire vaccine darts at them, might well be feasible in eliminating bTB here as well, where around 54% of lions have been shown to carry the illness. Whether or how fast the vaccine idea will reach South Africa is something that we will have to look out for.

Should wolves in Europe have their conservation downgraded? Are they really stable enough to be hunted again

The European commision has proposed downgrading the protection of wolves from their current strictly protected, but it has been suggested that this is not based on any science.

A total of 9 countries (The call for a re-evaluation of the annexes of the EU Habitats Directive is included in a note put forward by Finland with the support of Austria, Czechia, Greece, Italy, Latvia, Romania, Slovakia and Sweden, ahead of the EU Agriculture Council meeting of 23 January).

The problem with this move, is that while in some countries like Romania, there is a large and healthy wolf population, in other countries like France it is a very different matter. If there is a change in their status, it needs to be assessed country by country, and the European Union must really require minimum levels, otherwise, this move is highly likely to lead to the extinction of the wolf across much of Europe once again.

While living alongside wolves is not always simple, it is essential to have predators to control populations of prey, such as deer. This is not something that is easily replaced by culling, and in the UK, the likely reduction in car collisions with deer would save far more than the cost of compensation for the occasional livestock that might be lost (of course, the wolf is not currently wild in the UK and the current government sees no reason to change this).

While complicated, the interest in the wolf is high, and it is highly likely that farmers would be able to supplement their farming income by money they could be paid through ecotourism and allowing people to try to see the wolves from their land. Wolves as with many other species are still slowly recovering from centuries of persecution, they are needed for our ecosystem to flourish, and can be good for everyone, with adjustments and compensation for loss of livestock.

Paignton zoo in Devon has a baby Dik-Dik

The dik-dik is a small antelope, found in East Africa. I have been lucky enough to encounter them on many occasions, when on safari in Kenya.

They tend to move around in pairs, and the bond is so strong, it is not uncommon for them to follow each other out in front of cars.

A Kirk’s dik-dik in the wild

With a population of almost 1 million, this species is listed as least concern, never-the-less it is of great interest to see it in captivity.

Paignton zoo had a baby dik-dik arrive on new years day, so it will be even smaller than normal.

Otters not yet safe in Cumbria

The recovery of otters in the UK continues apace, but threats remain

Otters were once one of the most common predators in the UK. However, being apex predators, they are the first sign of contamination in the system. This is because, while each fish may have a low enough dose to not be impacted, when the otter has eaten many fish they are impacted.

The main threats have been chemical runoff from farms, though sewage is also a problem. 

By the 1980s, the British otter was virtually extinct from large parts of the country, only surviving in remote places, far from people and pollution. Oddly, otter hunting with special hounds was not banned until 1981, which will not have helped.

No more! Otters are now found within all counties of the UK. Now, it is true that otters are hard to see – they have always been. Generally they are species which require you to be out at strange times of the day, or just very lucky.

There are places to head where this is not the case, such as the Isle of Mull and similar islands around the UK, where the otters are dependent on the tide, so can be easier to find active in daylight.

On mainland Britain, it seems that Cumbria is an increasingly good place to look, with all suitable habitat now occupied.

Time will tell, but hopefully in the near future, this will be the case all over the UK.

Do not buy a hydrogen boiler!

The UK watchdog (amongst many other groups) have concluded that hydrogen boiler is a stupid idea. It is true that its only waste product is water and oxygen, but the cost of making the hydrogen is very high.

Should there be large quantities of hydrogen sitting around, then this might make sense – burning hydrogen is generally a very clean fuel. The problem is, that it is almost impossible to store or transport it without loosing much on route, and it is incredibly expensive to split water – the current form for the vast majority of the hydrogen on the planet. Fossil fuel companies are keen, because their old methods can extract and split hydrogen, but it will mean large carbon emissions as well, so is useless – there is a reason that it is called grey hydrogen. Green hydrogen is the only kind that will give us any profit as a world.

So why is the government supporting the switch (alongside gas focused industry). The department for energy security and net zero stated this week that the gas network ” will always be part of our energy system”. I am not sure why anyone would look at it, given an air-source heat pump is likely to be around price parity, and ground source heating even cheaper.

Installation, at the cheap end will be far cheaper than a heat-pump, but this will be more than made up for over the lifetime of the device. Furthermore, with the grants currently available, you are far better off going straight to a heat pump. This is a waste of time and money, and it would not be remotely surprising, if you had to remove it before the end of its life,as it would be costing too much

Largest offshore windfarm just powered up, and its just off UK

This vast wind farm can produce around 3.6 gigawatts of power when turned on. To put that in perspective, peak demand in the UK is currently around 61 gigawatt hours, This means that even at peak demand, this wind turbine is capable of providing roughly 5% of the UK power demand. By contrast, the average house in the UK has a low-point in power demand, during the night, when around 0.2kwh is used an hour. This equates to around 5gigawatt hours. In other words, this single wind farm is likely to be able to deal with all baseload demands of the UK housing. Of course there is other demand, from shop lights being left on, to night shifts in factories.

However, what is clear, is that this is a significant amount of power, and is likely to greatly reduce the amount of gas required to be burnt for power production.

Given that this adds to the already installed stock, we now can create around 30gwh of electricity from wind – when it is at its peak.

Now, of course the wind does not blow at this required rate to produce the maximum amount of power 24 hours a day, so these numbers are not available all day.

To put these numbers in context, in 2022, wind delivered around 26% of UK electricity. Given all the large wind farms planned, this will grow.

“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.

Aardvark

Aardvark

The Aardvark is an incredibly rarely seen animal. It is found on the savannahs of Africa, and generally lives well in and out of protected areas. It is quite a sizable aniimals, and has relatively high densities throughout its range (roughly 1 per square km in habitats that it is best suited to).

So why is it so rare to see this animal? They are one of the most exclusively nocturnal species that you can find. These are animals for which wildlife guides get excited.

The name, translated from Afrikaans means earth-pig. They are incredible diggers, and many of the burrows in the savannah are dug by them, who ever ends up using them.

The are insect eaters, and are well suited. Their claws are strong, allowing them to dig into the incredibly hard termite mounds, it has a long tongue of around 30cm, which they can direct down ant holes to get hold of their food. They have an incredible sense of smell and hearing to allow them to find the animals, and can shut their eyes and nose so as to avoid being attacked back.

Although rarely seen, there are places which have learnt how to watch them, giving you a great chance to see an animal few know about. Over recent decades, they have started appearing in zoos, with Colchester in the UK (should you visit, it is a species that needs patience, otherwise you are likely to just see a pile of aardvarks sleeping in their burrow.

It is at the top of animals I would like to see in the wild. Given, their range both in and out of reserves, I am hoping over time to build up plenty of places to see them out in the human world. Please get in touch if you are a farmer, who has these on your land.

Any of the savannah ecosystems on our wild places list will host these animals, however a great deal of luck will be needed to see them in the wild. However, we will add an special places we find where your odds are higher. For now, click here, if you want to visit a savannah ecosystem in the near future.

White-beaked dolphin

White beaked dolphin

The white-beaked dolphin  is a marine mammal belonging 

to the family Delphinidae (oceanic dolphins) in the sub order Odontoceti (toothed whales). Their distribution is shown in the map.

The white-beaked dolphin is endemic to the cold temperate and subarctic waters of the North Atlantic Ocean, most commonly in seas less than 1,000 m (3,300 ft) deep. Due to the fact they are not fully adapted to Arctic conditions, they are more vulnerable to predators, most notably polar bears. Within this wider region, white-beaked dolphins are most commonly found in four locales: on the Labrador Shelf close to southwestern Greenland, around Iceland, off the northern and eastern coasts of Britain, and off the coast of Norway. In the Faroe Islands between Iceland and the United Kingdom the White-beaked dolphin is at risk of being hunted during drive catches of the long-finned pilot whales. They may also be incidentally trapped in the purse-sein and trawl nets of the area. There are no recognised subspecies.

The dolphin may easily be misidentified as the Atlantic white-sided dolphin, although the white-beaked is commonly found further north. The white-beaked dolphin is also typically larger, and does not have yellow streaks on its side.

Below is a video (no sound) of them filmed under water off the coast of the UK. Northern parts of the UK have populations, including Lyme bay and areas around the hebrides.

They are thought to number 100,000, so are listed as least concern.
