Ah yes the nice EU experiment where it uses the Netherlands for as their experimentation grounds. The goal of having more wild life is lofty, but it makes no sense in the netherlands . For the people who don't know, there weren't wild wolves up to 2015. There now are many and they've attacked people, horses and wiped out complete herds of sheep. The amount of sheep they are killing is increasing exponentially. (not using exponentially lightly here.) Proponents during the 2015-2020 era said that it would never come to this situation, alas.

Sure... It's a developed productive high tech country with agricultural exports leaving Russia in the dust despite 400 times smaller land size, but let's condemn it because it's "safe"

Also ask the farmers, fishers, ASML employees, the police dealing with gang killings and Netherlands being the biggest exporter of ecstasy and European gateway for coke how it's a "holiday park";)

NL has the biggest port in Europe, they get to be the biggest traffic channel for illegal goods. The only one who could've changed that would've been the one to eestablish the country there.

i mean singapore port handles way more traffic... but then it has very strict anti drug laws

Well I guess we differ there then, I do like not having to carry a rifle or sprays when i walk outside (we are not allowed). I also like livestock and kids not having to fear a predator that we drove to the outskirts.

I do wonder where you live in the Netherlands and if you just find it convenient to talk about the rural parts without having to face the consequences.

ongediertebestr | 12 hours ago

This is everything wrong with the netherlands. The over the top complaining of the “farmers” (factory operator would be more accurate).

Wolves stay away from humans, there have been zero human deaths by wolves. The whole anti wolf movement is just propaganda by the “farmers”.

hbogert | 11 hours ago

Very demeaning way of people making their livelihood.

> Wolves stay away from humans, there have been zero human deaths by wolves.

No they don't always stay away, plenty of confirmed stories. Just because there's no deaths yet, does it mean you can continue until it does happen? People have already been attacked.

derriz | 12 hours ago

Wolves generally don't attack people, though, do they?

There are no recent (last half century) documented cases of wolves killing people in Europe as far as I know. The few times people have been bitten by wolves they've been feeding them or doing other stupid stuff.

Freak_NL | 11 hours ago

Nope. The basic rule is that you don't do things with wolves you shouldn't do (like feeding them and thus gradually letting them get comfortable around humans), and that you don't do boneheaded shit like leaving a small child alone in nature (which is common sense in most of the world). For a wolf a three year old child is just about the same as a boar or small deer.

Anyone over the age of 12 though? Wolves won't bother you unless you've managed to fuck up nature to such an extent that they can't find their usual diet (deer, boar, etc.), and even then attacking an adult is really desperate.

There was an interesting interview with an Italian expert about wolves and people in the news this week:

Well it's easy to have zero wolf attacks when there are zero wolves. We also have zero hyena attacks.

There are more than zero wolves in many places of Europe.

AlotOfReading | 3 hours ago

As someone who lives in a country with wolves and other apex canids (to the point where we have legal hunting seasons for them), I really don't understand the supposed "consequences" here. Canid populations just aren't an issue. There are no children living in fear (rather, we have to keep kids from trying to approach the cute animals...), nor are the occasional depredation events more than a minor annoyance. If a wolf or big cat in particular eats your lifestock, you file a form with the government for market-value compensation and complain about the hassle at the bar.

lifestyleguru | 11 hours ago

Honestly wolves work with smell and will actively avoid humans. Opposite to domesticated dogs which at the sight of a human will bark at a human and oftentimes attack. Having lived in multiple regions in Europe with statistical presence of wolves I have zero encounters with wolves and dozens of occurrences where domesticated dog was barking at me or chasing me.

Surely there are benefits to this. What are they? Could you provide a steel man of the opposition, please?

tormeh | 12 hours ago

Population control, preventing overgrazing, stuff like that. However, the Netherlands (unlike most countries) is basically a big farm with practically no wild nature, so humans manage that stuff already. Maybe I'm exaggerating a tad, but I don't get what benefit wolves have in the Netherlands specifically.

tourmalinetaco | 11 hours ago

To the average Dutchy? Not much. To the average European? Also not much. Animal preservation is well and good and all but anything wolves can do for the deer population humans can do. Though Idk how it is in NL, but wild boars are nasty fuckers and we do good to keep them down, so there might be some benefit there, though not sure if damage by boars if offset by damage by wolves.

hbogert | 11 hours ago

The promise that the ecosystem would manage itself and wolves would just pick the least fit of the herd. It's shown they just like to kill for the thrill. There are cases of 30 sheeps per night in one site. 'Just Place fences' is a common heard thing, however wolves are smart and will just jump over or dig underneath. If you want to make a proper barrier with concrete is just practically unaffordable for the farmers.

Livestock guardian dogs and other methods are common around the world where predators still exist in the environment. Why can't the Dutch use them?

Although a quick googling appears to show that there is a compensation scheme in place for livestock killed by wolves, although I see a lot of commentary on it being insufficient.

KaiserPro | 11 hours ago

Its larger animal control.

Wildboars can be quite destructive, as are deers. the wolve was the natural preditor of those animals so the only thing that kept them in check was either hunting, disease or food availability.

In the UK deer over population is a problem for forestry as they eat saplings. So we spend a lot of cash hunting them (good food source, but not widely distributed in shops) Wolves stop that.

For the netherlands sspecifically, where there are deer they eat the trees that provide bank stability (ie willows) Less of a problem now but they also eat the pioneer species that were used to build polders.

Deer carry disease for cattle and sheep as well. although cows in holland are fairly hemmed in, ticks and fleas are less so.

Scarblac | 12 hours ago

Primarily because sheep owners refuse to install good fences.

throw310822 | 12 hours ago

Hmm. Well, not sure about this. If you put yourself in the shoes of the wolf, sheep are abundant, free, delicious everything- their "economy" is exclusively food-bound. Not sure what kind of fences would keep them out, and how expensive would they be- and how long they would last.
That’s not true. Wolves are incredibly smart animals and will find and exploit weak points in otherwise expensive fencing systems. They also jump surprisingly high. Moreover, once they manage to cross a fence they do not kill to feed. Instead, they slaughter entire herds of sheep for the sport of it. I personally think wolves are incredible animals, but their sudden reintroduction in the Netherlands feels ill thought out.

Someone | 11 hours ago

> but their sudden reintroduction in the Netherlands feels ill thought out.

I don’t think it was a reintroduction, nor was it sudden.

AFAIK, they came back on their own accord, and their return was fairly slowly, after wolves returned to western Germany.

https://wolf.org/wow/europe/netherlands/:

“In a paper published in 2016, “The first proof of the recent presence of Wolves in the Netherlands,” authors wrote:

“In light of the expansion of wolves from the Polish border to the northwest of Germany and the sightings in Denmark, the appearance of the wolf in the Netherlands was no surprise to most experts. In March 2015, this expectation was fulfilled when, after generations without resident wolves, a single wolf wandered through the Dutch provinces of Drenthe and Groningen in broad daylight. From 7 to 10 March 2015, the Netherlands witnessed the comeback of an iconic species.”

Since 2019, the country has once again become home to its first pack of wolves with young pups after 150 years. Genetic sampling revealed the Netherlands wolves came from an Alpine population and Central European populations (i.e. Germany)“

Pair the sheep and goat herds with one or two decent sheepdogs - Kangals/Karabaş, Ovcharka (in Slavic languages, ovce means sheep, so their purpose is literally their name) or similar large breeds. That is usually enough to drive off wolves to feed off of deer instead that are a true scourge for forestry when the hunters don't keep up.

The wolves seemingly made it back into the Netherlands on their own:

  In a paper published in 2016, “The first proof of the recent presence of Wolves in the Netherlands,” authors wrote:

Wolf numbers are now reportedly at 131 split across roughly 14 packs (April 2026): https://nltimes.nl/2026/04/11/dutch-wolf-population-growing-...

I have zero insight into why Wageningen University & Research (WUR) in the Netherlands concluded in a study that "the Netherlands are legally required to contribute between 23 and 56 wolf packs" (Lost in translation? - perhaps "can support and shouldn't cull below these numbers" ?)

~ https://www.wur.nl/en/news/ecological-and-legal-framework-wo...

Phemist | 12 hours ago

Dutch version of the WUR page says basically the same thing: "Uit het onderzoeksrapport blijkt dat Nederland juridisch gezien een bijdrage aan de wolvenpopulatie moet leveren van 23 tot 56 roedels. " -> the study concludes that the Netherlands has to contribute to the wolf population from 23 to 56 wolf packs.

Reading further:

https://edepot.wur.nl/690748

It seems that this is part of a european "habitats directive" for managing biodiversity within Europe. This directive (according to the above paper) determined there need to be around 500 wolf packs across Europe to keep wolves at a stable level without too much inbreeding. The Netherlands was found to be able to "contribute" 23 to 56 wolf packs in this sense.

Razengan | 12 hours ago

If those were wild sheep, and the wolves came there on their own like the other comments said, isn't that just nature working as intended?

If those were private sheep, shouldn't they be better guarded?

defrost | 12 hours ago

As a livestock owner not in the Netherlands, yes, people should guard their stock.

That's somewhat distinct from going further beyond their boundaries to wipe out threats not directly on their land.

KaiserPro | 11 hours ago

I think the issue is that for a number of generations parts of europe have not been used to apex predators.

In the UK we've not had wolves for >200 years. Which means techniques for dealing with them have been lost, and more importantly didn't evolve with land use change. hearders used to carry weapons, and guard dogs. some places had fainting goats.

I'm not sure how wolves would work in the netherlands, as the parts that I know are all way west of the ijssel. I don't imagine that wolves are fen/polder dwellers, but I might be wrong. Again looking at the norfolk/cambridge fens there are plenty of folklore tales https://www.norfolkfolkloresociety.co.uk/post/the-spectral-w...

Razengan | 11 hours ago

The UK is just sickening for exterminating so many animal species, and now they're after badgers. What the hell is wrong with that country? Who will scold Toad out of his motorcar addiction??

defrost | 11 hours ago

You appear to be equating guarding stock with exterminating species, and further making a sweeping generalisation about all(?) landholders "going after badgers".

When I answered your question above I was pretty specific in the wording, perhaps you're letting some personal PoV read to much into what others are saying.

The badgers issue is unrelated to the wolves, but it’s the same thing of humans being cunts to animals

It's not just the Netherlands, this is happening in Italy as well. Part of it is just the natural consequence of people having abandoned the countryside and mountains for the cities. But we certainly forgot what it means to not be the only apex predator around- we used to be able to roam around without a fear in the world like we owned the fucking place (we did). It's nice to have a wild ecosystem around but we probably forgot what it means to have around beings that are... unaligned with us.

Why are sheep so important to protect versus wolves? They are both animals that existed in nature and can continue to exist in nature.

Why should we be morally inclined to try and "save" sheep at the expense of wolves. Sheep and goats and deer survived throughout history without the help of humans they will continue to exist, with or without the help of humans against wolves.

mannycalavera42 | 11 hours ago

sorry but I think you are not considering history and data here... sheep and goats were selectively bred by humans and often cannot survive without us. Modern (domestic) sheep and goats are veeeery different from their wild ancestors (e.g. traits vital for wild survival got removed). The idea that "they survived history, they will survive forever" is a classic logical fallacy. Many species survived for millions of years right up until rapid environmental shifts/new pressures drove them to extinction (e.g. see the pyrenean ibex). Moreso: modern habitats have little resemblance to historical ones. Wild deer/goats/sheeps evolved in vast, connected ecosystems! With human development (highways/agricultural fencing/climate change) today we have severely fragmented habitats: natural migration routes are no longer there. So a lot of these "survived thorughtout history" animals can get easily squared / hunted down

you have to go back more than 100 years, but fair.

In those 100 years the rest of the environment changed, it's a bit of an experiment right to reintroduce it without having contingency plan if things go wrong, because shooting them if they are too aggressive is not allowed, unless they're marked as 'problem wolf'.

I went through a phase where I was recommended a bunch of boar traps on youtube. There is one called "the pig brig" that is like a soft net where they can go in under the net but not get out. It's sad they all get trapped and then shot but sounds like necessary because they destroy land and native species. It's sad watching the pigs panic and run around trying to escape once they realize they are trapped :(

Yes, very much so here in and around Berlin. No garden is safe, and neither is your trash unless you lock it in somewhere. They no longer mind human presence at all, which was not the case 20 years ago (they used to be very shy), and they have become really smart, too, and have opened or unhinged our fence gate several times.

Across European Plain entire native wildlife down to pigeons and rats had been killed and/or consumed at some point because of wars and famines. Entire current wildlife has been reintroduced.

asanineassasin | 12 hours ago

Introducing the concept of the "scratchpost" to nature lovers. If im small and hunted, why does it help me to know predators nearby who do not hunt me- and to take predators chasing me, to them, so they get eaten? Because survival means, if i have a scratchpost, i can get rid of them.

So what is a village of humans- not allowed to hunt me near houses, with driving cars- other then a predator scratchpost. Bonuspoints if the disney-hystrics install dart guns to sedate the predators.

Also look at those boars and deer. They are massive. Are you really sure, a creature whose culture changes on a yearly basis, will not try to attack a weak human, compared to a wild boar, when hunger bites in the winter?

We should also definitely reintroduce lions to Southern Europe ! We know for sure they were roaming in Greece (Herodote talks about them during wars against Persia, Herakles had to kill Nemee lion according to the legend, etc.), and that they were hunted, most certainly to extinction.

I saw something like this in the City I live in. There were Pigeons everywhere. one day ages ago I was riding my bicycle to college and I saw a hawk fly down to a group of Pigeons hanging around on the ground and grab one. The Pigeons looked surprised and did not know what to do. That was over 40 years ago when Hawks started repopulating the area.

Not long afterwards, all Pigeons started hiding and you do not see many just hanging around. One favorite place is under bridges. Shows animals will learn real fast to avoid threats :)

I had a bird feeder out in my backyard one winter and had a hawk show up looking for lunch. A squirrel that was hanging around scrounging on the ground ran and hid under a cedar tree. It was interesting because for 99% of other threats, their instinct is to get off ground level and up a tree or telephone pole to safety. Apparently they're smart enough to know not to do that with birds of prey.

Researching this and imagining what the Romans saw in their campaigns up north, and also Asterix comics, I found this tidbit about adaptation in general: "Wolves generally follow Bergmann's rule, a biological principle stating that populations of the same species living in colder, higher-latitude environments tend to be larger than those closer to the equator."
