THE CASE OF THE MISPLACED NUTRIA

This article left me puzzled. Why on earth would anyone want to introduce nutria? California doesn’t even allow hunting?

Giant rodent that could devastate California wetlands was ‘deliberately’ reintroduced to population, experts fear

A destructive, invasive giant rodent may have been deliberately reintroduced in California, posing a serious threat to the state’s fragile wetlands, wildlife officials said.

The species, known as nutria, is a large semi-aquatic rodent native to South America that can weigh up to 20 pounds and consume vast amounts of vegetation.

A first-of-its-kind genomic study found that nutria discovered in Merced County in 2017 are genetically linked to a population in central Oregon – which suggests the invasive rodents were illegally reintroduced to California by humans decades after being eradicated in the 1970s, the California Department of Fish and Wildlife said Tuesday.

So a nutria in Merced has the same DNA as a nutria in Oregon and that means they were deliberately introduced? Um how did they get to Oregon in the first place?

Are their Nutria in Nevada or Arizona? Did you test their DNA?you know they swim right?

“Given where nutria were rediscovered in California, it is nearly impossible that they could have migrated there on their own,” Michael Buchalski, Fish and Wildlife’s wildlife genetics research lead, told

The motive behind the suspected reintroduction remains unclear, officials say. Some believe the nutria may have been released as a misguided attempt at vegetation control, while others suspect possible environmental sabotage, SFGate reports.

You know how it is. Some crazy hippie wants to create havoc on the area and releases a rodent which looks a lot like the other rodent Merced kills all the time. It happens so often!]

“Someone may have thought they could be an effective natural way to manage aquatic vegetation on their private property,” Buchalski said. “Also, some people just really like nutria…Or it could have been malicious in hopes that they would cause environmental damage. It’s hard to know.”

Who? Tell me who?

Regardless of intent, the consequences could be severe. Nutria are known for aggressively feeding on aquatic plants, often consuming up to a quarter of their body weight daily, which can devastate marsh ecosystems and destroy habitats for native species. Their burrowing behavior also weakens levees and irrigation systems, increasing the risk of flooding and infrastructure failure.

Since 2017, the state has removed thousands of nutria and spends about $5 million each year to control the population, while also setting up inspection stations at key entry points as a “first line of defense” against further introductions.

You know I went for a boat ride in Louisiana where the good old boys told us that they were called Nutria by the government so that people would think they were NUTRITIOUS and eat them.

Also Nutria is spanish for otter.

Also Wikipedia says that Nutria were purpose introduced from south america for their fur after by the Tobasco family.

In Europe the word for Nutria is Coypu. No telling who introduced them there.

Let’s just say when it comes to this animal’s background I’m a little SKEPTICAL.

Despite those efforts, officials warn that preventing additional human-assisted spread remains critical. The introduction and transport of nutria into California is illegal, and authorities stress that continued vigilance is necessary to protect the state’s ecosystems.

“The results of this study additionally will benefit future national and global genetic research on nutria,” Buchalski said in a statement.

Okay. If you says so Michael.

In France and more broadly across Europe, coypu were introduced in the late 1800s and again in the 1920s, at a time when beavers had disappeared but there was still demand for fur, particularly for the hat-making industry. But the economic crisis of the 1930s sounded the death knell for these farms, from which quite a few coypu had already escaped. Bankrupt farmers also had no qualms about opening their cages wide and releasing the animals into the wild. Western and central France, as well as the Rhône Valley (where I live), are heavily colonized and pose a problem. I wish you the best of luck.

That’s really interesting. How is nutria for fur anyway? I was told it was worthless?
