It's Important To Remember That Most 'invasive Species' Did Not Change The Region And Habitat To Which

it's important to remember that most 'invasive species' did not change the region and habitat to which they have adapted by their own accord; stowaways on cargo vessels, changed migration patterns due to human settlements or a changing climate; animals formerly used for furs or other animal products being released after those goods were no longer in demand... these animals are displaced. it's very sad because often the best solution is population control.

we made the problem and the best solution feels pretty ugly, but the alternative is often ecologically much worse.

Northumberland and Cumbria red squirrel groups say greys freed by public

The groups protect red squirrels by trapping greys but say some are released and equipment damaged.

Not only do we have the rich elite releasing millions of non-native birds for sport shooting, and shooters and farmers campaigning against efforts to re-wild parts of the UK, we also have animal rights groups sabotaging conservation efforts.

Grey squirrels are highly invasive in the UK. They spread disease, outcompete the native red squirrel, and also predate native bird nests and damage trees. Culling them is vital to helping to restore ecosystems and threatened native wildlife. Yet there are groups of ARAs dedicated to saving these invasive squirrels. UK wildlife just can't win.

This is how bad the situation is btw:

An illustration of Incamys, an extinct relative of modern chinchillas. It's a chunky fluffy rodent with bristly whiskers, large eyes, rounded ears, and a long bushy tail. It's depicted as colored grey-brown with a paler underside.

Incamys bolivianus was a caviomorph rodent representing an early member of the chinchillid family, with its closest modern relatives being chinchillas and viscachas.

Living in what is now Bolivia and Argentina during the late Oligocene about 27 million years ago, it inhabited an arid open grassland at a time when the area's climate had drastically cooled due to the formation of the Antarctic Circumpolar Current.

It's estimated to have been similar in size to a large modern chinchilla – weighing around 700g (~1lb 8oz) and measuring about 25-30cm long not including the tail (~10-12").

An endocast of the shape of its brain from a near-complete fossil skull shows that it had a well-developed sense of hearing, particularly in vocalization processing, suggesting it may have been a social animal living in groups communicating with complex calls similar to modern chinchillids. It was probably a ground-dweller less agile than its modern relatives, but still capable of fast movements.
