I'd eat squirrel stew and would never argue that people shouldn't hunt for food.
I'm not convinced that we are ever going to kill all the grey squirrels and somehow the reds are going to make a comeback.
I like grey squirrels just fine and I am unbothered by the fact that they out compete the reds.
But I'm no biologist and have just read one article. What I'm more interested in is the thinly disguised xenophobia and glee in shooting the "foreigner squirrel "
Competition within an established ecosystem can create problems other than just undermining the immediate competitive species, but it can also create benefits if you're lucky. Between grays and pigeons, urbanizing raptors have less competition for lunch options, which can help bring low population numbers back.
Culling alone rarely works for any species that reproduces as easily and often as anything in the Rodentia taxon. Conservationists are more likely to have greater success combating Squirrel parapoxvirus by finding a way to wipe out the virus so that reds don't get it in the first place, and propping competition with more aggro grays by offsetting reds mortality numbers with captive breed-for-release and strategic food availability.
Need to see if I can find any studies on food availability and behavior with UK grays and reds. With the grays I raise as rescue/rehabs here, I notice that the more food and dray options I make available, the less fighting and aggression displays I see. That's not unusual for a lot of animals; when there's food and resource security, they have less reason to waste energy on fighting for primary access to them. I can keep opossum and raccoons from stealing the squirrel food by putting up a barrier with an entrance too small for them that will allow the squirrels. It'd be a much trickier difference in sizes, but I'd like to try the same thing with reds. One more project to add to my UK species Bucket List ;0)
