I don't exactly know Noway's climate, but I'd assume Oslo to be a bit more temperate than TO. So cool summers, and cooler (but more stable) winters than ours - with less extremes in each. As well, snowfall and accumulation itself doesn't mean much in terms of an area's temp, and if anything it can actually act as an insulator for grass. And like the comment says above, it's more of a proper ROW with an ample buffer. Here, I'd presume both QQ and MGT to be salted - which I don't think would help any kind of vegetation on the adjacent ROW.
