How do grasslands survive the extreme winters?

Answer:
Weathering the Weather
In temperate grasslands, grasses and other plants must survive cold frozen winters and hot, dry summer droughts. ... During a cold winter, grasses become dormant, which means that they don't grow new leaves, seeds or roots until spring comes with warmer temperatures and fresh rain.
It is either tough enough to survive the winter temperatures of your area, like in Ireland, or even the lowest parts of Switzerland nowadays. It stays green pretty much all year. Another way of survival is snowcover. If snow covers grass, it protects it against really cold temperatures, because the snow acts as insulation, like an igloo does. Another way of survival for grass is that it dies back to the ground after first frost and only the deep roots will survive. In spring, moisture provided, the roots will send out new fresh shoots. So called bermuda grass does this. A lawn from it will be brown in winter or when dry, but will get green again when you water it in spring.
A last method for grasses to survive winter (or drought) is - not to! They only survive as seeds and will grow back as soon a conditions warrant. Such grass will not form lawns. There are literally hundreds of such grass species in the Chihuahuan Desert. You will see only a few bunches of them and not every year.
