Natural grassland tend to be developed in dry areas with high evaporation - it's listed as steppe (and scrub, depending on how you define it) in the Holdridge life zones system. Basically, trees need a certain amount of water to grow, so when the land is dry enough, trees will be mostly absent, resulting in grasses taking over as the dominant plant. Of course, if it's even drier (and without other sources of water like oasis or river), xenic grass and scrubs will take over, resulting in the hot Mediterranean and semi-arid biomes that dominate many of the (somewhat) more hospitable desert borders.
In /who/'s case, you might have a better chance of finding them further inland, since those places tend to be drier - which also matches where many of the bigger grasslands on Earth (steppes and prairie) are found. Of course, many modern RL grasslands are actually not natural per see, but a result of human deforestation - the British Isles, for example, has been in the process of deforestation since as early as the Romans' first arrival. In a way, the spread of grassland is something human plays a major role in - after all, most of our farmlands are used to grow specific kinds of grass for food - either for ourselves or our food.
