A climate region that is semiarid with short grasses and low brushes is typically called a steppe or a prairie.

Here's a breakdown:

* Steppe: This term is more common in Eurasia and refers to a vast, treeless grassland with semiarid conditions. It often features short grasses and low shrubs, with a dry climate and seasonal rainfall.

* Prairie: This term is more common in North America and also refers to a treeless grassland, but it can have a slightly wetter climate than a steppe. It often features taller grasses and a wider variety of wildflowers.

While both terms describe similar ecosystems, they have different geographic origins and can sometimes have subtle differences in vegetation and climate.
