There isn't a single biome that is exclusively located between 30 and 60 degrees latitude. This range encompasses a variety of biomes, depending on other factors like precipitation and elevation.

Here are some biomes you might find in that latitude range:

* Temperate Deciduous Forests: Found in areas with moderate rainfall and distinct seasons, common in Eastern North America, Europe, and East Asia.

* Temperate Grasslands: Occur in areas with less rainfall than deciduous forests, often characterized by hot summers and cold winters. Examples include the Great Plains of North America and the Eurasian Steppes.

* Temperate Rainforests: Found in areas with high rainfall and mild temperatures, often on the west coasts of continents. Examples include the Pacific Northwest of the US and parts of Chile.

* Mediterranean Woodlands and Shrublands: Located in regions with warm, dry summers and cool, wet winters. Found around the Mediterranean Sea, California, and parts of Australia.

* Boreal Forests (Taiga): Occur in colder regions with long winters and short summers, typically found in the northern latitudes.

The specific biome present at a given latitude will depend on the specific location and its climate.
