The reason that mountainous regions can often have a large variety of distinct biomes within a small area is temperature.  A mountainous region will have a wide diversity of temperatures within a small area.  Because of that, it will have a lot of different biomes.

Mountainous regions will have many different temperatures in part because of differences in elevation.  The higher one goes up the side of a mountain, the colder it gets.  So on one slope, you can end up with a bunch of different biomes.

A second factor that would affect temperature is the direction in which the mountain slopes face.  In the Northern Hemisphere, south-facing slopes stay warmer for more of the year than north-facing slopes.  This will allow them to have different biomes.

For these reasons, it is common to have many different biomes within a small mountainous area.

A mountainous region would have varying temperatures in different parts of the regions. The higher the part of the mountain, the colder it is.

Also, the sides of the mountain facing the sun in the time period of the year would be warmer as compared to other parts of the mountain.

Therefore, it is possible to have many different biomes within a small mountainous area.
