Also they have trouble overcoming man-made and naturally occurring obstacles, like roads or swamps. However, this species has a low ability of dispersal, and since they are mainly introduced into woody forests or urban areas with greenery, they have less potential to be naturally dispersed to other regions. Tamias sibiricus is able to survive in various environmental conditions, anywhere from 29°N to 69°N and -65 ☌ to 30 ☌. In Europe, the introduced populations usually live in deciduous forests, mixed deciduous and coniferous forests, or urban areas with greenery. They are usually found in coniferous forests, stony areas within forests and mountains, habitats filled with shrub, along waterways or roads, or other small patches of agricultural land. The Siberian chipmunk can survive in a variety of habitats and conditions. While thousands of animals were introduced to new environments, their naturally slow spreading, 200 to 250 meters per year, prevented them from rapidly moving to areas beyond Europe. Other Siberian chipmunks escaped from captivity and inhabited the forested areas of Europe. Owners released these animals because they no longer wanted them as pets, or the owners purposefully freed the chipmunks to live naturally in the wild. By the 1970s, the Siberian chipmunk inhabited suburban forests and urban parks in Belgium, France, Switzerland, Germany, Italy, the Netherlands, and Austria.
Human introduction is a major risk for the spread of this species into other forests and areas. Between 19, South Korea exported more than 200,000 individuals to Europe.
During the 1960s, South Korea began to export these animals to Europe as a part of the pet trade. Siberian chipmunks were found only in their native range of Eastern Asia until the 1960s, when this species was introduced to European countries.
