Humans have an impact on species migration both through climate change and by changing the landscape.

One of the reasons climate change is such an important topic is that it will affect (and already is affecting) the natural biological systems. Both plants and animals will have to respond to the changing climate. In some cases, this means adapting to higher temperatures. In other cases, the changes may be alterations in the precipitation, length of growing season, availability or resources, or other influences.

While some animals can adapt, others will have to migrate. Obviously migration can be apparent in mobile animals that will move to maintain a more or less similar climate to that to which they are accustomed.
