Habitat shift is another strategy used by plants to evade climate change. The term evade may be more relevant here owing to the fact that with habitat shift a plant can translocate to a different area. Typically with habitat shift a plant will move to a different habitat, as implied by the name. An example of this can be seen in the California Valley Oak (Quercus lobata), which is very sensitive to climate change. This species when exposed to elevated temperatures shifts itself northward and tends to move from a largely terrestrial habitat to the edges of water sources. This is not foolproof because their new habitat presents a dead end for the species. The rapidly increasing climate will eventually kill the Quercus lobata (McLaughlin and Zavaleta 2012). These shifts can be even more drastic. For example, one paper used computer models to observe climate change in Germany. Based off of predicted models the paper inferred that many species would begin shifting to the Iberian Peninsula in order to avoid climate change (Bergmann et al. 2009). Again, this shift could later become an issue as with the Quercus lobata because of the dead end scenario. The dead end scenario is not the only limitation associated with habitat shifts. Other limitations include the plants intrinsic abilities to move these distances. It will be discussed further a little later in the paper, but if a plant has poor dispersal mechanisms than it wont be able to escape climate change. Furthermore, if a
