However, this approach overlooks two important factors that may affect species» responses to climate change:

Sax, who studies amphibian responses to climate change, says, «There are a lot of species you wouldn't normally be concerned about that might be in trouble in the future» because a barrier stands between their current habitat and one they might need to occupy in coming decades.

In other words, even though the species composition may shift in response to changes in the climate, the bog itself can remain largely unaffected.

Although dynamic vegetation models tend to predict an overall expansion of cool forests and woodlands (Shafer et al. 2015), some tree species may actually experience reduced ranges due to geographical obstacles to range expansion in response to climate (Coops and Waring 2001).

Range limits of many plant species are expected to shift considerably in the next decades due to human - mediated climate change, particularly at higher latitudes, but the capacity of trees to migrate in response to these events has been questioned.
