Bog vs. forest
The interface between bog and forest is a struggle for territory between two different types of vegetation. Crawford et al. (pp. 213-216) examine the climatic history of northern Europe over the past century and its consequences for the position of the treeline. Contrary to some predictions, they suggest that instead of the forest advancing northwards with global warming there are areas where the treeline may be forced southwards due to increased bog growth.
