In cool climates with consistently high rainfall (on more than c. 235 days a year), the ground surface may remain waterlogged for much of the time, providing conditions for the development of bog [[vegetation]]. In these circumstances, bog develops as a layer "blanketing" much of the land, including hilltops and slopes.<ref>{{cite journal |last=van Breeman |first=N. |date=1995 |title=How Sphagnum bogs down {{sic}} other plants |journal=Trends in Ecology and Evolution |volume=10 |issue=7 |pages=270–275|doi=10.1016/0169-5347(95)90007-1 |pmid=21237035 |bibcode=1995TEcoE..10..270V }}</ref> Although a blanket bog is more common on acidic substrates, under some conditions it may also develop on neutral or even [[alkali]]ne ones, if abundant acidic rainwater predominates over the groundwater. A blanket bog can occur in drier or warmer climates, because under those conditions hilltops and sloping ground dry out too often for peat to form – in intermediate climates a blanket bog may be limited to areas which are shaded from direct sunshine. In [[periglacial]] climates a [[patterned vegetation|patterned]] form of blanket bog may occur, known as a [[string bog]]. In Europe, these mostly very thin peat layers without significant surface structures are distributed over the hills and valleys of Ireland, Scotland, England, and Norway. In North America, blanket bogs occur predominantly in Canada east of [[Hudson Bay]]. These bogs are often still under the influence of [[mineral soil]] water (groundwater). Blanket bogs do not occur north of the 65th latitude in the northern hemisphere.<ref name="keddy 2010" />
