This ecoregion features a predominantly subarctic climate (Köppen Dfc) with cold winters and cool, foggy summers. The area around Mistaken Point features a milder subpolar oceanic climate (Köppen Cfc) with relatively mild winters and cool summers. Precipitation occurs year-round, with a mean annual precipitation between 1200 and 1500 mm.[2]
This ecoregion supports dense carpets of moss and fruticose lichen, along with low-growing ericaceous shrubs and wildflowers. Small communities of dwarf balsam fir can be found in some upland regions.[2]
