°C in the northernmost part (Bodø 5.5 °C Andenes 4.4 °C). This type of climate corresponds to Köppen type Cfb (Cfc for the northernmost islands). Temperatures and precipitation pattern are comparable to the coast of British Columbia from northern Vancouver Island and north through the Alaska Panhandle to Yakutat and Seward. For the smaller area classified as rainforest, there is at least 200 days/year with measurable precipitation. The minimum annual precipitation given in the sources varies but are generally around 1.400 mm. Some of the wettest areas in this ecoregion get more than 3000 mm annually, such as Brekke (3495 mm) near the mouth of Sognefjord, and even some areas much further north (Lurøy 3066 mm at 115 m ASL). Subregions and species The lack of spruce north of the Arctic circle (Saltfjell) and along the southwestern coast is mainly due to barriers such as fjords and mountain ranges, and planted spruce grows well north of the arctic circle as in Tromsø. The southern limit of the Norway Spruce habitat in Norway is limited by mountains and fjords blocking the way, and also because of winters being too mild for Norway spruce near the outer seaboard along the southwestern coast. Along the southwestern coast and fjords (Vestlandet or Western Norway) is a temperate mixed forest with pine, some yew and deciduous trees (betula pendula, wych elm, linden, oak, aspen, hazel, juniper) in the lowlands and more typical boreal forest at higher altitudes. Several species reach their northernmost extent in this ecoregion (naturally occurrence): Oak to Edøy and Ørland, yew to Molde, holly to Smøla, ash to Frosta, linden to Brønnøy, elm to Beiarn, hazel to Steigen, and pine has its northernmost forests in the world at Stabbursdalen National Park. The botanically richest areas - the coast north to Ålesund and some patches further north along Trondheimsfjord), although less diverse than the Oslofjord area due to migration barriers like fjords and mountains - are considered boreonemoral. Some of the wettest areas in this region, where annual rainfall exceed 2,000 mm or even 3,00 mm, are sometimes considered boreonemoral rainforest. Introduced species Introduced species include the Norway spruce, which has been planted for economic reasons in areas outside the natural range both on the southwestern coast and in the northernmost part of the ecoregion. Sitka spruce has also been planted extensively, especially near the outer seaboard, even north to Vesterålen and Harstad.
