The South Boreal zone (SB) is dominated by boreal species, especially [[Norway spruce]], and covers a total of 12% of the total land area. The SB is the only boreal zone with a few scattered—but well-developed—warmth-demanding broadleaf deciduous trees, such as [[European ash]] and [[oak]]. Several species in this zone need fairly warm summers (SB has 3–4 months with a mean 24-hr temperature of at least {{convert|10|C}}), and thus are very rare in the middle boreal zone. Some of the species not found further north are black alder, [[Humulus lupulus|hop]], [[Origanum vulgare|oregano]], and [[Viburnum opulus|guelder rose]]. This zone is found above the hemiboreal zone, up to {{convert|450|m}} amsl in [[Østlandet]] and {{convert|500|m}} in the most southern valleys. In the eastern valleys it reaches several hundred kilometers into Gudbrandsdal and Østerdal, and up to [[Lom Municipality]] and [[Skjåk Municipality]], in [[Ottadalen]]. Along the southwestern coast, the zone reaches an elevation of {{convert|400|m}} at the head of large fjords (such as in Lærdal), and about {{convert|300|m}} nearer to the coast. Norway spruce is lacking in [[Vestlandet]] ([[Voss Municipality]] is an exception). North of Ålesund, SB vegetation predominates in the lowland down to sea level, including islands such as [[Hitra (island)|Hitra]]. Most of the lowland in Trøndelag below {{convert|180|m}} elevation is SB, up to {{convert|300|m}} above sea level in inland valleys such as [[Gauldalen]] and [[Verdalen]], and up to {{convert|100|m}} in [[Namdalen]]. The coastal areas and some fjord areas further north—such as [[Nærøysund Municipality]] and [[Brønnøy Municipality]], and the best locations along the [[Helgeland]] coast—is SB north to the mouth of [[Ranfjord]], while inland areas north of [[Grong Municipality]] are dominated by Middle Boreal zone vegetation in the lowland. There are small isolated areas with SB vegetation further north, as in [[Bodø Municipality]] and [[Fauske Municipality]], the most northern location being a narrow strip along the northern shore of [[Ofotfjord]]; and the endemic Nordland-[[whitebeam]] only grows in [[Bindal Municipality]].<ref>{{cite web |url=http://www.miljostatus.no/nordland/tema/naturomrader/naturvern/verneomradene_i_nordland/verneomrader/reppen_naturreservat.htm |title=Reppen nature reserve |website=miljostatus.no |access-date=21 December 2006 |archive-url=https://web.archive.org/web/20090319000018/http://www.miljostatus.no/nordland/tema/naturomrader/naturvern/verneomradene_i_nordland/verneomrader/reppen_naturreservat.htm |archive-date=19 March 2009 |url-status=dead }}</ref> Agriculture in Norway, including [[grain]] cultivation, takes place mostly in the hemiboreal and SB zones.
