===Hemiboreal (Boreonemoral)===
{{Unsourced section|date=December 2023}}[[File:Bygdøy Oslo.jpg|thumb|[[Bygdøy]] October 2007; the hemiboreal lowland near [[Oslofjord]] has the highest diversity due to being closest to the migration route from the south.]]

The [[hemiboreal]] zone covers a total of 7% of the land area in Norway, including 80% of [[Østfold]] and [[Vestfold]]. This vegetation represents a mix of nemoral and boreal plant species, and belongs to the [[Palearctic]], [[Sarmatic mixed forests]] [[terrestrial ecoregion]] (PA0436). The nemoral species tend to predominate on slopes facing southwest and with good soil, while the boreal species predominate on slopes facing north and with waterlogged soil. In some areas, other factors overrule this, such as where the bedrock gives little nutrient, where oak and the boreal [[Scots pine|pine]] often share predominance. The boreonemoral zone follows the coast from [[Oslofjord]] north to [[Ålesund (town)|Ålesund]], becoming discontinuous north of [[Sunnmøre]]. In Oslo, this zone reaches to an elevation of {{convert|200|m}} above sea level. It also reaches into some of the lower valleys and just reaches the lowland around [[Mjøsa]], but not as far north as [[Lillehammer (town)|Lillehammer]]. In the valleys of the south, this vegetation might exist up to {{convert|300–400|m}} above sea level. The zone follows the lowland of the west coast and into the largest fjords, reaching an elevation of {{convert|150|m}} there, even to {{convert|300|m}} in some sheltered fjords and valleys in [[Nordmøre]], with nutrient-rich soil. The northernmost locations in the world are several areas along the [[Trondheimsfjord]], such as [[Frosta Municipality]], with the northernmost location being [[Byahalla]], in [[Steinkjer Municipality]]. Some nemoral species in this zone are [[English oak]], [[sessile oak]], [[Fraxinus excelsior|European ash]], [[Ulmus glabra|elm]], [[Norway maple]], [[Common hazel|hazel]], [[Alnus glutinosa|black alder]], [[Small-leaved lime|lime]], [[Common yew|yew]], [[holly]] (southwest coast), [[Prunus avium|wild cherry]], [[Allium ursinum|ramsons]], [[Fagus sylvatica|beech]] (a late arrival only common in [[Vestfold]]), and [[Primula vulgaris|primrose]]. Typical boreal species are [[Norway spruce]], pine, [[downy birch]], grey alder, [[aspen]], [[rowan]], [[Anemone nemorosa|wood anemone]], and ''[[Viola riviniana]]''.
