The Tundra straddles the border between Forodwaith and the rest of Middle-earth. It is similar to the ice plains biome in vanilla Minecraft, except Gundabad Orcs, wolves and Wargs spawn at night, along with ruined houses. The precipitation in this biome is snow instead of rain, but, unlike Forodwaith, the player won't take frost damage in this biome.
The Taiga is the densely forested south of the Tundra, forming the border between the northern Tundra and the more temperate lands of Middle-earth. Spruce, fir, and pine trees dominate the vast woods of the Taiga. These woods are home to much more large animal species than the northern Tundra plains.
As the Tundra and Taiga are relatively different, lists of variants for each is given below.
Tundra
Standard - Normal Tundra biome.
Light forest - Lightly forested lands.
Steppe - A flat landscape of grassy plains.
Barren steppe - These barren plains stretch over vast area's and have even less vegetation.
Hills - A hilly landscape with a higher average elevation.
Dead forests of oak, spruce and mixed oak and spruce - Lands covered in forests whose glory is passing away. The forests' density is comparable to the light forest variant, but there are many stems of dead, leafless trees. This variant is very helpful for acquiring large quantities of wood, as the dead trees provide a lot of easy accessible lumber.
Taiga
The Taiga is a forest biome and has the following variants:
Standard - Normal Taiga biome, which is relatively densely forested.
Flowers - The fields and the undergrowth of tree clusters teem with flowers in this biome. Flowery vegetation from both vanilla minecraft (poppies, dandelions) and the LotR Mod (thistles and wheat grass) is abundantly present here.
Hills - A hilly landscape with a higher average elevation.
Clearing - Clearings in the surrounding forest without any trees and a typically flat surface.
Light Forest - Lightly forested lands.
Dead spruce forest - Lands covered in forests whose glory is passing away. The forests' density is comparable to the light forest variant, but there are many stems of dead, leafless trees.
The weather is rather cold and rough in the Tundra. Therefore perhaps this rune fits here: The anglo-saxon hægl-rune ᚻ (= letter H) means "hail" (ice pellets). Tolkien used those ᚱᚢᚾᛖᛋ for some texts in the initial drafts of "The Lord of the Rings", later on, he replaced them by cirth runes.
“
ᚻ Hail is the whitest of grain; it is whirled from the vault of heaven and is tossed about by gusts of wind and then it melts into water.
