Evergreen trees are most prevalent in the northerly latitudes of the northern hemisphere, where they are the primary components of the taiga, or boreal, forest and montane forest biomes. Evergreen trees are also found in the southern hemisphere and in pockets centered around the equator. In warmer climates, evergreen species can be dominant elements of tropical and temperate rain forests.Continue Reading
The evergreen forests in the northern hemisphere are overwhelmingly made up of coniferous species, including firs, pines, junipers and spruces. These types of species thrive in environments where summers are short and winters are long and harsh. Conifers don't have leaves, instead, they have waxy, tough needles or scale-like foliage.
In tropical and temperate rain forests, evergreen tree species aren't limited to just conifers. Warm temperatures and ample rainfall, as well as little or no winter season at all, allow other types of species to keep their leaves throughout the year. Angiosperm species located in habitats that experience winter are deciduous, dropping their leaves and going into dormancy to protect themselves from the harmful effects of freezing. Angiosperms in tropical and temperate rain forests, including palms, figs and eucalyptus, don't have these seasonal constraints and keep their leaves all year. Evergreen gymnosperms, such as cycads, are also commonplace in rain forests.Learn more about Botany
The trees in the taiga have thick bark that protects them from low-heat wildfires. Mild fires often burn away sick trees and allow new growth. They also burn the canopy of the trees and allow sunlight to pass and reach the ground.Full Answer >
Moose mainly live in the taiga and tundra biomes. They also live in parts of Alaska, southern Canada, the northern United States, northern Europe and southern Asia.Full Answer >
The main types of soil typically found in the taiga biome are spodosol, histosol and inceptisol, all of which contain very few nutrients. There are also large areas of taiga in North America and Europe that have very little to no soil, due to it being scraped away by glaciers.Full Answer >
The most common types of plants found in temperate grassland biomes are grasses and wildflowers, with trees and large shrubs also being present but very rare. Common types of grasses found in these biomes are ryegrass, wild oats, foxtail, purple needle grass and buffalo grass. Wildflowers, such as, sunflowers, blazing stars, clovers, asters and wild indigo are often very abundant in grassland biomes.Full Answer >
