By contrast, data from certain temperate coniferous forests yield higher biomass and necromass estimates and detritus to biomass ratios than found in this study. Both terms are used to describe the entire circumpolar coniferous forest with its many lakes, bogs, and rivers. In the northern U.S., timberline decreases in altitude, as do the various accompanying vegetational zones. 4.

In comparison with forests worldwide, the input rate of coarse woody debris in the Great Smoky Mountains study forest is moderate (Busing, 2005). The biome of deciduous forests is such that they dont have a dense canopy. Other land biomes of the world include: Temperate forests cover most of the U.S. and Europe and occupy a large portion of Asia. The needles are dark colored, which is also a plus for the conifers. Both coniferous and broad-leaved species are present. The present study is based on the examination of vegetation description, disturbance factors and distribution of tree and understorey species of moist temperate conifer forests of southern . A coniferous forest biome is chiefly made up of cone-bearing or coniferous trees, for example, pines, fir, hemlocks, spruces, cedars, cypresses, redwoods, yews, Douglass firs, larches, and kauris. As with most rainforests, temperate rainforests are evergreen and contain a diverse variety of fauna and flora. Jaguars live in rainforests and cloud forests and they use the dense foliage for camouflage. Tropical, temperate, and boreal forests around the world play an important role in the earths ecosystem. Mosses, liverworts, and lichens cover the forest floor. The thick bark, which affords protection against insects, pathogens, and fire, is thought to contribute to the great longevity (1,000-2,000 years) of individuals. A forest is a type of ecosystem in which there is high density of trees occupying a relatively large area of land. This is not to mention the thousands of insects that inhabit deciduous forests around the world. These forests are richest and most distinctive in central China and eastern North America, with some other globally distinctive ecoregions in the Caucasus, the .

Brown bears (Ursus arctos) are found in the boreal forests and temperate forests of North America and some parts of Eurasia. The northern Eurasian coniferous forest is called the taiga or the boreal forest. These coniferous tree types are softwoods, which means they have the ability to get by in cold temperatures and acidic soils. The understory also contains a wide variety of herbaceous and shrub species. Because the forest canopy is so dense and the soil quality is poor, very little vegetation grows on the forest floor (understory). How many land biomes are there in the world?

Pure stands of incense cedar (Libocedrus decurrens) dominate the richest sites in the lower sections of the zone. New and higher roots are produced in reaction to continued deposition of alluvial material at the bases of the tall trunks, which often surpass 250 feet in height. Montane forests are found in mountainous regions in the tropics. Lichens help to recycle plant leaves, thus generating the fertile soil in this biome. Tropical rainforests are located near the equator and have a temperature that varies from 20 to 30 C (68 to 86 F) during the year.

Rain forests grow a startling variety of fungi on trees . coniferous forest, vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in areas that have long winters and moderate to high annual precipitation. Some moist broadleaf deciduous forests encompass areas beside tropical rainforests and it can be difficult to tell them apart. Trees in deciduous forests lose their leaves in winter, providing organic material for the soil. Here clouds usually form at canopy level and the forest environment can be continually misty or foggy.

Similar to tropical rainforests, these forests are also home to a range of tropical birds, large cats, monkeys, and parrots. Amazon, Congo, Sri Lanka lowlands) Tropical Bane (eg. Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions.. Some say there are as few as four and as many as 11 land biomes on the planet. Vegetation data were collected from 48 forest sites . Temperate coniferous forests sustain the highest levels of biomass in any terrestrial ecosystem and are notable for trees of massive proportions in temperate rainforest regions. The temperate cool rainforests occur poleward of the Mediterranean region, 40- 60 N and S latitude, along the western coast of continents under the influence of the westerlies (roaring forties, furious fifties, screaming sixties; latter doesn't hit the southern continents) . These forests are usually adapted to great climatic variations . Coniferous trees are also characterized by a pointed shape. A distinct subtype of the North American coniferous forest is the moist temperate coniferous forest, or coast forest, which is found along the west coast of North America eastward to the Rocky Mountains.
