Types of Forest 1 Chart

Spectrum Chart - 441 : Types of Forest 1

1. Temperate Coniferous Forest - Temperate coniferous forest is a terrestrial biome found in temperate regions of the world with warm summers and cool winters and adequate rainfall to sustain a forest. These forests can be found in the United States, Canada, Europe and Asia. Many species of tree inhabit these forests including cedar, cypress, Douglas fir, fir, juniper, pine, podocarpus, spruce, redwood and yew. The understory also contains a wide variety of herbaceous and shrub species.

2. Subalpine Coniferous Forest - Subalpine conifer forests is a temperate coniferous forests eco region. These forests are typically found on steep, rocky, north-facing slopes. This eco region is home to several species of mammals.

3. Freshwater Swamp Forest - Freshwater swamp forests are forests which are inundated with freshwater, either permanently or seasonally. They normally occur along the lower reaches of rivers and around freshwater lakes. Freshwater swamp forests are found in a range of climate zones, from boreal through temperate and subtropical to tropical.

4. Lowland Equatorial Evergreen Rainforest - Lowland equatorial evergreen rainforests are forests which receive high rainfall with more than 2000 mm or 80 inches of rains annually throughout the year. These forests occur in a belt around the equator, with the largest areas in the Amazon basin of South America, the Congo basin of central Africa and parts of the Malay Archipelago.

5. Secondary Forest (Second – Growth Forest) – A secondary forest (second-growth forest) is a forest or woodland area which has re-grown after a major disturbance such as fire, insect infestation, timber harvest or wind throw, until a long enough period has passed so that the effects of the disturbance are no longer evident. Secondary forests tend to have trees closer spaced than primary forests and contain less undergrowth than primary forests.

6. Mangrove Forest – Mangroves are shrubs or small trees that grow in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are salt tolerant trees, also called halophytes and are adapted to life in harsh coastal conditions. They contain a complex salt filtration system and complex root system to cope with salt water immersion and wave action. They are adapted to the low oxygen (anoxic) conditions of waterlogged mud.

7. Boreal Forest or Taiga Forest - Taiga also known as boreal forest is a biome characterised by coniferous forests consisting mostly of pines, spruces and larches. The taiga is the world's largest biome apart from the oceans. In North America it covers most of inland Canada and Alaska as well as parts of the extreme northern continental United States.

8. Peat Swamp Forest - Peat swamp forests are forest wetlands in tropical and subtropical areas. They have poor drainage and waterlogged soil prevents dead leaves and wood from fully decomposing. Over time, this creates a thick layer of acidic peat. Peat swamp forests are usually surrounded by lowland rain forests on better-drained soils and by brackish or salt-water mangrove forests near the coast. Peat swamp forests are home to thousands of animals and plants, including many rare and critically endangered species such as the orangutan and Sumatran tiger, whose habitats are threatened by peat land deforestation.
