Examples of boreal forest in the following topics:
-
-
- This benefits evergreen trees, which grow faster than deciduous trees in the boreal forest.
- The net primary productivity of boreal forests is lower than that of temperate forests and tropical wet forests.
- Boreal forests lack the pronounced elements of the layered forest structure seen in tropical wet forests.
- The structure of a boreal forest is often only a tree layer and a ground layer .
- As in the boreal forests, there is little evaporation due to the cold temperatures.
-
- Although angiosperms (flowering plants) are the major form of plant life in most biomes, gymnosperms still dominate some ecosystems, such as the taiga (boreal forests) and the alpine forests at higher mountain elevations because of their adaptation to cold and dry growth conditions .
- This boreal forest (taiga) has low-lying plants and conifer trees, as these plants are better suited to the colder, dryer conditions.
-
- At about 30 degrees north, these forests would give way to deserts, which are characterized by low precipitation.
- Eventually, grasslands are replaced by deciduous temperate forests.
- These deciduous forests give way to the boreal forests found in the subarctic, the area south of the Arctic Circle.
- The forest gardenia (Gardenia brighamii), for instance, is endemic to Hawaii; only an estimated 15–20 trees are thought to exist .
- Listed as federally endangered, the forest gardenia is a small tree with distinctive flowers.
-
- Prairies once spanned central North America from the boreal forest in northern Canada down into Mexico.
-
- The neighboring island of Borneo, home to the other sub-species of orangutan, has lost a similar area of forest, and forest loss continues in protected areas.
- A five-year estimate of global forest cover loss for the years 2000–2005 was 3.1 percent.
- In temperate and boreal regions, forest area is gradually increasing (with the exception of Siberia), but deforestation in the tropics is of major concern.
- Long-lived and healthy wetlands and forests are examples of sustainable biological systems.
- (a) One sub-species of orangutan is found only in the rain forests of Borneo, while the other sub-species of orangutan is found only in the rain forests of Sumatra.

-
- Temperate forests are characterized by fluctuating seasonal temperatures and constant-but-moderate rainfall.
- Because of the dormant period, the net primary productivity of temperate forests is less than that of tropical wet forests.
- In addition, temperate forests show less diversity of tree species than do tropical wet forest biomes.
- The trees of the temperate forests leaf out and shade much of the ground; however, this biome is more open than tropical wet forests because trees in the temperate forests do not grow as tall as the trees in tropical wet forests.
- The soils of the temperate forests are rich in inorganic and organic nutrients due to the thick layer of leaf litter on forest floors.
-
- Compared to other forest biomes, tropical wet forests have little variation in seasonal temperatures.
- Tropical wet forests have more species of trees than any other biome.
- Epiphytes are found throughout tropical wet forest biomes.
- For this reason, forest trees do not grow as well as they do in the tropical wet forest or other forest biomes.
- Tropical wet forests, such as the forests of Madre de Dios near the Amazon River in Peru, have high species diversity.
-
- A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire .
- Eventually, over 150 years, the forest will reach its equilibrium point where species composition is no longer changing and resembles the community before the fire.
- Secondary succession is shown in an oak and hickory forest after a forest fire.
