Document Summary
Temperate broadleaf forest: temperate broadleaf forest occurs throughout midlatitudes where there is sufficient moisture to support the growth of large trees. Annual precipitation is relatively high at 75 150 cm (30 60 inches) and usually even around the year. Temperature varies seasonally over a wide range, with hot summers and cold winters. In the northern hemisphere, dense stands of deciduous trees, which drop their leaves before winter, are trademarks of temperate forests. Many invertebrates live in the soil and the thick layer of leaf litter that accumulates on the forest floor. Many mammals that inhabit these forests enter a dormant winter state called hibernation, and some bird species migrate to warmer climates. Coniferous forest: coniferous forests in the northern hemisphere. Are dominated by cone-bearing evergreen trees and. Include the northern coniferous forest, or taiga , the largest terrestrial biome on earth: temperate rain forests are found along coastal north america from alaska to oregon and are also coniferous forests.
