Tropical evergreen forests are dense, multi-layered, and harbour many types of plants and animals. These forests are found in the areas receiving heavy rainfall (more than 200 cm annual rainfall). They are very dense. Even the sunlight does not reach the ground. Numerous species of trees are found in these forests.
Evergreen. A silver fir shoot showing three successive years of retained leaves. In botany, an evergreen is a plant which has foliage that remains green and functional throughout the year. [1] This contrasts with deciduous plants, which lose their foliage completely during the winter or dry season.
Originally evergreen trees grew in the landscape. After the fire, the area took at least a year to grow shrubs. Eventually, deciduous trees started to grow instead of evergreens. [25] Secondary succession has been occurring in Shenandoah National Park following the 1995 flood of the Moorman's and Rapidan rivers, which destroyed plant and animal ...
Synonyms. Veitchia Lindley. A spruce is a tree of the genus Picea (/ paɪˈsiː.ə / py-SEE-ə), [1] a genus of about 40 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal (taiga) regions of the Earth. Picea is the sole genus in the subfamily Piceoideae.
It is an evergreen, long-lived, monoecious tree living 1,200–2,200 years or more. [4] This species includes the tallest living trees on Earth, reaching up to 115.9 m (380.1 ft) in height (without the roots) and up to 8.9 m (29 ft) in diameter at breast height. These trees are also among the longest-living trees on Earth.
Fire cycles also tend to be long near the tree line in the subarctic spruce-lichen woodlands. The longest cycles, possibly 300 years, probably occur in the western boreal in floodplain white spruce. [45] Amiro et al. (2001) calculated the mean fire cycle for the period 1980 to 1999 in the Canadian boreal forest (including taiga) at 126 years. [44]
Description. Pinus sylvestris is an evergreen coniferous tree growing up to 35 metres (115 feet) in height [4] and 1 m (3 ft 3 in) in trunk diameter when mature, [5] exceptionally over 45 m (148 ft) tall and 1.7 m (51⁄2 ft) in trunk diameter on very productive sites. The tallest on record is a tree over 210 years old growing in Estonia which ...
But, Christmas trees as we know them, began in 16th century Germany, when devout Christians brought dressed evergreen trees into their homes. And when early German settlers eventually landed in ...
