Western Himalayan Subalpine Conifer Forests
The Western Himalayan subalpine conifer forests is a temperate coniferous forests ecoregion of the middle and upper elevations of the western Middle Himalayas of Nepal, India, and Pakistan. Setting The ecoregion forms a belt of coniferous forest covering on elevations between . It extends west from the Gandaki River in Nepal, through the Indian states of Uttarakhand, Himachal Pradesh, and Jammu and Kashmir into northern Pakistan. This belt of conifers is the highest expanse of woodland to be found on the slopes of the Himalayas, treeless alpine scrub lying just above its ecotopic frontier. It is a valuable ecosystem as many Himalayan birds and animals migrate seasonally up and down the mountains spending part of the year in the conifer forests, so conservation is a high priority. This ecoregion is drier than the Eastern Himalayan subalpine conifer forests, which receive more moisture from the Bay of Bengal monsoon. Flora Several distinct forest types are found in this ecoregio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abies Gamblei
Firs are evergreen coniferous trees belonging to the genus ''Abies'' () in the family Pinaceae. There are approximately 48–65 extant species, found on mountains throughout much of North and Central America, Eurasia, and North Africa. The genus is most closely related to '' Keteleeria'', a small genus confined to eastern Asia. The genus name is derived from the Latin "to rise" in reference to the height of its species. The common English name originates with the Old Norse ''fyri'' or the Old Danish ''fyr''. They are large trees, reaching heights of tall with trunk diameters of when mature. Firs can be distinguished from other members of the pine family by the way in which their needle-like leaves are attached singly to the branches with a base resembling a suction cup, and by their cones, which, like those of cedars, stand upright on the branches like candles and disintegrate at maturity. Identification of the different species is based on the size and arrangement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
