Vegetation
Cultivated fields and livestock are generally found in elevations below 800 m. Between 800800 metres (2,600 ft) and950 metres (3,120 ft) elevation, grasses and wood shrubs (maximum height of 3 metres (9.8 ft)) are recorded. Primary forest in patches with trees (30 metres (98 ft) high and 50 centimetres (20 in) diameter) is found above 1,000 metres (3,300 ft) elevation with canopy of about 80% closed. This forest has dense undergrowth with large vines, tree ferns and rhododendrons. Banana, bamboo and secondary scrub grow on both sides of foot tracks in the forests. The forest also has an abundance of cascading streams, seepage streams from lime stone formations, waterfalls, glides, and pools. The stiff lime stone vertical rock face is seen above 1100 m on the northeast face of Mt Muong Cha, while its southwest slope exhibits a much gentler grade, and is converted into agricultural fields. Above 2,000 metres (6,600 ft) elevation, there is a montane mixed semideciduous and evergreen cloud forest. This forest has an understory of Ericaceae with shrub and epiphytic species of rhododendron and vaccinium. Species of Lauraceae, with Ericaceae and Oleaceae (at higher elevations with taxa in the Fagaceae, Myrsinaceae and Araliaceae are also recorded. Most of the tree trunks are covered with bryophyte mosses in this zone.

Famous quotes containing the word vegetation:
“We love to see any redness in the vegetation of the temperate zone. It is the color of colors. This plant speaks to our blood.... What a perfect maturity it arrives at! It is the emblem of a successful life concluded by a death not premature, which is an ornament to Nature. What if we were to mature as perfectly, root and branch, glowing in the midst of our decay, like the poke!”
—Henry David Thoreau (1817–1862)
“I would not have every man nor every part of a man cultivated, any more than I would have every acre of earth cultivated: part will be tillage, but the greater part will be meadow and forest, not only serving an immediate use, but preparing a mould against a distant future, by the annual decay of the vegetation which it supports.”
—Henry David Thoreau (1817–1862)
“When the ground was partially bare of snow, and a few warm days had dried its surface somewhat, it was pleasant to compare the first tender signs of the infant year just peeping forth with the stately beauty of the withered vegetation which had withstood the winter ... decent weeds, at least, which widowed Nature wears.”
—Henry David Thoreau (1817–1862)
