What is timberline in ecology?

The forest line or timberline represents the edge of the closed upper montane forest (note, “montane” is the biogeographic term for the next lower belt, not to be confused with “mountain”), the zone of gradual forest opening near the treeline is often termed treeline parkland, and the uppermost position where tree ...

What determines the timberline?

timberline, upper limit of tree growth in mountainous regions or in high latitudes, as in the Arctic. Its location depends largely on temperature but also on soil, drainage, and other factors.

Where do trees stop growing in Canada?

The treeline marks the limit of trees latitudinally on continental plains and altitudinally on highlands and mountains (where it is sometimes called the timberline). Tree species still occur beyond this limit, but in shrub form, extending to the "tree-species line."

How does altitude affect tree growth?

Because of the limits set by altitude, trees do not grow beyond the timberline (tree line). At that altitude air pressure is less and carbon dioxide is greatly reduced. ... Near the timberline, trees become smaller, scattered. Growth becomes stunted or distorted.

What does timberline mean in geography?

Trees grow all over the world, in many different types of weather. But above certain elevations, trees just cant grow. ... This imaginary line on the Earth is called the timberline, or the tree line. The timberline is usually a point where there isnt enough air, heat, or water to keep trees alive.

What is timberline in Himalayas?

In this review, the term 'upper timberline' is used sensu Holtmeier (2000; 2003), i.e. it refers to the upper elevational limit of forests in high mountains, that may occur as an abrupt boundary, but usually forms a transition zone, a more or less wide ecotone, between closed contiguous forests and single, often ...

Why do pine trees grow on mountains?

The areas higher up on mountains are windier, colder, and receive more snow than places lower on the mountains or in valleys. The weather also stays colder longer higher up in the mountains, which means there is a shorter growing season – the time when plants and trees can grow.

What causes treeline?

The tree line is the elevation at which trees stop growing-either because of the low temperatures, or lack of pressure and moisture. Tree lines are pretty consistent between the latitudes of 30°N and 20°S. But the farther away, the lower the tree line gets.

What elevation is timberline in Colorado?

In Colorado, timberline -- the boundary between forest and tundra -- falls between 11,000 and 11,500 feet above sea level. The alpine environment is harsh, with high winds, short summers, heavy snows and extremely cold temperatures.

Why there is no tree in tundra?

Tundra is found at high latitudes and at high altitudes, where the permafrost has a very thin active layer. The active layer of tundra is too thin for trees to grow, because it cannot support a tree's roots. Tundra is sometimes called a cold desert. ... The reason is that the permafrost beneath it is like a barrier.

Are there trees in Nome AK?

Welcome to the Nome Alaska, an Arctic landscape with no trees.

Does Alaska have trees?

In Alaska, there are 129 million forested acres across the state. Sitka spruce, hemlock and cedar are the dominant species in Southeast and Southcentral, while white spruce, black cottonwood, aspen, and paper birch are found in the Interior forests.

How does altitude affect wildlife?

The higher we go the colder it gets. Due to these reasons only plants and animals adapted to living in cold areas can survive. That is why altitude affects wildlife and vegetation.

How does altitude affect vegetation and wildlife?

Altitude affects the amount of sunlight and water that plant receives. At high altitudes, short-wave radiation is seen. Not all plants can survive this type of sunlight. Plants in lower altitude can be affected by droughts, compared with plants of higher altitude.

How does altitude affect forest?

FORESTS CHANGE WITH ALTITUDE

Environmental conditions vary with altitude – temperature, soil type, rainfall, humidity – and this influences what grows there. ... A few other studies have found that at higher altitudes, a higher proportion of a tree's biomass is stored underground.
