Question

What is the flag tree?

Answer 1

Hint: Flag tree can be called a variation of Krummholz formation, the krummholz are also known as kneehole and are specifically found in the subarctic region These are subalpine trees, and their shape is given by exposure to various natural agents including the freezing winds.

Complete answer:
Flag trees are named so, due to resemblance with the pole of a flag due to the absence of branches on the windward side and the leeward side containing branches. The flag trees have branches on one of their sides because the branches on the other side of the tree that is against the wind are killed or deformed by the constant wind that is strong enough to damage the branches, hence gives the tree a flag-like appearance. This appearance is seen only in the upper portion of the tree or the trunk portion that is exposed out of the snow, the portion below the snow will have normal growth. These trees are mostly seen in the main central and some are also seen in the southern part of the Appalachian mountains and are mostly noticed in either the hilly or plateau region of the Allegheny mountains.

Note: The trade winds found near the equator or in the tropical regions can also form this type of tree. The side exposed to winds also has an increased rate of transpiration and decreased rate of photosynthesis. Windward means upwind or from where the wind is blowing and the leeward side is the side away from the wind.
