OBJECTIVE FORESTRY

Detailed explanation-1: -In a few cases it has been shown that a tree can sometimes make two growth rings in a season if conditions are very dry in the early part of the year followed by heavy rains in the summer and a late fall.

Detailed explanation-2: -Each year, the tree forms new cells, arranged in concentric circles called annual rings or annual growth rings. These annual rings show the amount of wood produced during one growing season.

Detailed explanation-3: -The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring plus one dark ring equals one year of the tree’s life.

Detailed explanation-4: -growth ring, in a cross section of the stem of a woody plant, the increment of wood added during a single growth period. In temperate regions the growth period is usually one year, in which case the growth ring may be called an “annual ring.” In tropical regions, growth rings may not be discernible or are not annual.
