In the situation of forest-developed trees so much depends upon the Competitors from the trees within their battle for mild and nourishment that intervals of swift and gradual progress might alternate. Some trees, like southern oaks, preserve the same width of ring for many hundreds of years. On the whole, like a tree will get much larger in diameter the width of The expansion rings decreases.
