The tallest tree in Australia which also happens to be the world’s second tallest tree is commonly known as the Centurion. The Eucalyptus regnans was first measured in the year two thousand and eight by two Tasmanians. The first recorded height of the tree was ninety-nine point seven metres. The second measurement in the year two thousand a fourteen recorded a height of ninety-nine point eight two. The third recorded height, which is also the current height is about a hundred and point five metres. The Centurion is also currently the world’s tallest hardwood as well as the tallest flowering plant. The Centurion has taken two hundred years to reach its optimum height which is five times less the time taken by other redwoods to attain such height.
The giant trees of the world grow to a tune of three hundred feet and are the world’s known largest living organisms. Giant Sequoias are the world’s best known giant trees. Some of the features of the giant sequoias are as follows;
- They have a lifespan of up to three thousand years
- The giant species branch out and their branches can be as thick as eight feet.
- They have very thick barks approximately three feet thick.
- They are very wide and can attain a width of thirty-five feet.
- They come third in terms of long lifespan after Alerce trees and Bristlecone pines.
- Giant sequoias grow continually without halting until they die
- They hardly reproduce and take about twenty years to reproduce
Most giant trees will take several centuries to attain their optimum maturity level, but this depends on their habitat and the prevailing climatic conditions. Some giant trees grow fast initially, and the growth rate reduces over time due to their height which limits the movement of minerals required for growth.
Why we need to protect giant trees?
Human activities like industrialization, lumbering and agriculture pose a significant threat to the existence of giant trees. There is a gradual increase in demand for hardwood timber all over the world. This demand has resulted in the logging of the giant trees. Industries have impacted a lot on the climate due to the emission of harmful substances to the environment. Snowy and rising temperatures climatic conditions have all retarded the growth of giant trees which over time may cease entirely. Following these reasons, we need to protect the giant trees for our future generations because they are also hard to propagate. Wiping out giant trees which are natural habitats for other wildlife may also wipe them in the process.
