Impact On The Environment
ABC News reported on 17 June 2009 that a study has been carried out by environmental scientist Professor Brendan Mackey of the Australian National University which identified that mountain ash forests in Victoria’s Central Highlands as the best in the world at locking up carbon.
Mackey and colleagues found the highest amount of carbon was contained in a forest located in Victoria’s Central Highlands, which held 1900 tonnes of carbon per hectare. This most “carbon-dense” forest was a stand of unlogged mountain ash over 100 years old. Mountain ash live for at least 350 years, according to Mackey.
"The Big Tree" (previously thought to be the tallest remaining), is about 15 metres around the base. The sign at its base states its dimensions and the tonnage of timber that could potentially be cut from it. A few such trees of extreme size have been recorded by Forestry Tasmania as worthy of preservation.

Trees that have been identified as above the permissible height for logging are left isolated when the forest around them is logged. If reduced in height by storm, the tree becomes loggable.

Famous quotes containing the words impact on, impact and/or environment:
“Too many existing classrooms for young children have this overriding goal: To get the children ready for first grade. This goal is unworthy. It is hurtful. This goal has had the most distorting impact on five-year-olds. It causes kindergartens to be merely the handmaidens of first grade.... Kindergarten teachers cannot look at their own children and plan for their present needs as five-year-olds.”
—James L. Hymes, Jr. (20th century)
“As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)
“Today the young actors regard their environment with rage and disgust. They regard their Master not as disciples regard their Master, but as slaves regard their Master.”
—Judith Malina (b. 1926)
