Here is a map showing the general location of Australia’s tropical and temperate forests.
Australia’s forests face many threats including habitat modification, impact of exotic species, altered fire regimes, ecologically unsustainable resource use, and climate change.
In 1945, 61 percent of Thailand was covered by forest. This percentage dropped to 34 percent and currently about 28.4 percent of Thailand is covered by forest.
From 1990 to 2000 the rate of deforestation has been estimated at about 0.72 percent. From 2000 to 2005 deforestation had reduced to about 0.4 percent per annum.
The main driver of deforestation in Thailand is the rapid increase in population. This increase is most evident in the north eastern region where the forest is cleared for farming to feed the nation’s growing population.
The Government of Thailand has encouraged reforestation programs and had put in place a ban on all commercial logging in 1989.

The world’s tropical rain forest is located in South and Central America, Africa, Asia and Australia. It is the home for about half of all animal and plant species in the world. Also over a quarter of all modern medicine come from plants found in this type of forest. It is often called “the world’s largest pharmacy”. Vast amounts of the worlds carbon dioxide is stored in these forests. Therefore deforestation would lead to the release of this carbon into the atmosphere accelerating global warming.

The Boreal Forest – The World’s Carbon Storehouse
Canada’s Boreal forest (depicted in green in the map below) is part of the larger Biome called the “Taiga”. The Taiga covers the northern areas of the Arctic tree line. Canada’s Boreal forest in particular is considered the largest carbon storehouse in the world. It houses 22 percent of the the carbon stored in the world’s land surface. The Boreal stores twice as much carbon per unit area compared to tropical forests. This is due to the cold temperatures which preserve the soils resulting in deep organic soils that are thousands of years old.
The Threat to the Boreal Forest
Global warming and deforestation have threatened to release large amounts of carbon from the Boreal forest. 90 percent of all of Canada’s carbon is stored in the Boreal region. It is estimated that 186 billion tons of carbon is stored in the soil therefore destruction of the forest would greatly accelerate global warming. In response to this threat the Canadian Government implemented a plan to protect 25 million acres of Boreal land in November 2007.
