It is estimated that-at the beginning of European settlement-in 1630 the area of forest land that would become the United States was 423 million hectares or about 46 percent of the total land area. By 1907, the area of forest land had declined to an estimated 307 million hectares or 34 percent of the total land area. Forest area has been relatively stable since 1907. In 1997, 302 million hectares- or 33 percent of the total land area of the United States was in forest land. Today's forest land area amounts to about 70 percent of the area that was forested in 1630.
There are many facts as Canada's forested land accounts for 10% of the worlds forest. Another reason why Canada sinks more carbon than it emits, because trees take carbon from the air and turn it into wood. Canada's forests have always benefited from warming climates. Global Warming opens up even more areas to larger trees. Summers become longer, winters shorter giving trees more growing time. Canada's forest use has not been great in the past. There is almost no old growth rain-forest remaining in Canada. The forests called rain-forests today are but shadows of what was there. Basically any thing that grows back green is considered rain-forest. And Canada still allows clear cutting and the export of raw logs. These poor forest practices have been banned in many places around the world. Replanting clear cut areas with single species has given insects lots of food and as much as 15 million ha are affected. Forest fires take another 3 million ha but Canada's forests are large and resilient. Forest land use is improving. Unlike urban areas in Southern Canada industrial sites like those in Canada's Oilsands restore the forest when lands are no longer needed. And a forest is much more than a few trees. Restoration includes much more flora and fauna.
1 hectare= 0.01 square kilometersAnswerHectares are used in farm lands to check how much area has been cultivated.1 hectare = 0.01 km^2
Yes, Illinois has had forest fires.
where has some of the acid rain and forest decline been observed
The three main objectives of the Canadian Armed Forces are clear and have been their objectives since the Canadian Armed Forces were formed. The objectives are to defend Canada, to defend North America, and to defend Canada's allies.
Canada has been visited by Susan.

Saint-Martin's National Nature Reserve, which covers 3060 hectares, is located in the north-eastern part of the island. The offshore part of the Reserve is its largest area, at over 2900 hectares. The mangroves are dominated by the Red Mangrove (Rhizophora mangle), which can be found in the salt ponds. Ponds and mangroves are highly productive biological systems that provide a safe haven for young crustaceans and fish. They also provide food and shelter for many birds (around fifty species have been counted).
It is simply referred to as an "Old Growth Forest"
According to the International Ramsar Wetland convention a pond is less than 8 hectares in size, and a lake is larger than 8 hectares. However this definition has not been accepted by all biologists and researchers.
"Has been" is used for present perfect tense, indicating an action that started in the past and continues into the present. "Had been" is used for past perfect tense, indicating an action that was completed before another past action. "Have been" is used for present perfect continuous tense, indicating an action that started in the past and is still continuing.
