Society of American Foresters Temperate Coniferous Forest | Biomes Temperate evergreen forests are found predominantly in areas with warm summers and cool winters, and vary enormously in their kinds of plant life. In some, needleleaf trees dominate, while others are home primarily to broadleaf evergreen trees or a mix of both tree types. Temperate evergreen forests are common in the coastal areas of regions that have mild winters and heavy rainfall, or inland in drier climates or montane areas. The understory also contains a wide variety of herbaceous and shrub species. Structurally, these forests are rather simple, consisting of 2 layers generally: an overstory and understory. Temperate rain forests only occur in 7 regions around the world - the Pacific Northwest, the Validivian forests of southwestern South America, the rain forests of New Zealand and Tasmania, the Northeastern Atlantic (small, isolated pockets in Ireland, Scotland, and Iceland), southwestern Japan, and those of the eastern Black Sea.
Dutch Study Says Wi-Fi Makes Trees Sick A recent study by Dutch scientists found that Wi-Fi radiation could be responsible for sickness in urban-populated trees. Image: baltimoresun What would life be like without Wi-Fi, bringer of high speed internet access? Probably pretty inconvenient considering that millions of computer users around the world use it at home, at work and other public places to get online. Having access to wireless networks makes our lives easier, but according to a Dutch study from Wageningen University, this access may be compromising the health of trees. The study began five years ago in the city of Alphen aan den Rijn. According to an article from PC World : “The study exposed 20 ash trees to various radiation sources for a period of three months.

Tree Encyclopedia Trees have three principle features that distinguish them from all other plants. First, they have a woody stem, roots and branches which do not die back in winter, but continue to grow year after year. From the moment of its germination, a tree remains visible; from the tallest Sequoia to the smallest garden fruit tree, this principle of growth remains constant. Trees live longer than any other organism on earth. Trees commonly live more than 1,000 years, and many grow considerably older. Pando (Latin for “I spread”), aka “the trembling giant,” is a clone colony of male quaking aspen, (Populus tremuloides) a single living organism identified by identical genetic markers. Trees have been living on Earth for more than 370 million years, and today can be found almost everywhere from the Arctic Circle to the Sahara Desert. Family Aceraceae: Maples are some of our most familiar and beloved trees. Legumes harbor nitrogen-fixing bacteria in nodules in their root structures.

Global Justice Ecology Project: GlobalJusticeEcology.org , Hinesburg, VT Israeli biotech firm says its modified eucalyptus trees can displace the fossil fuel industry by John Vidal, environment editor, The Guardian, Thursday 15 November 2012 GM eucalyptus trees at five-and-a-half years old, grown in a field trial. FutureGene claims GM species grow thicker and faster than the natural plant, making it possible to be grown for energy generation.It's a timber company's dream but a horrific industrial vision for others: massive plantations of densely planted GM eucalyptus trees stretching across Brazil, South Africa, Indonesia and China, engineered to grow 40% faster for use as paper, as pellets for power stations and as fuel for cars. The prospect is close, says Stanley Hirsch, chief executive of the Israeli biotech company FuturaGene. Hirsch claims the gene-altering technique is an industrial "game-changer" and integral to the UN's vision of a future "global green economy". "Our trees grow faster and thicker. FuturaGene is no small start up company.
