Does the tree bear cones and have leaves that are needle-like?CLUE: These trees are called CONIFERS (cone-bearing) and most are EVERGREEN (trees with needles or leaves that remain alive and on the tree through the winter and into the next growing season). Does the tree bear cones that are sometimes berry-like and have leaves that hug the twig and are scale-like or awl-shaped?CLUE: These trees are called CONIFERS (cone-bearing) and most are EVERGREEN. Does the tree have leaves that are flat and thin and generally shed annually?CLUE: These trees are called BROADLEAF, (a tree with leaves that are flat, thin and generally shed annually) most are DECIDUOUS (shedding all leaves annually) and bear a variety of fruit and flowers.

Global Justice Ecology Project: , 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. Temperate Coniferous Forest 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. Many species of trees inhabit these forests including pine, cedar, fir, and redwood. The understory also contains a wide variety of herbaceous and shrub species.

Forest certification: a small step towards sustainability It can be hard to know whether the forest products you buy have been produced sustainably. Forestry certifications were established to give a bit more certainty, but what do they really mean? When you buy a certified product, are you necessarily helping the environment? A short history of certification The two international forestry certifications - Forest Stewardship Council (FSC) and Program for the Endorsement of Forest Certifications (PEFC) - have had an interesting history over the past 20 years. There are often clouded interpretations and miss-interpretations of how each came about.

How tall can a tree grow? - Valentin Hammoudi As explained in this lesson, at the base of the tree the phloem sap has delivered most of its sugar and is therefore quite watery. Just next to it, the xylem sap is rich in minerals, which were mostly absorbed by the roots. This unbalanced rate of water between phloem and xylem leads to water movement from the first one to the latter one, due to a phenomenon called osmosis. Unsurprisingly, a mirrored water exchange takes place at the top of the tree. Once it has delivered its nutrients and reached the tree’s top, the xylem sap is very watery, and by a similar osmotic movement, water goes from the xylem to the phloem enabling the production of new phloem sap. The water is then circulating in a partially closed circuit, with input from the roots and output from the leave.

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?

Earth Floor: Biomes Deciduous Forest The mid-latitude deciduous forest biome is located between the polar regions and the tropics. Because of its location, air masses from both the cold polar region and the warm tropical region contribute to the changes of climate in this biome. Photo © Mid-latitude deciduous forests have both a warm and a cold season (see climograph). Precipitation ranges from 30 to 60 inches and is evenly distributed throughout the year.

UW - Brockman Memorial Tree Tour Dedication This tour is dedicated to the memory of Professor C. Frank Brockman (1902-1985), who capped an influential, productive career in forestry and outdoor recreation by producing in 1980 the original University of Washington tree tour. Edited by Louise M. Hastie, that eight-page publication featured 81 campus trees, and had to be reprinted by popular demand. Along with the tour, Brockman authored five articles about campus trees for the U.W. Tree Disease identification, symptoms, treatment options for tree diseases There are many different diseases that affect landscape trees and shrubs. Control of tree and shrub diseases cannot be properly accomplished until the disease pest is identified. Identification of tree and shrub diseases is crucial because, although most diseases can be controlled, there are some diseases that cannot be controlled. Disease control on landscape trees and shrubs can sometimes be accomplished by more than one method, depending on the particular disease that if infecting your landscape plants. Fungicides are often used to control diseases on landscape trees and shrubs and fungicides may be sprayed, injected into the tree trunk, or even injected into the soil surrounding the roots of the tree or shrub.

Deciduous Forest Deciduous biomes are located primarily in the eastern half of the United States, Canada, Europe, parts of Russia, China, and Japan. Climate The average temperature of the forest is about 50 degrees F. The average amount of rainfall in the forest is 30 to 60 inches a year. Temperate Deciduous Forest The Temperate Deciduous Forest The temperate deciduous forest occupies much of the middle of the Whittaker diagram, and to those of us who live here, it sure feels that way. Rapid changes from cold and dry to wet and warm or to any of the other corners of the climate envelope are often swift and dramatic. A favorite saying among the natives is "if you don't like the weather, wait a minute". Of course, we are talking about climate here, not weather, but the principle remains.
