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. Animals Precipitation in the temperate deciduous forest is spread throughout the year.

The Deciduous forest does not have much vegetation but there are many trees that contain outrageous amounts of flowers.

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 © 2000-www.arttoday.com 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. "Deciduous" means to fall off, or shed, seasonally. Back | Next
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. According to environmental NGOs, governments failed to agree on how to address rapid deforestation, mostly in the tropics. Yet another account is that the economically poor but forest-rich tropical nations refused to bow to western NGO pressure, forcing them to take up a forestry standard that could be used as some form of trade barrier. FSC, PEFC: what’s the difference? So how does Australia stack up?

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. Introduction About 480 different kinds of trees beautify the U.W. If you are using the print version of the Brockman Memorial Tree Tour, please see the addendum to the print booklet.

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. As water gets evaporated at the leaves, the pressure inside the xylem rises which creates the so-called follicular aspiration making the xylem sap move upwards.

International Day of Happiness You might think the International Day of Happiness is a day to practise positive thinking or to give thanks for the things in your life that make you happy. But it's actually a United Nations project which has a more serious purpose. The UN thinks happiness will only be for everyone when the people of the world are equal. Why 20 March? On this date (and also on 23 September), the centre of the sun is directly above the Earth's equator, which is called an equinox. How did the idea start? The idea goes back to 1972, when the King of Bhutan, Jigme Singye Wangchuck, said that we should measure a country's progress by its happiness and not just how much it produces or how much money it makes. The man behind the International Day of Happiness In 2011, a UN adviser called Jayme Illien suggested the idea of an international day to increase happiness. The World Happiness Report The UN measures and compares the happiness of different countries in the World Happiness Report. Source Why 20 March? Source
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. 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. Structurally, these forests are rather simple, consisting of 2 layers generally: an overstory and understory. The Klamath-Siskiyou ecoregion of western North America harbors diverse and unusual assemblages and displays notable endemism for a number of plant and animal taxa.
Glossary of Forest Engineering Terms | Forest Operations Research | SRS Glossary of Forest Engineering Terms Index Foreword The terminology used in forest engineering and harvesting has evolved over many years, beginning with the early lumberjacks who cut trees for homes and industry. A literature review was conducted to assemble the terms from published sources in an attempt to exclude colloquial terminology. Although this collection does not include all timber harvesting and forest engineering terms, it is hoped that the compilation will provide a sufficiently extensive glossary for forest operations. A-frame Two wood or metal uprights mounted in the shape of the letter 'W' to support lead blocks at the upper end (22). Two poles lashed together with a crosspiece in the form of an 'W' with a block hung in the apex of the poles used as a loading device with the poles or sawed timbers joined at the top, anchored at the base, and guyed with cable (8). Aboveground biomass Aboveground portion of a tree, excluding the root system (29). Abney level Access Adverse grade Age
i-Tree - Tools for Assessing and Managing Community Forests Trees on the Moon • Forest Monitor Are there actually trees on the Moon? Not really…but there are two cases when we can find “Moon trees” on Earth. In my opinion, as “Moon trees”, firstly we can call trees grown from 500 seeds taken into orbit around the Moon by Stuart Roosa during the Apollo 14 mission in 1971. Secondy, trees that grow in the Craters of the Moon in Idaho, USA. This post is about the Craters of the Moon National Monument and Preserve, as some time ago, I had a big pleasure to visit this “weird and scenic landscape peculiar to itself”. Craters of the Moon National Monument and Preserve is a U.S. >>READ ALSO: Everglades National Park is not a swamp! Many lava flows exist on Earth’s actual moon, but astronomers confirmed that most lunar craters resulted from meteorite impacts, not volcanism. But where is the volcano? In fact, these vast volumes of lava issued not from one volcano but from a series of deep fissures – known collectively as the Great Rift – that cross the Snake River Plain. Spatter cones Related
How to regrow a forest: Get out of the way This story was produced in partnership with the Pulitzer Center on Crisis Reporting and the National Geographic Society. Imagine a black hole in the center of a green donut, Malcolm North said. A USDA forest ecologist in the Sierra Nevada of eastern California, North was at the center of a new experiment in forestry with global implications. That put him at the center of one of the hottest new fields of climate adaptation—and a quiet revolution in his own field. They called it “pines in lines,” and over the last century it became industry standard as the Forest Service replanted the native mixed-species forests of Western conifers with trees for commercial harvest. But that method—relying not only on armies of sowers but also foresters who come back, years later, to “clean up the mess”—has become prohibitively expensive for a Forest Service facing the intersection of a more volatile climate with flat funding. “The consequences of getting it wrong can be really destructive,” he said.
