Champions in size and value.Like the miner's canaries of old, trees warn us of environmental danger. They react early to acid rain, air and water pollution, drought drought, abnormally long period of insufficient rainfall. Drought cannot be defined in terms of inches of rainfall or number of days without rain, since it is determined by such variable factors as the distribution in time and area of precipitation during and before , and climate change. Trees are also harbingers of environmental health. They flourish This article is about magic term. For 2006 film, see Flourish (film). A Flourish is a visual display of skill performed with playing cards to show the skill or ability of the performer. when conditions that suit their species are good - rainfall and drainage, nutrients, sunlight and soil. They thrive where man has protected and cared for the land and the trees. This is perhaps their greatest role as indicators - showing us where we have made it possible for them to reach their full grandeur. As the largest and oldest living things Living Things may refer to:
But there are even better reasons for us to help trees reach their full potential. Trees double their environmental contributions after 35 years. That means twice as much carbon sequestered se·ques·ter v. se·ques·tered, se·ques·ter·ing, se·ques·ters v.tr. 1. To cause to withdraw into seclusion. 2. To remove or set apart; segregate.

In cities, when trees are given the space to properly grow above and below ground and can reach maturity, they cast more cooling shade and can better clean the air and filter rainwater. The National Register of Big Trees The National Register of Big Trees is a list of the largest living specimens of each tree variety found in the continental United States. A tree on this list is often called a National Champion Tree. recognizes champion trees of 687 species, each the largest known of its kind. Exemplars of the arboreal arboreal pertaining to trees, treelike, tree-dwelling. world, they clearly demonstrate the potential all trees have to provide significant environmental values to the earth and all who share it. They capture our imagination and deserve our appreciation. This Register salutes all they've experienced and can provide - and the people who hunt and care for them. As you look for the titleholders among your favorite species or for the champs near where you live or work, join us in paying tribute to these giants among trees. And remember the rallying cry Noun 1. rallying cry - a slogan used to rally support for a cause; "a cry to arms"; "our watchword will be `democracy'" war cry, watchword, battle cry, cry catchword, motto, shibboleth, slogan - a favorite saying of a sect or political group 2. of Joseph Stearns, forester and catalyst for the Register, who wrote in 1940: "Let every tree lover, every forester, every lumberman rally...to fight for the preservation of our biggest tree specimens." If we fail to heed that still-resonant challenge, we have only ourselves to blame for the results. We will lose not only our environmental "early warning signs," but an arboreal legacy key to our future global environmental health. |
