Trees are major capital assets in cities across the United States. Just as streets, sidewalks, public buildings and recreational facilities are a part of a community's infrastructure, so are publicly owned trees. Trees -- and, collectively, the urban forest -- are important assets that require care and maintenance the same as other public property. Trees are on the job 24 hours every day working for all of us to improve our environment and quality of life.
Colorado’s urban forest provides many environmental benefits to our community. Aside from the obvious aesthetic benefits, trees within our urban forest improve our air, protect our water, save energy, and improve economic sustainability.
Unlike urban areas in the eastern U.S., canopy cover in Colorado decreases along an urban to rural gradient. In other words, since most trees have been planted much of the tree cover is in urban areas as opposed to “natural lands”. Therefore, estimated pollutant uptake rates are higher for residential compared to natural or unmanaged lands. Possible management implications of these estimates are that air pollutant uptake benefits from tree planting may be optimized by planting in areas where air pollutant concentrations are elevated and where relatively high planting densities can be achieved thereby enhancing the health of urban dwellers.
Parents Like a Tree, Give Us Unconditional Love
How do you treat your parents? Always argue until 12 o’clock? Kiss them all the time?
Parents are the one always take care of us, how do you treat them? before I start I would like to tell you a story about a huge apple tress and the little boy:
Once upon a time, there was a huge apple tree. A little boy loved to play with it every day. He loved to climb on the rigid branches, eat its apples, and also take a nap under it. At that time, he loved the tree and the tree loved him too. As the time went by, the little boy has grew up and he no longer spent his time with the tree every day. One day when the boy passed by the tree, the tree said, “I’m glad to see you, my little boy. Can you play with me?”. “I’m no longer a little boy, I has grew up,” The boy replied and run away.
As he grew up, he wanted toys. But he knew buying toys need money, so he asked the tree, “I need money to buy toys, can you help me?” And the tree replied, “Sorry, I don’t have money. Instead, you can pick my apples and sell them. Then you will have money.” The boy became excited. He grabbed all the apples on the tree and left. But he didn’t go back again. Until…
Of course, the tree was really disappointed. It didn’t want the boy to leave it because they had a close relationship when he was young. A few years have passed, the boy returned again and the tree was extraordinary happy and invited him, “Come and play with me.” The boy neglected it and lift. Before he left, he said that he had to work to support his family and need a house for his family. Once again, the tree did not have a house. But it let the boy chop off its branches to build his house. The boy cut all the rigid branches off and left. The tree was glad to see him so happy. Nonetheless, the boy didn’t return for a long, long period of time. The tree became more disappointed.
In a very hot summer, the boy returned. This time he wanted to go sailing to relax with his family and friends. “What can you help me?” The boy asked. The tree is not a magician, it could not have a boat. The tress thought for a while and said nicely, “You can use my trunk to build your boat. You can sail far away and be happy.” So the boy cut down the tree and used its trunk to make a boat. He went sailing and disappeared again for a very long time.
