- Water quality is improved by trees by protecting aquifers and watersheds and also slowing and filtering rain water.
- Water evaporation occurs through tree leaves, lowering the ambient temperature.
- Photosynthesis is the process by which plants and trees make their food using sunlight, water, nutrients, and carbon dioxide.
- The life of a tree is spent absorbing carbon dioxide and producing oxygen, renewing our air supply.
- A single tree produces about 260 pounds of oxygen each year. An acre of trees provides enough oxygen for eighteen people.
- The tree seed that stays in flight the longest is the cottonwood tree seed, according to tree service companies. The ultra-light, white fluff hairs surrounding the seed can carry it for several days through the air.
- Up to 2.6 tons of carbon dioxide is removed by each acre of trees per year.
- An acre of trees can absorb as much carbon in one year as a car driven 8700 miles.
- Three tons of carbon would be returned to the atmosphere upon the death of one 70-year old tree.
- The most productive stage of carbon storage for a tree happens at about 10 years.
- Tree roots stabilize soil and prevent erosion.
- Buildings are made up to 20 degrees cooler by shade trees in the summer.
- Yearly heating and cooling costs are reduced by 2.1 billion dollars by trees’ shade and shelter.
- Cambium, phloem, xylem and cork make up the body of a tree.
- The longest living organism on the earth is the tree.
- Trees move water from the roots to the leaves via the xylem.
- Glare and reflection control is reduced by trees located along roadsides.
- The the life span for an average tree in metropolitan area is only about 8 years.
- Food and shelter for wildlife is provided by trees.
- Noise pollution is provided by trees by acting as sound barriers.
- Protection from downward fall of rain, sleet, and hail is provided by trees.
- The oldest trees in the world are Bristlecone Pines. The USA has some 4,600 years old.
- The coast redwood in California is the world’s tallest tree and measures 360 feet.
- The Ada Tree of Australia has a circumference of 50 feet. It is 236 feet high and has a root system that takes up more than an acre.
- The General Sherman is one of the tallest soft wood trees. It is 275 feet tall, and its diameter is over 36 feet at the base, located in the Giant Forest of Sequoia National Park in California. It is a giant sequoia tree and by volume, it is the largest known living single-stem tree on Earth. That is the first picture below. The next is of a stand of sequoias and the next is a nice picture of palmetto trees on Sullivan’s Island, SC.
