Day 1 EVERYONE NEEDS TREES
Trees… time to think! 1. Draw a tree on the space provide in your guided notes (make it extra pretty ) 2. Label as many parts of the tree that you know (not your neighbor ). 3. Lets see how you did!
Parts of a Tree Roots an anchor for the above-ground biomass absorbs water and nutrients from the soil Trunk main structure of a tree covered in bark supports the branches supported by and attached to the roots Branches woody structure connected to the central trunk of a tree Twigs small thin terminal branch Leaves: an above ground organ specialized for photosynthesis usually flat and thin Above-ground biomass VOCAB: 1.Biomass 2.Structure 3.Woody 4.Terminal 5.Organ
Thinking back to our opening exercise… what are some products that you know come from these parts of a tree?
Products Made from Trees fuel lumber furniture plywood cinnamon carpeting suntan lotion nuts cosmetics paper products Soap sugar & syrup Gum Crayons Fruits Can you think of any more? What part of the tree do you think these products come from?
Products come from all parts of the tree Wood: Fuel lumber for houses Furniture Plywood Cellulose is the major component of wood which makes paper and paper products: Carpeting Suntan lotion Bark: Cinnamon Sap: Cosmetics Soap Sugar & Spice Crayons Fruit, Leaves & Seed: Fruits Nuts What would your life be like without all of these products?
Value of Trees What are some observations you can make about this landscape?
What are some observations you can make to compare this landscape from the last?
Benefits of Trees Social Communal Environmental Economic
Social Benefits Make life more pleasant Become personally attached Frequently planted as living memorials Resistance of residents to remove trees Feel peaceful, restful and secure around trees Trees foster safer, more sociable neighborhood environments (Sullivan and Kuo, 1996). Trees absorb high-frequency noise which is the most distressing for humans (Miller, 1997). Hospital patients that see trees need less medication and have faster recovery times (Ulrich, 1985).
Communal Benefits privacy recreation emphasize views direct pedestrian traffic reduce glare and reflection provide background to and soften, complement or enhance architecture cast shade in the evenings that encourages residents to come out and enjoy walks and bike rides slows drivers as trees make them feel enclosed in the tree tunnels
Environmental Benefits Moderate climate moderate the effects of sun, wind and rain temperature in the vicinity of trees is cooler Improve air quality leaves filter the air by removing dust, smoke and particulates leaves absorb carbon dioxide and give off oxygen absorb air pollutants such as ozone, carbon monoxide and sulfur dioxide Conserve water trees intercept water, store it and reduce storm runoff and flooding help keep water clean and drinkable tree roots can trap and filter out contaminants before entering the water supply Harbor wildlife provide shelter and food for a variety of birds and small animals
Economic Benefits: Direct The savings in energy costs and the increase in property value directly benefit homeowners. Energy costs air-conditioning costs are lower in a tree-shaded homes heating costs are reduced when a home has a windbreak Increase in property value trees increase in value as they mature landscaped homes are more valuable
