Trees time to think! 1. Draw a tree on the space provided in
your guided notes 2. Label the parts of the tree that you know. 3.
Lets see how you did!

Thinking back to our opening exercise what are some products
that you know come from these parts of a tree?
Slide 9
Products Made from Trees Fuel Lumber Furniture Plywood Cinnamon
Carpeting Suntan lotion Nuts Cosmetics Paper products Soap Sugar
& syrup Gum Crayons Fruits Rubber Cork Can you think of any
more? What part of the tree do you think these products come
from?
Slide 10
Products come from all parts of the tree Wood: Fuel lumber for
houses Furniture Plywood Cellulose (major component of wood): Paper
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?
Slide 11
Value of Trees What are some observations you can make about
this landscape?
Slide 12
What are some observations you can make to compare this
landscape from the last?
Slide 13
Sustainable Forestry Forest area is cut down and trees are
allowed to grow back Environmental impacts are minimized Healthy
landscape with areas of early succession and old growth forest
Forest area is cut down and the land is put to another use Timber

Slide 14
Benefits of Trees Social Communal Environmental Economic
Slide 15
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
absorb high-frequency noise, which is the most distressing for
humans Hospital patients that see trees need less medication and
have faster recovery times
Slide 16
Communal Benefits Privacy Recreation Direct pedestrian traffic
Reduce glare and reflection Provide background to 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
Slide 17
Environmental Benefits Moderate climate moderate the effects of
sun, wind and rain temperature in the vicinity of trees is cooler
Leaves improve air quality filter the air by removing dust, smoke
and particulates absorb carbon dioxide and give off oxygen absorb
air pollutants such as ozone, carbon monoxide and sulfur
dioxide
Slide 18
Environmental Benefits Trees conserve water intercept water,
store it and reduce storm runoff and flooding help keep water clean
and drinkable roots can trap and filter out contaminants Wildlife
Habitat provide shelter and food for a variety of insects, birds
and small animals
Slide 19
Trees Provide Wildlife Food and Shelter
Slide 20
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
