Oxygen Replenishment - in the process of photosynthesis, trees convert carbon
dioxide and water into carbohydrates and oxygen
Carbon Dioxide Sequestration - in order to photosynthesize and release oxygen,
trees absorb carbon dioxide from the atmosphere
Save Energy - as few as 3 trees around your home can cut air conditioning bills in
half
Clean ground water - the hair-like root fibers of trees help filter ground water,
trapping nutrients and pollutants that could contaminate it
Pollution Control - tree leaves and roots act as natural filters of air and water
(rain and ground), removing particulate matter
Soil Retention and Rejuvenation - tree roots hold soil in place so it cannot easily
be washed away by wind or water; the decaying of dead tree parts returns nutrients to the
soil.
Flood Water Control - the root systems of trees hold in place soil that, if washed
away by heavy rains, would flow into streams and rivers, making them shallower and
allowing flood waters to overflow protective banks
Mineral and Nutrients Cycling and Retention - through growth, transpiration, and
death, trees tie up minerals and nutrients from the air, water, and soil
Climate Control - trees work as natural barriers to wind, snow, rain, and solar
rays to control climate in micro-areas
Habitat for Wildlife - trees and forests provide homes for many different species
of animals
Aesthetics - trees beautify urban and community areas such as parks, streets, and
schoolyards
Mental Health - trees provide green scenery that has been shown to speed up patient
recovery in hospitals and reduce employee stress
Physical Health - the forest is a great place to exercise, providing natural areas
for activities as hiking and backpacking
Recreation - the forest provides many resources for activities like hunting,
hiking, skiing, and bird watching
Natural Source of Medicines - trees provide substances with medicinal values such
as the active ingredients used in asthma medications and cough remedies
Education - forested areas offer many resources as outdoor classrooms
