Trees can attract wildlife to an area and help bring
a biodiversity of animals to our community.
Areas planted with many trees and plants have proven
useful in phytoremediation or bioremediation, which is
the removal of toxic materials from soil.
Trees can become living witnesses to our history and
evidence of our cultures. Without a cultural history,
people are rootless. Preserving historical trees offers
lingering evidence to remind people of what they once
were, who they are, what they are and where they are. It
feeds our sense of history and purpose. As an example,
the trees in Dealy Plaza that witnessed the
assassination of President Kennedy. There are over
100,000 people that visit the site each year as a
result. The trees in the plaza are considered historic
due to the significant event that they witnessed.
Trees are a source of food for humans. Pecans,
walnuts, and almonds are only a few of the foods we get
from trees. On a large scale, food-producing trees
require less fertilizer and keep the soil healthier than
any other crop.
Trees can screen objectionable views, offer privacy,
reduce glare and light reflection, offer a sound
barrier, and help guide wind direction and speed.
Trees add beauty to our city by creating a background, framing a view, complementing architecture, and bringing natural elements into urban surroundings.
Trees provide unlimited climbing challenges and fun physical activities like using tree swings and playing in tree houses.
Bioremediation: the use of biological agents, such as bacteria or plants, to remove or neutralize contaminants in polluted soil or water.
