Bio Diversity Defined
• 1) Bio diversity is the variety of

• 2) It can be likened to the fabric
of life ––thousands of
individual threads woven into a
complex tapestry across the
landscape. *
*Oregon Bio Diversity Project
Why is bio diversity
important to conserve?
• Bio diversity is central to our
quality of life. It supports
natural resource industries that
produce commodities such as
fiber, fuel, food, and medicine,
as well as recreational uses.*
*Oregon Bio Diversity Project
Why is bio diversity
important to conserve?
• Bio diversity includes healthy
functioning ecosystems, which
provide essential ecological
services such as water
purification, flood control, and
nutrient recycling.*
*Oregon Bio Diversity Project
Why why be concerned
about invasive species?
• Invasive species move into a
eco niche, establish and remove
the natural balance of the
ecosystem.
• In essence altering the natural
food web of that ecosystem.
