In Notebook:
What is the difference between an
invasive species and a non-native
species?
** If you were absent Friday please let me know as I stamp
your notebook - I have a sheet for you to fill out ASAP **

Conservation Funding Activity
Heads Up: (GRADED) Quiz on Wednesday!
IF YOU HAVE NOT TAKEN THE TEST OR TURNED IN
PREDATOR PREY LAB… DO SO ASAP!
Conservation Funding
Activity
You are a part of a committee for an
Environmental Organization, GCEAO (granite
City Environmental Action Organization). The
GCEAO has $20,000 dollars to allot to
environmental programs. Groups have submitted
their applications to receive your money. It is
YOUR job to determine how the $20,000 should
be spent.
Conservation Funding
Activity: Step 1
•
INDIVIDUALLY fill out the table with your “ranking”
•
1 = NOT IMPORTANT TO ME
•
5 = SUPER IMPORTANT TO ME
•
then determine where to spend your $20,000 and fill out
“Funding? Reason”
** You will likely need a spare sheet of paper and a
calculator for math (you may use your phone) **
Conservation Funding
Activity: Step 2
Come to a group agreement on which programs to
fund.
•
•
•
Circle this program name on your sheet!
Answer the questions INDIVIDUALLY.
Expectation: Everyone should be involved… each
group will be sharing their discussion with the class.
Conservation Funding
Activity: Step 3:
•
Pick a representative from your group to share
with the class:
•
The organizations you decided to fund
•
How hard/easy it was to reach an agreement

Why conserve?
•
A growing human population means a growing need
for natural resources
•
•
Natural Resources - materials and organisms
found in the biosphere
Developed countries use more resources than
developing countries
Natural Resources
•
•
•
Renewable Resources resources that are
replaced by natural
processes faster than
consumed
Examples: solar energy,
clean water, clean air,
agricultural plants,
species
Supply vs. Demand
•
Non-Renewable resources found on
Earth in limited
amounts that are
replaced naturally over
LONG periods of time
•
Examples: fossil fuels,
mineral deposits
Sustainable Use
•
Using resources at a rate which they can be
replaced/recycled while preserving the long-term
environmental health of the biosphere
•
Reduce amount of resources being consumed.
Recycle resources that can be recycled. Preserving
ecosystems.
How do we conserve biodiversity?
GOAL: Protect areas where biodiversity can flourish!
• Protect Specific Areas:
– National Parks - 1st park was Yellowstone National Park (1872)
– State Parks
– International Protected areas
• Large reserves protected by buffer zone (area only for sustainable
use of resources)
• Legally Protect
• Endangered Species Act (1973) - legally protects species becoming
extinct
• Convention on International Trade in Endangered Species of Wild
Fauna and Flaura (CITES) (1975) - outlawed trade of endangered
species and animal parts
Relevant Example:
•
Microbeads - plastic found in
cleansers end up in the water in
lakes
•
Trying to pass a ban on
microbeads!
Biodiversity Hot Spots
•
2 criteria for a region:
•
at least 1500 species of ENDEMIC
vascular plants
•
•
Endemic species - species that
are only found in a specific
geographic area
region must have lost at least 70% of
its original habitat
Check-In:
•
The red areas highlight the 34 biodiversity hot
spots… according to notes today what are we likely
to see in affect in those areas?
Ways to conserve biodiversity
•
Corridors
•
Pros: improve survival of biodiversity,
allows organisms to move safely from one
area to another
•
Cons: easily passes disease
What if biodiversity is destroyed?
•
When an area can no
longer provide the
abiotic and biotic
factors for a healthy
ecosystem . . . time to
restore it!
•
Determining factors for
recovery time:
•
size of area
affected
•
type of disturbance
How can we help restore ecosystems?
•
2 methods to help the recovery time:
•
bioremediation - using living organisms to detoxify an
area
•
Example: 80,000 gallons of kerosene-based jet
fuel leaked on SC beach & contaminated water
table. Scientists added nutrients to the soil so that
microorganisms broke down the fuels faster
•
biological augmentation - adding natural
predators to a degraded ecosystem
•
Example: Farmers use ladybugs to control
the Aphid population (aphids eat plants and
transmit diseases)
