1. DO NOW: Group the EGS listed below into the proper category (provisional, cultural, regulating)
Purification of air & water
Preservation of soil
Prevention of floods & droughts
Regulation of climate
Maintenance of biodiversity
Cycling of nutrients
Detoxification & decomposition of waste
Aesthetic beauty
Dispersal of seeds
Moderating weather extremes
Protecting people from UV rays
Control agricultural pests
Renew soil fertility
Regulate disease carrying organisms
Pollinate crops & natural vegetation

2. Valuing Ecosystem Goods & Services
Objectives:
Identify & discuss monetary & non-monetary methods of valuing EGS
Understand the importance of both valuation methods

3. Think about the task
Today’s task
What non-monetary measures can be used to value goods and services provided by this ecosystem?
What will I learn?
the value of EGS can be quantified using monetary and non- monetary methods
why it might be important to use non-monetary methods to quantify the value of EGS

4. Explore the idea
The value of different transportation options can be compared using monetary measures such as cost.
Are there other ways to quantify and measure their benefits?

6. Much like quantifying and measuring the non-monetary benefits of a transportation choice, non-monetary measures can also be used to determine the value of EGS.

8. Why might it be important to use non-monetary methods to quantify the value of EGS?
Are there benefits of EGS that non-monetary methods can measure that monetary methods cannot?
Are there situations where non-monetary measures might be more effective or appropriate than monetary measures?

9. What are ecosystem services worth?...
Much of the Mississippi River Valley’s flood protection services were destroyed when adjacent wetlands were drained and channels altered. As a result, in 1993 floods resulted in damages estimated at $12 BILLION, partially from the inability of the Valley to lessen the impacts of the high volumes of water.
Over 100,000 different animal species -- including bats, bees, flies, moths, beetles, birds & butterflies – provide free pollination services. One-third of human food comes from plants pollinated by wild pollinators. The value of pollination services in the U.S. alone is estimated at $4 – 6 BILLION per year.

10. What are ecosystem services worth?...
80% of the world’s population relies on natural medicinal products. Of the top 150 prescription drugs in the US, 118 originate from natural sources: 74% from plants, 18% from fungi, 5% from bacteria, and 3% from one snake species.

11. Exit ticket:
Why is it important to consider the non-monetary value of EGS?
Give an example of a situation where a non-monetary method might be more effective or appropriate to use than an monetary method in valuing EGS.
