Forestry and Resource

ManagementLesson 1: Resource Management

Renewable Resources

A resource that is replenished, or renewed over ______ periods of time

Examples include: _________ _________ _________ _________

A renewable resource can become nonrenewable if extracted more ________ than being replaced

Renewable Resources

A resource that is replenished, or renewed over short periods of time

Examples include: Soil Freshwater Wild Animals Timber

A renewable resource can become nonrenewable if extracted more quickly than being replaced

Nonrenewable Resources

A resource that is formed much more _________ than it is used

Examples include: Fossil fuels such as ______, _______

___, and ________ ____

Once nonrenewable resources are completely depleted, or used up, they are gone ________

Nonrenewable Resources

A resource that is formed much more slowly than it is used

Examples include: Fossil fuels such as coal, crude oil,

and natural gas

Once nonrenewable resources are completely depleted, or used up, they are gone forever.

Sustainability

A resource is considered sustainable if it can continue at the ______ rate into the foreseeable future

In recent years, consumption of natural resources has _________ to unsustainable levels, driven by the growth of the ______ human population in history

Sustainability

A resource is considered sustainable if it can continue at the same rate into the foreseeable future

In recent years, consumption of natural resources has increased to unsustainable levels, driven by the growth of the largest human population in history

Resource Management

Managing of resource harvesting so that resources are not ________

All natural resources, both renewable and nonrenewable, serve functions in their ____________, so we must harvest them ____________ in order to maintain the health of those ecosystems

Resource Management

Managing of resource harvesting so that resources are not depleted

All natural resources, both renewable and nonrenewable, serve functions in their ecosystems, so we must harvest them sustainably in order to maintain the health of those ecosystems

Soil

Webquest: How is soil formed? What is it used for? What happens if topsoil is overused?

Soil

Always being made by natural processes such as the weathering and erosion of rocks and the decomposition of organisms Top layer, or topsoil, is made very slowly

One inch can take hundreds of years to form

Needed to nourish plants (crops, forests, other plant communities)

Soil degradation – Any undesirable change or disturbance to the soil

Desertification – degradation of dryland ecosystems can lead to formation of deserts – unsustainable farming practices near deserts

Fresh Water

Webquest: Where does it come from?

Globally? Locally?

What is freshwater used for? What is most of it used for in U.S.?

What are some issues associated with water management?

Fresh Water

3% of water on earth is freshwater

2.4% is permanently frozen in glaciers and at the polar ice caps

0.5% is ground water

1% is in rivers and lakes (surface water)

KS, MO – Missouri River

Water in KC – clean, used, cleaned again

Early Days: from cisterns and wells – waterborne illnesses, no fire protection

1874 – city’s first waterworks – 5 million gallons of drinkable water per day from the Kaw River

Today – Kansas City Water Services – 240 million gallons of water each day from the Missouri River 2,800 miles of water mains/pipes Test 60 samples a day for over 300

contaminants

Water in the U.S. Many cities’ water supplies are

from outside sources – water diversion and reservoirs

Dams store water (irrigation, drinking, home use, generating electricity, industry), but can alter scenic area, displace people, and alter natural wildlife habitats (disrupts fish migrations and alters water’s temperature and oxygen content)

Water supplies are shrinking and pollution is increasing

Water Use Average American home, each person uses about 80 gallons of water

per day (75% of which is used in the bathroom; 22% washer)

4 gallons of drinking water for a dairy cow = one gallon of milk 39090 gallons of water to make a new car 62600 gallons to produce one ton of steel 300 million gallons to produce single day’s supply of US newsprint Water Issues – availability of freshwater (pollution, overuse, habitat

reconstruction, fish breeding patterns, etc.)

Sector Percent Use/Person/Day

Domestic (home)/Commercial

11.5 155 gallons

Industrial/mining 8.2 110 gallons

Thermoelectric power 38.6 518 gallons

Agriculture 41.7 558 gallons

Wild Animals

Why are animals hunted?

What contributes to decline of animal populations?

What is the difference between hunting and poaching?

Research one animal that is threated or endangered and tell use where it is, what the population numbers are like, and what contributes to its decline.

Wild Animals

Use Food Population control Products (furs, medicines, etc.)

Decline Habitat loss Hunting Poaching – illegal hunting Pollution By-catch

Endangered species (IUCN Website) Galapagos Pink Land Iguana Critically Endangered Endemic to Isla Isabela Single population - 200 adults left Northern slopes of Volcan Wolf More vulnerable to natural threats Invasive species prevention and breeding program in

place

Timber

What is timber?

Timber

Wood from trees, or timber, is the raw material for an amazing variety of products you need every day Forests in developed nations are

slowly regrowing due to better forestry management

Forests in developing nations, however, including rain forests, are disappearing at an alarming rate

Overall more forests are lost than regrow
