1 Forestry and Resource Management Lesson 1: Resource Management

2 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

3 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

4 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 ________

5 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.

6 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

7 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

8 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

9 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

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

11 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

12 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?

13 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

14 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

15 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

16 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  gallons of water to make a new car  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.) SectorPercentUse/Person/Day Domestic (home)/Commercial gallons Industrial/mining gallons Thermoelectric power gallons Agriculture gallons

17 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.

18 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 adults left  Northern slopes of Volcan Wolf  More vulnerable to natural threats  Invasive species prevention and breeding program in place

19 Timber  What is timber?  “Your National Forests” Inquiry Activity  Continue on this activity today – finish for homework for Wednesday (9/10)

20 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

21 Timber   Deforestation & Habitat Fragmentation  “Your National Forests” Inquiry Activity  Continue on this activity today – finish for homework for Wednesday (9/10)
