Natural resource policy

What is meant by 'human dimension' of natural resources management? How people view their environment
Name two places in/near Tucson where the science of ecology has been formally presented since the early 1900s? ASDM & Santa Rita experimental ranch
Briefly describe the vision for the School of Natural Resources and the Environment. To provide innovative research and applications that lead to sustainable management of Natural Resource
What kind of real- world problems does the School of Natural Resources address? Wildfires, bufflegrass, invasion, droughts, population
What is ‘NEON’ and why is it relevant to the School of Natural Resources? National Ecological Observatory Network. It uses sensors to study climate change, land use, and invasive species.
What is the ‘Sun Corridor’ and where does it occur? Its a metropolitan area from Tucson to Maricopa County.
What are some steps one should take as an undergraduate in the School of Natural Resources to help ensure success in the “real world” after graduation? Talk to advisors, do field work
What is the ‘survival’ perspective and how did it shape our views on nature? Struggle for existence. Man against nature, so nature needed to be tamed.
What is meant by a ‘utilitarian’ perspective on the environment? Natural resources for food, water, and shelter.
What is "deferred gratification?" Store food, so you can utilize later.
What is an "anthropocentric" perspective? Human-centered world
What were some of the beliefs of Anglo-Europeans settling the New World that shaped how they (and we) viewed nature and the environment? Natural resources were a gift from the creator. Man has dominion over nature.
How has the Anglo-European concept of 'civilization' and 'progress'? Believed that they can modify the environment to suit their needs as a growing population
What is 'Manifest Destiny' and how does it relate to notions of 'civilization' and 'progress'? It means the rain follows the plow- if we plant crops, then God will give us rain.
Explain the belief that 'rain follows the plow' that was prevalent during the settlement of the New World. If we plant crops, God will give us rain.
What are some examples of 'impediments to civilization' and how do these relate to how people view nature? Trees, rivers, native peoples. It makes people think they can remove them whenever they want.
What is the thesis of the book 'Guns, Germs, and Steel'? How is it related to colonialism? We often disrupt the traditional systems of natural resource use. Colonists quested for natural resources but violated traditional methods.
How did capitalism and free enterprise influence our views toward nature? They believed that land could be bought and sold. It was a pattern of exploiting environments and finding new ones after,
What s the basic pattern of human-natural environment interactions that has been repeated over and over throughout history and around the world? Bountiful resources Human populations grow and expand Develop new technology Over-exploit environment Develop restrictive regulations Seek areas with bountiful resources---> Human pop grows..
What is meant by the 'next ridge syndrome' and how does it relate to early 'solutions' to environmental problems in the New World? Because of bountiful and seemingly inexhaustible resources, people felt that when they used up the resources in one area, then they could simply move to a new area
What is 'conservation' and why can it be difficult to agree on what constitutes it? Conservation: sensible, careful, and wise use of natural resources. What is sensible, careful, and wise??-- subjective words
Define maximum yield As much as we can get
Define sustainable yield Ecological yield that can be extracted w/o reducing the base 'capitol'
Define maximum sustained yield 'Managing on the edge'-- take as much as we can w/o reducing capitol
Which kind of yield should we do and why? We should shoot for sustainable yield that isn't at its maximum so we can factor in problems such as less rainfall

What are some challenges associated with preservation. How much land can be set aside and in what configuration.
What is ecology? Basic science dealing with relationships between organisms and their environment.
How is environmental science different from ecology. Environmental science- chemistry; studies the effects of pollutants on the environment while ecology- biology; studies all factors that affect the distribution and abundance of organisms

What is an 'environmentalist'? People concerned about our impact on environmental quality (ie air) and wasteful use of resources.
What are some distinctions between an environmentalist and an ecologist? Environmentalists are often NOT trained ecologists (usually socially motivated)
Should ecologists and natural resource scientists be environmentalists? Why They should be environmentalists since their work involves the environments so they should have that level of concern about the environment
What did the assigned article by Strong say about ecologists vs environmentalists? They should be environmentalists since their work involves the environments so they should be concerned about it.
What are some of the basic and applied sciences and what is the distinction between them? Basic science: Astronomy, Chem, Physics Applied science: Applying knowledge from one or more basic scientific fields to practical problems ie Wildlife Mnagement
What is Conservation Biology, when did it emerge, and what its unique perspective? Conservation Biology is the recognition of the importance of biological diversity. 60-70s Emphasizes intrinsic value of all forms of life, not just those with economic value.
Why is it important to consider ethics in addition to basic and applied sciences? We can know why we should conserve, to do the right thing that preserves the environment
What are the three major ethical perspective on natural resources Preservation Ethic Conservation Ethic Land ethic

What were some things going on in the Gilded Age? Economy grew 400% Technological Advances Titans of industry created monopolies Little government regulation
What is stewardship and how does it relate to natural resource conservation? Responsibility for taking good care of the resources entrusted to one
What is the first rule of intelligent tinkering? the first rule of intelligent tinkering it to keep all the pieces. So, if we loose ‘pieces’ of ecosystems, we risk the system loosing its function; and if the pieces lost cant be replaced, then the system wont function the same
What is implied by 'citizen-members', 'stewardship,' and 'husbandry' in Leopold's Land Ethic? Humans are not "above" any other organisms. We are just another piece and need to work together with every other component.

Why is it important for ecologists to be grounded in the basic science? Everything is connected- need to know about each specific part
Why would knowledge of ethology and sociobiology be potentially useful for an ecologist? Ethology is the study of behavior- so ecologists would need to know mating behaviors. Sociology would tell an ecologists about hers, packs..

What sorts of things do ecosystem scientists study? Characteristics of ecosystems- size, shape, boundaries
What is a biome? Regional ecosystem; characterized by distinctive plant formations, climates, and animals.
Is the biosphere an ecosystem? Why or why not? Yes; it's a global ecosystem that contains organisms interacting with their environment
Are ecosystem open or closed? Why? Ecosystems are open because other ecosystems outside of it affect it
How are the boundaries of ecosystems determined? Boundaries of ecosystems are determined by the observer
How does the concept of 'emergent properties' apply to ecosystems? Emergent properties apply to ecosystems because the whole is greater than the sum of parts. Some Interactions only happen when it as a whole
How does the concept of 'synergism' apply to ecosystems? All components of an ecosystem work to produce an effect greater than their individual efforts. Things that happen when all the components interact ex: alchol and pills together . Separate, they have different effects
