2. Introduction and Literature Review (25 points)Due 07 March 2005 (deadline extended to 09 March 2005)
Now is your opportunity to explain in detail the environmental implications of the topic you have chosen. In a 5-7 page paper, you should explain the following:
•What are the ramifications of the current issue continuing on its course?•What does the literature say about the effects of this issue?•What are the biological, ecosystem, and economic costs and benefits associated with the issue?•Have there been other studies or solutions related to the problem you are addressing? What success stories can you draw from in creating a solution? •Tables and graphs of costs, benefits, effects on the environment, etc. are a useful addition here and are also very useful in the oral presentation.•Describe how the changes you recommend fit into the bigger picture. Where do the resources involved come from? Who is impacted? What costs are associated? For example, if I were recommending the University purchase vegetables from a local grower, instead of an international conglomerate, whose jobs would be impacted? How much more fossil fuel is burnt shipping from far away as opposed to from close to Tucson, etc.
Your literature cited section should include at least 10 sources. At least half of these should be from peer-reviewed and/or primary literature. Use the parenthetical citation format of Conservation Biology, which you can find by looking up this journal online (the citation format in your syllabus is very similar as well).
These websites can help you understand what meant by primary and peer-reviewed literature:http://www.lib.ecu.edu/Reference/workshop/primary.htmlhttp://www.bergen.cc.nj.us/Library/userguide/IV_A_prim_sec.htmlhttp://www.usd.edu/lhsl/ref/PublicationProcess.pdfhttp://www.library.jcu.edu.au/LibraryGuides/primsrcs.shtml
Saturday, March 05, 2005 -10 am - 4 pm
Researchers from the University of Arizona and community volunteers will unite on Saturday, March 5 to fight a foreign invader. The goal is to save Tumamoc Hill from buffelgrass.
Buffelgrass - brought here from Africa for cattle forage - has the potential to be the most destructive plant pest known in the Sonoran Desert, says Desert Lab researcher Travis Bean. Tumamoc Hill is overrun with buffelgrass, which not only out-competes native plants for water and soil nutrients, but increases the risk of brush fires to dangerous levels through increased fuel loads. Infestations create a grass-fire cycle that transforms picturesque saguaro landscapes into buffelgrass monocultures.
Tumamoc Hill on Tucson's west side is home to the historic Desert Laboratory and an 860-acre nature preserve. For more than 100 years the Desert Lab has been dedicated to studying plants, animals and the environment of North American deserts.
The mission of the Desert Lab has become even more important in recent years. Expanding populations in the Southwest have increased the stress on natural environments that surround its growing cities.
On eradication day, researchers will show how to recognize buffelgrass, and demonstrate approved techniques to remove it, including rock picks and herbicides.
The event is Saturday, March 5, 10 a.m. to 4 p.m. Parking is available at nearby St. Mary's Hospital. Winter in Tucson still means plenty of sunshine most days, so wear protective clothing, including sunscreen, a hat and gloves, and sturdy shoes to navigate the rugged hillside.
For more information, or to volunteer with the eradication project, call Travis Bean at the Desert Lab at 629-9455, or e-mail.

5-303 (R7-4-102) Prohibited ConductThe following misconduct is subject to disciplinary action: All forms of student academic dishonesty, including cheating, fabrication, facilitating academic dishonesty and plagiarism.
5-304(R7-4-103) SanctionsB.One or more of the following sanctions may be imposed for violation of the disciplinary regulations set forth in Section 5-303(R7-4-102): EXPULSION: Permanent separation of the person from the university. As applied to faculty and other university employees, expulsion may involve dismissal and termination of employment or non-renewal of an employment contract. An indication of expulsion will appear on the student's transcript or be maintained in the permanent file of the university employee. The person will also be barred from the university campus. SUSPENSION: Separation of the person from the university for a specified period of time. Permanent notification may appear on the student's transcript or in the file of the university employee. Except where any administrative decision under this Code indicates otherwise, a person suspended under this Code shall not participate in any university sponsored activity, may be barred from the university campus, and where such person is a faculty member or other university employee, any suspension shall be without pay or other benefits incidental to the person's employment position. PROBATION: This sanction shall be applicable to students only and may include forfeiture of campus privileges for a definite period of time. Additional restrictions or conditions may also be imposed. Appropriate university officials shall be notified of the imposition of such sanctions.

Biological Basis of the Sonoran Desert Conservation Plan
Thanks to Bob Steidl and others… 14
SDCP Biological Goal
Ensure the long-term survival of the full spectrum of plants and animals that are indigenous to Pima County…
15
Approach
• Select elements for planning• Establish quantifiable goals• Develop explicit rules for reserve design
process• Organize, synthesize, and acquire
information• Evaluate• Establish, Monitor, Manage
16
Planning Alternatives
• Biotic elements– Vertebrates– Vegetation communities
• Abiotic elements– Land cover, land form, elevation, aspect, etc.
• Unique elements
17
Select Species
• Regionally “vulnerable” species
• Short-list of 55 species
Species chosen should have little influence on ultimate reserve design
18
Species List• 9 mammals 7 bats• 8 birds 6 riparian• 7 reptiles 3 riparian• 2 frogs all riparian• 6 fish all riparian• 16 invertebrates mostly snails• 7 plants 2 riparian
>60% of plants and vertebrates associated with riparian environments

Species Information• Natural history accounts• Species-environment matrix• Decide best method by which to achieve
goals for each species• Less helpful if:
– either rare or common– on lands that are protected or off-limits– limited natural-history information
• Reduced from 55 to 44 species20
Land Cover
• Vegetation communities• Abiotic / physical• Urban, suburban, rural land-uses• Ownership and level of protection• Threats

Species Distributions
• Based on models rather than known locations or published distributions
• Developed to predict species distributions based on potential habitat
• Input and evaluation by experts– Habitat associations, known distribution
• Iterate• Combine to identify areas of high species
