Course Overview • Course website: www.hydrology.uga.edu/mckay/8980.htm

• Course Objective: Become familiar with the general context of the $1B / year stream

restoration industry. – Overview of stream restoration – Alternative disciplinary viewpoints – Key restoration techniques and methods

• Course Format

– Read papers each week on a focal subject in river restoration – Short lecture on the subject (i.e., less than 15 minutes) – Paper discussion

• A few notes: – The course doesn’t succeed without your engagement and discussion. – The schedule and reading assignments are a proposal. Feel free to suggest alternatives!

• Responsibilities and Expectations

– 60% - Read all assigned papers and participate actively in discussions. – 20% - Lead discussion on a minimum of 4 papers over the course of the semester (groups welcome). – 20% - Writing assignment

Writing Assignment

• 500-2,000 word non-traditional writing assignment.

• Open to ideas on format and content – A short position paper on topics such as: success or failure of

mitigation, socio-economic v. ecological motivations, or novel funding mechanisms for restoration.

– A letter to an elected official. – A book review in the style of a peer-reviewed journal. – An opinion-editorial (op-ed) for an appropriate popular press outlet. – A published discussion of a journal article on stream restoration. – A detailed case study report on the success (or failure) of an

ecosystem restoration project or state/regional/national program.

Topic 1: Ecological and societal demands for freshwater

• Global demand for freshwater

– Spreadsheet: Household water use

• Freshwater biodiversity (crisis)

– Video: The last dragons

– Map: That State of the World’s Rivers

Human demand for freshwater

• Municipal use

• Industrial use

• Agriculture

• Energy

• Navigation

Figures: USGS (2009), Plant Vogtle (Glynn Environmental)

• Waste assimilation

• Recreation

• Aesthetic

• Cultural

• …

Global freshwater supply

• 54% of accessible runoff is in use (Postel et al. 1996)!

• Consumptive v. Non-consumptive use

Water management infrastructure

• Withdrawals & canals

• Dams, reservoirs, and ponds (next slide)

• Levees

• Groundwater pumps

Land of 10,000 lakes reservoirs

Household water use

• How do we use freshwater at home?

• Where does freshwater in Athens come from?

• How much water do you use?

Freshwater Biodiversity

• Rivers, lakes and wetlands are unbelievably speciose

• Highly endemic species

Eukaryotes Vertebrates

Strayer and Dugeon (2010, JNABS)

Bars = Described Species Lines = Imperiled Species

Biodiversity Hotspots

Georgia’s freshwater biodiversity

• More than 325 species of fish occur primarily in the freshwaters of Georgia, including 8 federally listed species, 57 state listed species, and at least 8 endemic species.

– Colorado River Basin has 25 species of fish.

– Columbia River Basin has 33 species of fish.

– Etowah River Basin has 76 species of fish.

Biodiversity Crisis

Strayer and Dugeon (2010, JNABS)

What is causing these declines?

– What patterns do you find most striking?

– Do any of the data surprise you?

– Do any specific watersheds catch your eye?

Next week

• What is “restoration”? – What is the purpose of restoration? – Ecosystem structure v. function v. services? – Restoration for the sake of people or ecosystems

• Reading assignments
