Research Questions

1. How do wetlands respond to water policies and the urban growth that those policies facilitate?

2. How do perceptions and values of change in freshwater habitats vary?

3. How do relationships among jurisdictions and stakeholders result in particular water policies?

Key informant interviews, focus groups, resident interviews & public meeting observationp g

• Semi-structured interviews with key informants- Regulators and managersRegulators and managers- Politicians- Business and development interests- Citizen and landowner interest groupsCitizen and landowner interest groups- Environmental advocacy groups

• Focus groups- Recruited residents with professed interest- Open-ended discussions on key topics help refine

subsequent resident interviewsq- Discovered stakeholders in resource conflict areas

• Public meetings: note topic, who turns up and what they say

• Structured resident interviews (orally administered surveys in homes, businesses, coffee shops)

Preliminary findings from focus groupsfrom focus groups

• Many residents feel strongly about destruction of wetlands, lakes and

R T k Rd

destruction of wetlands, lakes and other freshwater resources that have been directly affected by groundwater pumping

Race Track Rd•Directly affected residents have a good understanding of the water distribution system and its effects on local wetlands and aquifer

•D l d liti l i t t•Developers and political interests often blamed for influencing problems more than utility and governmental agencies responsible

Resident interviews

• Do residents near impacted areas have greater understanding of water distribution,greater understanding of water distribution, equity, and environmental impact?– What do resident in study area know about change in waterWhat do resident in study area know about change in water

resources, particularly wetlands? – Who do they hold most responsible for these changes, and

h ?why? – What do residents view as the “drivers” of change in

wetlands?wetlands? – How do these views affect their participation in public

meetings about water?
