Protect Our Ponds: A community‐based social marketing task force to
improve water quality
Outline1. Urban stormwater and water quality in
Florida
2. Backyard stormwater ponds as environmental and landscape feature.
3. The barriers to changing behaviors; research results
4. Potential solutions created through community engagement.

Improvements in Water Quality in Tampa Bay
The challenge of controlling nutrients from stormwater runoff
Floridians apply 35 million pounds of nitrogen to their yards every year

Nutrient pollution in Florida waterways
Can nutrient runoff feed red tide outbreaks?
Removing nutrients from stormwater is expensive
Several baffle boxes have been installed through Martin County to filter runoff water. Workers here install the concrete lid of a baffle box. Officials hope a stricter fertilizing ban could eventually reduce the need for these efforts.

Controlling Fertilizer runoff is key to water quality efforts
Best practices recommend not fertilizing before heavy rain
Summer fertilizer blackout periods

A social marketing approach to changing nutrient management
Steps:
1. Work with partners in the community
2. Conduct research on the behaviors, benefits and barriers to change
3. Collaboratively decide on solutions
4. Focus on specific audiences
5. Focus on specific behaviors, lower barriers,
promote benefits
5. Implement and evaluate
Closer to Home:Fertilizer and nuisance algae
The ideal perception of the pond

What contributes to the problem?• Design of stormwater systems (everyone connected)
• Landscaping dominated by turf
• HOA rules that encourage intensive watering and fertilizing of turf
• Landscaping on ponds that makes natural function difficult
• Homeowner preference for one kind of landscape
• Homeowner knowledge about the connection between fertilizer and algae growth is limited
• Maintenance practices cause additional problems
The stormwater system links all of the yards in the neighborhood
Aesthetic preferences are at odds with environmental function

The fertilizer/algae connection
Grass clippings in the ponds contribute to nutrient pollution
What behaviors need to change?
1. Follow the summer fertilizer blackout to reduce runoff
2. Control grass clippings (in street and ponds)
3. Install buffer zone around ponds
4. Increase aquatic plants to take up nutrients

Survey Findings
• 44% of respondents (on‐pond n = 429 & off‐pond n = 268) did not know landscapers in Manatee County are required to be certified
• 24% have talked to their landscapers about keeping fertilizer away from sidewalks, curbs, and ponds
• 12% have talked to their landscapers about keeping grass clippings out of stormwater drains and ponds
Survey Findings
• Residents who have talked with their landscapers about keeping fertilizer or grass clippings out of stormwater drains and ponds tend to be those who knew that landscapers in Manatee County must be certified
• No other variable (such as age, gender, income, ethnicity, or environmental attitude score) was significantly associated with the likelihood of talking with a landscaper about these issues
Benefits of planted buffer around ponds
• Absorb nutrients
• Prevents fertilizer from directly entering the pond
• Littoral plants pump oxygen into water and create habitats
• Control nuisance vegetation
• Provide shoreline habitat

Shoreline and aquatic plants are a major change
Research findingsCultural/Social Norms
•Value interaction with neighbors (care what the neighbors think)• Appreciation for HOA restrictions, the controlled/consistent environment fits in with neighborhood aesthetics• Pride of ownership‐ manicured look and upkeep• Pride in neighborhood and community• Wildlife highly valued
Perceptions of algae problem in their backyard ponds
• “Cruddy”, “swampish”, “scummy”, “ a health issue”
• “We’ve had social gatherings at the house and people have made comments… what’s up with your swamp out there”
• ..the smell off of those lakes will take your breath away.

Summarizing research on barriers to shoreline buffers
• Neighbors won’t like it
• Blocks view of the water
• Plants will get out of control
• Cost of maintenance
• Unwanted wildlife

Engaging stakeholders in solutionsProtect Our Ponds Science Cafe
Walkabout educational activities
Neighbors have to agree to collaborate

Solutions must use a combination of approaches
1. Government mandates that target behavior2. Education about stormwater and landscape
connection is one step3. Technological solutions combined with community
engagement4. Improving performance of ponds through
landscaping (buffer planting, littoral and aquatic) 5. Controlling nutrients at the source through
behavior change6. Recognize that the cultural practices of turf grass
management is greatest barrier to behavior change
