Ecology of Stormwater Ponds
Presenter
Presentation Notes
Important Functions – Capture of stormwater runoff and pollutants from urban landscapes SWP effects on adjacent forested wetlands / drainage easements SWP effects on invasion Effects plants on water quality Effects of plant community management on invertebrate communities
> 95,000 in Florida!
Overlap with Stakeholder Needs
• Stormwater management• Water conservation• Water quality
• Opportunities to increase biodiversity & ecosystem services in urban landscapes
Other functions / Ecosystem services
UF SEEP
Plants contribute to services
UF SEEP
Enhancing pond functions via ornamental plantings
Issue: Were chosen plant species contributing to intended goals of the planting?
Or chosen for aesthetics & availability
Firecracker plant (Russelia equisetiformis)
Virginia sweetspire(Itea virginica)
Need: A tool to guide trait-based selection of plants

Traits database: Information
Traits database: Download
• Commercially available• 78 Species are native• Exotics are non-invasive (UF|IFAS Assessment)
• Traits database: 82 Plant species
• Trait Categories
(1) Aesthetics – Plant species’ appearance
(2) Function – Species’ impacts and responses to environment
(3) Habitat – The conditions under which the species grows best
Traits database: 31 Traits

Some considerations
Importance of Trait Diversity
• e.g. Variation in habitat needs
Nealis 2015
Trait diversity can enhance pond functionality
Presenter
Presentation Notes
12 ponds in LWR 27 variables associated with pond characteristics and landscape setting Vendiagram showing: Factors that affect the different nutrient pollutants
Nealis 2015
Trait diversity can enhance pond functionality
Presenter
Presentation Notes
Need a combination of plants types to maximize removal and limit algae growth
Benefit of multispecies plantings
• Functional redundancy Ecosystem stability
• e.g. Stable / long-term erosion control
Future Direction
• Add new species
• Include new traits
• Find missing information
• We need feedback!
