Wetland meadows are some of the most ecologically valuable environments on Earth. Instead of intrusive, traditional drainage management, wetland meadows can be embraced to foster biodiversity and sustainably treat water via phytoremediation.
2. To see the World in a Grain of Sand
And Heaven in a Wild Flower,
Hold Infinity in the palm of your hand
And Eternity in an hour
-William Blake,
Auguries of Innocence
3. WET MEADOW:
A type of marsh that
commonly occurs in poorly
drained areas such as
shallow lake basin, low-
lying farmland, and the land
between shallow marshes
and upland areas.
Supports incredible species
diversity and offers many
ecological benefits.
4. If there is magic
in the world,
it is contained in the
water.

• Expensive
• Does not treat water

9. Thriving Plant Diversity
PLANT COMMUNITY:
“A snapshot of [plants] growing together at a
certain point in time. Over the procession of
seasons, plants associate and disassociate
freely with one another.”
– Claudia West
Principal, Phyto Studio
10. Rather than ‘What a beautiful garden,’ I prefer to
evoke the response ‘What a beautiful place.’
-- Larry Weaner, Larry Weaner Landscape Associates
11. “This 54 acre site (former sod farm) is now home to
35 species of birds, 200+ species of moths and butterflies,
wood turtle and various reptiles and amphibians.
Wet meadows are super valuable.”
- William E. Young, CERP, PWS
Senior Ecologist
12. Ecological Services of Wet Meadows
Capacity for storm
water absorption
Reduces impact of
flood events
Prevents transport
of sediment
Provides erosion control
13. Phytoremediation
Phytoremediation is the direct use
of living green plants for in situ, or
in place, removal, degradation, or
containment of contaminants in
soils, sludges, sediments, surface
water and groundwater.
A low cost, solar energy driven
cleanup technique.
Most useful at sites with shallow,
low levels of contamination.
Useful for treating a wide variety
of environmental contaminants.
Effective with, or in some cases,
in place of mechanical cleanup
methods.

14. “The times when it was enough for plants to just look pretty are
over. In today’s post-wild reality, plants have to provide way more
than just beauty and color around a house.
Plants have to help us clean rain water and air, sequester carbon
in the soil, and clean up pollutants in our cities.
Modern planting design has become more complex and
meaningful because of phyto technologies – they open up a
hopeful and inspiring new chapter in the evolution of planting
design and help us improve our own lives.”

25. Best Management Practices
Possibilities With Purpose
Mow a path: encourage interaction!
Signage – public awareness & engagement
Environmental education
Observe often
Report results!
26. Benefits of Wet Meadows
• Satisfies LID (Low Impact Development) and
SSI (Sustainable Site Initiative) criteria
• Restores ecosystem services
• Response & adaptive management to climate

Notes de l'éditeur
Traditional remediation techniques include detention ponds and retention ponds. These are far more disruptive and less eco-beneficial than installing a bio-diverse and phytoremdiative wet meadow.
Detention Pond: Dug to temporarily store excess stormwater, controlling the flow so it drains (from the bottom) gradually at the pre-disturbance level.
Retention Pond: Permanent water holding pond, with drain at a specified height to control water level.
We can’t play Wackamole with species control!
“for most of the year, wet meadows are without standing water, though the high water table allows the soil to remain saturated. A variety of water-loving grasses, sedges, rushes, and wetland wildflowers proliferate in the highly fertile soil of wet meadows”
While seemingly occupying the same space, plant species adapt to live in unique environmental niches through:
varying root depths
light tolerance
hydric soil tolerance
microbial relationships for nitrogen fixing
Here is a wet meadow at Oxford Wetland mitigation bank in Oxford, NJ.
Enzymes in plant nectar, such as iridoid glycosides in Chelone glabra (Turtle head) offer a special benefit to bees – it helps relive bees with parasites. Researchers from the University of Vermont even found that bees will seek out flowers producing more of this enzyme-rich nectar when they are infected, more so than when they are uninfected. http://blogs.discovermagazine.com/inkfish/2015/09/01/parasitized-bees-may-self-medicate-with-nectar/#.WgPEPraZPy8
