→Hydric Zone Criteria
| Often referred to as upland area. The ecology of this zone is terrestrial due to its elevation in relation to the filter bed. The zone most closely resembles a Cultural Meadow or a Cultural Thicket community, depending on the mix of grasses, herbaceous material, shrubs and trees utilized.

'''Low Zone'''
*Mineral Meadow Marsh plant community
*Grasses, Sedges, rushes, wildflowers, ferns and shrubs that have an ‘Obligate’ to ‘Facultative’ designation
*Wetland ‘Obligate’ species that are flood tolerant as they will persist in average years and flourish in wetter years.
*Plants that are likely to occur in wetlands or adjacent to wetlands.
*Plants with dense root structure and /or vegetative cover are favoured for their ability to act as pollution filters and tendency to slow water velocity
*Be advised these practices are not constructed wetlands and are designed to fully drain within 48 hours.
'''Mid Zone'''
*Plants able to survive in soils that are seasonally saturated, yet can also tolerate periodic drought.
*Species include grasses and groundcovers, as well as low shrub species.
'''High Zone'''
*Plants should have deep roots for structure, be drought-tolerant and capable of withstanding occasional soil saturation.
*Trees and large shrubs planted in this zone will aid in the infiltration and absorption of stormwater.
*This area can be considered a transition area into other landscape or site areas.
*A variety (min. five) species should be used to prevent a monoculture.
