    Native plants

    Key to the water quality treatment functions of natural treatment systems (NTS) is the capacity of native wetland plants to filter and absorb nutrients. Vast plantings of emergent and open water wetland species along with native trees and shrubs add species and structural diversity. See how plants support our treatment as water is transferred to the atmosphere by evaporation and from the soil and other surfaces and by transpiration from plants. Below are species you'll see along the trails and in the Water Garden as well as in the NTS.
