With the approval and cooperation of GCBO, the Texas Coastal Watershed Program (TCWP) has opened a wetland plant nursery in the southern portion of the GCBO property. Currently, four shallow above-ground ponds and other propagation areas have been created. The main objective is to create portable potted specimens of local ecotypes of native wetland plants, many species of which are not available from other sources, for use in local projects of wetland restoration and creation of engineered storm water retention ponds.
An “engineered” storm water retention pond is one in which deeper sections are created to hold water between rains, while also creating large shallow areas (shelves) along its banks for dense planting of wetland plants. This creates both a small wetland habitat for local wildlife and recreation for local residents, in addition to its role to hold excessive rainwater runoff in emergency situations. The wetland plants are useful in improving the runoff water quality by minimizing the impact of sediment and pollution on local bodies of water.
Notable holdings at the TCWP nursery include:
- several species of “Louisiana Iris” native in Brazoria Co. (brevicaulis, giganticacerulea, hexagona),
- local ecotypes of Hibiscus (laevis, lasiocarpos, moschuetos, striatus),
- Spider Lily (Hymenocallis liriosme) and Swamp Lily (Crinum americanum),
- and uncommon species such as Indianola Beaksedge (Rhynchospora indianolensis) and Buttonbush Flatsedge (Cyperus cephalanthus).
