Wetland Monitoring – Anderson Lake
A private landowner contracted NES to monitor the success of a wetland restoration on their property. We permanently marked sites with a handheld GeoXH Trimble GPS unit to facilitate collection of comparable data in the future, and to allow analysis of temporal trends.Observed native species included multiple floating-leaved aquatics, submerged aquatics and emergent vegetation. Since the monitoring began in 2006, invasive and exotic species within the restored area have decreased. Red top (Agrostis stolonifera), Canada thistle (Cirsium arvense), curly dock (Rumex crispus), and dandelion (Taraxacum officiale) observed in 2006 are no longer present.
NES was also responsible for the removal and/or treatment of non-native species when and if they were found within the restored wetland.
Observed native species included multiple floating-leaved aquatics, submerged aquatics and emergent vegetation. Dominant vegetation includes:
- American white water-lily (Nymphaea odorata)
- Various pondweeds (Potamogeton spp.)
- Broad-leaved arrowhead (Sagittaria latifolia)
- Broad-leaved cattail (Typha latifolia)
Dominant species on the north end of the restoration includes:
- Common tussock sedge (Carex stricta)
- Marsh fern (Thelypteris palustris)
- American bur-reed (Sparganium americanum)
- Pussy willow (Salix discolor)
- Swamp rose (Rosa palustris)
- Meadow-sweet (Spirea alba)
