The work is a follow-up to treatment that occurred in late 2011 to kill the invasive plant.
“We’re coming back through and knocking down all the dead thatch just to improve visibility to give park visitors a better area to see so they can observe wildlife and any other native plants that might be around,” Austin Boersema of Cardno-JFNew said.
Boersema was on Harbor Island driving an Argo amphibious all-terrain vehicle that crushed the invasive plant.
The work will allow the dead stalks to decompose faster, allowing sunlight to reach the soil and encourage growth of new wetland plants.
“It helps it decompose and gets it down in the water and the mud,” Boersema said. “It speeds up decomposition — and if there are some plants that come back, it makes it easier for us to re-treat if necessary.”
