GROSSE POINTE FARMS — The fight against phragmites near Pier Park resumes this fall.
“It’s constant vigilance, something we’re probably going to have to do on a regular basis for many years,” said Shane Reeside, Grosse Pointe Farms manager.
He signed another contract last month with Environmental Consulting and Technology to oversee more counterattacks on invasive phragmites rooted in accretion about 1/4 mile along the Lake St. Clair shoreline above the park.
“They’re going to negotiate and oversee another herbicide application scheduled no later than Oct. 15,” said Councilman Lev Wood. “The herbicide is not broadcast. It’s done using sprayers. It’s very specific to the plants.”
Total cost for this stage of work is $3,250, Wood said.
“It’s an ongoing thing,” he added.
ECT is the city’s consultant on eradicating phragmites.
The company’s licensed employees coordinated chemical treatments starting two summer ago.
A controlled burn last May generated 10-foot flames and forced temporary closure of Lakeshore between Moross and Provencal.
“We did a decent job of knocking down phragmites this year,” Wood said. “They’re not eradicated by any means. It’s a long-term process.”
“This is sometimes a multi-year process to get rid of phragmites,” Reeside said. “But, they have been confined more than before. Some areas are phragmites free.”
Future applications may be done in-house at lower cost by a licensed public works employee.
