Submerged aquatic vegetation and management options

Brittany Chesser, AgriLife Extension aquatic vegetation management program specialist and lead diagnostic scientist at AgriLife Extension’s Aquatic Diagnostics Laboratory, Bryan-College Station, will be the featured speaker of the hourlong webinar.

Chesser said submerged aquatic vegetation are rooted plants with most of their vegetative mass found below the water surface, although some portions may branch above water.

“We will cover how to identify common native and non-native species that can quickly take over small impoundments, including farm ponds,” Chesser said. “Once identified, we will briefly discuss their biology and how that plays a role in the pond’s ecosystem and management.”

Diverse management strategies, including mechanical, biological and chemical options will be discussed for each plant group or species.

Chesser said the webinar will also cover the importance of treatment timing based on changes in water temperature seen throughout the year.

A 30-minute question-and-answer session will be held at the end of the webinar.
