Lake George Kills 97% of Invasive Clams with Mats

Lake George in New York has successfully eliminated 97% of invasive Asian clams in a five-acre area using a large-scale benthic barrier treatment.

The treatment, which involved covering the lake floor with 700 mats, was implemented in 2011. It was a significant action against the invasive species that had been affecting the lake's ecosystem.

The Asian clam is an invasive species that can cause significant harm to the native ecosystem. It can outcompete native species for food and habitat, and can also alter the lake's water quality.

The 2011 treatment was a major success, with 97% of the clams in the treated area being eliminated. However, by 2019, the clams had made a comeback, with 27 sites identified in the lake.

As a result, efforts have shifted to monitoring the spread and impact of the invasive clams on the ecosystem. This includes tracking the clams' population and monitoring their effects on the lake's native species and water quality.

The use of benthic barrier treatments is a common method for controlling invasive species in lakes and other water bodies. The mats used in the treatment are designed to prevent the clams from moving and feeding, effectively suffocating them.

The success of the 2011 treatment in Lake George demonstrates the effectiveness of this method in controlling invasive species. However, the comeback of the clams in 2019 highlights the need for ongoing monitoring and management efforts to prevent the spread of invasive species.

Invasive species can have significant economic and environmental impacts, and their control is an important part of maintaining healthy ecosystems. The experience of Lake George in controlling its invasive Asian clam population can provide valuable lessons for other lakes and water bodies facing similar challenges.

The Lake George example also underscores the importance of continued vigilance and monitoring in the fight against invasive species. Even after successful treatment, it is crucial to continue monitoring the ecosystem to prevent the re-establishment of invasive species.

Overall, the use of benthic barrier treatments in Lake George has been a significant step in controlling the invasive Asian clam population, and its success can inform management efforts in other lakes and water bodies.

The story of Lake George's fight against invasive clams serves as a reminder of the importance of protecting our ecosystems from the harmful effects of invasive species. It highlights the need for ongoing management and monitoring efforts to prevent the spread of invasive species and maintain healthy ecosystems.

In conclusion, the Lake George example demonstrates the effectiveness of benthic barrier treatments in controlling invasive species, and the importance of continued monitoring and management efforts to prevent their spread.
