Dear Fight For the Reef Campaign,

I am writing this letter to agree with your point on how dredging should be banned as it effects the flora and fauna, disturbs the water flow and damages the environment.

Dredging is scraping the bottom of a river, seafloor or other marine habitat to remove silt, open up a channel, make the river floor deeper to accommodate larger boats and prevent flooding or better drain nearby land. Occasionally law enforcement officials dredge to find evidence in a crime, but in those cases, silt is usually disturbed but not removed.

Finally, dredging seriously damages the environment. Sediments are thrown into the

Atlantic Sturgeon Research Paper

spawning ground and change the dynamics and flow of the rivers (ASSRT 1998). This decreases the spawning rates of the Sturgeon which stops the growth of the species.
