David A. Lawson, assistant director, Massachusetts Mosquito Control, takes water from the Broad Meadows Marsh Restoration project, Quincy, Mass., to check for mosquito larvae. The project is set to restore the area by creating 35 acres of high and low salt marsh (including channels), 20 acres of high marsh, and five acres of bordering vegetative wetlands, all aiming to increase the ecological value of the area. To do this, the area will have to be excavated to get rid of Phragmites australis, and to bring the floor back to pre-1950’s levels to provide the right conditions for the salt marsh to redevelop.
