The rationale for attempting to define salt marsh mosquito-breeding areas in Galveston County by remote sensing the associated vegetation.

This presentation is concerned with the rationale for attempting to define salt marsh mosquito breeding areas in Galveston County. It includes a botanical survey of the marsh plant communities, their relationship to flooding, and their exposure to salt water. Particular emphasis is given to Distichlis spicata, a widespread marsh grass. Evidence suggests that breeding areas of Aedes sollicitans are associated with Distichlis and that both species respond to similar ecological conditions in the salt marsh. Aspects of the remote sensing of the Distichlis are considered.
