marsh mog
n.— «For the past two years officials have used a modified snow-grooming machine to spray the herbicide. The widely spaced tracks of the marsh mog, as it is called, allow the machine to tread lightly on the fragile tidal ecosystem. This year, officials are doing all the work by hand because large swaths of Spartina have already been wiped out. Only small isolated stands remain.» —“Invasive Spartina eradication to be discussed tonight” by Marc Albert Alameda Sun (California) June 29, 2007. (source: Double-Tongued Dictionary)
