Overview of Mustard Marsh
This marsh is named because the aerial signature looks like dijon mustard and has a smooth to chunky look to it. It does not have the puffy or shiny look present in the other types. This form of Reed Tidal Marsh is found every once and awhile north of the Cedar Swamp watershed. It can be one of the easiest forms of Reed Tidal Marsh to find and one of the hardest depending on the background marsh or the site conditions. Often the marsh types can occur together (see below). Site conditions could potentially cause the appearance of this marsh.

Below is an image with mustard marsh in it. See if you can find it. An image with the delineated marsh is provided at the end of the post.

Aerial Image with two marshes together
Shown below is an aerial image from Blackbird Creek showing both mustard marsh and cotton marsh together. Either of the Reed Tidal Marsh type can occur adjacent to one another.

“Mustard marsh” is outlined in red and “cotton marsh” is outlined in blue.
