Field Notes
We were in the Scarboro Marsh to look for our study species, to make bacterial colonies called Winogradsky columns, and to observe human impact. We are doing this fieldwork as part of an expedition on the way saltmarshes work. It was raining when we got to the site - Eastern Trail. Textures I felt were: slimy shells, smooth grass, jagged rocks, turning gravel, wet mud, icky-gooey unstable ground. Sounds heard were: wind, cars, raindrops, laughter, branches/leaves rustling, willet calling. Smells were sulfur, fish, water, salt air. After lunch a glorious wind blew through! We collected a lot if information and now have a condo of marsh bacteria set up at school.

Supporting Evidence
Photo of my evidence.
leaf length = 27.5 cm leaf width = 1 cm The leaf size matches the stats on the id card.

The plant was found 5 meters from the waterline. This puts it in the low marsh where we expect to see cordgrass.
Photo of my evidence.
The Cord grass is dead and lying flat on the ground. It is brown and was probably swept in my the tide. Even dead it matches the length and width of the description on the ID card.

Comments

Looks like you got it.

Cordgrass often grows on those blocks of sediment. Even though there's not much there to look at, given time of year, habitat, etc. It's almost certain that's what you were looking at.
