The marsh supports typical marsh birds including breeding Wilson's Snipe, American Bittern, Northern Harrier, both Alder and Willow flycatchers, Nashville Warbler, Northern Waterthrush, Yellow Warbler, Common Yellowthroat and Swamp Sparrow. Sandhill Crane breeds in the general vicinity and can be heard calling and has been observed in flight over the marsh. In May 2022 a Blue-winged Warbler was heard and observed singing from the willow-alder thickets on the south side of the road at the southeast corner of the marsh.

This large cattail marsh is located on the north side of Otonabee-South Monaghan 3rd Line just a few hundred metres west of Nicholson Rd. The cattail marsh is bounded to the east and west by willow-alder-dogwood thicket swamp and to the north by mixed swamp. This wetland is part of the headwaters for Steamboat Creek, which runs south under the Third Line. All land on either side of the road is in private ownership, so do not leave the road.
