Welcome to Bog Brook!


Bog Brook cattail marsh, 3/31/12

    The wetland surrounding most portions of Bog Brook in Monmouth, ME consists of over 1,500 acres of different wetland types. This study focused on the deciduous forested/shrub and cattail marsh portions of the wetland that are located at the intersection of Bog Road and Route 202 in Monmouth. It can be accessed via Route 202 approximately 200ft from the intersection. Here there is a snowmobile/ATV trail that allows access to the forested section of the wetland. The emergent section of the wetland can be accessed anywhere from Bog Brook Rd with chest waders.  According to the Monmouth Property Tax Map 25, Lot #4, which encompasses my area of interest, matches the records for the Monmouth Fish and Game Association.


In 1946, the Monmouth Fish and Game Associate was founded in the section of Bog Brook wetland that is approximately one quarter mile from the intersection of the Bog Road and US Route 202. Aside from this establishment, there are no dwellings within the immediate vicinity of this section of wetland.  Beyond this there are only a handful of sparsely spaced houses and businesses. Though there has not been any documented research or important history of the site, this type of wetland is referenced in research articles which study the use of cattail species in constructed wetland systems to remove heavy metals from wastewater (Maine et al., 2005; Marchand et al., 2010).


Wetland Characteristics



Bog Brook Wetland is fed by Bonney Pond to the south and Bog Brook to the east, which runs south to north into Androscoggin Lake to the north. No water classifications have been found for Bog Brook, however Androscoggin Lake is a category 2 meaning it attains some designated uses (Maine Department of Environmental Protection, 2010). Flooding and ponding are likely in the cattail marsh section of the wetland only.

The two soil types found in the cattail marsh are togus fiberous peat and scarboro mucky peat (USDA, 2012).  Both of these soils are high in organic matter and stay saturated for most of the year.  Both of these soils are also formed on sandy glacial outwash material. Soils found in the deciduous forested/shrub wetland are Scantic and Scio (USDA, 2012).  These soils are mineral soils that are gray or red in color.  Though the depth to water table could be as little as 12 inches, for most of the year the soils are not saturated to the surface.

All plant photos and samples were taken during a March 31, 2012 site visit. At this time, most vegetation had not yet begun to sprout with only a few live plants having emerged. This situation was as expected in early spring. Plant identification was performed using remains from last year’s stand. No other organisms, including humans, were observed using this section of the wetland at this time.  However, approximately a quarter mile to the south was a firing range being actively used. Though not directly being utilized by humans, this particular section of wetland was hugely impacted by the intersecting road as evidenced by the trash littered along the entire stretch of emergent wetland.

The forested section of the wetland did not appear to be flooded in any location. However, the emergent marsh had standing water throughout. Common Cattails dominated almost entirely in the inner flooded portions of the marsh but other shrub species such as Sensitive Fern, Winterberry, and Sweetgale existed around the unsaturated edges.

In the forested section of wetland, Red Maple, Gray Birch, and Sensitive Fern were dominant. Other species present included White Pine, Speckled Alder, Common Winterberry, Northern Red Oak and Cinnamon Fern.
