Similar Ecological Communities

Clear dominance by cat-tail (Typha spp.) distinguishes this type from the other marsh/palustrine herbaceous types that occur in similar settings.

Cat-tail Marsh

Conservation Value

Cat-tail Marsh can serve as an important habitat and food source for muskrats and shorebirds, such as the Marsh Wren (Cistothorus palustris) and American Bittern (Botaurus lentiginosus). This community also serves as a buffer for sediment and pollution runoff from adjacent developed lands by slowing the flow of surficial water causing sediment to settle within this wetland.

Threats

Alteration to the hydrological regime and development are the major threats to this community (e.g., impoundments, beaver dams) and can lead to habitat destruction and/or shifts in community function and dynamics. Clearing and development of adjacent land can lead to an accumulation of agricultural run-off and pollution as well as sedimentation. Invasive plant species such as purple loosestrife (Lythrum salicaria) and common reed (Phragmites australis) can occur in this community. Cat-tail Marsh communities themselves can be a threat to other wetland communities through the clonal growth of cat-tails and displacement of other vegetation types.

Management

A natural buffer around the wetland should be maintained in order to minimize nutrient runoff, pollution, and sedimentation. The potential for soil erosion based on soil texture, condition of the adjacent vegetation (mature forests vs. clearcuts) and the topography of the surrounding area (i.e., degree of slope) should be considered when establishing buffers. The buffer size should be increased if soils are erodible, adjacent vegetation has been logged, and the topography is steep as such factors could contribute to increased sedimentation and nutrient pollution. Direct impacts and habitat alteration should be avoided (e.g., roads, trails, filling of wetlands) and low impact alternatives (e.g., elevated footpaths, boardwalks, bridges) should be utilized in situations where accessing the wetland can not be avoided. Care should also be taken to control and prevent the spread of invasive species within the wetland.
