THREATS: • As the quality of the groundwater that supplies a large portion of the water of the Mink River is critical to the health of this wetland dominated system, any contamination of this groundwater would degrade the quality of this site. Possible sources of contamination to this groundwater could include leaking or failing septic systems in the watershed, or increased nutrient loading of the groundwater from poor fertilizer management in the watershed. • Surface water runoff also may contribute degrading influences to the system. Sources of contaminants would likely be runoff from paved or impervious surfaces within the watershed. This could be of particular concern where Highway 42 crosses the Mink River and further upstream. • Another threat to the health of the Mink River landscape is the presence of a number of non-native species of plants and animals. Carp in particular have invaded the shallow waters of the river negatively affecting the water quality. Zebra mussels have also been found in nearby Rowley’s Bay, although in low numbers. • Invasive plant species also pose a threat to this site. Purple loosestrife has been seen occasionally in the marsh, but has been controlled by pulling. Garlic mustard has recently been found along the shore of Rowley’s Bay. Other species such as Vinca, bitter sweet nightshade, autumn olive, Japanese knotweed and others are present in the landscape and if not controlled could prove damaging to the integrity of the natural communities of the site. • Dispersed home development in the woods of the Mink River landscape also pose a threat to the integrity of the site. Impacts such as direct habitat loss, forest fragmentation, groundwater contamination, and exotic species introduction often follow home development in intact forest settings. INFORMATION NEEDS / GAPS: • Groundwater recharge areas for the springs of the Mink River. • Location and abundance information on exotic species in the landscape.
