Rank and status: To learn more about species rank and status, see the working list key. WWAP (Wisconsin Wildlife Action Plan): SGCN (Species of Greatest Conservation Need) = These species have low and/or declining populations that are in need of conservation action. SIN (Species with Information Needs) = These species have experienced, or are believed to have experienced, a statewide or range-wide decline, but are in need of inventory and monitoring efforts to determine their if they are SGCN or not. Mapped in NHI (Natural Heritage Inventory): Y = Observations of these species are mapped into the NHI database and are used for a variety of purposes including research, land management, state land master planning, community planning, conservation planning and review of public and private activities across the state. N = Observations of these species are not currently mapped in the NHI database.
