We describe the locations and habitat characteristics of 10 of the 14 known populations of Aster furcatus in Wisconsin. We were unable to identify any particularly unusual features of A. furcatus habitats which could be related to its rarity. The rarity of forked aster is probably not related to specialized habitats, but is most likely the result of requirements for moderate disturbance, inability to withstand competition, poor reproduction from seed, and low genetic variance.

Temperature, pH, alkalinity, total-N, total-P, K, Na, Ca and Mg levels were measured in groundwater at the Pickerel Lake and Ottawa Lake calcareous fens and the Cedarburg Bog patterned fen. The two calcareous fens were similar in all chemical characteristics. Alkalinity, pH and Mg were significantly lower in the patterned fen when compared to the calcareous fens, while the other chemical parameters were similar. Each of these southeastern Wisconsin fens supported Sarracenia purpurea (pitcher plant). When the characteristics of the groundwater of the areas that supported S. purpurea were compared with those of areas that did not support S. purpurea, …
