| A basic restoration question is what plants should be restored when site conditions are not fully restorable? I have tackled this issue for wetlands with altered hydrological conditions. My field studies of Dane County sedge meadows show that the combination of hydrological disturbances and invasion by Phalaris arundinacea (reed canary grass) most accelerates the loss of native plant species and lowers floristic quality. Mesocosm experiments verified the role of interactions among flooding and nutrient addition, as well as other disturbances. The mesocosm results support and augment current theory of fluctuating resource supplies. My microcosm experiments demonstrated differential tolerance and responses to hydroperiods. My evaluation of alternative field methods (quality-control measures) contributes to the current debate on how best to assess vegetation. |
