Physical and Biological Monitoring Data Collected from Restored Wetland Units at Shiawassee National Wildlife Refuge, Saginaw, MI, USA (2021)

These data describe water chemistry and fish, macroinvertebrate and vegetation communities within recently restored, historically-restored, and unrestored wetland management units of the Shiawassee National Wildlife Refuge (SNWR; Michigan, USA). Data were collected in 2021 according to protocols and methods described in Conrad et al. 2022. These methods developed through previous years of fieldwork at SNWR and are similar to those implemented in the Great Lakes Coastal Wetlands Monitoring Program (CWMP) (Greenberg et al. 2021; Lugten et al. 2020; Uzarski et al. 2016). Water chemistry data include either field or lab-derived measurements including temperature, pH, turbidity, conductivity, dissolved oxygen, ammonia, chloride, sulfate, nitrite, nitrate, silicon dioxide, soluble reactive phosphorus, total phosphorus, total Kjeldahl nitrogen, suspended solids, and fluoride. Biological community data include taxa identifications and abundance estimates for macroinvertebrates, fish, and vegetation. Taxa are identified to the species level when practicable, with data derived from floral surveys, electrofishing, fyke net sets and macroinvertebrate dip net sampling. These data may serve as indicators of system quality or health, enabling users to conduct comparative analyses among different wetland areas and, in conjunction with cross referenced datasets, make comparisons across years.
