  • Osborn, Joshua M.; Hagy, Heath M. (Illinois Natural History Survey, 2014-08-22)
    Rapid assessment of food production and subsequent availability is fundamental to evaluating habitat quality for waterfowl and management practices. Traditional methods of estimating food abundances (i.e., plot and core ...
