[email protected]. WET MEADOW PLANT ASSOCIATIONS, MALHEUR NATIONAL WILDLIFE REFUGE, HARNEY COUNTY, OREGON John A. Christy Oregon Biodiversity Information Center, Institute for Natural Resources Portland State University January 2013 1 Summary In July 2012, we sampled 131 plots in wet meadow habitat at the southern end of the Malheur National Wildlife Refuge. Analysis of the data identified eleven different plant associations: Alopecurus pratensis, Carex aquatilis var. aquatilis, Carex nebrascensis, Carex pellita, Carex praegracilis, Carex sheldonii, Distichlis spicata, Juncus balticus, Leymus triticoides, Phalaris arundinacea, and Sparganium eurycarpum. Plant associations spanned a wetland gradient from seasonally moist to seasonally or perennially flooded, but surface water had left most stands at time of sampling. Mean Wetland Indicator Status scores help to place the plant associations within gradients in soil moisture and alkalinity.
