Five Species of Sedge in a Small Wetland in Oxford

Donald A. Windsor

In a small wetland, less than half an acre, I found 5 species of sedge and 1 species of rush on 14 September 2010.

      No common name  Carex crinita   B 62 | G 339-40 | K 67, 69 #49
      No common name  Carex lupulina   B 58 | G 377  K | 64 #6 
      No common name  Carex intumescens   B 59 | G 376 | K 64 #4
      Threeway Sedge  Dulichium arundinaceum   B 101 | G 248 | K 54
      Woolgrass Sedge  Scirpus cyperinus   B 36-7 | G 275 | K 59

      Soft Rush  Juncus effusus   B 122 | G 406-7 | K 77, 79

The property is privately owned and is not open to the public, so I am not disclosing the owner's name.  It is located in the Town of Oxford, south of the Village, between County Road 32 (East River Road) and the Chenango River, in a kettle-kame terrain.  It sits at an elevation of around 1050 feet.  The river is about 0.1 mile west at an elevation of 970 feet.  East River Road is about 0.25 mile east at an elevation of 1090 feet.
Normally, this wetland contains standing water a foot or so deep atop mud.  This year, in September, it was dry enough to walk through without boots. 

If there are 5 species of sedges in one little wetland, how many are there in all of Chenango County?  I intend to find out.

Following the names of the sedges listed above are the references I used in identifying them.  The capital letters are initials of the authors listed below.  The numbers are the pages.  Numbers after a # are drawings.
