Carex of Goethe State Forest, Florida By Linda W. Curtis [email protected] Carex are grasslike in leafy appearance but have seed heads with entirely different structures. Above, a cluster of five Carex species grew in the herb ground layer near Ten Mile Creek in Goethe State Forest. A few culms with seed heads were taken, scanned, and sent to University of Florida herbaria with labels recording global positions. Carex species grow in specific habitats with moisture and sunlight requirements. The logging of trees opened the ground layer to more sunlight, at least part of the day. Mature forests with massive thatch buildup diminish the ground layer herbs while prescribed fires open the soil and allow its hidden seed bank to germinate and flourish again. Carex are an important part of the terrestrial food chain.

Carex  of  Goethe  State  Forest,  Florida                                                                            By  Linda  W.  Curtis  [email protected]  

   

Carex  are  grass-­‐like  in  leafy  appearance  but  have  seed  heads  with  entirely  different  structures.  Above,  a  cluster  of  five  Carex  species  grew  in  the  herb  ground  layer  near  Ten  Mile  Creek  in  Goethe  State  Forest.  A  few  culms  with  seed  heads  were  taken,  scanned,  and  sent  to  University  of  Florida  herbaria  with  labels  recording  global  positions.    Carex  species  grow  in  specific  habitats  with  moisture  and  sunlight  requirements.  The  logging  of  trees  opened  the  ground  layer  to  more  sunlight,  at  least  part  of  the  day.  Mature  forests  with  massive  thatch  build-­‐up  diminish  the  ground  layer  herbs  while  prescribed  fires  open  the  soil  and  allow  its  hidden  seed  bank  to  germinate  and  flourish  again.  Carex  are  an  important  part  of  the  terrestrial  food  chain.

Carex  of  Goethe  State  Forest,  Florida  By  Linda  W.  Curtis  [email protected] 4-12-2013  Contact:  Bobby  Cahal,  Forestry  Supervisor  II,  Goeth  State  Forest,  9110  SE  County  Road  337,  Dunnellon  Fl.  34431  [email protected]    ABSTRACT    Goethe  State  Forest  is  in  the  southeastern  portion  of  Levy  County  in  Morriston,  north  of  Dunnellon  and  includes  the  Rainbow  River.  With  more  than  15  habitats,  Carex  species  grow  in  all  except  deepwater  aquatic.    Of  the  approximate  35  Carex  species  known  in  the  Central  Gulf  Coast,  five  were  found  at  Goethe  State  Forest:    C.  fissa  var.  aristata  Mack.,  C.  gholsonii  Naczi  and  Cochrane,  C.  godfreyi    Naczi,    C.  longii  Mack.,  and  C.  lupuliformis    Sartwell  ex  Dewey.  Comparisons  were  made  to  the  Carex  species  that  grow  in  Devil’s  Hammock  Wildlife  Management  Area  and  the  Waccasassa  Bay  State  Preserve,  both  in  Levy  County.    INTRODUCTION    Goethe  State  Forest  is  a  large  tract  in  Levy  County  with  a  smaller  Watermelon  Pond  Unit  separate  from  the  main  tract  in  both  Levy  and  Alachua  County.  The  grass-­‐like  Carex  grow  in  the  herb  layer  of  at  least  ten  habitats  including  scrubby  flatwoods,  dome  (cypress)  swamps,  swamp  basins  and  sandhills.  Of  the  three  trailheads,  two  enter  from  Hi  337,  Black  Prong  and  Apex,  while  Tidewater  Trailhead  is  accessed  from  Hi  336.  (Fig.  1).      METHODS    The  Permit  to  Collect  at  Goethe  State  Forest  was  granted  for  4-­‐11-­‐2011  to  4-­‐30-­‐2012,  Permit  #  11-­‐68  by  Sherry  Bennett  Forest  Officer  [email protected].    Map  work  included  viewing  topographic  and  satellite  photos.  Fieldwork  required  checking  clumps  and  tufts  for  triangular  or  trigonous  culms,  then  for  sac-­‐like  perigynia  around  each  seed-­‐like  achene.  Mature  culms  with  seed  heads  and  leaves  were  imaged  with  a  camera  that  records  GPS  data  in  the  field.  The  fresh  culms  were  scanned  onto  computer  first  and  then  their  perigynia  were  micro-­‐imaged  with  a  digital  camera  mounted  on  a  bioscope.      After  pressing  and  drying,  the  plants  were  identified  using  Guide  to  the  Vascular  Plants  of  Florida  (2011)  and  Flora  of  North  America  Vol.  23:  Cyperaceae,  (2002)  and  by  viewing  online  herbaria  images  from  herbaria  websites.  Specimens  were  labeled  and  sent  to  Florida  herbaria at University of South Florida -Tampa, University of Florida-Gainesville, and Florida State University-Tallahassee. One specimen was not keyable and is C. sp. (i.e. unknown).

 RESULTS    Five  species  were  found  and  2  were  recently  discovered  in  Florida  and  named    C.  godfreyi  (Naczi,  Bryson  &  Cochrane,  1993)  and  C.  gholsonii  (Naczi  2002).  The  largest  Carex  was  C.  lupuliformis.    C.  fissa  and  C.  longii  were  common  in  clearings  .    Table 1.

 Two  other  inventories  were  compared:  Waccassassa  Bay  State  Preserve  (with  eight  Carex  species  (Abbott  and  Judd,  2002)  (Table  2)  and  Devils  Hammock  Wildlife  Management  Area  with  18  species  (Abbot,  2008)  (Table  3).  Florida has 71 Carex listed in Guide to the Vascular plants of Florida (Wunderlin and Hansen, 2011). Half of the 71 Carex only grow in the northern tier of counties in the Panhandle but Central Florida has approximately 35 different species. TABLE 2. Carex of Waccasassa Bay State Preserve, Levy Co.

Warty Sedge Bogs, swamps, ponds  CONCLUSION Goethe  State  Forest  is  one  of  the  largest  tracts  of  contiguous,  old  growth  longleaf  pine  flatwoods  in  Florida.  Some  of  the  habitats  are  fire  dependent  and  upland  Carex  flourish  after  fires  but  diminish  after  years  of  leaf  litter.  Wetland  Carex  also  increased  by  rhizomes  and  seedlings  deeper  into  the  drying  cypress  swamps.  A  diverse  patch  of  five  Carex  species  grew  in  the  unnamed  trail  entry  along  Hi  336  near  Ten  Mile  Creek  and  included  C.  lupuliformi,s  C.  gholsonii,  C.  godfreyi,  C.  fissa,    and  C.  longii..  Continued searches would result in more species discovered with a potential for 18 species as known at Devil’s Hammock, also in Levy County.
