Piedmont area of South Carolina. Xeric pine forest. This grass is a
real nuisance. Needle grass? Wire grass? Neither seem exactly right but I'm new to this. What have I forgotten to include? See photos at: http://www.flickr.com/photos/raphanus97/ Thanks! |

See photos at: http://www.flickr.com/photos/raphanus97/ Thanks! *** My hat off to anybody who can identify this from these pictures! Pictures of grass should preferably include the inflorescence / infructescence. Sometimes a grass in the vegetative state can be identified (not easy); and a good spot to include in a photograph is where the sheath of the leaf opens and the blade angles away. Quite often, to know what details are important to focus on, one has to some idea what general group the grass belongs to. PvR |

oups.com... Piedmont area of South Carolina. Xeric pine forest. This grass is a real nuisance. Needle grass? Wire grass? Neither seem exactly right but I'm new to this. What have I forgotten to include? See photos at: http://www.flickr.com/photos/raphanus97/ Well, it sounds like you've seen a good example of a now rather endangered natural habitat type. Is it something like http://www.srs.fs.usda.gov/gallery/d...e_grass049.jpg ? http://www.fs.fed.us/wildflowers/reg...regrass_lg.jpg Wiregrass isn't so much a "nuisance" as a characteristic and important part of the longleaf pine/wiregrass savanna plant community of the Southeast US, which is now largely lost or destroyed [it's adapted to/dependent on frequent fires]: http://www.fws.gov/carolinasandhills/longleaf.html http://www.fws.gov/southeast/partners/pfwpine.html http://www.learnnc.org/lp/editions/cede_longleaf/2 http://www.auburn.edu/academic/fores...gleafalliance/ From http://www.jonesctr.org/research/llp...storation.html : "Three-awn wiregrass (Aristida beyrichiana) is considered to be a keystone species in the longleaf pine-wiregrass ecosystem because of its flammability, its role in facilitating fuel accumulation, its cover for bird nesting, and its structural dominance of the ground cover. The presence of wiregrass is often used to indicate relatively undisturbed longleaf pine communities because wiregrass is not known to re-establish dominance on previously cultivated sites and is less vigorous without periodic fire disturbance. The pines may in fact need the grass: http://forestry.about.com/b/a/006455.htm Even if not, other organisms might: http://www.lakejacksonturtles.org/aresco/tortoise.html cheers |
