Ferns of the Atchafalaya Basin.

The Atchafalaya Basin, located within the delta of the Atchafalaya River in south central Louisiana, contains the nation’s largest complex of bayous, forested wetlands, bottomland hardwood forests and swamps.  Biodiversity of plants and animals in this region is extraordinary, with both native and non-native species struggling to survive. We will head southwest of New Orleans towards Franklin, LA.  Our first stop will be along LA Hwy 390 where bayous meander through the forested wetlands.  Here we will see the floating antler fern, Ceratopteris pteridodies, along with other aquatic ferns such as Azolla caroliniana Salvinia minima and perhaps Salvinia molesta. Several Thelypteris species will also be encountered.  From here we will continue on towards Franklin, where we will visit the Bayou Teche National Wildlife Refuge, where one of their main goals is habitat management for the Federally-endangered Louisiana Black Bear.  The refuge contains a series of man-made levees that were constructed back in the early 1900’s to harvest Bald Cypress.  These elevated land masses traverse cypress swamps and harbor an interesting flora, including several rare ferns and fern allies such as: Dryopteris ludoviciana, Psilotum nudum, and Thelypteris interrupta (the only known location outside of south Florida).  In addition, we will see Asplenium platyneuron, Osmunda regalis, Thelypteris kunthii, and Woodwardia virginica to name a few. Depending on recent weather conditions, we may be able to drive to these locations, or if it has been very wet, we many have to walk from the nearest parking areas. Participates should expect hot-humid weather and should plan for sun or rain.  Bring sunscreen, hat, raincoat, insect repellant, boots or shoes that you do not mind getting wet or muddy.  It is also advised that you do not wear shorts or sandals.  Water will be provided. Lunch will be at Forest Restaurant in Franklin, where you can sample “real” cajun food.  Prices range from $8.00-$20.00, depending on if you want a sandwich or meal.  Distance to Franklin is approximately 100 miles, travel by van about 2.5 hours.
