Academy authority on delta bulrush says 'his' plant could help ease oil spill crisis
Date:6/28/2010

PHILADELPHIA, PA (June 28, 2010)A revered botanist at the Academy of Natural Sciences who first profiled and then named the delta bulrush says the plant has natural properties that could help reduce the impact of the Gulf oil spill on the Mississippi delta.

Dr. Alfred Ernest Schuyler, the Academy's curator emeritus of botany and a prominent botanist in the international science community, is urging all sides involved in the crisis to give this slender sedge family member a hard look as they weigh their spill-fighting strategies.

Schuyler described and named Scirpus deltarum, now known as Schoenoplectus deltarum the delta bulrush, in 1970 after doing field research in the Mississippi delta. Based on the detoxification properties of similar bulrush species, Schuyler thinks the delta bulrush could be instrumental in decomposing the oil and reducing its impact on other threatened marsh plants.

He says a close relative of the delta bulrush, the common three-square (Schoenoplectus pungens), can transmit oxygen to underwater microorganisms capable of decomposing oil. "Presumably, the closely-related delta bulrush can do the same thing," Schuyler explains.

Schuyler says the fascinating marsh plant he named more than three decades ago now urgently deserves further study of its potential to decompose oil.

Abundant in the Mobile, Mississippi, and Atchafalaya deltas, plants such as the delta bulrush will be the first that the oil will encounter, and may act as a buffer for the rest of the wetlands, says Schuyler.

"Bulrushes are environmental workhorses, effectively used in sewage lagoons to purify water," Schuyler explains. "Air cavities in the stems transport oxygen to underwater portions of the plants, making the oxygen available to microbes capable of decomposing pollutants in the sewage." He theorizes that this same capacity to decompose pollutants in sewage most likely would come into pl
