'Delta bulrush' plant could help ease oil spill crisis: Botanist | The delta bulrush plant has natural properties that could reduce the impact of the Gulf spill, according to an eminent botanist. Dr. Alfred Ernest
Schuyler, the Academy's curator emeritus of botany, said that the plant Scirpus
deltarum or delta bulrush has detoxification properties that could decompose the
oil and protect the marsh plants. According to Schuyler, the common three-square
(Schoenoplectus pungens), can transmit oxygen to underwater microorganisms capable
of decomposing oil. "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," Schuyler said. The botanist added that these plants
are more tolerant of oil than any other but it is too soon to estimate how much
oil is too much for the delta bulrushes. If the oil were to cover the plants,
Schuyler recommends harvesting them just below the oil line. |
