Hurricanes' toll: 320 million trees

Date : 16th November 2007, Source : Seattle Times

WASHINGTON New satellite imaging has revealed that hurricanes Katrina and Rita produced the largest single forestry disaster on record in America an essentially unreported ecological catastrophe that killed or severely damaged about 320 million trees in Mississippi and Louisiana. The die-off, caused initially by wind and later by weeks-long pooling of stagnant water, was so massive that researchers say it will add significantly to the global greenhouse-gas buildup ultimately putting as much carbon from dying vegetation into the air as the rest of the nation's forests take out in a year of photosynthesis. In addition, the downing of so many trees has opened vast and sometimes fragile tracts to several aggressive and fast-growing exotic species that are already squeezing out far more environmentally productive native species.
