The timber interests were against the move and I thought the bush administration might try to undo it on economic grounds , but only 5 percent of the nations timber came from national forests , and only 5 percent of that amount came from roadless areas .
It was the biggest conservation step I had taken since preserving 43 million roadless acres in our national forests , and a needed one , since ocean pollution was threatening reefs the world over , including the great barrier reef in australia .
