A study finding that logging on private timberlands is making streams warmer, potentially harming salmon, has prompted the Oregon Board of Forestry to consider tightening state logging standards.
Board of Forestry chairman John Blackwell said Monday that he expects the changes would amount to a "tweaking" of the Oregon Forest Practices Act, which sets standards for timber harvest on state and private lands.
The study by the Oregon Department of Forestry and Oregon State University found small to medium streams on private timberlands in the Coast Range saw an average increase of more than 1 degree Fahrenheit.
There was no increase on state timberlands, where more trees are left standing along streams.
Mill owner and board member Jennifer Phillippi says she expects only a small reduction in timber harvest.
