Logging trucks circled Sacramento streets yesterday to protest new, stricter timber rules proposed by California Gov. Gray Davis’s (D) administration, while Earth First! activists were arrested for protesting that the rules weren’t strict enough. The state Board of Forestry is scheduled to vote today on the rules, which would affect more than 16 million acres of privately owned forestland in the state, with the aim of reducing logging along rivers and streams to protect salmon populations. Loggers say the rules could put 30 percent of private timberland off-limits to cutting. Davis’s office appears to have been working on a compromise yesterday.
