Four more tree sitters were arrested Tuesday, hours after climbers hired by Pacific Lumber Co. removed other activists from their perches more than 100 feet above the ground.
A protester arrested Monday, who gave her name only as "Remedy," was identified by authorities Tuesday as Jeny Crad, 28, of Olympia, Wash.
Pacific Lumber was focusing on removing 16 others named in a court order from majestic redwood trees in a grove near Eureka.
Company officials said it would take several days to remove all the tree sitters.
"This is an unpleasant situation forced upon us by people carrying out illegal, dangerous activities," Robert Manne, Pacific Lumber's president and chief executive, said in a statement Tuesday.
