SALEM, Ore. -- A University of Oregon student who climbed 50 feet up a pine tree at the state Capitol has been cited on a trespassing charge, state officials said Friday.

Jasmine Zimmer-Stucky stayed in the tree overnight at the State Capitol State Park to protest a Bush administration plan that increases logging on land owned by the Bureau of Land Management.

Zimmer-Stucky is a member of the Eugene chapter of the environmental group Rising Tide, based in Britain. The group draws attention to climate-change issues, including public transportation and cap-and-trade permits.

Jim Bader, the State Capitol State Park manager, said the Parks and Recreation Department supports people using the park to express their views. However, he said camping is not allowed and people must obtain permits before staying overnight.

He also said the department doesn't allow platforms in park trees.

"Park rules are there to protect people and the park's resources," Bader said.

Zimmer-Stucky came down from the tree Friday after sitting in it for four days.
