A wildfire on the campus of UC Santa Cruz has damaged a grove of redwood trees.
It took firefighters six hours to put out the fire at an open area near Heller Drive and Meyer Drive.
It was reported at about 3 a.m. this morning.
The fire burned about an acre of cut grass before spreading into a grove of redwood trees, some of them about 90-feet tall.
There was no damage to any buildings, and no one was hurt.
Investigators said they think a campfire on the ground or in a hollowed-out tree stump may be to blame.
