The daily planners and electronic organizers of some students, faculty and staff members, and alumni at the University of California, Davis, have intriguing entries this week -- from planting trees or building a house to collecting donations of diapers and sorting used clothing.

About 400 members of the campus community, mostly students, will give a leg up to about 25 community service and civic organizations in Davis, Yolo County and Sacramento during the campus' second annual Week of Service running through Sunday, Feb. 17.

The annual event has been organized by Human Corps, a student-managed office dedicated to matching campus volunteers with organizations seeking help.

"The week fosters the value of community service, highlights opportunities in the local area and helps people enjoy the reward of serving others," says Kim Bahrami, student manager of Human Corps.

Organizations participating in service week range from the Yolo County Hospice Thrift Shop and the Sacramento Crisis Nursery to Habitat for Humanity and a city of Davis parks program. Volunteers will build children's furniture or visit seniors in their homes to help them learn to use computers. Some will paint office interiors; others will paint murals. Yet others will serve meals to the homeless.

Last year, Human Corps facilitated about 240,000 hours of community service by matching 1,300 campus volunteers with 100 organizations.
