Martinez 'local hero'

Bay Nature Institute's annual "Local Hero" awards dinner in March honored Cheyanna Washburn, a sophomore at Diablo Valley College, for youth engagement, making an outstanding contribution to the understanding, protection, and stewardship of the natural world of the San Francisco Bay Area.

Cheyanna previously participated in dozens of creek restoration and cleanup projects and played a leading role in designing and painting seven large murals on the life of John Muir as student at New Leaf Leadership Academy at Vicente Martinez High School in Martinez.

Cheyanna also taught elementary schoolchildren about watershed health and recycling, and encouraged a general interest in science.

She was an intern with the California Phenology Project, monitoring plants at the John Muir National Historic Site in Martinez for signs of climate change. She continues as the Youth Programs assistant at the historic site.

Last summer she was selected for a Yosemite Leadership Program summer internship, another step toward her dream of becoming a superintendent in the National Park Service.

Bay Nature also honored Craig Anderson, for conservation action, and Liam O'Brien for environmental education at the event. To learn more, visit www.Baynature.org.

Support for Shelter

Tim O'Keefe, director of Shelter Inc. of Contra Costa County, recently received a check for $1,500 from Martinez Rotary to help support services for more than 5,000 homeless people in Contra Costa County.

A third of the homeless in Contra Costa County are children who have a hard time going to school. Getting a roof over the heads of these children is the best way to get them back into school. A shelter stay can help people save enough money to make a rent deposit and make a new start.

Through the efforts of Shelter Inc., some 600 people will have beds tonight who would otherwise be on the streets. During its 27-year history, Shelter Inc. has helped nearly 200,000 people.

Martinez Rotary is proud to provide support in both dollars and in volunteer time to this essential program.
