Our Habitat Improvement Group has been taking over oak tree planting in our Open Space. Seedling preservation is a much less labor-intensive method of getting the next generation of oak trees going on open land. Grazing in our public open space has changed, resulting in the loss of many young oaks and other trees we've planted due to the explosion of vole populations. Taller, un-grazed grass favors voles and gophers, so we plan to deal with the 'new rodent problem' by protecting existing trees and seedlings. We have been doing this since 1995 and have learned, by trial and error, what works and what does not work, and we share that with other Open Space groups around the Bay Area so they can improve habitat in their own public open spaces. When oaks are restored, can eagles and burrowing owls be far behind?
