Montini Open Space Preserve Draft Management Plan and Initial Study

Vision Statement “The Preserve will be an oak woodland and grassland that supports high quality habitat for a diversity of native Sonoma County wildlife and plants. The Preserve will support opportunities for research and will be a showcase for appropriate management of oaks and grasslands for the .

The gentle trails, rolling grasslands and oak woodlands, spring wildflowers, and spectacular views of the Sonoma Valley and San Pablo Bay will attract visitors who enjoy and appreciate the natural setting of Sonoma County. The public will have clear and easy access to the Preserve with minimal impacts to wildlife habitat. The Preserve will provide opportunities for persons with physical disabilities to enjoy the Preserve.

Partners will collaborate to provide a wide range of management, interpretive and environmental education programs. The Preserve will provide trail linkages, connecting the adjacent overlook trail with the regional bike trail and the Vallejo Home State Historic Park. The local community and visitors will enthusiastically identify and promote the Preserve as a regional and statewide tourist destination that contributes to economic development and enhances the quality of life in Sonoma.”

Public Use Currently, there is no formal recreational use occurring on the Preserve. However, there is a State Historic Park south of the Preserve and the Sonoma Overlook Trail across from Norrbom road to the east.

Some informal use has occurred historically on the Preserve, mostly partying and hiking.

Other Uses Homeless encampments have been observed on the Preserve.

Visual Resources The Montini Preserve meets several goals of the 1989 Sonoma County General Plan.

Goal 5. Cultural resources on the site will be protected and interpreted to promote the appreciation and stewardship of Sonoma’s historic importance.

Objective 1. Develop a minimum of one interpretive exhibit or program to educate the public regarding the cultural resources of the Preserve by 2010.

Narrative: Developing interpretive and educational materials to increase public understanding about local and State history is valuable given the importance of the Sonoma area and General Vallejo in California history.

Strategies: ƒ Develop exhibits to illustrate the role of the Preserve rock quarries in California history and the use of the quarried rocks in Sonoma and San Francisco streets. ƒ Develop exhibits to illustrate the role that General Vallejo played in California history. ƒ Solicit input and advice from local historians and others familiar with the history of the Preserve in planning, information gathering, and review of educational, interpretive, and outreach programs and publications. ƒ Include a cultural resource element when holding Preserve special events.

Habitat management activities would be monitored to assess whether the desired effect on habitat components has been achieved. At a minimum, susceptible oak trees would be monitored for SOD and changes in the weed population would be monitored. Baseline surveys would be established for plants and animals for which existing or historical numbers are currently not well known. It would also be important to monitor the effects of public use and disturbance on the resources of the Preserve.

Plan Amendment and Revision This plan has a ten-year life. At the end of ten, years, the plan should be evaluated to determine if plan objectives were met. If objectives were not met, the District would evaluate why they were not met. A new plan would address any unmet objectives and formulate new objectives for the management of this important open space preserve.

In addition, the plan will be evaluated annually to evaluate if objectives are being met and if strategies or objectives need to be modified. It may also be reviewed during routine inspections. Results of any of these reviews may indicate a need to modify the plan. The goals in the management plan will not change until they are reevaluated as
