WHITE PAPER: San Pablo Baylands: Ensuring a Resilient Shoreline

Spring 2017 newsletterOctober 26, 2017

This white paper was prepared by the SR 37 — Baylands Group, comprised of North Bay wetland management partners, including Sonoma Land Trust, in response to the State Route 37 redesign effort led by the Metropolitan Transportation Commission and the elected officials and transportation authorities of Marin, Sonoma, Napa and Solano Counties. This document summarizes existing ecological conditions of the San Pablo Baylands and the conservation investments made by Sonoma Land Trust and our partners, and provides recommendations to ensure that the highway redesign is consistent with our conservation and restoration goals.

Sonoma Baylands Oral History Project

2014-15 annual reportThe Sonoma Baylands are the lands around San Pablo Bay that were now or historically submerged by the tides. The story of the Baylands is one of change. Not only has the landscape undergone continual changes, but so have the people and our perspectives. This new report and video, a partnership between Sonoma Land Trust, the Sonoma RCD and local landowners, sheds light on the complexities of the areas’ cultural and land use history. Portraying a vast history of native use, economic incentive, agricultural productivity, and land preservation, the project tells the story of those who have stewarded this ever changing place, then and now.

Sonoma Valley Wildlife Corridor Road Underpass Use Report

In 2013, Sonoma Land Trust began a multi-year study, funded in part by the Gordon and Betty Moore Foundation, to determine whether wild animals are able to move freely through a designated wildlife corridor. As part of the larger study, we placed cameras at underpasses to determine if these structures are facilitating wildlife movement under Highway 12 and Arnold Drive within and adjacent to the corridor. Roads often fragment landscapes, but they may be permeable to safe wildlife passage where crossing structures are available. This report describes and summarizes data and findings from the first year of data collected at several underpasses.


Wildlife Corridor Mgmt & Monitoring Strategy

The Sonoma Valley Wildlife Corridor is a constricted, yet vital, connection through which wildlife may move through a fragmented landscape. It is also at serious risk of being lost. The Management and Monitoring Strategy describes current conditions limiting wildlife passage in the corridor and provides recommendations to mitigate for or remove barriers on corridor lands synthesized from current literature, biological surveys, property assessments and a panel of experts. It also articulates a monitoring plan to develop a picture of wildlife in the region and their movement across the landscape.

Jenner Headlands Integrated Resource Management Plan (IRMP)

March 2012

The Jenner Headlands IRMP is the guiding document for the protection, restoration and enhancement of the diverse natural ecosystems and cultural resources of the Headlands. The IRMP was developed by the Sonoma Land Trust in close partnership with The Wildlands Conservancy. Together, our organizations are dedicated to restoring the redwood forests, revitalizing the creeks, providing places for native plants and wildlife to prosper, and ensuring that the community and future generations can come to the Headlands for the breathtaking ocean views and simple joy found in nature.

Sears Point Wetlands and Watershed Restoration Project
Final Preliminary Plan

February 2007
Since 2004, SLT has conducted an extensive data collection effort and stakeholder driven wetlands and watershed restoration planning process, culminating in this Sears Point Wetlands and Watershed Restoration Project Final Preliminary Plan. This Plan’s Project Vision calls for tidal marsh restoration on 970 acres south of the rail line, retaining and modifying agricultural practices to enhance seasonal wetlands and grasslands on 400 acres north of the rail line, modifying grazing and implementing watershed management activities to benefit grasslands, seasonal wetlands and riparian corridors on almost 1,000 acres of uplands, and as much as 6 miles of new Bay Trail.

Sears Point Restoration Project Draft Preliminary
Restoration Plan

February 2006
This Plan presents an overview of the Sears Point Restoration Project and proposed alternatives for restoring, enhancing, and managing several ecosystem types on the 2327 acre property located in southern Sonoma County at the edge of San Francisco Bay. The restoration, enhancement and management options are based on the historic and present conditions of the land, the project’s environmental setting, feasibility of actions, and broadly supported goals and objectives. Extensive data collection and analysis provides the technical foundation for development of alternatives which include restoration of tidal and seasonal wetlands and upland grasslands, continuation of existing agricultural uses, and a segment of the San Francisco Bay Trail.

Laguna de Santa Rosa: Resource Atlas and Protection Plan

May 2003
The Laguna de Santa Rosa, the 14 mile waterway stretching from Cotati to the Russian River in central Sonoma County and the adjacent Santa Rosa Plain, together form one of the most ecologically and socially important systems in coastal Northern California. This report provides detailed maps about the natural and social resource of the Laguna, and an action plan that describes a strategy for protecting the Laguna’s critical habitat, floodplain, open space and recreational values. The Plan includes a strategy for preservation of key resource areas, development of recreational trails, and restoration and management of existing resource lands.

Russian River/North Coast Parcel Analysis

May 2002
This report builds on the Sonoma County Coastal Parcel Study by presenting a strategic approach to land and resource conservation for the Sonoma Coast from the Russian River north to the Mendocino County line. A series of maps describe land use, existing conservation lands, natural resource and recreational values in this area. This information is analyzed to develop a priority list of 12 properties whose acquisition will significantly advance landscape scale conservation in the region.

Sonoma County Coastal Parcel Study

November 1999
The Sonoma Coast between the Russian River and the Marin County border is an area of spectacular beauty, diversity and abundant natural resources. This report analyzes existing land use and presents an acquisition strategy that identifies properties that have exceptional resource values, are adjacent to existing conservation lands and provide the potential for public access. Primary and secondary acquisition targets are identified; since the publication of this report, all of the primary acquisition properties have been protected for conservation.

SLT has conducted extensive data collection efforts and stakeholder driven wetlands and watershed restoration planning processes. We make the findings available to the public in these reports.
