Coordination of a Regional Biodiversity Conservation Strategy

Our goal is to facilitate the conservation of 50% of the Bay Area’s lands by 2050 by collaboratively setting regional goals that support local conservation and help achieve state-level strategies.

Conservation Lands Network

The Conservation Lands Network (CLN) is a regional strategy that sets goals, tracks progress, provides tools, and catalyzes on-the-ground land conservation in the San Francisco Bay Area. The CLN articulates two types of science-based and community-driven goals: a set of five overarching regional conservation goals and a much larger set of habitat-specific goals. 

Regional Conservation Goals

Through a peer-reviewed, science-based process, over 100 scientists, researchers, and land conservation practitioners identified regional goals for the conservation of biodiversity habitats.

The Conservation Lands Network 2.0 project, which was released in 2019, identified five regional goals: 

Conserve 2.5 million acres of priority lands by the year 2050. 2.5 million acres is approximately 50% of Bay Area land
Conserve rare, diverse, and irreplaceable landscapes, and manage them for health and resilience.
Conserve core habitats and the lands that connect them, and manage them for permeability, health, and resilience.
Conserve a regional network of streams, wetlands, ponds, seeps, and associated riparian and upland areas, and manage for health and resilience.
Steward all lands to maintain ecological and hydrological processes that support ecosystem function and resilience.

The CLN project includes tools to catalyze on-the-ground conservation. These tools aim to focus conservation in areas that represent the region’s biodiversity and support ecological function across the nearly 5 million acres that comprise the 10 Bay Area counties. Explore the tools >

CLN 3.0 Project

In 2025, with support from the State Coastal Conservancy, TOGETHER Bay Area is launching a mulit-year effort to update and expand the Conservation Lands Network with version 3.0. Our goals include: 

  • Through an inclusive process with the CLN community, produce CLN tools and deliverables including maps, data, online Explorer tool, and a written report.
  • Engage experts to determine if/how there meaningful and useful ways to incorporate wildfire, urban areas, stewardship, and agricultural lands into the CLN’s tools and deliverables that help advance 50×50. 
  • Identify ways to integrate the CLN with other TOGETHER programs including advocacy for regional funding and building alliances with Native American Tribes and communities. 
CLN 3.0 Steering Committee

The Steering Committee provides oversight on all aspects of the project, including ensuring the scientific integrity of the project, providing guidance on what new data should be included and interpreted, involving key stakeholders, and developing final recommendations.

CLN 2.0 Progress Report

CLN 2.0 Progress Report measures progress on the five regional goals since the CLN community set them in 2019. This report reflects the work of local conservation organizations who have worked tirelessly to conserve new lands. It contains scientific analysis and interconnections to state goals and regional planning processes. Read the report >

Survey: Financial & Community Impacts

Survey Says: Federal Orders Are Having Regional Impact In February 2025, we surveyed TOGETHER Bay Area members and partner organizations about the real and potential consequences of recent executive and secretarial orders.

Connecting Urban Biodiversity

In 2022, we launched an exploration that incorporates community science through iNaturalist, and conservation science through the Conservation Lands Network. This project is a collaboration between TOGETHER Bay Area and the California Academy of Sciences, with funding from the State Coastal Conservancy.

This project:

  • Leveraged professional and community science
  • Connected biodiversity and social equity in conservation planning
  • Illuminated baylands and uplands interdependencies

Advancing 30×30 and Other State Goals

We need to accelerate our collective efforts to address the climate crisis, and TOGETHER Bay Area members are positioned to deliver nature-based and equity-centered solutions. TOGETHER Bay Area members are working on local projects that can advance the State of California’s goals as outlined in Pathways to 30×30 and other plans

In the winter of 2022, we surveyed our member organizations and they shared over 110 projects that are ready to implement and which meet the objectives of the Pathways to 30×30 Strategy. Learn more >

Wildfire Data Working Group

As hundreds of thousands of acres of the Bay Area have burned recently in wildfires, our members are in a constant cycle of research and innovation as we learn to live with fire on the landscape. Collecting and analyzing data to support this paradigm shift is key. The Wildfire Data Working Group (WDWG) is focused on regional coordination of data collected before, during, and after wildfires for informed decision making by land management organizations and agencies. TOGETHER Bay Area convenes this working group of data compilers to learn from one another, share information, and build our regional understanding of the impacts of fire on the land.

Partnership with FLAME

FLAME (the Fire-resilient Lands Alliance [for the Management of Everything]) is a regional working group that aims to connect professionals in the greater nine-county San Francisco Bay Area (and adjacent) who delve in fire and natural resource management. With an interdisciplinary approach from individuals working in local fire departments to federal, state, county organizations and the likes, this group will meet to discuss and work through challenging topics regarding fuels reduction and wildfire hazard mitigations, as well as share lessons learned and project successes with on-site field trips.

Since most wildfire-related topics have a planning and data side and an implementation side, the Wildfire Data Working Group and FLAME work in partnership to better serve a broad range of wildfire-related positions by efficiently moving forward a common agenda.
