This e-book records favorite stories about salt marsh secrets that my collaborators and I uncovered while studying southern California coastal wetlands, from the 1970s to date. In 1986, we became the Pacific Estuarine Research Lab.
Please download the files as they appear online and enjoy learning what we learned…and more. You’ll meet many “detectives,” and you’ll be able to appreciate how they learned so much–undeterred by mud and flood. Learn while exploring the salt marshes near you!

Informational Flyer (English)
This report compiles information about the Tijuana River Valley to ensure that all stakeholders involved in the planning process have a baseline understanding of what resources are present within the valley, how the area is managed, and what threatens the long-term sustainability of the natural habitats and built infrastructure. Information in this document has been compiled with input from the CURRV Stakeholder Working Group, providing the foundation for the vulnerability assessment and the development of climate adaptation strategies.
In preparation for conducting a climate change vulnerability assessment, TRNERR convened a scenario planning workshop where coastal geomorphologists, engineers, oceanographers, land use managers, and ecologists delved into how climate change might alter the physical landscape of the Tijuana River Valley. The process and results of the workshop discussions are summarized in this report outlining four potential futures.

CURRV Planning Process
Future Planning Scenarios
Integrating Scenarios into Vulnerability Assessment & Adaptation Planning
A Geographic Information System is a computer system developed to capture, store, manage, analyze and display data that can be linked to geographic information, generating maps as the end product. GIS has been largely used as a tool to answer questions, to solve problems and to help in the decision making process in numerous fields for example, natural resources, about population census, health issues, fire management, urban planning, natural hazards and so forth.
The Tijuana Estuary is a very important ecosystem. Its variability in topography, tidal influence and streamflow results in a nutrient-rich estuary with a diversity of habitats that are home to a wide range of wildlife, aquatic organisms and plants. It has persisted despite disturbance from urban and agricultural land uses. In order to protect and preserve the Reserve, Research is highly necessary to monitor and study the dynamics of the Tijuana Estuary. The Tijuana Estuary’s research and monitoring programs are responsible for collecting data and the research’s GIS Lab stores and manages the data for future analysis and comparisons. Maps are generated according to the needs of specific projects. GIS is not used only within the Reserve, it is also used in projects that include areas like the Tijuana River Valley, South San Diego Bay Salt Ponds and Los Peñasquitos Lagoon. Currently GIS Lab is working with map products for the Climate Understanding & Resilience in the River Valley (CURRV) project, which studies the Tijuana River Valley vulnerabilities to climate change, sea level rise and flood. Another project we are using GIS for is the South San Diego Bay Salt Ponds restoration, which needs map products to analyze elevation and vegetation data of the site, for example.
Some of the data we use, such as operational boundaries, roads, and trails can be accessed through the links below:

Why this Project?
The Tijuana Estuary is one of the largest intact coastal wetlands in Southern California, and a model case study from which to strengthen our collective understanding of wetland management using information from the past, present, and future.
The TIME project is a collaborative project that brings together the perspectives of scientists and managers to address key needs identified by Southern California Wetlands Recovery Project (SCWRP) and the Tijuana River Valley Recovery Team (TRVRT) by developing a decision-making framework. TIME embodies a collaborative approach that, from the project outset, engages stakeholders to ensure development of locally relevant products.
Using information from the past, present, and future
Numerous studies have been conducted to better understand and restore coastal wetlands in Southern California. The TIME project seeks to explore several essential elements to support effective wetland recovery at the Tijuana Estuary, with an eye on scaling up to the region:
1. Understand stakeholder needs through an issues assessment and communicate lessons learned from synthesizing information from the past, present, and future at the Tijuana Estuary that can inform wetland restoration under changing and uncertain conditions;
2. Characterize ecosystem services provided by coastal wetlands in southern California and how they may change over time;
3. Incorporate information gained from historical ecology studies; and
4. Create visualizations to assess historical and future potential characteristics of the Tijuana River Estuary.
The TIME project is designed and carried out by a diverse team of collaborators that include applied science and collaboration professionals, and the specified end-users of TIME’s products. Collaborators work together to iteratively incorporate stakeholder feedback into the development of each project phase.
