The 2023 Sediment Management Work Plan, prepared for the City of Imperial Beach, is intended to serve as a guide for agencies and organizations responsible for sediment management activities in the Tijuana River Valley (Valley). The recommendations presented in this Work Plan are intended to support successful implementation of sediment management projects throughout the Valley […]
Publications coming out of PERL, led by Dr. Joy Zedler.
StoryMap documenting impact and potential recovery of riparian forest associated with the invasion of shot hole borer beetle, expansion of the invasive plant Arundo donax, channel movement and erosion near the Naval Outlying Landing Field Imperial Beach (NOLF IB), and changes in salt marsh near the river mouth.
Detailed report of future scenarios developed through the Climate Change in the River Valley (CURRV) process.
This document outlines approaches to monitoring a wide variety of parameters of interest in Southern California wetlands, and includes protocol documents and implementation recommendations.
The Divided Together podcast was created to help visitors explore Border Field State Park and learn about it’s origins. Each episode showcases the park through a unique perspective that ties the land to its people.
This e-book records favorite stories about salt marsh secrets that Joy B. Zedler and her collaborators uncovered while studying southern California coastal wetlands, from the 1970s to date.
Check out the newest book on the history of habitat restoration in and around the Tijuana Estuary, by Chris Nordby.
A pioneering study published in Biological Conservation examines the ability of tidal marshes throughout the nation to keep pace with rising seas, conducted by the National Estuarine Research Reserve System. Visit the NERRA website for the full report.

The official TRNERR management plan, developed as part of the Reserve’s role in implementing the federal Coastal Zone Management Act.
Led by the San Diego Regional Water Quality Control Board, this is a concise summary that outlines both the problems and potential solutions facing the River Valley.
The CURRV project assessed the potential local effects of climate change associated with sea level rise and flooding from the Tijuana River, and a high-school artist, Audrey Carver, painted murals that helped visualize four different possible futures that scientists developed.
Discover how the Tijuana River National Estuarine Research Reserve and its partners embraced uncertainty and used scenario planning to assess climate vulnerabilities in a highly complex socio-ecological system.

Climate change effects such as sea-level rise (SLR) are altering California’s coastal wetlands, and this USGS study used physical and biological data to project how SLR may alter these ecosystems in the future.
A synthesis of hundreds of historical resources were used to reconstruct the ecosystems of the Tijuana River valley prior to major European-American landscape modification and compare them to those found today. View the Tijuana River Valley Historical Ecology Investigation
