Border Field State Park: Divided Together App is LIVE on Apple and Google! The Podcast series has been launched!

The Border Field State Park: Divided Together app is live on Apple and Google. The app is a self-guided tour with highlights of the Divided Together podcast (coming soon) and is meant for high school age and up. There are currently three stops to the tour, with more coming: Kumeyaay Nation Divided by the Border, Indigenous Land Use Practices, and Scientists and Geographers Working Across Borders.

Each stop is geopositioned around the turf on Monument Mesa. It has text, quotes, and an audio excerpt from the podcast. 

You can find the app on Apple or Google by searching for “Border Field State Park.” Before you come to the Park, it is recommended that you download the app, then download the tour (1 MB). If not, you can download the app closer to the entrance of the park, where there is better service. We recommend this because the service can be spotty on Monument Mesa.

Alternatively, you can also use the web app https://borderfieldsp.stqry.app from any device that has access to the internet.

This is the ancestral land of the First People, the Kumeyaay.

In 1917 during World War I, there was concern among Quakers- a largely religious group of people – to find ways to serve without joining the military or taking lives.

The American Friends Service Committee quickly established itself as an organization for humanitarian relief and social change. They were also in direct contact with the U.S. military discussing how to move forward with conscientious or religious objectors to war. This was in direct response to the military’s inconsistency in dealing with religious objectors during previous periods of conflict.

Over time, the American Friends Service Committee’s reputation grew. In 1947, they were awarded the Nobel Peace Prize and since then have worked with groups from all backgrounds and cultures around the world to promote a world free of violence, inequality, and oppression. Here in the Southern California border region, this work largely focuses on immigration and humanitarian concerns.

In this episode we’ll hear how the American Friends Service Committee has had an impact on the border region and the lives of those involved in the work they do.

Episode 3: Indigenous Land Use Practices

Listen here

This is the ancestral land of the First People, the Kumeyaay.

As climate change continues to wreak more havoc both locally and abroad, how we manage land will become more of a significant factor in protecting the planet’s resources. However, here in California, we don’t have to look far to find ways to accomplish that. 

For thousands of years, the Kumeyaay have implemented land management practices to both protect and enhance resources and productivity of the land, whether it’s for food or medicine or other raw materials. To this day, some of those traditional practices are still in use. This ranges anywhere from building rock walls to utilizing controlled burns.

In this episode of Divided Together, we’ll hear from two members of the Kumeyaay Nation and how their ancestors have used the land’s resources to benefit both the land and the people, as well as why these practices are necessary in our increasingly changing climate.

This episode closes with a special twenty-seven-year-old recording of the late San Jose de la Zorra elder, Gloria Castaneda, describing the juncus collecting song. Audio courtesy her daughter, Ana Gloria Rodriguez.

This is the ancestral land of the First People, the Kumeyaay. 

In 1982, the Tijuana River National Estuarine Research Reserve was established. Its goal was, and still is, to enhance scientific collaboration and research within the watershed that is split between two countries, Mexico and the United States. Three quarters of this massive water basin lies in Mexico, making this collaboration even more necessary and important. 

Over time, various research partnerships were created to study erosion, sedimentation, and tropicalization. More recently, geography professors have studied erosion and sedimentation in Los Laureles Canyon in Tijuana, a sub-watershed that flows right into Border Field State Park. When it comes to the ocean, tropicalization is another significant collaboration topic. 

In this episode we’ll hear from some of the geographers and scientists working back and forth across the border, some of the challenges and rewards they’ve encountered, and ways to make studying this landscape and marine environment more accessible.

Episode 1: Kumeyaay Nation Divided by the Border

Listen here

Ana Gloria Rodriguez, Kumeyaay from San Jose de la Zorra, Mexico from the “Kumeyaay Nation Divided by the Border” episode.

This is the ancestral land of the First People, the Kumeyaay. 

When the border between the United States and Mexico was established in the 1850s, the land of the Kumeyaay was split between the new American state of California and northern Mexico. People and culture were immediately divided. In the over 170 years since, the effects on the culture and land management have become evident.

In this first episode of Divided Together, we’ll hear from a respected member of the Kumeyaay Nation, Ana Gloria “Martha” Rodriguez. For nearly 20 years, Martha and her family have been important stakeholders for California State Parks in San Diego County, often sharing cultural knowledge and providing invaluable feedback on proposed projects. She and her husband, Dr. Stanley Rodriguez, participated in our Fiesta del Rio event for ten years. They both run the Kosay Kumeyaay Market in Old Town San Diego State Historic Park. We’ll hear how this border has had an impact on the people and the land over the centuries, and we’ll hear what Martha is doing to help prevent further erosion and maintain the Kumeyaay way of life and spirit.

40 Years of Restoration at Tijuana Estuary: Lessons Learned

Hot off the press! Check out the newest book on the history of habitat restoration in and around the Tijuana Estuary, by Chris Nordby. 
 
SELLER’S NOTE: Many stressors have been identified by resource managers and scientists at Tijuana Estuary. Measures have been implemented to control and reverse their effects on the ecosystem. This report summarizes restoration activities and lessons learned during the last 40 years as they may inform future restoration efforts and resource management decisions.
 

DESCRIPTION: Tijuana Estuary, located in the southwestern corner of the continental U.S., has a complex history; ecologically, politically and geographically. While the estuary is located entirely within San Diego County, three fourths of its watershed is within Mexico. Each of many stressors have been identified by resource managers and scientists who work at Tijuana Estuary and measures have been implemented to control and reverse their effects on the ecosystem.

The objective of this report is to summarize restoration activities at Tijuana Estuary during approximately the last 40 years (1976-2016) with an emphasis on the lessons learned as they may inform future restoration efforts and resource management decisions. The intended audience includes resource managers and regulatory agencies, the Tijuana River Valley Recovery Team, Tijuana River National Estuarine Research Reserve staff, future funding agencies and the general public. This report will also serve to memorialize a comprehensive list of restoration projects in a single document.

Marshes on the Margin

Developing Tidal Wetlands Adaptation Strategies in Southern California

Through the  Marshes on the Margin we are investigating how the dynamic and heavily altered estuaries of Southern California will be affected by sea level rise. Project partners are also working to identify nature-based conservation and restoration strategies to mitigate the impacts of sea level rise, and will share the tools developed with local stakeholders and coastal managers.

Why we care

Historically, approximately 98 percent of tidal wetlands in Southern California were intermittently open to tidal action. The diverse and seasonally varying habitats provided by intermittently open estuaries serve a wide variety of estuarine species. However, very few estuaries in Southern California still exhibit natural cycles of intermittency, and many are managed as permanently open systems either through construction of jetties, or through dredging.

The conversion from intermittent dynamics to permanently open leads to a reduction of habitat diversity in the region and a reduction in the support of certain NOAA trust species, such as tidewater gobies and juvenile steelhead. Wetlands around these estuaries also host a number of endangered and threatened plant and animal species. Very little data and understanding exists about intermittently open estuaries in Southern California, and resource managers frequently need better information to make management decisions. Because the patterns of opening and closure in tidal wetlands is likely to change with rising sea levels, we have an opportunity and a need to rethink management of these systems, and to better understand the trade-offs between various management scenarios.

What we are doing

Our project will have four stages: 

  • Identifying the vulnerability of intermittently open estuaries,
  • Developing natural and nature-based adaptive strategies
  • Implementing these developed tools at case study sites, and
  • Leveraging existing coastal management networks to share outcomes and promote management solutions that rely on natural and nature-based features.

First, the project team will model and analyze the vulnerabilities and response of intermittently open estuaries and tidal wetlands to sea level rise. Next, the team will identify opportunities for natural restoration through construction of nature-based features. The tools are being applied at four wetland systems in Southern California, including:

  • Goleta Slough (Santa Barbara County)
  • Los Cerritos (Orange and Los Angeles Counties)
  • Los Peñasquitos Lagoon (San Diego County)
  • Tijuana River & Estuary (San Diego County)

Finally, the project team will leverage existing scientific, management, and practitioner networks, developed through the Southern California Wetlands Recovery Project, to gain input during the project’s product development stage and to promote inclusion of natural and nature-based features in the wider range of adaptation strategies available to coastal managers. These steps are expected to improve the number of tools available for managing intermittently open estuaries in Southern California.

Project partners include the California State Coastal Conservancy (South Coast Region), Climate Science Alliance – South Coast, Point Blue Conservation, San Francisco Estuary Institute, Southern California Coastal Water Research Project, Tijuana River National Estuarine Research Reserve, U.S. Geological Survey, University of California- Davis, and University of Southern California Sea Grant. This project builds on the collaborative work of the Southern California Wetlands Recovery project partnership, and  is funded through NOAA’s funded through the Ecological Effects of Sea Level Rise (EESLR) Program.

Engagement at case study sites

Introductory meetings are being held at each individual case study site and are designed to ensure:

  • Marshes on the Margins project team better understand each specific site and stakeholder needs
  • Stakeholders understand Marshes on the Margins project and approaches
  • A shared understanding of the use of each site as a case study site is developed

Meetings have included:

  • Los Peñasquitos Lagoon (San Diego County) – March 21, 2018
  • Los Cerritos (Orange and Los Angeles Counties) – June 4, 2018

Management Transition Advisory Group (MTAG)

The MTAG is made up of Southern California wetland resource managers who have unique knowledge of local wetlands, and additional key stakeholders, including local government representatives, whose decisions directly affect the resilience of wetlands in the face of climate change and sea level rise.

Transition Zones & the Future of Restoration

August 14th | Metropolitan Water District, 700 Alameda St. Los Angeles, 90012

Objectives

  • Increase understanding of transition zones and resilience, and their role in the Regional Strategy Update (RSU).
  • Increase understanding of different local transition zone types, and in the context of sea level rise, what future opportunities exist and solutions are viable for each type.
  • Discuss opportunities, challenges, and priorities of implementing different management measures that restore transition zones.

Tijuana River Mouth Dredging Project

The Tijuana Slough National Wildlife Refuge (Refuge) plans to relocate sand from the mouth of the Tijuana River over the weekend on Saturday, March 10 and Sunday, March 11, 2018. Up to 8,000 cubic yards of beach sand will be excavated from the river mouth using heavy equipment. Sand will be transported by trucks and redeposited along the existing low sand dunes south of Seacoast Drive.

The beach will be closed to the public approximately ½-mile south from the end of Seacoast Drive to the river mouth. The closed area will be delineated in the field. In the interest of public safety, we ask all members of the public to avoid the closed areas.

Biological and Kumeyaay cultural resource monitors will be present during construction. The nesting season for the western snowy plover, a federally threatened bird, is approaching, and Refuge biologists will ensure minimal impacts to plovers or other sensitive species will occur from the project.

The Refuge obtained a five-year permit from the U.S. Army Corps of Engineers to allow dredging and related inlet maintenance at the Tijuana River mouth to maintain an open inlet and facilitate tidal exchange. The permit would allow inlet maintenance dredging of up to 10,000 cubic yards per year of sandy material that would be beneficially used to enhance the existing barrier sand dune system.

The mouth of the Tijuana River is highly susceptible to closure due to the condition of the estuarine tidal prism and the movement of imported and native sand on the beach. The most recent closures occurred in March – April of 2015, May and September of 2016, and April 2017.

The proposed project for March 10 and 11, 2018 is intended to reduce the likelihood that the river mouth will close to tidal circulation during the upcoming 2018 nesting season for the threatened western snowy plover, endangered California least tern and light-footed Ridgway’s rail, and many other species.

We apologize for any inconveniences over the weekend as a result of this project.
