Transforming Ocean Conservation in California

TRANSFORM FISHERIES

PARTNERING WITH FISHING COMMUNITIES TO IMPROVE OUR FISHERIES AND OCEAN HEALTH

In California, our Fisheries Team is focused on solutions for healthy ocean ecosystems and thriving fisheries.

Some of the greatest threats to ocean ecosystems stem from poorly managed fisheries. Fisheries provide a food source for 3 billion people and directly employ over 30 million fishers worldwide, but sustainability is limited by problems that produce threats like overfishing, bycatch and habitat destruction. In California and around the world, limited public funding, capacity and data are straining outdated management models in meeting their objectives—particularly in a changing climate.

We have found that the people best positioned and motivated to restore ocean health are the ones that depend on it most: fishing communities. We work with fishermen and community leaders motivated to improve their fishery and match their expertise with our team’s cutting-edge science, technologies and unique experience. Together, we apply adaptive, cooperative management and develop innovative climate-ready fishery solutions that can better support healthy oceans, healthy fish populations and resilient fishing communities. 

Our efforts in California have resulted in breakthroughs that have helped rebuild fisheries, secure coastal jobs and sustain important sources of seafood.

Through this work, we are advancing climate-ready fisheries management by working closely with partners, testing innovative solutions on-the-water, modernizing California’s data collection methods and management frameworks and influencing transformations around the world to support human wellbeing and ocean health.    

Filling the Data Gaps

One of the biggest challenges facing sustainable fisheries is the lack of information necessary for responsible management. These information gaps mean that managers, fishermen and consumers are less informed and may be more likely to put ocean ecosystems at risk. One of the best ways to address this challenge is to work directly with fishermen, communities and management agencies to build the tools and technology needed to allow fishermen to share real-time catch data with each other and with scientists and managers. We are filling these data gaps by conducting collaborative research with fishermen, academic and agency partners to address key data needs in our priority fisheries.

Transforming Fisheries Management

When fishermen participate in the management of their fisheries, it results in better solutions that support healthy, productive fisheries. By working directly with fishermen to build new tools and engage in demonstration experiments on the water, we are supporting new partnerships to ensure policy changes are informed by science and experience.

Our vision is to transform California’s fisheries, their ecosystems and the communities they support so that they are resilient to a changing climate by revolutionizing how they are managed. Success in California can then be replicated across more fisheries and ocean areas to deliver healthier ocean ecosystems and sustained benefits to people around the world.    

RECOVER KELP FORESTS

RESTORING AND PROTECTING KELP FORESTS IN A CHANGING OCEAN

California’s incredible kelp forests are a critical ecosystem that is more productive than the Amazon rainforest. A breeding ground for more than 1000 species, they act as a protective blanket for our iconic beaches and have an immense impact on jobs and revenue for our state.

But a perfect storm has destroyed 96% of kelp forests on California’s North Coast.

The combination of warming ocean temperatures and a deadly virus has led to the die off of the sunflower sea star, which has set off a chain reaction resulting in massive loss for kelp. Sunflower sea stars eat purple urchin, and without enough sea stars, the urchin population has exploded to 60 times its usual size. Purple urchin feed on kelp and this ballooning population has eaten its way through much of the kelp forest, resulting in what could be permanent damage to the ecosystem if we don’t find a way to rebalance these species.

Climate-driven changes like those on the North Coast are leading to a massive die-off of kelp forests not only in California, but in places like Australia, Norway and Chile. TNC is committed to leading the way to address this global conservation threat by advancing solutions for protecting kelp forests in California and around the world.

RESTORATION AND ACTION TO PROTECT KELP FORESTS

TNC has experience in restoring millions of acres of forest habitat around the world—and now it’s time to save our ocean forests. With the help of diverse partnerships, we’re launching an ambitious effort to recover kelp at a speed never seen before. We’ve broken this plan into three key components.

1. Research: To understand the extent of the problem, we conducted the largest known marine drone mapping survey in California history. Our team was the first to identify accelerating losses of kelp on the North Coast. In just three short years, from 2016 to 2019, we lost an additional 85% of our remaining kelp. If this trend continues, we are at risk of losing our kelp forest altogether.  
2. Reset: By reducing the urchin population, we can make way for kelp to recover. To give nature a boost, we’ve developed a captive breeding program for the sunflower sea star, the purple urchin's main predator, to safeguard against their loss. Ultimately, we’ll reintroduce the stars to rebalance the ecosystem and keep urchins in check. We’re also supporting the development of an urchin ranching industry that turns purple urchins into valuable seafood, incentivizing their harvest by creating a new market.
3. Restore: For the first time, we’re developing a spore bank for bull kelp in order to capture the biodiversity of California’s kelp before it’s gone. The spore bank will house genetic samples as a seed source for restoring healthy and resilient kelp forests in the near future.

With this initiative, we are working to ensure that kelp forests here in California and around the world continue to support the incredible biodiversity and healthy coastal marine ecosystems on which both nature and people depend.

BUILD ISLAND RESILIENCE

Islands are remarkable features of our planet. While representing only 5% of the Earth’s land area, islands host extraordinary concentrations of unique species. They’re also key features of healthy marine ecosystems and support the health and livelihoods of communities across the globe.

Unfortunately, islands are also extinction hotspots—a trend driven largely by invasive species and exacerbated by climate change. These biodiversity losses reduce the capacity of islands to recover from threats in a changing world.

Yet islands give us hope. Conservation action has led to remarkable recovery stories on TNC’s Santa Cruz Island and Palmyra Atoll Preserves, giving us the opportunity to think bigger and leverage this foundation of success. 

We’re making an impact three ways:

• We’re working with partners to explore opportunities for scaled conservation wins across geographies including all US islands and atolls in the Indo-Pacific.

• We’re demonstrating the opportunity and success rates of proven solutions for islands around the globe, like seabird restoration and invasive mammal eradication. We’re also solving for currently intractable challenges, like avian diseases spread by mosquitos with the Birds, Not Mosquitos partnership.

• We’re enabling solutions at key locations like TNC’s Santa Cruz Island and Palmyra Atoll Preserves to both strengthen the resilience of these special places and demonstrate successful approaches that could be applied elsewhere. Powerful examples include “seabird discotheques,” social attraction beacons that are being used to reestablish these charismatic species and their critical role in island ecosystems, and the translocation of the sihek (Guam Kingfisher).

As global thought leaders, we are making big conservation visions into conservation realities working with partners on islands worldwide. From the birds flying through the sky to the native plants reestablishing themselves to the coral reefs, we are helping island ecosystems recover and thrive. 

FIGHT PLASTIC POLLUTION

ACCELERATING CORAL RESTORATION

A Threatened Ecosystem

Coral reefs cover less than 0.1% of the ocean floor, but they support 25% of all marine species. Coral reefs are also essential to many coastal economies, and they help protect the world’s coastlines from dangerous storm surges. At least 500 million people globally rely on coral reefs for food, coastal protection and their livelihoods. In the U.S., annual flood protection benefits and tourism revenue provided by coral reefs amount to more than $4 billion.

Yet coral reefs are also among the most threatened ecosystems on Earth due to climate change and increasing local threats like overfishing, coastal development and pollution. In the last three decades, the world lost 50% of its coral reefs. If we stay on this destructive path, up to 90% are projected to disappear by 2050.

Reducing Cost

• Our Oceans Team is collaborating with engineers to develop technological solutions to automate the coral growing and outplanting process to radically reduce the cost of coral restoration.
• We are setting up semi-automated, high-capacity coral farms that can produce millions of corals per year.

Increasing Funding

• We are working with partners in academia and the financial industry to identify non-traditional funding sources and mechanisms that can leverage funds from reef beneficiaries such as the tourism industry and coastal property owners.
• We are exploring how we can harness existing hazard-mitigation funding and investments in coastal protection infrastructure to restore coral reefs.

Improving Outcome

• We are working with our colleagues in the Caribbean and the Coral Restoration Consortium to develop an online coral restoration database that allows for easy sharing of restoration project outcomes across the globe. This will help us understand the drivers of success in coral restoration.

With the engineering team, we are developing tools to facilitate the tracking of corals in nurseries and post outplanting. This will help us adjust the nursery conditions and pick outplanting sites that maximize the survival of outplanted coral.
