Nearly 2,000 Volunteers Just Answered the Ocean's Biggest Question

0:00 For more than 10 years, almost 2,000 people have been walking California beaches with a clipboard. They're not looking for shells. They're not looking for lost dogs. They're counting strangers. Every surfer, every kid in a tide pool, every person with a fishing rod, every kayak, all of it tallied one beach walk at a time. And here's the strange part. The pile of clipboard data, more than a million little tally marks, just answered a question that scientists have argued about for decades. Do marine protected areas actually work? Not just on paper, in the real world with real people. Today, we are going to walk one of those beaches with them, and we're going to find out what all of that counting revealed.

0:42 You're listening to the How to Protect the Ocean podcast, and I'm Andrew Lewin. This is the show where we take one ocean story a day and turn it into something you can actually do every weekday, Monday to Friday.

So let's start with the question underneath the whole episode. When you hear the words marine protected area, what do you picture? Probably a line on a map, a stretch of coast where the rules are different.

1:26 Maybe no fishing, maybe not taking anything at all. Okay, but a line on the map does not protect anything by itself. A rule only matters if people follow it, and that raises a question almost nobody asks. Who is actually checking? Who is standing on that beach day after day, seeing whether people obey the line? And if we did check, what would we find? Would we find a quiet compliance, or would we find that protected is just a word we put on a sign and hope for the best? For most of the California coast, for most of history, the honest answer was nobody really knows. Nobody was counting. Until a group of volunteers decided to change that.

2:09 Here's the scene. It was a bright Friday morning on the California coast. A volunteer parks, grabs a data sheet and a pair of binoculars, and walks down to a fixed starting point on the sand, the same starting point every single time. Then they begin to walk a set path along the shore. As they go, they count. Not everything at once. They count in categories: people swimming, people surfing, people walking dogs, people tide pooling, people fishing from the rocks, boats offshore. They note the weather. They note the tide. They write down the time of day. It sounds pretty simple. It sounds almost too simple to matter.

2:49 But now multiply it. This is a statewide program called MPA Watch. It runs through a network of about a dozen local organizations from near the Oregon border all the way down to the Mexican border. And when researchers pulled the archive together for this new study, the numbers were staggering. Almost two thousand volunteers, more than thirty thousand separate beach surveys, over one hundred sites up and down the coast, both inside protected areas and outside them. And more than 1.2 human individual activities all counted by hand between 2012 and 2020. Let that sink in. 1.2 million tally marks made by regular people on their own time because they cared about the water in front of them.

3:35 And it is not always calm work. A reporter recently joined one of these teams on a boat survey off La Jolla near San Diego. On that single trip, the crew spotted three vessels that appeared to be fishing illegally inside a no-take zone. They logged the locations by radar and sent them straight to state wildlife authorities. The statewide coordinator put it plainly, "This program is basically California's only way to know what human activity is actually happening on the beach." Those are the eyes on the coast. Now, what did all those eyes see? Here's where it gets really good. The researchers did not just add up the tally marks. Volunteer data is actually pretty messy. People survey at different times, in different weather, with different skills.

4:18 So the team used careful statistical models to strip out the noise. They controlled for the tide, the season, the day of the week, the weather, the type of beach, all of it. They wanted the real signal, not just the busy weekends. And when the signal came through, it told a clear story. Three parts. First finding. The first finding inside the strictest protected areas, the no-take zones where you are not supposed to remove anything, the amount of fishing and collecting was significantly lower than outside. Compliance, in other words, was pretty high. Across the whole state, the vast majority of what people were doing broke no rules at all. The line of the map was mostly being respected. The second finding, and this one matters just as much, protection did not ruin anyone's fun.

5:02 People were swimming, surfing, diving, and walking the beach inside protected areas at the same rate as everywhere else. There was no measurable drop in recreation. So the fear you sometimes hear that protecting the ocean means locking people out of it, the data simply didn't support that. You protect the fish, and people still get their beach day, both things at once. And the third finding, the coast is overwhelmingly a place people go to enjoy, not to extract. Take one busy Southern California beach the study modeled. On one nice day, the model predicted around four hundred and fifty people out there. And of all those people, only a small handful, fewer than five, were there to take anything at all. Everyone else was just living their life next to the sea.

5:44 So put those three things together. People are mostly following the rules. Protection is not costing our recreation, and extraction is the exception, not the norm. That is a genuinely hopeful picture, and we only know it because somebody counted. This is why a quick pause here. If you are finding this useful, the best thing you can do right now is share this episode with one person who loves the ocean. Just one. That is how this show grows, and it costs you nothing. Okay, because there's one more layer here, and it is the layer that ties everything together. You might be thinking, fine, but counting people is not counting fish. How do we know the protection actually is helping the ocean, not just the beachgoers? That's a fair question, and this is where the human data meets the underwater data.

6:28 For years, separate teams of scientists have been diving California's protected reefs, measuring the fish. In twenty twenty-two, the state pulled ten years of that work together in a big review. The result across the network, fish inside the protected areas were more abundant, larger, and greater in total mass than fish in comparable areas open to fishing. The effect was strongest exactly where you would expect, in places under heavy fishing pressure and in the larger, older reserves that had no time to recover. Now, why does that recovery happen? Because people leave fish alone, which brings us right back to the clipboards. Think of it this way. The dive surveys tell you what is happening underwater. The beach counts tell you why.

7:09 And if the fish are coming back, the human data can show you that it is because people are actually honoring the no-take zones. One data set without the other is only half the story. Together, they close the loop. And when protection is real and enforced, the payoff can be spectacular. There's a famous example just south of California in Mexico a place called Cabo Pulmo. Local families fought to turn their overfished reef into a strictly protected no-take park and then actually defended it. Within about a decade, the total mass of fish on the reef grew more than four times over a jump of roughly four hundred and sixty percent. Big predators, the sharks and groupers, came roaring back.

7:50 It became one of the most dramatic ocean recoveries ever measured. The difference is not magic. It's enforcement and a community that showed up. That is the thread running through this entire episode. Protection on paper does nothing. Protection that people believe in and follow and watch over brings the ocean back. And the only reason we can prove people are following it at the scale of an entire coastline is that a couple of thousand volunteers kept walking the beach and counting. So here is the big idea I want you to walk away with. We tend to think ocean recovery is something that happens far away, done by experts in wetsuits and research boats. And that work is real, and it does matter. But this study is a reminder that a huge piece of it is because of just ordinary people, people with a clipboard and a free morning doing something small over and over for years.

8:39 That patience became one point two million data points, and those data points became proof, proof that California's ocean protections are working and that people are largely respecting them, and that we did not have to give up the coast to protect it. The ocean is not only saved by heroes, it is saved by people who just show up, which means you can be one of them. Let me give you a few real options here. Nothing here is going to single-handedly save the ocean, and I am not gonna pretend otherwise. Each one is a genuine, honest contribution. One, if you are anywhere near the California coast, you can literally do what this episode is all about. MPA watch trains everyday volunteers to walk these surveys. You do not need a science degree.

9:21 Go to mpawatch.org and find a program nearest you. A few surveys a month at your own pace around the tides. That's the whole commitment. Two, wherever you live, learn the local rules before you go. Find out where the nearest protected area is and what it actually allows. Some zones let you fish, some let you take nothing. Knowing the line and respecting it is one of the most direct things that you can do. And third, the beach walk classic. Grab three pieces of trash every time you leave the coast. Volunteers in this very program call it the three of the sea. It is small, but it adds up Four, if you see something that looks like poaching inside a protected zone, you do not confront anyone.

10:03 You report it. In California, that goes to the Department of Fish and Wildlife tip line. Like those volunteers off La Jolla, your job is just to be a witness. Collecting the observation is enough. And five, share what you learned today. The finding that protection works and that it works without shutting people out is exactly the kind of thing people need to hear about right now. So pass it on. That's it for today's episode.

And to be honest, like, I really just appreciate you listening each and every day, each and every weekday that I publish, Monday to Friday. It's something that I really enjoy. It's kept me connected to the ocean.

10:45 I'm a science communicator who works for a company called Pisces Oceans, and I just love doing this kind of stuff. This is something that I will always do, and this is episode 1978. 1,978. It was actually the year I was born, in 1978. Yeah, I'm old. It's okay. But I love this stuff. I really love the fact that you're listening. If you have any suggestions on this type of format that I'm doing, 'cause it's a little bit different than I've done before, I would love to hear your thoughts. Please let me know. You can DM me on TikTok, on Facebook, on Instagram, whichever one you prefer. Or you can go to speakupforblue.com/patreon, and you can support the show if you really love it that much. I appreciate you listening. This has been another exciting episode of the How to Protect the Ocean podcast. I'm your host, Andrew Lewin.

11:25 Have a great day. We'll talk to you next time, and happy conservation.
