What is a Marine Protected Area?

A Marine Protected Area (MPA) is simply a protected marine environment. What does that actually mean and how do people interpret it?

The goal of an Marine Protected Area

The goal of a Marine Protected Area is to let the marine environment recover to a state essentially unaffected by humans. It progresses from the affected stage to the unaffected stage, it’s natural stage.  This state depends on where it is geographically and the natural equilibrium it would attain based on what surrounds it. In ecological terms it reaches it’s climax community.

An unpolluted Marine Protected Area will accumulate species that would naturally occur in that environment. Polar species for a polar environment, temperate for temperate etc.  Those species would, when left alone, essentially fight it out amongst themselves. An ecosystem would develop that is the same as an environment where there are no humans.

The goal of a Marine Protected Area therefore is to allow that to happen. That is to leave it alone. To leave it alone implies no harvesting and no external anthropogenic influences.

How to create a Marine Protected Area

Firstly MPAs require a local desire (usually national) to protect the area. Laws sometimes come into effect that impose an obligation to local populations to leave the area alone.

At times, military occupation of an island or archipelago ensures that. The environment is off limits as a result of the entire region being protected for strategic purposes.  e.g. The Chagos islands.

In rare circumstances such as on Bikini atoll in the Marshall islands, nuclear weapon tests meant that the area was off limits for decades due to being  toxic. The depopulated environment recovered despite the initial poisoning.

Once an MPA is announced,  it requires people to be kept out of it. This can be achieved by laws alone. But because people break the law, policing of the area is often required. Severe deterrents to would-be poachers need to be publicized and enforced.

The degree of protection attained is governed by numerous factors and that influences the outcome and overall ecology of the area.

What happens if total protection isn’t attained?

Firstly, total protection is rarely attained. Nowhere on earth is completely free from human influence. Even the very deepest marine trenches are showing signs of human pollution.

What is Pristine?

If “Pristine” is completely untouched (0% human influence) a Marine Protected Area is trying to get as close to zero as possible.

Natural balance

So basically, if you remove one or a significant portion or number of any species, it will have an effect on the entire ecosystem. The ecosystem shifts to compensate for the imbalance.  Ecologists call this Trophic Cascade. Trophic levels are essentially what separate plant from herbivore, herbivore from predator.

So by reducing the numbers of predators, the prey species numbers will increase. This will have an effect on what they in turn hunt or harvest. Once those species populations change that will then change what they influence. Imagine a line of dominoes that spreads out into a web. One influences another which then influences more again. These changes in populations not only affect populations either side of them of them but they can also affect the very chemistry of the environment. If there are more of less plants in a system, there would be more or less Oxygen or CO2 available.

Altering the physical chemistry of a system also causes ecological cascades. Increase or decrease in temperature is like changing it’s geographical location. Adding chemicals will also change ecosystems. Farmers increase productivity of their fields with fertilizers and similarly, plant growth can increase if certain compounds of Nitrogen or Phosphorous are added. A process called Eutrophication. Too many plants and not enough herbivores to eat them means systems can be overrun by plant life, choking and shading what was there before.

Benefits of MPAs

The lack of human harvesting from an MPA means that fish numbers and overall biomass increases. (There are more living things). Eventually the biomass increases to the point where it spreads out into the surrounding waters. This overflow can then be harvested. Within the MPA the fish live longer, breed more often and attain greater sizes which means their breeding potential is also greater. (Larger fish produce more eggs and milt and therefore more babies.)

Harvesting from MPAs

In some parts of the world, MPAs have been established but the local population still harvests from them. This is sometimes for indigenous cultural reasons, however in some locations these cultural excuses are abused and the harvesting is too regular to be sustainable. A overexploitation situation occurs. Local groups citing cultural exception harvest instead of allowing the MPA spillover to repopulate the regular fishing grounds.

The future

In a report from Pew Charitable Trusts: By 2018, there are 15,600 Marine Protected Areas globally, some 25 million square kilometers. This equates to only 7% of the planets oceans. The aim is by 2020 to have 10% of the oceans protected but it seems we are falling well short of this goal. What is worse is that of that 7%, less than half are actually no take zones. Many are still open to harvesting either by indigenous groups or by commercial operations. So it seems we still have a long way to go.

Humans build bigger and bigger fishing boats. The demand for seafood increases with the human population. The pressure on the worlds oceans increases.

It is vital to respect the natural capacity of the oceans. This capacity is not only of the economic kind. How many fish swim in it or how many we can catch etc, but also how well it can recover. Recovery is fastest when the ocean is healthy. A healthy ocean has a greater ability to accept losses, not only amongst it’s inhabitants populations but also losses to it’s own intrinsic health.

Humans are affecting the very chemistry of the worlds oceans.

Natural damaging cycles such as El Nino events are becoming more common. Whilst natural environments before could recover from these warming periods because there was a long time between them. Now these events are happening too regularly for the reefs to fully recover. Each time the damage occurs, the environment has only recovered 50% of it’s potential health. The one step forward two steps back scenario.

The healthiest reef or any environment for that matter is one that is in it’s natural state. This is why it’s so important for us to set aside as much of our Planet as possible. A Marine Protected Area or any conservation area needs to left alone. They should all be left alone and there should be more of them. It is these natural wild spaces that will be the saviors of us all as we strip everything else bare.

The Republic of Palau has a huge variety of healthy and almost pristine ecosystems. Palau provides a huge wealth of opportunities for content. It is visually stunning with tropical islands, coral reefs, jungles and plentiful iconic species.

There are numerous conservation stories available.  Tuna Fisheries, Marine  enforcement,  mangrove protection, migratory shorebirds, climate change resilience.

We have WW2 wrecks, their de-mining and recovery of human remains. Extensive underwater caverns and of course the many marine lakes with their millions of Jellyfish.

Additionally the other side of the coin is also available. Stories on illegal fishing and the black market trade in protected species. The need to balance tourism and development with conservation. Tuna economics, Climate Change, Ocean acidification, renewable energy, coral bleaching….

There are stories waiting to be told and new technologies waiting to tell them with and since we are based in Palau we can start production quickly.

Because of our long experience filming in Palau we can help you organize filming permits, arrange transport, accommodation, rental equipment, interviews and talent.

Whilst things have improved, Palau is still remote and does not have a huge amount of media production resources. There are no dedicated camera stores and spare parts etc need to be ordered in from overseas, which can take at least a week at best.

It’s regional and national government structures can be tricky to negotiate for filming permits and site access. We can help you navigate and succeed in this local arena.

If you are considering filming in Palau it’s well worth contacting us to find the lay of the land and get a bespoke solution for success.

Palau Stock Footage library

If you need footage quickly or something specific but time consuming, there is always the option of stock footage. As a result of filming here for over 12 years we have a huge stock footage library available.

Almost all our work has something to do with the environment. It’s well worth seeing what we can offer in stock footage.
