Editor’s Note: In June 2018, US President Donald Trump issued Executive Order 13840 Ocean Policy To Advance the Economic, Security, and Environmental Interests of the United States. This executive order formally revokes Executive Order 13547 Stewardship of the Ocean, Our Coasts, and the Great Lakes, issued in July 2010 by former US President Barack Obama. MEAM interviewed Sarah Winter Whelan, director of the American Littoral Society's Ocean Policy Program and Healthy Oceans Coalition, about what these changes mean for ocean planning in the US, including existing regional ocean plans.
OCTO recently launched two new podcasts called OCTOPOD and Salish Shes.
Both are perfect for your morning commute!
We would love to hear your thoughts on these so please rate and comment on the episode pages.
Scientists now recognize that ecosystems can sometimes undergo abrupt, dramatic changes in response to human use or environmental conditions. When a tipping point like this is crossed, we can witness upheaval in ecosystem structure and function and in ecosystem benefits to people. These tipping points can be hard to reverse due to feedbacks that reinforce the new state.

Protected areas in Central America showcase the region’s magnificent landscape and tropical biodiversity – terrestrial and marine. They help maintain a sustainable supply of water, food, and other natural resources essential for all life in the region. And they provide Central America’s inhabitants a way to protect their own economy, welfare, and future.

As more countries designate MPAs in their territories, the International Union for Conservation of Nature (IUCN), which for over 70 years has been the global authority on the status of the natural world and the measures needed to conserve it, has recently provided clarity to help countries more accurately report their MPAs to the World Database on Protected Areas (WDPA).

It is time to challenge private and public sectors to direct funding resources to operate our protected areas. I am encouraged here at the ECLSP: we are on the forefront of setting standards in operating financially sustainable national parks, including eventually across The Bahamas’ national system of 32 sites. This is the future for protected areas.

Relationships built on trust between MPA management and stakeholders can strengthen community support for MPAs. By fostering such support, these relationships can help MPAs meet their management goals.
Ideally the relationships extend broadly through local communities, resource users, and MPA managers and related agencies. Building relationships early and consistently across these groups can be a relatively simple, productive, and positive experience. Here are useful strategies we’ve observed from managers:
Researchers rely on statistics in their work and p-values are a commonly used statistical tool, including in fisheries and marine conservation science (among many other fields). P-values are widely interpreted as a way to determine the probability that a null hypothesis is true or false. A p-value less than 0.05, for example, is often taken to mean an experiment’s findings are “significant” and the null hypothesis should therefore be assumed false.

Large meteorite lands in MPA
Add this to the tasks of an MPA manager: What do you do when a large meteorite lands in your MPA? The Olympic Coast National Marine Sanctuary (OCNMS), off the Pacific coast of the US, asked that question in March 2018 when a two-ton space rock flew into Earth’s atmosphere, became a giant fireball, broke up into countless pieces, and crashed into the MPA’s waters. The impact was detected on seismometers nearly 3000 km away.
