What is a Marine Protected Area (MPA)?

“A marine protected area (MPA) in the ocean is similar in concept to what a national park is on the terrestrial environment.” Shifting Baselines

There are many terms that mean ‘MPA’, including: sanctuaries, parks, preserves, or natural areas. All of these areas have some boundary in the oceans and are protected by either the Department of the Interior (National Park Service) or the Department of Commerce (National Ocean Atmospheric Administration).

Not all MPAs are completely closed off for human use. Each MPA has various characteristics delineated to it based upon the best circumstances for various stakeholders.

The characteristics are 1) conservation (natural, cultural and/or sustainable), 2) protection level (zoned, zoned with no-take areas, uniformed, no take, no impact, or no access), 3) permanence of protection (permanent, conditional, or temporary), 4) constancy of protection (year-round, seasonal, or rotating), 5) ecological scale of protection (ecosystem or focal resource).

Cape Hatteras, N.C. was the first marine protected area established in 1975.

MPAs are not new management tools but are gaining new momentum as a conservation tool. Watch this PSA with folks from Scrubs, January Jones, and Pierce Brosnan about supporting MPAs off California.

Why are some animals ‘wallflowers’ and others are ‘social butterflies’?

An animal has many reasons to behave more like a ‘wallflower’ vs. a ‘social butterfly’. Some of the more universal reasons to lean to one behavior more than the other would be 1) habitat, 2) predators or 3) availability of food.

For instance, river dolphins (pictured right) typically are solitaire animals because their habitat is smaller than that of the bottlenose dolphins that live in the open ocean. Bottlenose dolphins are highly social animals. Living in a group works to their benefit in the open ocean. A group can be more aware of predators that are nearby and they are able to work together to gather food. Food is rather tough to gather if you are just one mid-size animal in the expansive sea.

Love Our Blue

In honor of National Wear Blue for Oceans Day this January 13, 2010 here is a little ditty to get you amped … Lyrics amended from the song “Love Me Do” written by the brilliant John Lennon and Paul McCartney of The Beatles.

Love, love our blue.
You know we love blue,
We’ll always be true,
So please, love blue too.
Whoa, love our blue.

Love, love our blue.
You know we love blue,
We’ll always be true,
So please, love blue too.
Whoa, love our blue.

Some blue to love,
Some sea so  blue.
Some blue to love,
Some sea so blue.

Love, love our blue.
You know we love blue,
We’ll always be true,
So please, love blue too.
Whoa, love our blue.

Love, love our blue.
You know we love blue,
We’ll always be true,
So please, love our blue.
Whoa, love our blue.
Yeah, love our blue.
Whoa, oh, love our blue.

Answers to “Test your knowledge of sea stars”

Answers to “Test your knowledge of sea stars” from December 31, 2009.

True or False: Sea stars are fish. They are echinoderms, a group of invertebrates. Invertebrates have no backbones. All fish have backbones.
True or False: Sea stars are closely related to sea cucumbers, sea urchins and brittle stars.
True or False: Sea stars have a flexible skeleton.
True or False: Sea stars breathe through gills. They breathe through a water vascular system. You can see the tube feet (a main component of the water vascular system) on the underside of the sea stars.
True or False: Sea stars can regenerate most body parts.

Congrats to all those that got them correct!

A plea of the manatee

In early 2009 the Florida Fish and Wildlife Conservation Commission (FWCC) reported that there was a significant increase in the population of the West Indian Manatee (Trichechus manatus), a marine mammal. Almost a year later it was reported that there was a record number of deaths of manatees.

Even though the FWCC pointed out that there may have been more manatees reported in the 2009 populations since the count was done after several cold fronts had clustered the manatees together, was there too much confidence in the public after hearing the news that the public didn’t think they had to participate in best practices to save the manatee? Just an idea.

What are those best practices? Follow no wake signs and do not enter prohibited wildlife sanctuaries, do not feed or touch manatees from a boat, and use snorkel gear (it is not as loud and intrusive to the manatees). Call 1-888-404-FWCC if you were to see an injured, dead, tagged or orphaned manatee.
