Panhandle Florida Master Naturalist graduates opt to use living shorelines to enhance habitat and protect their coastal properties.

FMNP_Main_IFAS_Vert_Color_thumbThe mission of the Florida Master Naturalist program (FMNP) is to promote awareness, understanding and respect of Florida’s natural environment. FMNP graduates, Paul Bennett and Charlie Lurton have both worked diligently through the permitting process to place living shorelines consisting of oyster shell bags and marsh plants along their coastal properties.

Living Shorelines incorporate a range of natural structures to protect coastal shorelines from erosion and enhance habitat for wildlife. Oyster shell bags, biologs, plants and sand fill may be used or a combination of natural materials may be used in a living shoreline project. These projects provide “soft” shoreline protection that offers economic and ecological benefits to the property owner. They are recommended for use in low wave and erosional settings.

In higher wave energy areas, seawalls and bulkheads may be required for shoreline protection. These types of projects “harden” the shoreline, and do not allow for intertidal habitat and eliminate the natural slope of the shoreline. Hard structure projects can have a detrimental effect on nearby properties as wave energy is deflected from the structure and can increase erosion nearby, alter sand movement and decrease intertidal habitat.

Both Mr. Bennet and Mr. Lurton realized the importance and benefits of shoreline protection using natural materials, both men attributed this knowledge to their experiences in the FMNP. The FMNP graduates worked with the local branch of the Florida Department of Environmental Protection’s (DEP) Florida Coastal Office, Northwest Florida Aquatic Preserves, to obtain funding and permits for the projects. DEP’s Florida Coastal Office has worked with the US Fish and Wildlife Services’ Coastal Program to promote and support living shoreline projects across the Panhandle.

Mr. Lurton worked with seven of his neighbors to create 1,200 linear feet of shoreline. This project on Bayou Grande in Escambia County incorporated 39 oyster reefs, each built of 200 bags of recycled oyster shells. Each bag of recycled oyster shell weighs approximately twenty pounds for a total of 78 tons of shell! 11,300 native grasses and salt tolerant plants will be installed along the shoreline this year.

Mr. Bennet’s project along East Bay in Santa Rosa County consists of 5 reefs built along the mouth of a freshwater marsh located on his property for a total of 10 tons of shell. DEP’s Florida Coastal Office will determine if native grasses and plants are needed for the project in the future.

“The conversation for both of these projects started years before we were able install any materials so it’s rewarding to see them take hold,” said Zachary Schang, environmental specialist with the Northwest Florida Aquatic Preserves. “It was in large part due to the persistence of the property owners who wanted to deal with a natural problem using a natural solution.”

These types of habitat restoration projects allow for ecological and economic benefits for the property owners. The Fl. Master Naturalist Program promotes understanding and awareness of natural resources, these two graduates have demonstrated what it means to be a FMN.

What is the El Niño?

What is the El Niño?

In our last article about the red tides we discussed how the strange weather of 2015 caused some changes in the natural world around Pensacola Beach – mainly, it got warmer. Though climate change is happening, and we just had a major summit on the topic in Paris, the warming of 2015 was most directly impacted by one of the strongest El Niño’s on record.

What is an El Niño?
It is a term most of us have heard and know it has something to do with the climate – that it is associated with warming – but little else about it. It is a climatic phenomena that has been occurring for centuries. It was first reported by Peruvian fishermen around Christmas time – hence the name El Niño (“the child”).

The ocean currents off the coast of Peru, and California, are quite cold – in the 55 F range. These cold currents move from the poles towards the equator along the coast. These cold currents keep the precipitation low and the air dry – “it never rains in Southern California”. Mountains and deserts are associated with these regions as well. The cool air at the top of the mountains flows down and across the landscape towards the ocean – causing the surface waters along shore to move offshore – thus creating a current from the ocean floor to rise to the surface called an upwelling. These upwellings bring with them an abundance of nutrients and, mixed with the high oxygen content of the colder water, provide a soup for plankton growth which is food for an abundance of fish – these are some of the richest fishing grounds in the world.

Every so many years the fishermen noticed the fish would disappear. It usually began around Christmas time and they would have to find another means to make a living until they returned – which they always did. They would note this in their log books and we know now that the El Niño would occupier every 7-11 years. Marine and climate scientists noticed that during these El Niño years other species would suffer and the climate would change – the El Niño was not just about fishing. Measurements showed that the current temperatures off of California and Peru warmed during El Niño years from 50 to 80 degrees! The upwelling would stop, the fish would leave, the seals could not feed their young, it rained in places where it normally does not rain, and drought would occur in other parts of the world. Coral reefs would suffer and other global climate changes would occur.

What they have discovered is that the cold ocean currents from the poles that pass California and Peru typically reach the equator and flow westward towards Indonesia and Australia. As the water moved along the equator it would warm producing the tropical reef world of Southeast Asia and the Great Barrier Reef. But during El Niño years this warm water begins to move eastward – back towards California and Peru. The cause is not fully understood yet. But the dry air of California becomes moist, rain falls, which effects the climate all across the country. One notable event locally is that most of the hurricanes are pushed upwards into the Atlantic and miss the Gulf of Mexico. The El Niño usually last a year. One other note here also. El Niño is typically followed by a year of drastic cooling – the La Niña.

How are the El Niño’s effected by climate change?
Some scientist believe the frequency of El Niño will not change but that the frequency of “super” El Niño’s will – they will increase. “Super” El Niño’s occurred twice in the last 20 years and the impacts on fishing, agriculture, and other human actives have been significant. The over all warming of the oceans will fuel a stronger warming event during an El Niño year. W are currently having the strongest “super” El Niño on record.

We will see what 2016 brings, it will be interesting. I know it is 70 degrees right now (December 28) and there are butterflies in my yard.
