Oysters are like snakes… you either like them or you hate them. You rarely hear someone say – “yea, their okay”. It’s either I can’t get enough of them, or they are the most disgusting thing in the sea.

That said, they are part of our culture. Growing up here in the Florida panhandle, there were oyster houses everywhere. They are as common on menus as French fries or coleslaw. Some like them raw, some like them in gumbo or stews, others are fried oyster fans. But whether you eat them or not, you are aware of them. They are part of being in the northern Gulf of Mexico.
In recent decades the historic oyster beds that supported so many families over the years have declined in production. There are a variety of stressors triggering this. Increased sedimentation, decreased salinity, overharvesting, not returning old shell to produce new reefs, and many more. The capitol of northwest Florida’s oyster coast is Apalachicola. Many are aware of the decline of harvest there. Certainly, impacted by the “water wars” between our state and Georgia, there are other reasons why this fishery has declined. I had a recent conversation with a local in Apalachicola who mentioned they had one of their worst harvest on record this past year. Things are really bad there.

Despite the loss of oysters and oyster habitat, there has not been a decline in the demand for them at local restaurants. There have been efforts by Florida Sea Grant and others to help restore the historic beds, improve water quality, and assist some with the culture of oysters in the panhandle.
Enter the Bream Fisherman’s Association of Pensacola.
This group has been together for a long time and have worked hard to educate and monitor our local waterways. In 2018 they worked with a local oyster grower and the University of West Florida’s Center for Environmental Diagnostics and Bioremediation to develop an oyster garden project called Project Oyster Pensacola. Volunteers were recruited to purchase needed supplies and grow young oysters in cages hanging from their docks. Participants lived on Perdido, Blackwater, East, and Escambia Bays. Bayous Texar, and Grande. As well as Big Lagoon and Santa Rosa Sound. The small, young oysters (spat) were provided by the Pensacola Bay Oyster Company. The volunteers would measure spat growth over an eight-month period beginning in the spring of 2018. In addition, they collected data on temperature, salinity, and dissolved oxygen at their location.
After the first year, the data suggests where the salinity was higher, the oysters grew better. Actually, low salinity proved to be lethal to many of them. This is a bit concerning when considering the increase rainfall our community has witnessed over the last two years. Despite an interest in doing so, the volunteers were not allowed to keep their oysters for consumption. Permits required that the oysters be placed on permitted living shoreline projects throughout the Pensacola Bay area.

We all know how important oysters are to the commercial seafood industry, but it turns out they are as important to the overall health to the bays ecology. A single oyster has been reported to filter as much as 50 gallons of seawater an hour. This removes sediments and provides improved water clarity for the growth of seagrasses. It has been estimated that seagrasses are vital to at least 80% of the commercially important seafood species. It is well known that seagrasses and salt marshes are full of life. However, studies show that biodiversity and biological production are actually higher in oyster reefs. Again, supporting a booming local recreational fishing industry.
This project proved to be very interesting in it’s first year. BFA will be publishing a final report soon and plan to do a second round. For the oyster lovers in the area, increasing local oysters would be nothing short of wonderful.

Young Longleaf Pine
All of Florida’s ecosystems contain pine trees. There are seven native species in the state; Sand, Slash, Spruce, Shortleaf, Loblolly, Longleaf, and Pond. Each species grows best in its particular environment. Pines are highly important to wildlife habitats as food and shelter. Several species are equally valuable to Florida’s economy. Slash, Loblolly, and Longleaf are cultivated and managed to provide useful products such as paper, industrial chemicals, and lumber. All pines are evergreens, meaning they keep foliage year-round. The leaves emerge from the axil of each scale leaf into long slender needles clustered together in bundles. Needles are produced at the growing tips of each branch and remain on the tree for several years before turning reddish-brown and falling off. The bundles are referred to as “fascicles”. The length and number of needles in each fascicle is one way to help identify the different pine species.
A handy rule of thumb is that pines starting with “S” have needles in twos, while pines starting with “L” have needles in threes. And slash pine, which starts with “SL” has needles in twos and threes. The pond pine is also a three-needled fascicle. Pay attention to their length and the number that are held in a fascicle. Because the numbers per fascicle may vary, be sure to check several fascicles to get an overall sense for the plant! Longleaf has the longest needle, measuring over 10 inches. While sand pine has the shortest needles at around 2 inches in length. Pine cones are also a means for identification. Typically the longer the needle, the bigger the cone. But, they also vary in attachment and “spinyness’.

The outer (dorsal) surface of each seed cone scale has a diamond-shaped bulge, or “umbo,” formed by the first year’s growth. The umbo may or may not be armored with a “prickle,” a sharp point but not quite a spine or thorn, at the tip. As the seed cone continues to grow and expand, the exposed area at the end of each scale grows as well. The larger diamond-shaped area around the umbo, formed in the second year of growth, is called the “apophysis.” The shapes of the prickle, umbo, and apophysis can be helpful in identification. The male and female cones are separate structures, but both are present on the same plant. Pollen is produced by male cones and is carried by the wind to female cones where it fertilizes the ovules. Seeds develop and mature inside the female cones (also called the seed cones) for two years, protected by a series of tightly overlapping woody scales. Some pines open their seed cones after two years to release the seeds, while other pines continue to keep their cones tightly closed past maturity and release seeds in response to the heat of a forest fire.

Soon, two important ecological surveys will begin in Gulf County, concerning both diamondback terrapins and mangroves.
Florida is home to five subspecies of diamondback terrapin, three of which occur exclusively in Florida. Diamondback terrapins live in coastal marshes, tidal creeks, mangroves, and other brackish or estuarine habitats. However, the diamondback terrapin is currently listed as a Species of Greatest Conservation Need (SGCN).
Diamondback terrapin populations, unfortunately, are nationally in decline. Human activities, such as pollution, land development and crabbing without by-catch reduction devices are often reasons for the decline, but decades ago they were almost hunted to extinction for their tasty meat. The recent decline has raised concern of not only federal agencies, but also organizations and community groups on the state and local levels. Diamondback Terrapin range is thought to have once been all of coastal Florida, including the Keys.

Mangroves, a shoreline plant species of south Florida, are migrating north and are now being found in the Panhandle. Both red and black mangroves have been found in St. Joseph Bay. Mangroves establishment could be an important key to a healthy bay ecosystem, as a factor in shoreline restoration and critical aquatic life habitat.
Currently there is a significant data gap for both diamondback terrapin and mangrove populations. Therefore, there is a great need to conduct assessments to learn more about their geographic distribution.

The Forgotten Coast Sea Turtle Center is partnering with UF/IFAS Extension & Florida Sea Grant to assist in surveying and monitoring diamondback terrapins and mangroves in St. Joseph Bay, and we need your help! UF/IFAS Extension & Florida Sea Grant Agent’s Rick O’Connor and Ray Bodrey are providing a training workshop for volunteers and coordinating surveys for St. Joseph Bay. Terrapin surveys require visiting an estuarine location where terrapin nesting sites and mangrove plants are highly probable. Volunteers will visit their assigned locations at least once a week during the months of May and June and complete data sheets for each trip. Each survey takes about two hours, and some locations may require a kayak to reach.
If you are interested in volunteering for these important projects, we will hold a training session on Monday, April 22nd at 1:00 p.m. ET at the Forgotten Coast Sea Turtle Center (located at 1001 10th Street, Port St. Joe).

“The Gulf of Mexico provides food, shelter, protection, security, energy, habitat, recreation, transportation, and navigation – playing an important role in our communities, states, region, and nation. To highlight the value and the vitality of the Gulf of Mexico region, the Gulf of Mexico Alliance conceived an awareness campaign “Embrace the Gulf” for the entire year 2020. The awareness campaign will culminate in a multi-stakeholder, cross-sector celebration of the importance of the Gulf of Mexico throughout the year 2020.” (https://embracethegulf.org/about/)
Join the Gulf of Mexico Alliance as we celebrate the importance of the Gulf of Mexico during the year 2020. The Gulf of Mexico Alliance is a regional partnership that works to “sustain the resources of the Gulf of Mexico. Led by the five Gulf States, the broad partner network includes federal agencies, academic organizations, businesses, and other non-profits in the region. Our goal is to significantly increase regional collaboration to enhance the environmental and economic health of the Gulf of Mexico.” (https://gulfofmexicoalliance.org/about-us/organization/).
The Gulf of Mexico Alliance (GOMA) was established in 2004 by the Governors of the Gulf states, as a response to the President’s Ocean Action Plan. It began as a network of state partnerships that worked together on various strategies related to the GOMA priority issues identified by the Governors of each state. It had strong support from the U.S. Council on Environmental Quality. Today GOMA is led by the EPA and NOAA, with 13 federal agencies support the effort. Learn more.

Tree planting in Mary Esther
The best time to plant a tree is twenty years ago. The second best time is for Arbor Day. Florida recognizes the event on the third Friday in January, but planting any time before spring will establish a tree quickly. Arbor Day is an annual observance that celebrates the role of trees in our lives and promotes tree planting and care. As a formal holiday, it was first observed on April 10, 1872 in the state of Nebraska. Today, every state and many countries join in the recognition of trees impact on people and the environment. Trees are the longest living organisms on the planet and one of the earth’s greatest natural resources. They keep our air supply clean, reduce noise pollution, improve water quality, help prevent erosion, provide food and building materials, create shade, and help make our landscapes look beautiful. A single tree produces approximately 260 pounds of oxygen per year. That means two mature trees can supply enough oxygen annually to support a family of four. The idea for Arbor Day in the U.S. began with Julius Sterling Morton. In 1854 he moved from Detroit to the area that is now the state of Nebraska. J. Sterling Morton was a journalist and nature lover who noticed that there were virtually no trees in Nebraska. He wrote and spoke about environmental stewardship and encouraged everyone to plant trees. Morton emphasized that trees were needed to act as windbreaks, to stabilize the soil, to provide shade, as well as, fuel and building materials for the early pioneers to prosper in the developing state. In 1872, The State Board of Agriculture accepted a resolution by J. Sterling Morton “to set aside one day to plant trees, both forest and fruit.” On April 10, 1872 one million trees were planted in Nebraska in honor of the first Arbor Day. Shortly after the 1872 observance, several other states passed legislation to observe Arbor Day. By 1920, 45 states and territories celebrated Arbor Day. Richard Nixon proclaimed the last Friday in April as National Arbor Day during his presidency in 1970. Today, all 50 states in the U.S. have official Arbor Day, usually at a time of year that has the correct climatological conditions for planting trees. For Florida, the ideal tree planting time is January, so Florida’s Arbor Day is celebrated on the third Friday of the month. Similar events are observed throughout the world. In Israel it is the Tu B Shevat (New Year for Trees). Germany has Tag des Baumes. Japan and Korea celebrate an entire week in April. Even, Iceland one of the most treeless countries in the world observes Student’s Afforestation Day. The trees planted on Arbor Day show a concern for future generations. The simple act of planting a tree represents a belief that the tree will grow and some day provide wood products, wildlife habitat erosion control, shelter from wind and sun, beauty, and inspiration for ourselves and our children.
Trees provide us with benefits including serving as a sound barrier, stormwater abatement, and of course fresh air and oxygen
“It is well that you should celebrate your Arbor Day thoughtfully, for within your lifetime the nation’s need of trees will become serious. We of an older generation can get along with what we have, though with growing hardship; but in your full manhood and womanhood you will want what nature once so bountifully supplied and man so thoughtlessly destroyed; and because of that want you will reproach us, not for what we have used, but for what we have wasted.”
~Theodore Roosevelt, 1907 Arbor Day Message

As the trees begin to turn various shades of red, many people begin to inquire about the Popcorn trees. While their autumn coloration is one of the reasons they were introduced to the Florida environment, it took years for us to realize what a menace Popcorn trees have become. Triadica sebifera, the Chinese tallowtree or Popcorn tree, was introduced to Charleston, South Carolina in the late 1700s for oil production and use in making candles, earning it another common name, the Candleberry tree. Since then, it has spread to every coastal state from North Carolina to Texas, and inland to Arkansas. In Florida it occurs as far south as Tampa. It is most likely to spread to wildlands adjacent to or downstream from areas landscaped with Triadica sebifera, displacing other native plant species in those habitats. Therefore, Chinese tallowtree was listed as a noxious weed by the Florida Department of Agriculture and Consumer Services Noxious Weed List (5b-57.007 FAC) in 1998, which means that possession with the intent to sell, transport, or plant is illegal in the state of Florida. The common name of Florida Aspen is sometimes used to market Popcorn tree in mail-order ads. Remember it’s still the same plant.
Although Florida is not known for the brilliant fall color enjoyed by other northern and western states, we do have a number of trees that provide some fall color for our North Florida landscapes. Red maple, Acer rubrum, provides brilliant red, orange and sometimes yellow leaves. The native Florida maple, Acer floridum, displays a combination of bright yellow and orange color during fall. And there are many Trident and Japanese maples that provide striking fall color. Another excellent native tree is Blackgum, Nyssa sylvatica. This tree is a little slow in its growth rate but can eventually grow to seventy-five feet in height. It provides the earliest show of red to deep purple fall foliage. Others include Persimmon, Diospyros virginiana, Sumac, Rhus spp. and Sweetgum, Liquidambar styraciflua. In cultivated trees that pose no threat to native ecosystems, Crape myrtle, Lagerstroemia spp. offers varying degrees of orange, red and yellow in its leaves before they fall. There are many cultivars – some that grow several feet to others that reach nearly thirty feet in height. Also, Chinese pistache, Pistacia chinensis, can deliver a brilliant orange display.

There are a number of dependable oaks for fall color, too. Shumardi, Southern Red and Turkey are a few to consider. These oaks have dark green deeply lobed leaves during summer turning vivid red to orange in fall. Turkey oak holds onto its leaves all winter as they turn to brown and are pushed off by new spring growth. Our native Yellow poplar, Liriodendron tulipifera, and hickories, Carya spp., provide bright yellow fall foliage. And it’s difficult to find a more crisp yellow than fallen Ginkgo, Ginkgo biloba, leaves. These trees represent just a few choices for fall color. Including one or several of these trees in your landscape, rather than allowing the Popcorn trees to grow, will enhance the season while protecting the ecosystem from invasive plant pests.
