Jamaica Awareness of Mangroves in Nature

Connecting Students to Nature

Written by

The sun is blazing intensely in a cloudless sky, and the lack of a breeze makes the sulfur, rotten egg-like smell even more intense. It feels like 95°F (35°C) and I am sweating profusely as I trudge through the mangroves, one of my favorite marine ecosystems. It feels like home to me.

After two and a half years of putting the J.A.M.I.N. program on hold, I am quickly reminded how much I missed not only teaching and interacting with students face-to-face, but also being in the mangroves. The same feelings happen to me every time I venture into this amazing ecosystem: feelings of curiosity, awe, and respect, mixed with a sense of calm tranquility. And it is these same kinds of feelings we hope to foster in our students while they participate in our program…

We be J.A.M.I.N. Again!

Written by

I see the twinkle of anticipation in my colleagues’ eyes as they hold up their phones waiting to record me filling my lungs to say, “Gooooood moooorning, Port Antonio High School!” My colleagues at Alligator Head Foundation beam and I grin back at them and wink. We have all waited two and a half years for this moment. This long-awaited welcome officially marks the start of the Jamaica Awareness of Mangroves in Nature (J.A.M.I.N.) and it feels good to be J.A.M.I.N. again.

The last time I was in Jamaica implementing J.A.M.I.N. was in early February 2020, before COVID-19 was declared a global pandemic. When the pandemic hit, none of us imagined that it would be years until we could implement the program again. It crushed me when we had to cancel the remainder of the 2020-21 academic year and then again, the following year. Now, we renew program again with more enthusiasm than ever.

Our partners at the Alligator Head Foundation and the University of the West Indies Discovery Bay Marine Lab are by my side aiding me in implementing the program. I couldn’t be more overjoyed to be working with them again. We fell right back into routine with each other as if no time had passed at all.

A New Mangrove Conservation Program: Mangrove DEALs

Written by

In 2018, we partnered with Alligator Head Foundation to implement our Jamaica Awareness of Mangroves in Nature (J.A.M.I.N.) program in Port Antonio, Jamaica. Through this program, we have educated teachers and youth about the mangrove ecosystem. Although this initiative has …

J.A.M.I.N. Students First to Investigate for Mangrove Disease in Port Antonio

Written by

Giggles, chatter, and the sound of squeaking rubber boots echoed through the mangrove forest surrounding Alligator Head Foundation, where second year J.A.M.I.N. students from Port Antonio and Titchfield High Schools trudged through the thick mangrove mud to reach their square quadrats. Inside the quadrats, they used scientific equipment to collect data for a variety of environmental parameters such as salinity, dissolved oxygen, and mangrove tree height. They also gathered red mangrove leaves that contain necrotic (dead) tissue. The students later conducted an investigation to see if these leaves contained the presence of a disease-causing fungus.

Titchfield High School – A Window into History

Written by

The last time I was at Titchfield High School in Port Antonio, Jamaica, I took a moment to look out the window at the old cannons that line the walls separating the school from the clear turquoise waters of the Atlantic Ocean. I was there with my colleagues from Alligator Head Foundation to implement the J.A.M.I.N. program. It’s hard not to let my imagination run wild, wondering what happened on this spot centuries ago when, long before it became a high school, it was a well-armed British defensive structure called Fort George. And so, the story begins…

Mangrove Tannin: The Power of Healing

Written by

Throughout human history, compounds found in plants and animals have been used to heal an array of medical conditions. Traditional medicine, sometimes referred to as “bush” or “folk” medicine, was used to treat ailments prior to the emergence of modern medicine. Many of these customs are still being practiced today. The healing properties of mangroves were first discovered by those practicing traditional medicine. Like with modern-day medicine, many of its uses were discovered through trial and error. When a cure worked, the knowledge and information was passed along from generation to generation.

Mangrove Tannin: What is it?

Written by

In January, our second-year J.A.M.I.N. students were tasked with collecting a variety of growth measurements from the mangrove trees that they tagged and identified inside their quadrats. Before we started, I wanted to review the characteristics that are unique to each species of mangroves, a skill they learned previously during the first year of the program. I decided to quiz the students instead. “How can we identify the red mangrove?” I asked. The replies came quickly. “Prop and drop roots.” “Pointy, thick leaves.” “Green bean-like propagules.” All correct. But among the flurry of eager replies, one stood out as several students shouted in unison. “Red tannin!”
