The seascape of North-West Madagascar is one of the most biodiverse regions in the world, and one of the most preserved. Yet various threats are weighting on its fragile ecosystem: petroleum extraction, rare earth exploitation, development of fishing techniques with high environmental impact, mass tourism…

Without change, in a few years, the region will known a profound imbalance, directly threatening its environment and its natural resources. At its center, the island of Nosy Be totally depends on the sea and its generous underwater life to sustain itself. But for how much longer?

A new project aims to educate the people of Nosy Be, particularly the young, about what is at stake in their underwater world. This project has an environmental, social and community reach. In many places in the world, like in Eastern Madagascar, this approach works, it is thus under this angle that we envision to launch this project, with your help, from the beginning of 2019 for a minimum length of 3 years.

Who are we?

5 people, one association, a common project! Tanguy, Arthur and Elina, founders of the association MADA Megafauna, organise since 2013 the Whale Festival. This event, which takes place every year already mobilised more than 800 people: kids, teenagers and adults, from the villages of Madirokely, Ambatoloaka, Dar el Salam, Ambaro, Andilana, Ambodrona. Today the association wishes to grow further by launching a sustainable social and community project based around the protection of marine megafauna.

Stella Diamant, is the founder and leader of the program The Madagascar Whale Shark Project (madagascarwhalesharks.org) in Nosy Be since 2015. This program, assisted by global scientific experts, in collaboration with the association MADA Megafauna, focuses on the population ecology of whale sharks in Madagascar. To this day, more than 300 sharks have been identified by Stella and her team. The project also implemented a code of conduct in 2017 to ensure the longevity of marine tourism in order to protect whale sharks. Thanks to funding from the Clear Reef Social Fund and from the Foundation Vocatio, Stella Diamant initiated a pilot education program in 2018 thanks to support from the Marine Megafauna Foundation.

Bruno, a young local from Nosy Be, is involved in different education projects : the whale festival, the community association Miaraka helping young people’s development, the associative project Tanana’Madio focusing on waste management, and was recently employed by the MWSP to deploy the education program since September 2018. Competent, motivated, involved, sensitive and convinced, it is the animator we want to support to launch our program!

The pilot project

Since the school year 2018, the Madagascar Whale Shark Project launched an education program with a class of 5th, a class of 4th and a class of CM2 for a length of 3 months in partnership with the school La Coline and Les Abeilles of Ambatoloaka and Dar es Salaam. Based on a program first implemented by the Marine Megafauna Foundation (MMF), one of the project partners in Mozambique, it is comprised of lessons, activities, games and movies around the themes of marine megafauna and threats to their survival. This pilot project is delivered by Bruno, assisted by Stella for the theory and by Sophie, school teacher, for the teaching part. The program has three overarching themes (Ecosystems, Giants of the Ocean, Environment) and unrolls over 20 classes of 1h30 each.

Protecting (Dutch) Caribbean Reefs from Unomia stolonifera

Recent reports highlight the concerning spread of the invasive soft coral, Unomia stolonifera, currently devastating Venezuela’s marine ecosystems and detected in Cuba. With the potential threat of its expansion to the (Dutch) Caribbean islands, urgent action and awareness are essential to safeguard marine biodiversity and local economies from possible catastrophic consequences.

Invasive species are animals or plants from another region of the world that don’t belong in their new environment. These species can have major ecological effects by decimating native flora or fauna. They can also cause large economic losses and impact human health. Invasive species also pose a significant threat to marine ecosystems worldwide, including the Dutch Caribbean. Among these invaders is the octocoral species Unomia stolonifera or “Pulsing Xenia”, originally from the Indo-Pacific. With its rapid growth and lack of natural predators, this species can outcompete native species and disrupt fragile marine habitats such as seagrass beds and coral reefs.

Background

The invasive soft coral U. stolonifera was first identified in 2014, off the coast of Venezuela. It is believed to have been introduced via the illegal aquarium trade.  Since this species can reproduce sexually and asexually (or fragment), even small pieces can regenerate to spread.  Once introduced it quickly took over shallow reefs and hard substrate at depths of 0-50 meters, outcompeting local corals and seagrass for space.  Follow on surveys found that this coral species exhibited average percentage cover as high as 80%, vastly outcompeting native corals. In highly colonized areas, fish are disappearing due to loss of habitats.

In 2022, during a survey conducted in Cuba by the University of Havana, an unknown octocoral was discovered which was later identified as the invasive Unomia stolonifera. It is suspected that the coral larvae arrived in ballast water from fossil fuel ships originating from Venezuela, as nearby sites adjacent to Venezuelan ports have been heavily affected by the invasion.

How to help

Prevention through continuous monitoring, particularly in high-risk areas such as marine harbors and oil facilities, is paramount. Early detection plays a pivotal role in mitigating the threat posed by Unomia stolonifera.

The public’s involvement and awareness are also vital. Local communities, recreational divers, tourists, and all stakeholders are urged to participate in early detection efforts by reporting sightings (photo, location and date) of this invasive coral to their respective Protected Area Management Organization (PMO’s)- the Fundacion Parke Nacional Aruba (FPNA)STINAPA BonaireCARMABI Curaçao Saba Conservation Foundation (SCF)Nature Foundation St. Maarten (NFSXM) and St. Eustatius National Parks (STENAPA). If an invaded area is confirmed, follow the recommendations by the local PMO’s.

Keys to Success

Despite the challenges, early detection is key to mitigating the threat posed by Unomia stolonifera. With continued vigilance, research, and community engagement, there is hope for containing this potential issue before it becomes a major threat.

Seagrass Awareness Month brings critical food source for Manatees to centre stage

Published

on

March is Seagrass Awareness Month, and there has never been a more critical time to act to protect seagrass communities across Florida and call to action for everyone to contribute to the health of these vital ecosystems. The state’s manatee population has now suffered four years of elevated mortality rates, largely due to seagrass loss.  While the reduced mortality rate in 2023 may signal some progress, it still underscores the ongoing need for awareness and conservation efforts.

Recent years have seen a critical decline in seagrass, leading to devastating consequences for manatees. In 2021, a record number of manatees died, with many dying of starvation within the Indian River Lagoon (IRL). Nutrient pollution, resulting in widespread algae blooms, caused a catastrophic loss of seagrass, leaving manatees to starve. This alarming situation prompted the declaration of an Atlantic Florida Manatee Unusual Mortality Event in 2021, which is still ongoing and under close monitoring.

In 2023, there were over 550 recorded manatee deaths in Florida, on top of the record number recorded in 2021 of 1,101, followed by 800 recorded manatee deaths in 2022. While the number of manatees starving from a lack of seagrass was lower last winter, the situation remains dire because human-caused nutrient pollution remains much too high. Due to high water levels in Lake Okeechobee, we are already seeing discharges to both coasts, dangerously affecting water quality and possibly the seagrass communities.

Manatees rely on seagrass as a vital food source. There are seven species of seagrass in Florida, all of which are consumed by manatees. However, the IRL, a critical manatee habitat, has lost over 95% of its seagrass biomass due to human-induced harmful algal blooms. On the West Coast, Tampa Bay has lost 12% of its seagrass in 2 years, with some areas at historic lows, and Sarasota Bay has lost approximately 30% of its seagrass since 2016. While habitat restoration projects are underway and there have been some signs that seagrass communities may be rebounding in some areas of the IRL, ultimate success depends upon avoiding future harmful algal blooms by continuing to improve overall water quality.

Patrick Rose, Aquatic Biologist and Executive Director of the Save the Manatee Club, emphasized the importance of Seagrass Awareness Month, stating, “Manatees and seagrass communities have co-evolved over millions of years. Seagrass Awareness Month is an important opportunity to spotlight this critical aquatic resource. Uncontrolled development, lax regulation, and pollution from Florida’s growing human population have fueled the cycle of algae blooms that cause seagrass loss.”

For it’s part, Save the Manatee Club has long worked with partners to rehabilitate and protect Florida’s waterways. Recently, it partnered with the Center for Biological Diversity and Defenders of Wildlife to file a suit against the U.S. Fish and Wildlife Service (FWS) for failing to revise outdated critical habitat for Florida manatees, which has not been updated since its original designation in 1976. As a result, it was announced in June 2022 that FWS has committed to revising critical habitat for the Florida manatee by 2024. In May 2022, the same three groups, together with Earth Justice, sued the Environmental Protection Agency for failing to protect manatees from water pollution in Florida. The case is still pending.

Members of the public are encouraged to take action to protect seagrass and manatees by:

  • Taking the pledge to be Fertilizer-Free™ For Manatees, thus helping to reduce pollution from yard chemicals, which will help prevent harmful algal blooms from forming.
  • Preventing damage to seagrasses by avoiding boating over seagrass beds or trimming up the boat’s motor and idling to a safe depth before getting on plane.
  • Reporting distressed, sick, injured, or dead manatees to the Florida Fish and Wildlife Conservation Commission at 1-888-404-FWCC (3922).
  • Resisting the urge to feed or give water to manatees, which is illegal and can negatively impact their natural behavior.
  • Sign up for our Action Alerts and contact local, state, and federal elected officials to urge them to help manatees and restore the seagrasses throughout Florida.

Seagrass Awareness Month serves as a reminder of the urgent need to protect seagrass communities and the manatees that depend on them. By working together, we can ensure a brighter future for these iconic marine mammals and their vital habitats. Rose concluded, “Everyone must act now—from the individual members of the public to governmental and nonprofit organizations to our elected officials—to disrupt this cycle of pollution and proceed to protect and rebuild the seagrass communities that are essential to the survival of manatees and a host of other species, including fishes, dolphins, sea turtles, and birds that collectively depend on this critical aquatic resource.”

Save the Manatee Club, established in 1981 by the late renowned singer-songwriter, author, and entrepreneur Jimmy Buffett, along with former Florida Governor and U.S. Senator Bob Graham, is dedicated to safeguarding manatees and preserving their aquatic habitat.
