Surviving the Unthinkable: The Mountain Chicken Frog’s Odyssey to Existence

In the heart of the Caribbean, where lush rainforests and pristine waters meet, a remarkable story of conservation and collaboration unfolds. The Critically Endangered Mountain Chicken Frog (Leptodactylus fallax) has been teetering on the brink of extinction for years, but a recent emergency population survey, conducted with the support of national, regional, and international partners, brings a glimmer of hope for these charismatic amphibians.

The Challenge
The Mountain Chicken Frog, affectionately known as the “Kwapo” or “Crapaud” in Dominica’s Kwéyòl language in part because of its large size, is native to the islands of Dominica and Montserrat. With its unique features, including an intriguing call that is sometimes mistaken for a faint dog bark, this frog is an icon of biodiversity in the Caribbean. Once abundant throughout these paradisiacal landscapes, it has suffered a catastrophic decline, primarily due to the deadly chytrid fungus and habitat loss, along with an array of other threats that are pushing it to the brink of extinction.

The chytrid fungal disease has spread its spore-laden grip across the Caribbean and the Americas, infiltrating habitats and wreaking havoc on frog populations since the 1990s. For the Mountain Chicken Frog who came face to face with the fungus in 2002, the impact has been nothing short of catastrophic. In just one year following the introduction of the chytrid fungus, their population plummeted by a staggering 80%, making it one of the fastest amphibian declines ever recorded.

Jeanelle Brisbane, Assistant Forest Officer of the Forestry Division in Dominica and Founder of WildDominique, reflected on how the soundscape of the forests on her home island has changed since. “Imagine a bustling forest teeming with life, where the chorus of these frogs once resonated through the night. Now, picture that same forest almost eerily silent, with only a faint whisper of what was once there. This is the shocking reality of the Mountain Chicken Frog’s rapid decline.”

However, hope emerged from the darkness, as a recent study revealed signs of resilience to chytrid in some individuals surviving in the wild in Dominica, the key to the frog’s return across the islands.

The Emergency Population Survey
Recognizing the urgency of the situation, a coalition of partner NGOs, including a local wildlife organization, national governments, regional conservation bodies, and international agencies across 11 countries, embarked on an ambitious journey to survey and understand the current state of the Mountain Chicken Frog population. Their dedication and commitment were extraordinary, as the
challenges included rugged terrain, dense vegetation, and an unusually low level of rain.

The survey, spanning over 950 field hours and covering extensive areas of the last known habitat, allowed for the collection of invaluable data that is being used to assess the frog’s population size, health, and distribution. Yet, despite the long nights searching feverously in the field, the team only managed to find 23 individual frogs, with two found dead on the road – a stark reminder of just how perilous the situation has become.

Kaysie Ryan, coordinator of the Mountain Chicken Recovery Programme based in Montserrat, said, “The work conducted in Dominica was a great effort from all parties involved but a huge eye opener. There is now a new sense of urgency to get this species protected in Dominica as the conditions within the hotspots have worsened. The future of this species depends on immediate conservation action so that the future of the Mountain Chicken and bringing them back to our forests is possible on both Dominica and Montserrat.”

Hope Springs from Crisis
The Critically Endangered Mountain Chicken Frog stands at a crossroads, and its fate remains uncertain. Nevertheless, the emergency population survey has illuminated a path forward. With the collective dedication of national, regional, and international partners, there is a glimmer of hope for this charming Caribbean amphibian.

The survey managed to uncover signs of ongoing breeding with the finding of froglets and juveniles, the first since Hurricane Maria struck Dominica in 2017. The team also found what is believed to be the oldest living wild Mountain Chicken Frog, a large male whose call still echoes across the valley.

His survival in the wild, despite the chytrid fungus, tropical storms, landslides, flooding, invasive species, mining, and human encroachment, is proof of the resilience of this species. However, the battle is far from over, and the Mountain Chicken Frogs need our support more than ever.

Andrés Valenzuela Sánchez, Research Fellow in Wildlife Health at ZSL’s Institute of Zoology stated, “We’re working to understand how to recover mountain chicken frog populations, but our work shows that the chytrid fungus is not the only threat we must tackle to avoid these frogs being wiped out forever, and we need urgent support to save the species.”

This story is not just about a frog; it’s a testament to the power of collaboration and the indomitable spirit of those who believe in the conservation of our planet’s incredible biodiversity. The plight of the Mountain Chicken Frog is a reminder that, with determination and collective effort, we can turn the tide and preserve the natural wonders that make our world so beautiful and diverse.

Grateful for the number of organisations who have banded together to protect this culturally significant species, Jeanelle stated, “As we work together to protect the Critically Endangered Mountain Chicken Frog, we also reaffirm our commitment to safeguarding the ecological treasures that grace the Caribbean and the entire world. This is a cause worth fighting for, and it’s a fight we intend to win.”
