The recovery of the Jamaican iguana is hard work, as introduced predators like the Asian Mongoose are continually captured to relieve predator pressure. “We catch them and kill them. I’m sorry, that’s just the way it is. The way it has to be”, says Booms, whose real name is Kenroy Williams, with a bashful smile. Booms is a handsome young Jamaican who grew up in southern Kingston before moving seven years ago to work on the Jamaican iguana recovery project.

I ask Booms what his friends and family think of his career choice. “Some think I am crazy when they hear that I am touching the iguanas and the crocodiles. But if they were here like me, they would understand, and they would do everything that I am doing”, he says. As he cradles a young American crocodile, a Vulnerable species, found at night in one of the lagoons fringing the Hellshire Hills, he adds, “You’ve got to respect another life, so that the other life can respect yours. It’s all about respect”.

In order for the iguana to survive without the life support system provided by Booms and team, the Jamaican Iguana Species Recovery Plan outlines steps to establish Goat Islands as a predator-free haven for the large lizard. That was the dream – until now.

“I just returned from Jamaica, and it’s bad”, began an email I received last month from Rick Hudson at Fort Worth Zoo. Hudson has devoted more than twenty years to recovering the iguana, and was distraught. The Jamaican government had announced that it was going to sell Goat Islands to a Chinese conglomerate that had been disbarred by the World Bank for fraud, to build a massive trans shipment port. The development would involve bulldozing the islands, dredging the sea around them, and building a coal-burning plant – in addition to razing forest and concreting over wetland on the mainland for an associated logistics hub. With opposition from local groups led by the Jamaica Environmental Trust falling on deaf ears, Jamaicans were crying out for some international intervention.

Tourism brings in half of all foreign revenue and provides one quarter of all jobs in Jamaica; most tourists who visit the country do so to enjoy pristine beaches, clear waters, ample wildlife and a landscape free from the scars of industrial development. The proposed development is akin to the UK government selling off the Lake District for a quick profit, and could hurt tourism if potential tourism outfits are outraged by the destruction of a natural national treasure. And so, in the humble hope that I could do something to shine a spotlight on what was happening in the international press – to alert potential tourists to Jamaica what the government has planned in the hopes that the government may listen – I boarded a plane to Kingston.

Diana McCaulay, co-founder and CEO of the Jamaica Environment Trust, meets me at the airport and we drive an hour south to the Portland Bight Protected Area, a 187,515-hectare area mosaic consisting of the largest dry limestone forests in the Caribbean and the largest intact mangrove forest in the country. This, the largest Protected Area in Jamaica, contains the Hellshire Hills and Portland Ridge Key Biodiversity Areas (KBAs), defined by IUCN as “places of international importance for the conservation of biodiversity through protected areas and other governance mechanisms”. The area was deemed so special that it was under consideration as a UNESCO Biosphere Reserve, until last year when the government backtracked on the proposal.

Diana introduces me to residents of a fishing community in the heart of Portland Bight Protected Area, Paulette and Herman Coley, who invite me to join them on the water the following morning. I return the next day a little before 4:30 am to join them and their six-year old son Jabari, who seems less than thrilled about being hauled out of his bed at 4am and dressed in a bright yellow lifejacket and facemask.

Wildlife photographer Robin Moore is an award-winning photographer, author and conservationist who recently visited the Goat Islands in Jamaica after hearing about plans to convert the area into a shipment port. Over the next few days we will be posting the story of his visit and detailing his campaign to prevent the loss of this vital habitat and the species found within it.

As I find shade in a small field station in the Hellshire Hills of Jamaica, a leather-brown lizard with bluish thighs lumbers towards me through forest sprouting from jagged limestone. Its tail scatters red dust as it moves in rhythm with a large flap of scaly skin that swings like a metronome underneath its thick jaws. It stops two bodies length from my feet, tilts its head to inspect me with blood-red eyes and, deciding that I probably don’t pose a threat, collapses onto its stomach to take a well-deserved rest. As we sit in silence, I feel privileged to be in the presence of such a beautiful and iconic creature.

The Critically Endangered Jamaican iguana, Cyclura collie, was described as the “rarest lizard in the world” after its rediscovery in 1990. It has become a flagship for conservation in the West Indies and the subject of an international recovery program.

The Jamaican iguana, Cyclura collei, is a Critically Endangered species that has achieved iconic status through a story of chance, perseverance, collaboration and resurgence. At the start of the 20th century the lizard – the largest native land animal in Jamaica – was thought to survive only on Goat Islands, two small islets close to the Hellshire Hills just south of Kingston. After this population disappeared in 1948, the iguana was believed to be extinct. And then, in 1990, a hog hunter chanced upon an iguana in the limestone forests of Hellshire Hills, triggering exploration that revealed around 50 of the “rarest lizards in the world”.

The iguana promptly became a flagship for conservation in the West Indies and the focus of an international recovery program, and inspired the formation of the IUCN SSC Iguana Specialist Group. A consortium of twelve zoos, spearheaded by the Fort Worth Zoo in Texas, built a facility at Hope Zoo in Kingston to rear eggs and hatchlings brought from the wild. This process of “headstarting” involves rearing hatchling iguanas in the safety of a cage to release them back into the wild once they are big enough to ward off predators – a technique that has worked. Since 1991, the number of recorded nesting females and annual hatchlings has increased over six-fold, with at least 200 individuals in the wild today. The recovery of the Jamaican iguana is, according to the IUCN, “considered one of the greatest success stories in conservation science”.

São Tomé giant treefrog (Hyperolius thomensis)

São Tomé giant treefrog (Hyperolius thomensis)

Species: São Tomé giant treefrog (Hyperolius thomensis)

Status: Endangered (EN)

Interesting Fact: Like many other Hyperolius species, the São Tomé giant treefrog breeds in standing water, but instead of using ponds, this remarkable amphibian lays its eggs in water-filled holes in trees.

As its name suggests, the beautifully coloured São Tomé giant treefrog is endemic to the island of São Tomé, 255 kilometres off the coast of Gabon, and is the largest member of the genus Hyperolius. This amphibian presents a classic example of ‘island gigantism’, whereby certain colonisers on islands tend to evolve to become larger than their mainland relatives. The upperparts of the São Tomé giant treefrog are a uniform green to blue-green colour, while the underside is much more brightly coloured with a marbled pattern of orange, white and black. Like other similar species, this treefrog has expanded toe pads and long legs which make it an adept climber.

There is little information available on the current threats to the São Tomé giant treefrog, but the loss of its forest habitat is thought to have had a severe impact on this species. Forest clearance began on São Tomé in the late 15th century to make way for the cultivation of sugar cane, and dramatically accelerated in the 1800s as a result of the production of coffee and cocoa. At one stage in the early 20th century, São Tomé was the world’s largest producer of cocoa, with around 42 percent of the island being devoted to its production. Deforestation rates have since slowed considerably, but the São Tomé giant treefrog is now restricted to the remnants of original primary forest on the island at elevations above 800 metres.

There are currently no known specific conservation measures in place for the São Tomé giant treefrog. However, it may receive a certain level of protection as a result of its occurrence in Obo National Park.

A study has highlighted how two rare species of Chelonian are being threatened by hunting in India.

Two endemic species of the Western Ghats in India, the Travancore tortoise and the Cochin forest cane turtle are being threatened with extinction due to poaching from indigenous and non-indigenous people. The Chelonians (turtles and tortoises) are the second most imperilled vertebrate group in the world and the two species highlighted in the study are no exception, with the Travancore tortoise classified as Vulnerable (VU) by the IUCN Red List and the Cochin forest cane turtle classified as Endangered (EN). Cochin cane turtles inhabit evergreen forest habitats, and unlike many other turtles, do not require the presence of water. This turtle species is so rare that no scientists saw the species for 70 years between 1912 and 1982. The Travancore tortoise is an omnivore, and can be found in evergreen, moist deciduous, and bamboo forests. This tortoise species is known to produce chorus calls at night, but the purpose of the call is unknown.

The Cochin forest cane turtle

A study published in The Asian Journal of Conservation Biology in 2013 investigated the illegal hunting and consumption of these rare animals, and found that many individuals are caught by non-local forestry workers, including those who work as part of fire management initiatives. However, there was also evidence that Chelonian experts were harvesting these rare species and some individuals even used trained dogs while hunting. The study indicated that 77 percent of the 104 people that were interviewed had consumed the Travancore tortoise and 22 percent had consumed the Cochin forest cane turtle. Chelonian meat was reportedly on sale in local establishments. Although it was found that the primary reason for harvesting wild individuals was for consumption, there was also some evidence that the two species were taken due to superstitions and for medicinal purposes.

The Travancore tortoise

The authors of the report, said, “Wildlife hunting in India is illegal and punishable via the Wildlife Protection Act (WPA) 1972, which includes most of the susceptible species … However, hunting continues to be widespread in several regions of India even though it is disregarded or refuted”. The interviews indicated that all 104 respondents knew the illegality of consuming the two species, but problems with pressing charges and corruption are thought to mitigate the risks.

The authors of the study suggest that a limit on the number of dogs allowed at each indigenous settlement may help to reduce the risk of Chelonian hunting, and that the forest department must make a concerted effort to properly supervise forest staff and educate them about the plight of Chelonians. The authors also highlighted the past success of poster campaigns introduced by the Kerala State Forest Department, which aimed to challenge similar local use of animals. Threatened Chelonians, including the Indian star tortoise, were targeted by the previous campaign, and the authors suggest that this kind of promotion could be repeated for the Travancore tortoise and the Cochin forest cane turtle.

As we approached the end of the rocky shore the Galapagos penguins were awaiting our arrival in their elegant black tailcoats. It had been four months since our last trip and we were all excited to be back with the birds. Some approached us cautiously, others jumped into the water, but most appeared quite indifferent to our presence.

We were all on board the Queen Mabel for this seven day field trip. The team consisted of staff from both the Charles Darwin Foundation and the Galapagos National Park and, having departed from Puerto Ayora on the island of Santa Cruz the previous evening, we arrived into Caleta Iguana on the southern coast of Isabela on the morning of July 16.

Searching along the rugged lava coastline we came across nests with eggs, chicks and adults. This was a great sign and reflected the fact that the conditions this year had been good for the penguins, the water remaining cool enough to provide an abundance of food. This is not always the case. During El Niño years the water temperatures can rise by several degrees, resulting in the penguins primary food source, sardines, moving away from the area to find cooler waters.

In the afternoon we drove around to the Marielas Islands off the west coast of Isabela which is home to the largest population of Galapagos penguins. At this site we went about catching individuals so that we could record size and weight, attach ID tags, and collect samples for genetic analysis. We tagged a total of 78 penguins during the trip, 37 of which we had recorded in previous trips. Using this mark-recapture technique allows us to make population size estimates and track trends which are backed up by an annual census that is carried out every September.

Flightless cormorants were next on the agenda. We visited three colonies around Punta Espinoza on Fernandina where we carried out similar catch and release sampling to the penguins. Forty-eight cormorants were caught in total, only 9 of which had not been previously recorded. This was a surprisingly low percentage of new individuals and could signify that the population size is decreasing, knowledge of which highlights the importance of carrying out such regular surveys.

Our last job was to collect the data recorded by special meteorological loggers which help us to understand the micro-climates in some areas. Once this was complete, the team returned home but will be back in December to carry out the final survey of the year.

Since last year the Galapagos Conservation Trust has been running a Galapagos Penguin Appeal in order to be able to provide continued financial support to this essential monitoring project. For more information, please visit www.penguinappeal.org.
