Draco lizards have the amazing ability to be able to fly from tree to tree in search of food, a mate and to avoid predators.

This clip was taken from the third episode of Planet Earth II which focuses on jungles.

Green Iguana Feeding in Florida

7 November 2016

Large wild male Green Iguana Lizard feeding on plants. They are quite stunning multicolored lizards – this one really has more blue than green on its head. Descendants of escaped or released pets – iguanas are now freely breeding in the wild and gradually spreading northward with warm winters. Small iguanas and their eggs have many predators that eat them limiting their numbers, but once they reach two feet tall and larger they have few natural enemies. They can reach six feet in length, but 3 or 4 feet long like this one is more common. This one was spotted in Palm Beach County. Hard winter freezes will generally limit their northward advances to around Palm Beach County and south of Lake Okeechobee.

Saving rock iguanas on Hispaniola

The “Hispaniolan ground iguana“, “Ricord’s ground iguana”, “Ricord’s rock iguana”, or “Ricord’s iguana” is a critically endangered species of rock iguana.

It is found on the island of Hispaniola, and is the only known species of rock iguana to coexist with the rhinoceros iguana. Its natural habitat is dry savanna within three subpopulations in the southwestern Dominican Republic. It is threatened by habitat loss due to agricultural encroachment.

Its generic name is derived from the Ancient Greek “cyclos” meaning “circular” and “ourá” meaning “tail”, after the thick-ringed tail characteristic of all “Cyclura” iguanas. Its specific name is a Latinized form of French Biologist, Alexandre Ricord’s last name; Ricord first wrote of the species in 1826.

Morphological and genetic data indicate that the closest living relative of “C ricordi” is “C. carinata” of the Turks and Caicos Islands.

Ricord’s iguana is a large species of rock iguana with a body length of 49–51 cm in males and 40–43 cm in females with an equally long tail. Ricord’s iguana’s toes are articulated to be efficient in digging and climbing trees.

Their body color is a grayish green flat color marked by five to six bold pale gray chevrons alternating with dark gray to black chevrons. In adults, the dark chevrons are less contrasting than in juveniles. Ricord’s iguana’s eyes have a dark almost black iris and red sclera.

This species, like other species of “Cyclura”, is sexually dimorphic; males are larger than females, and have more prominent dorsal crests as well as larger femoral pores on their thighs, which are used to release pheromones.

Digging deep to save Rock Iguana

By Ali North, 13 Sep 2016

This robust, prehistoric looking species is fighting for survival with all populations covering an area of less than 100 km2.

The soil is hot to touch, the temperature reaches over 37° C in the early morning hours, and someone is covered in dust, lying face down on the ground with their head in a hole in the sand. Not an uncommon sight in certain areas of dry forest on the Caribbean island of Hispaniola.

What could at best be considered unusual behaviour, or even mistaken for illegal activity – egg stealing, a threat facing many reptiles across the globe, is a scientist – Dr Stesha Pasachnik – conducting vital research to help save a large reptile from extinction. The Ricord’s Rock Iguana Cyclura ricordii is a stocky, prehistoric looking creature that occurs in just four sub-populations on Hispaniola (an island shared by the Dominican Republic and Haiti).

Classified as Critically Endangered on the IUCN Red List, the species is fighting for its survival, with a total range of less than 100 km2 and an uncertain global population estimate of fewer than 4,000 individuals. The threats facing this island endemic are broad, and are exacerbated by its restricted range: illegal hunting, predation and disturbance by introduced mammals, agricultural expansion and charcoal production are all ramping up the pressure.

In the early 2000s, a Species Recovery Plan was developed by the IUCN and its implementation brought together five partner organisations. Grupo Jaragua (BirdLife in the Dominican Republic) was one, whose contributions have been instrumental in building a greater understanding of the species and raising environmental awareness among local communities. Ground surveys have revealed the existence of a handful of critical nesting sites, including a population in Haiti that was previously thought to be extinct. These sites, locally called fondos, are small areas with deep dirt/clay soils where the iguanas can dig and lay their eggs in synchrony with the rainy season.

One of the most dense concentrations of iguana nests is Fondo de La Tierra, a conservation area of 26 hectares purchased in 2010 by Grupo Jaragua with funding from the International Iguana Foundation. Since 2006, four fondos have seen a three-fold increase in Ricord’s Rock Iguana nest numbers. Research by Grupo Jaragua, INTEC University in Santo Domingo, Mississippi State University and San Diego Zoo’s Institute for Conservation Research is helping to better understand population size, genetics and the ecology of this and another iguana – the Vulnerable Rhinoceros Iguana Cyclura cornuta. This explains the dust-covered scientists, excavating nests to determine hatching success and retrieve temperature loggers.

Using camera traps and frequent field surveys, Grupo Jaragua has also been able to document and help control one of the many threats facing Ricord’s Rock Iguana: invasive alien species. These include cattle and donkeys (which degrade iguana habitat) and cats, dogs, and mongoose. (which prey upon iguana hatchlings and adults). President of Grupo Jaragua, Yolanda León, adds:

“We are also documenting the severe habitat destruction caused by charcoal production and have been actively involved in advocacy activities to reduce this illegal activity. We are working with journalists, filmmakers, and social media to document and expose the situation”.

Grupo Jaragua has trained 400 teachers about the species’ ecology and the importance of iguana conservation to help foster positive attitudes towards the species, while the use of native and endemic plants in an agroforestry programme, alongside the promotion of bee-keeping as a biodiversity friendly activity, is ensuring that critical habitat for iguanas, birds and other wildlife will remain for generations to come. To ensure the future of Ricord’s Rock Iguana and the habitat it relies on, conservation organisations on the island really are having to dig deep. However, through a huge collaborative effort involving research, land protection and local engagement, there is now genuine optimism that the decline can be reversed.

This is just one of many non-avian species that are the focus of work by the BirdLife Partnership across the globe. A recent survey, supported by the Aage V Jensen Charity Foundation, revealed that 74% of BirdLife Partners are conducting work that benefits or focuses on taxa beyond birds. Over 370 projects were identified worldwide, with Grupo Jaragua’s work on Ricord’s Rock Iguana being just one of over sixty projects involving reptiles.
