The Department of Environment will soon find out whether its iguana culling programme is making an impact.

The annual green iguana survey for Grand Cayman will be conducted this month at 158 sites across the island.

According to an article in the DoE’s latest Flicker publication, surveyors will be “collecting records of the number of iguanas detected at each point, their age class and distance from the point center”.

Last year’s survey estimated there were between 1.1 million and 1.6 million green iguanas on Grand Cayman. That figure helped prompt an intense culling programme that began in the last week of October 2018. Since then, more than 800,000 iguanas have been turned in by hunters at the island’s landfill.

The count coincides with the recent hatching season, which also impacts the effectiveness of the cull.

“The cull will have to fight to keep ahead of the surge of hatchling emergence, which could be substantial as it represents the reproductive power of the population that was still alive in May, when numbers of reproductive adults were significantly higher than now,” the article said.

Efforts to keep the green iguana populations down in Cayman Brac and Little Cayman are ongoing. Residents are encouraged to contact the DoE if they spot a green iguana.

Caymanians interested in joining the culling effort can register during working hours at the reception facility at the entrance to the landfill. Cull training opportunities are also available.
