New York’s JFK airport is installing barriers to keep turtles away from its runways, according to a June 2013 article in The New York Post.
The barriers, which consist of 4,000 feet of 8 inch wide plastic piping alongside runway 4L, will keep diamondback terrapin turtles living in the area surrounding the airport away from the runway.
The turtles living around the Jamaica Bay region lay their eggs in the sandy area near the runway and taxiways during the annual nesting migration from mid-June to early July. As a result, aircraft often have to use other runways, leading to delays.
Airport staff removed about 1,300 turtles from the runways by hand in June and July 2012.
As many as 20,000 turtles may be living in the marshy area around the JFK airport, according to an expert quoted in the report.
