Forest fires in New York City are nearly unprecedented. None have been recorded in Prospect Park in recent history, and while wildfires are part of the natural cycle in some parts of the country, they’re extremely uncommon in urban forests.

Firefighters extinguished a second brush fire in Prospect Park on Saturday, roughly a mile away from the site of Friday night’s larger blaze City Fire Department officials said. Forty smoke eaters responded to a fire near the LeFrak Center at Lakeside ice skating rink at about 2:40 p.

The fire was in an “extremely dense” part of Prospect Park on a hill, and there were no structures nearby to be threatened, an FDNY official said.
