During the following year, the city's parks department replanted lawns and flowers, replaced dead trees and bushes, sandblasted walls, repaired roads and bridges, and restored statues.[174][175][176] The park menagerie and Arsenal was transformed into the modern Central Park Zoo, and a rat extermination program was instituted within the zoo.[175] Another dramatic change was Moses' removal of the "Hoover valley" shantytown at the north end of Turtle Pond, which became the 30-acre (12 ha) Great Lawn.[174][176] The western part of the Pond at the park's southeast corner became an ice skating rink called Wollman Rink,[175] roads were improved or widened,[177] and twenty-one playgrounds were added.[176] These projects used funds from the New Deal program, and donations from the public.[176] Moses removed Sheep Meadow's sheep to make way for the Tavern on the Green restaurant.[177][178]
