In 1950 Lingner left the city government. The Main Department of Green-Space Planning was dissolved as part of an administrative reform, and the borough departments of public gardens were downgraded to offices for the city parks. A City Public Gardens Department was reestablished in 1960, due to the problems that had arisen, and Dr. Helmut Lichey appointed to head it as city public gardens director. Lichey’s efforts also lead to the reestablishment of public gardens departments in the boroughs, which however increasingly had only control and contracting functions. Care and maintenance were in time transferred to the Urban Green Space VEB (state-owned company). After Lichey left office, the city government in 1975 appointed Gottfried Funeck as director of the department. Funeck was dismissed in the middle of 1990 and the management of the City Public Gardens Department was transferred to Dr. Hans Georg Büchner.
