The Agriculture, Fisheries, and Conservation Department said it had recorded 32 law enforcement cases involving littering or illegal fires in the city's rural areas as of Sunday. Speaking on a radio programme on Monday, the department's assistant director, Esther To, said some of these cases involved tourists, but staff had also seen travellers slowly abiding by the guidelines through continuous promotion efforts. Authorities were also considering whether to require visitors to make prior bookings and pay fees to access popular countryside sites in Hong Kong. A green group earlier called for long-term measures to tackle over-tourism in Sai Kung, saying the number of tents at some campsites had far exceeded the designated capacity during the Lunar New Year holiday. To said a mechanism is needed to boost management at natural attractions. "I would not say the condition is unsatisfactory now, but we see more people going to these places recently. We believe some measures are needed to help strike a balance, and also whether to beef up rubbish collection to manage sites better," she said. To said the department would first collect data on the matter and look into experiences from overseas, before consulting lawmakers in the second half of the year. She added her department had increased staff by around three-fold to help with promotion and education work during holiday periods. Edited by Tony Sabine
