I refer to the letters from Kenneth Tong and Claire Fedder headlined 'Ban creates cycle of frustration' (South China Morning Post, February 15), on cycling in country parks. The Agriculture, Fisheries and Conservation Department supports cycling as a healthy recreational activity in country parks. However, in view of the well-established hiking-trail network and difficult terrain, the development of cycling tracks is not easy. We have to pay special attention to the possible environmental impact, the effect on local villagers, possible conflicts with hikers and, more importantly, the safety of all road users, including hikers, cyclists and vehicle drivers. At present, we have designated nine cycling tracks and sites in various country parks. Details of these cycling tracks and sites can be seen at our homepage ( http://www.info.gov.hk/afd/ bicycle/guide.htm). Regarding the use of Sai Kung's Man Dee Road for cycling, we have consulted the Water Supplies (WSD) and Transport departments on its suitability for cycling. The road is a service access of the WSD, and the original purpose in constructing it was solely to provide access for the WSD so it could operate and maintain the High Island Reservoir and the associated waterworks installations. As such, the design standard of the road is not as high as for public roads provided by the Highways Department. Also, in view of the restricted width of the road, with abrupt and hidden bends and no pedestrian way on either side, the departments concerned consider the road unsuitable for the shared use of vehicles, hikers and bicycles. Therefore, the proposal to open the road for cycling cannot be accepted. EDMOND LAM for Director of Agriculture, Fisheries and Conservation
