【正文】 anaging visitors,most parks agencies cannot solve funding shortfalls simply by closing their gates and keeping visitors out,for basic conservation management,including control of fire,feral animals and parks don39。t have gates:and if there are no rangers to stop them,people will continue to enter and exploit protected areas,legally or not. In addition,few parks agencies have a legal mandate to close parks to the public pletely,except in very unusual circumstances。though they generally do have the power to impose a wide variety of specific where the legal mandate exists, . to limit numbers or ban particular historical uses,such as horseriding or snowmobiles,it can be difficult for parks agencies to impose such restrictions in practice,unless they first muster strong political support from groups who favour conservation and lowimpact recreation addition, although the legal and financial systems that support parks and their management agencies can survive shortterm political opposition,laws and budgets are themselves human social constructs and need continued political support to survive in the longer term. Parks agencies therefore need to maintain political constituencies who the greater the external pressures they face,the more such support is needed. Such political support may derive from four major groups,namely those who support protected areas for:existence values,conservation and global ecosystem services。local ecosystem services such as drinking water supplies。individual recreational opportunities。and mercial opportunities,such as first two of these groups have little or no negative impact on specific protected ,the former provide rather diffuse and generalized support,rarely linked to marginal electorates or practical second is relevant only for a limited number of protected areas,such as those associated with municipal water catchments.
