Non-native pest species: changing patterns mean changing policy issues

摘要

The nature of non-native pest introductions is changing, with implications for policy making. Not only is there concern that the rate of new introductions is rising, but there are also changes in the nature of non-native pest problems to which governments must respond. In particular, integration of agricultural and environmental aspects of non-native species problems is now a priority, and will require new methods to quantify environmental effects and to incorporate complex public attitudes. A goal should be a capacity to assess risk, based on both market and non-market factors, so as to improve decisions about prevention and control.
