摘要:
Programs and policies to minimize the threat of, or mitigate the damages from, invasive species work best if designed in concert with each other. Whether program emphasis should be on prevention or control depends on the biological characteristics and size of the invasive species population, ecological characteristics of invaded ecosystems, the cost and efficacy of prevention measures relative to control measures, and the level of prevention costs borne abroad. Because all of these factors are highly variable, data needs are constant if intervention is to be both effective and economical.
