公众对生物多样性惊人的高损失率的关注并没有与公众愿意承担无限的成本来阻止灭绝的潮流相匹配。由于保护资源是有限的，因此确定保护优先事项以有效利用这些资源至关重要。为了解决人们对生物多样性丧失的最紧迫关切，管理人员和决策者必须了解这些关切。这项研究调查了与生物多样性和野生动物相关的一系列利益的偏好，以及每一种利益对人们的相对重要性。对美国人口进行了一项调查，以探索公众对通常与生物多样性相关的利益类型的偏好：功利主义（商品和娱乐），生态（确定和不确定），美学，象征性和人文主义。受访者被要求对三个物种的选择集合中的假设物种进行排名，每个物种都简单地描述了一种类型的好处。估计秩序多项logit模型，以建立获益排序，并评价排序对社会人口统计学变量的敏感性。样本预测的平均值表明了每种效益的相对重要性。构建置信区间以评价等级之间的区分程度。生态功能是最重要的调查受访者;商品为基础的利益和人的属性是中等重要性;和娱乐，美学，文学和艺术的象征意义似乎是最不重要的。
Public concern about the alarmingly high rate of biodiversity loss has not been matched by public willingness to bear boundless costs to stem the tide of extinction. Because resources for conservation are limited, setting conservation priorities to use those resources effectively is crucial. To do so in a way that addresses people's most pressing concerns about biodiversity loss, managers and policy makers must understand those concerns. This study investigates preferences for an array of benefits associated with biodiversity and wildlife and the relative importance to people of each. A survey was administered to a sample of the US population to explore public preferences for types of benefits often associated with biodiversity: utilitarian (commodity and recreation), ecological (certain and uncertain), aesthetic, symbolic, and humanistic. Respondents were asked to rank hypothetical species presented in choice sets of three species, each described simply in terms of one type of benefit. A rank-ordered multinomial logit model was estimated to establish a ranking of the benefits and evaluate the sensitivity of the ranking to socio-demographic variables. The means of the sample predictions indicated the relative importance of each type of benefit. Confidence intervals were constructed to evaluate the extent to which the ranks could be distinguished from one another. Ecological functions were most important to survey respondents; commodity-based benefits and human attributes were of moderate importance; and recreation, aesthetics, and symbolic references in literature and art appeared to be least important.
