To achieve biodiversity gains, landowner engagement in coordinated invasive species control programs across private lands is needed. Understanding landowners' perspectives toward such coordinated control efforts is crucial to facilitating engagement. We conducted in person and mail surveys of 68 landowners in and adjacent to the area of a proposed invasive predator control program in New Zealand. We find that, similar to previous studies, landowners consider the potential socioeconomic and ecological benefits of invasive species control and express a strong desire to enhance native biodiversity. However, we also find that landowners take into account the complexity of the local social and ecological context in which a program will unfold in three ways: they consider (1) the level of contribution by other landowners and urban residents who are benefiting from collective control efforts; (2) the potential for the program to upset the local "ecological balance", leading to increases in other pests; and (3) the probability that the program will be successful given the likelihood of others participating and control tactics being effective. We suggest that managers of coordinated invasive species control efforts may benefit from devoting time and resources toward addressing beliefs about social and ecological context, rather than solely providing financial subsidies and information about control tactics or the impacts of invasive species.
为实现生物多样性的增加，需要土地所有者参与针对私有土地的协调一致的入侵物种控制计划。了解土地所有者对这种协调控制努力的看法对于促进他们的参与至关重要。我们对新西兰一个拟议的入侵捕食者控制计划区域内及周边的68位土地所有者进行了面对面和邮寄调查。我们发现，与之前的研究类似，土地所有者考虑入侵物种控制的潜在社会经济和生态效益，并表达了增强本地生物多样性的强烈愿望。然而，我们还发现，土地所有者会从三个方面考虑计划实施地当地社会和生态背景的复杂性：他们考虑（1）其他从集体控制努力中受益的土地所有者和城市居民的贡献程度；（2）该计划扰乱当地“生态平衡”、导致其他害虫增加的可能性；（3）鉴于其他人参与的可能性和控制策略的有效性，该计划成功的概率。我们建议，协调入侵物种控制工作的管理者可能会受益于投入时间和资源来解决有关社会和生态背景的观念问题，而不是仅仅提供财政补贴以及有关控制策略或入侵物种影响的信息。
