Results and analysis script from a discrete choice experiment assessing public preferences for rewilding in the Oder Delta

1. Rewilding is an emerging paradigm in restoration science, and is increasingly gaining popularity as a cost-effective ecosystem restoration option. A rewilding framework was recently proposed that contains three integral components: restoring trophic complexity, allowing for stochastic disturbances, and enhancing species’ potential to disperse. However, as of yet, there has been limited quantitative analysis looking at public preference for rewilding and each of its elements.
2. We used a discrete choice experiment approach to determine public preference for rewilding in the Oder Delta. The unique geographical context of the Oder Delta, spreading evenly across two countries, allowed us to analyze differences between the German (n = 1,005) and Polish (n = 1,066) samples.
3. In both countries, we found respondents were willing to pay for rewilding interventions when compared against a status quo option. Notably, preferences were strongest for restoring trophic complexity through promoti..., Choice experiment set-up
To determine respondent WTP for rewilding interventions in the Oder Delta, we conducted a discrete choice experiment. The survey was conducted online in both Germany and Poland, with respondents selected by professional online survey companies to provide a representative sample of the respective national populations. The survey consisted of three sections. The first section contained standard socio-demographic questions and also studied respondents’ prior use of the Oder Delta. The second section contained the choice experiment along with follow up questions assessing respondent comprehension and motivation, and the third section included novel motivational questions assessing respondents’ relationship to the Oder Delta and nature more broadly.
We prepared final choice sets for our study using an efficient Bayesian design optimized for Mixed Logit models, using the software Ngene 1.3. Prior values were obtained from a pilot study conducted on a sample of 250 res..., , # Results and analysis script from a discrete choice experiment assessing public preferences for rewilding in the Oder Delta

1. 野化恢复（rewilding）是修复科学领域的新兴范式，作为一种兼具成本效益的生态修复手段正日益受到青睐。近期有研究提出了一套包含三个核心组成部分的野化恢复框架：恢复营养级复杂性、允许随机干扰发生，以及提升物种的扩散潜力。但截至目前，针对公众对野化恢复及其各组成要素的偏好所开展的定量分析仍较为有限。
2. 本研究采用离散选择实验（discrete choice experiment）方法，探究奥得河三角洲地区公众对野化恢复的偏好。奥得河三角洲独特的跨两国分布的地理背景，使我们得以对比分析德国（有效样本量n = 1,005）与波兰（有效样本量n = 1,066）的受访者群体差异。
3. 研究发现，相较于现状（status quo）方案，两国受访者均愿意为野化恢复干预措施支付费用。值得注意的是，受访者对通过促进……（原文此处截断）以恢复营养级复杂性的偏好最为强烈。
## 离散选择实验设置
为测算受访者对奥得河三角洲野化恢复干预措施的支付意愿（willingness to pay, WTP），我们开展了离散选择实验。本次调研通过专业在线调研公司在德国与波兰同步开展，受访者样本均经过筛选以确保能够代表两国的国民人口结构。调研问卷共分为三个部分：第一部分为标准社会人口统计学问题，同时调研了受访者此前对奥得河三角洲的使用情况；第二部分包含离散选择实验内容，以及用于评估受访者理解程度与参与动机的追踪问题；第三部分则设置了创新性的动机类问题，用于探究受访者与奥得河三角洲及自然环境的关联程度。
本研究采用针对混合logit模型（Mixed Logit models）优化的高效贝叶斯设计，借助Ngene 1.3软件生成最终的选择集。研究所需的先验参数来自一项针对250名受访者开展的预实验……
