For the restoration of medium and small rivers, the reintroduction of large wood (LW) is crucial. Despite the wide communication of the ecological key functions of LW, residents rejected its reintroduction in a restoration project at the river Mulde (Dessau‐Roßlau, Germany). To determine whether this is a local or widespread phenomenon in Germany, we investigated (a) the German population's attitude toward LW, (b) preferred quantities of LW introduction, and (c) the effects of flood experiences and other sociodemographic characteristics on these preferences. We conducted a nationwide and representative online survey (n = 2,100), including rating‐scale statements and a choice experiment (CE). Regarding the rating statements, we found that a majority of respondents (57–67%) is convinced of the advantages of LW reintroduction. However, 47–60% considered LW to be dangerous for canoeists or during floods. For the CE (n = 743), we defined an LW attribute and added information on possible effects. Conditional logit models showed a strong preference for the highest amount of LW, with an odds ratio 5.47 times higher than for the status quo without LW. We also found that personal flood experiences reduce the preferred LW quantities. In contrast, females, higher educational levels, the youngest and oldest age groups, and especially frequent river visitors preferred higher LW amounts. Since the commitment of young people to environmental issues is currently increasing, we believe that specific environmental education opportunities for this group located along the river can contribute significantly to increase acceptance.

人们为什么喜欢或不喜欢河流中的大木头—德国公众的代表性调查

对于中小河流的恢复，大木材的重新引入至关重要。尽管人们广泛了解LW的生态关键功能，但居民拒绝在Mulde河（德国Dessau-Roßlau）的修复项目中重新引入LW。为了确定这是在德国的一种局部现象还是普遍现象，我们调查了（a）德国人口对轻水的态度，（b）引入轻水的首选数量，以及（c）洪水经验和其他社会人口统计学特征对这些偏好的影响。我们在全国范围内进行了具有代表性的在线调查（n= 2,100），包括等级量表和选择实验（CE）。关于评级声明，我们发现大多数受访者（57-67％）相信重新引入LW的优势。但是，有47-60％的人认为轻量化对皮划艇者或洪水有危险。对于CE（n= 743），我们定义了LW属性并添加了有关可能影响的信息。有条件的logit模型显示出对最高数量的LW的强烈偏爱，其比值比没有LW的情况高5.47倍。我们还发现，个人洪水经历会减少首选的垃圾量。相反，女性，文化程度较高，年龄最小和年龄最大的人群，特别是经常来河的游客更喜欢较高的LW量。由于年轻人对环境问题的承诺目前正在增加，因此我们认为，沿河这一群体的特殊环境教育机会可以极大地促进人们对环境问题的接受。
