风景河流项目是保护淡水栖息地的潜在工具，但很少有研究试图描述风景河流内鱼类栖息地的特征。以弗吉尼亚风景河流计划作为案例研究，我们为一组具有代表性的弗吉尼亚淡水鱼类建立了物种分布模型，并测试了模型预测的风景河流栖息地适宜性值是否始终高于整个范围的平均值。我们首先选择了 33 种鱼类，这些鱼类广泛代表了弗吉尼亚州淡水鱼类动物群所组成的完整功能特征空间。该子集包括 11 种国家列为濒危物种。接下来，我们为 33 种鱼类中的每一种建立了最大熵物种分布模型，并使用该模型来预测每个物种范围内的栖息地适宜性。然后总结了国家列出的风景河流内的栖息地适宜性，并与每个物种完整的全州栖息地适宜性分布进行比较。对于 33 个物种中的 21 个物种，模型预测的栖息地适宜性在目前列出的弗吉尼亚风景河流中明显高于全州分布；在这 21 个物种中，有 5 个属于濒危类群。此外，如果所有待决的风景名胜区名录申请获得批准，预计风景名胜河流内的 25 个物种（包括 8 个濒临灭绝的物种）的栖息地适宜性将大大超过整个范围的平均水平。我们的结论是，风景秀丽的河流为弗吉尼亚州的淡水鱼类提供了重要的保护效益。我们还注意到，我们灵活的、基于模型的流程可以应用于其他河流，并用于为其他类型的淡水保护计划提供信息，这些计划旨在识别和保护最高质量的栖息地。
Scenic rivers programs are a potential tool to conserve freshwater habitat but few studies have attempted to characterize fish habitat within scenic rivers. Using the Virginia Scenic Rivers Program as a case study, we built species distribution models for a representative set of Virginia freshwater fishes and tested whether model-predicted habitat suitability values for scenic rivers are consistently higher than the range-wide average values. We began by selecting 33 fish species that were broadly representative of the complete functional trait space comprised by Virginia's freshwater ichthyofauna. This subset included 11 state-listed imperiled species. Next, we built maximum entropy species distribution models for each of the 33 fishes and used the models to predict habitat suitability throughout each species' range. Habitat suitability within state-listed scenic rivers was then summarized and compared with the complete, state-wide distribution of habitat suitability for each species. For 21 of 33 species, model-predicted habitat suitability was significantly higher in currently listed Virginia scenic rivers than in the state-wide distribution; of these 21 species, 5 were imperiled taxa. Furthermore, habitat suitability within scenic rivers is predicted to exceed the range-wide average by a significant margin for 25 species, including eight imperiled species, if all pending scenic listing petitions are approved. We conclude that scenic rivers provide important conservation benefits to Virginia's freshwater fishes. We also note that our flexible, model-based process can be applied in other rivers and used to inform other types of freshwater conservation programs that seek to identify and protect the highest quality habitats.
