Data from: A test of the umbrella species approach in restored floodplain ponds.

1.The umbrella species approach, where conservation actions targeted for one or a group of species should benefit the broader community, may provide an effective framework to guide habitat restoration. This requires congruence in the response of umbrella and co-occurring species to environmental stress and recovery, and the identification of potential mechanisms by which co-occurring species benefit from conservation of an umbrella species. 2.Past evaluations of this approach have considered only the presence/absence of umbrella species. In addition to presence/absence, we quantified abundance and biomass of both umbrella and co-occurring species to support a more quantitative evaluation of species co-occurrence. Floodplain ponds are restored in British Columbia and the Pacific Northwest to benefit coho salmon Oncorhynchus kisutch, a presumptive umbrella species. To test its effectiveness as an umbrella species, we assessed the relationships between species richness, abundance and biomass of aquatic vertebrates, including vertebrates of conservation concern ("listed"), and benthic invertebrates and the abundance and biomass of juvenile coho. We used ordination to evaluate relationships between species' abundance and biomass and environmental attributes. 3.Positive relationships were identified between coho abundance and biomass and species richness, abundance and biomass of fish and listed species. These relationships were negative for benthic invertebrates. Listed species were located close to coho in ordinations, suggesting they respond to similar environmental features while benthic invertebrates clustered away from coho. 4.Synthesis and applications. We found that where our umbrella species coho is most productive, so are other listed species and fish in general, a relationship that would not have been evident had we evaluated species richness alone. We also reported strong relationships between some environmental features manipulated in the habitat restoration and the presence and productivity of coho and co-occurring species. Our study demonstrates the umbrella species approach has potential to guide habitat restoration when there is congruence in the response of umbrella and co-occurring species to environmental attributes that can be manipulated in the restoration. Where this is possible, one can use restoration designed for one or several umbrella species and successfully restore habitats that are viable for other species, including listed species.1. 伞护种（umbrella species）策略指以单一或类群物种为目标的保护行动可惠及更广的生物群落，该策略可为栖息地修复提供有效的指导框架。这一策略要求伞护种与伴生种（co-occurring species）对环境胁迫与恢复过程的响应具有一致性，同时需明确伴生种从伞护种保护中获益的潜在机制。 2. 过往对该策略的评估仅考量了伞护种的存在与否。本研究除记录伞护种的存在/缺失情况外，还对伞护种与伴生种的丰度与生物量进行了量化，以更定量地评估物种伴生关系。不列颠哥伦比亚省与太平洋西北地区的泛滥平原池塘修复项目旨在惠及银大麻哈鱼（coho salmon，*Oncorhynchus kisutch*）——一种被假定为伞护种的物种。为验证其作为伞护种的有效性，我们评估了水生脊椎动物（包括受保护关注的脊椎动物，即标注为"listed"的物种）的物种丰富度、丰度与生物量，以及底栖无脊椎动物与幼年银大麻哈鱼的丰度和生物量之间的关联。我们采用排序分析（ordination）来探究物种丰度、生物量与环境属性之间的关系。 3. 研究发现，银大麻哈鱼的丰度与生物量，与鱼类及受保护名录物种的物种丰富度、丰度和生物量呈正相关；而与底栖无脊椎动物的上述指标呈负相关。排序分析结果显示，受保护名录物种在空间分布上与银大麻哈鱼较为接近，表明二者对相似的环境特征具有响应；而底栖无脊椎动物的聚类分布则与银大麻哈鱼相去较远。 4. 综合与应用。本研究发现，当作为伞护种的银大麻哈鱼种群生产力最高时，其他受保护名录物种及整体鱼类的生产力也同步达到峰值——这一关联仅通过物种丰富度评估是无法发现的。我们还明确了栖息地修复中调控的部分环境特征，与银大麻哈鱼及伴生种的存在状态和种群生产力之间存在显著关联。本研究证实，当伞护种与伴生种对修复过程中可调控的环境属性具有一致响应时，伞护种策略具备指导栖息地修复的潜力。在此前提下，可通过针对单一或若干伞护种开展修复工作，成功构建可支撑包括受保护名录物种在内的其他物种生存的栖息地。
