This project will test the hypothesis that insect herbivory is an unrecognized major factor influencing recovery of biological systems following the catastrophic 1980 eruption of Mount St. Helens (MSH). The work will quantify impacts of insect herbivores on two key "ecosystem engineering" plants: lupins, which facilitate soil development; and willows, the main source of three dimensional vegetation structure required by many animals. It will also evaluate the effects of herbivores on bird and mammals assemblages. The proposed work will extend the continuous study of insect herbivore impacts at MSH to 18 years, and of mammal community assembly and response to vegetation to 28 years, providing the most comprehensive data set on vertebrate response to catastrophic disturbance in the coniferous forest biome.How biological systems recover from catastrophic disturbances such as volcanic eruptions is fundamental to a basic understanding of how communities of plants and animals assemble and function, and provides the theoretical basis for environmental restoration. MSH has provided a unique opportunity to test ecological understanding of recovery from disturbance. Our work builds on this legacy by elucidating previously unrecognized mechanisms controlling recovery, and by providing long-term records accessible to future scientists. The project also enhances science education through student involvement and work with the National Volcanic Monument and its non-profit partner, the Mount St. Helens Institute.

该项目将检验以下假设：1980 年圣海伦斯火山 (MSH) 灾难性喷发后，食草昆虫是影响生物系统恢复的一个未被认识到的主要因素。 这项工作将量化昆虫食草动物对两种关键“生态系统工程”植物的影响：羽扇豆，促进土壤发育；柳树是许多动物所需的三维植被结构的主要来源。它还将评估食草动物对鸟类和哺乳动物组合的影响。拟议的工作将把 MSH 对昆虫食草动物影响的持续研究延长至 18 年，对哺乳动物群落组装和对植被的反应的持续研究延长至 28 年，提供关于脊椎动物对针叶林生物群落灾难性干扰的反应的最全面的数据集。生物系统从火山喷发等灾难性干扰中恢复对于基本了解动植物群落如何组装和发挥作用至关重要，并为环境恢复提供理论基础。 MSH 提供了一个独特的机会来测试生态学对干扰恢复的理解。我们的工作建立在这一遗产的基础上，阐明了以前未被认识的控制恢复的机制，并为未来的科学家提供了可访问的长期记录。该项目还通过学生参与以及与国家火山纪念碑及其非营利合作伙伴圣海伦斯山研究所的合作来加强科学教育。
