Wildfire dynamics are changing around the world and understanding their effects on ecological communities and landscapes is urgent and important. We report detailed food webs for unburned, low-to-moderate and high severity burned habitats three years post-fire in the Eldorado National Forest, California. The cumulative cross-habitat food web contains 3,084 ontogenetic stages (nodes) or plant parts comprising 849 species (including 107 primary producers, 634 invertebrates, 94 vertebrates). There were 178,655 trophic interactions between these nodes. We provide information on taxonomy, body size, biomass density and trophic interactions under each of the three burn conditions. We detail 19 sampling methods deployed across 27 sites (nine in each burn condition) used to estimate the richness, body size, abundance and biomass density estimates in the node lists. We provide the R code and raw data to estimate summarized node densities and assign trophic links.
野火动态在全球范围内正在发生变化，了解它们对生态群落和景观的影响是紧迫而重要的。我们报告了加利福尼亚州埃尔多拉多国家森林火灾后三年未燃烧、低中度和高强度燃烧生境的详细食物网。累积的跨生境食物网包含 3084 个个体发育阶段（节点）或植物部分，包括 849 种（包括 107 种初级生产者、634 种无脊椎动物、94 种脊椎动物）。这些节点之间有 178655 个营养相互作用。我们提供了在三种燃烧条件下每个条件下的分类学、体型、生物量密度和营养相互作用的信息。我们详细介绍了在 27 个地点（每个燃烧条件下 9 个）部署的 19 种采样方法，用于估计节点列表中的丰富度、体型、丰度和生物量密度估计值。我们提供了 R 代码和原始数据，以估计汇总节点密度并分配营养联系。
