The Ya'nienhonhndeh region is among the last intact forest in Quebec and has never been commercially logged. This region, located on the traditional territory of the Huron-Wendat Nation, thus serves as a critical ecological benchmark for monitoring larger effects of the transition to more intensely managed forests as well changes in disturbance regimes such as outbreaks of defoliating insects like the spruce budworm. The Ya'nienhonhndeh region may also harbor biodiversity and critical habitats that have been shaped by centuries of natural disturbance dynamics. In this collaboration with the Bureau de Nionwentsïo and the Canadian Forest Service, we will compare differences in species assemblages of forest insects in stands the have regenerated following 1) severe spruce budworm damage with extensive mortality, 2) lighter spruce budworm damage where many large diameter, legacy trees remain and 3) stands which have regenerated from clearcutting which surround the Ya'nienhonhndeh. We will focus specifically on two insect groups: generalist parasitoids which attack defoliating insects and saproxylic insects that are linked to ecological legacies such as large diameter deadwood. We will sample these insects using multiple trapping techniques including flight intercept traps, malaise-type traps, sticky cards and emergence traps placed over existing deadwood. All specimens will be identified to species and will be compared using both generalized linear mixed models and multivariate regression trees. We hypothesize that species richness will be greatest in stands with lighter budworm damage related to the combined presence of legacy habitats and an influx of relatively fresh deadwood from standing trees. We anticipate the severely damaged stands will harbor fewer saproxylic insects in part due a lack of fresh deadwood. We expect both stand types in the Ya'nienhonhndeh will have greater abundance and richness of both insect groups than stands regenerating from clearcuts. As exploitation of Canadian forests continues to expand and continued impacts from climate change accumulate, biodiversity comparisons within the Ya'nienhonhndeh will be a critical reference point for conservation and realistic forest management targets.

Ya'nienhonhndeh地区是魁北克的最后一个完整的森林之一，从未商业登记。该地区位于休伦 - 温达特国家的传统领土上，因此是监测过渡到更深入管理森林的更大影响的关键生态基准，以及灾难制度的变化，例如爆发云杉芽虫（如云杉芽虫）的爆发。 Ya'nienhonhndeh地区也可能是港口生物多样性和关键栖息地，这些栖息地已被数百年来的自然灾害动态所塑造。在与局和加拿大森林服务局的合作中，我们将比较林分中森林绝缘的物种组合的差异。1）在1）重新生成了1）严重的云杉芽虫损坏，2）较轻的云杉芽虫损坏，较轻的云杉芽虫损坏了许多大型直径，遗产，遗留下来的遗物，并从周围恢复过来，这是在周围降级的。我们将专门关注两个绝缘群：通才寄生虫，它们会攻击与生态遗产有关的脱叶层状绝缘层和墨西式绝缘材料，例如大直径枯萎病。我们将使用多种陷阱技术（包括飞行拦截陷阱，不适型陷阱，粘性卡片和出现陷阱上的出现陷阱）对这些绝缘进行采样。所有标本将被识别为物种，并将使用广义线性混合模型和多元回归树进行比较。我们假设物种丰富度将是最大的架子，而较轻的芽虫损害与遗产栖息地的共同存在以及站立树的相对新鲜的枯木的影响相关。我们预计，严重损坏的看台将占有较少的墨西哥昆虫，部分原因是缺乏新鲜的枯木。我们预计，Ya'nienhonhndeh中这两种类型的类型都将使这两个绝缘群的丰富性和丰富性比从清晰切割中再生的支架更大。随着对加拿大森林的剥削不断扩大并因气候变化积累而持续影响，Ya'nienhonhndeh内的生物多样性比较将是保护和现实的森林管理目标的关键参考点。
