Since the discovery of ash tree ( Fraxinus spp.) killer emerald borer (EAB; Agrilus planipennis) in United States 2002 and Moscow, Russia 2003, substantial detection management efforts have been applied to contain monitor its spread mitigate impacts. Despite these efforts, pest continues within North America. It has European Ukraine is causing sporadic outbreaks native range China. The dynamics EAB's expansion events appear be linked lack resistant trees invaded ranges, facilitated by abundance or planted American susceptible species. We review recently gained knowledge EAB; ecological, economic, social impacts; past with their successes limitations. also highlight advances biological control, mechanisms resistance, new approaches under development, aim guiding more effective management.

Wood-boring pests (WBPs) pose an enormous threat to global forest ecosystems because their early stage infestations show no visible symptoms and can result in rapid widespread at later stages, leading large-scale tree death. Therefore, early-stage WBP detection is crucial for prompt management response. Early of WBPs requires advanced effective methods like remote sensing. This review summarizes the applications various sensing sensors, platforms, monitoring infestations. The current capabilities, gaps future potential accurate are highlighted.

Foresters and natural resource managers are increasingly exploring opportunities for the early detection of emerging forest health concerns. One these concerns is eastern larch beetle (ELB, Dendroctonus simplex LeConte), a native insect tamarack (Larix laricina (Du Roi) K., Koch). Historically, ELB attacked only dead or dying trees, but with climate change, it now becoming damaging disturbance agent that affects healthy trees as well. This shift creates need to evaluate methods used detect quantify impacted areas. In northern Wisconsin, USA, 50 stands aerial polygons were surveyed in field during 2023 growing season explore different tools ELBs. We visited 20 identified by sketch map surveys having mortality, Astrape satellite imagery algorithm disturbed, 10 randomly selected from Wisconsin inventory database (WisFIRs) landscape-level context. For each Random stands, information on species composition, signs ELB, invasive species, water presence was quantified. ELBs common across landscape, not always associated high levels mortality. While overstory tree mortality frequently observed both Astrape, linked Current may be re-evaluated this environment.

Abstract Black ash ( Fraxinus nigra ) wetlands are widespread, forested landscape features in the western Great Lakes region. However, future of these ecosystems is threatened due to impending spread invasive emerald borer (EAB), which results tree mortality, decreased transpiration, and potential shifts wetter, non‐forested conditions. The vulnerability such ecohydrologic likely varies according local hydrologic regimes controlled by settings, but this site‐dependent our ability predict it unknown. Here, we assessed as a function site hydrology 15 undisturbed black from their three most common hydrogeomorphic settings northern Minnesota: lowland, depression, transition. Further, used high‐resolution (1‐cm) surface elevation models assess spatial variability water levels at subset 10 sites. Although observed similar ET groundwater exchange rates among lowland sites were generally drier because elevated position greater level drawdowns (via lower specific yield). We that will exhibit increases following EAB‐induced compared wetter where open evaporation shallow‐rooted understory transpiration offset losses transpiration. Moreover, sites, exhibited minimal microtopographic variation, limiting number microsites for establishment eventual canopy recovery after loss.

Abstract Pest-specific inventories require substantial resources and are often infeasible, creating a need for alternative means of early pest detection. We examined the potential stand to detect forest health threats by using unique dataset mapped eastern spruce dwarf mistletoe (Arceuthobium pusillum Peck.) infestations in black (Picea mariana Mill. B.S.P) stands northern Minnesota, USA. simulated across range sampling intensities; that is, current standard (S) methods adding one plot (S + 1), doubling intensity (2S), halving (S/2), fixed-radius plots transect buffers categorized into low, moderate, high infestation severity. detection at multiple viewing distances along S inventory transects low severity stands. Detection probability increased as increased. Plot-based averaged > 50% moderate except S/2 infestations. Notably, transect-based ≥ 85% 25 100 m. Results suggest could provide opportunities with signatures when observations included. Thus, specialists may consider including pest-specific training foresters methods, requiring modest investment time effort.

Insects, fungi, and diseases play an important role in forest stand development subsequently, management decisions treatments. As these disturbance agents commonly occur within across landscapes, modeling has often been used to inform planning decisions. However, models are rarely benchmarked, leaving questions about their utility.
