“…The introduced emerald ash borer (Agrilis planipennis Fairmaire [EAB]) is one of the more significant non-native insects threatening North American forests given the importance of ash species across numerous forest types and regions [11], and the ability of this insect to cause widespread mortality within 2-6 years of invasion [12]. Most ash species exist as minor components of mixed species forests [11] and loss of canopy ash to EAB will eliminate the unique ecological functions of ash, but forested conditions are expected to persist in these affected ecosystems.…”

Abstract:The arrival and spread of emerald ash borer (EAB) across the western Great Lakes region has shifted considerable focus towards developing silvicultural strategies that minimize the impacts of this invasive insect on the structure and functioning of black ash (Fraxinus nigra) wetlands. Early experience with clearcutting in these forests highlighted the risks of losing ash to EAB from these ecosystems, with stands often retrogressing to marsh-like conditions with limited tree cover. Given these experiences and an urgency for increasing resilience to EAB, research efforts began in north-central Minnesota in 2009 followed by additional studies and trials in Michigan and Wisconsin to evaluate the potential for using regeneration harvests in conjunction with planting of replacement species to sustain forested wetland habitats after EAB infestations. Along with these more formal experiments, a number of field trials and demonstrations have been employed by managers across the region to determine effective ways for reducing the vulnerability of black ash forest types to EAB. This paper reviews the results from these recent experiences with managing black ash for resilience to EAB and describes the insights gained on the ecological functioning of these forests and the unique, foundational role played by black ash.

“…in eastern North America since its accidental introduction from southeast Asia [85]. Ash tree mortality causes widespread, nearly simultaneous formation of canopy gaps in forests [86,87], owing to the low resistance of North American ash species to EAB [88]. The speed, synchrony, and specificity of ash mortality differs from gap-phase dynamics caused by other forest insects.…”

Responses of Ground-Dwelling Invertebrates to Gap Formation and Accumulation of Woody Debris from Invasive Species, Wind, and Salvage Logging

Natural and anthropogenic disturbances alter canopy structure, understory vegetation, amount of woody debris, and the litter and soil layers in forest ecosystems. These environmental changes impact forest communities, including ground-dwelling invertebrates that are key regulators of ecosystem processes. Variation in frequency, intensity, duration, and spatial scale of disturbances affect the magnitude of these environmental changes and how forest communities and ecosystems are impacted over time. We propose conceptual models that describe the dynamic temporal effects of disturbance caused by invasive insects, wind, and salvage logging on canopy gap formation and accumulation of coarse woody debris (CWD), and their impacts on ground-dwelling invertebrate communities. In the context of this framework, predictions are generated and their implications for ground-dwelling invertebrate communities are discussed.

“…The close ecological similarity of F. pennsylvanica implies that in many floodplain forests it has been able to replace U. americana in the canopy, thereby mitigating the impact of DED on these forests. Unfortunately, large numbers of mature Fraxinus trees are now also being lost across northeastern North America due to the invasive emerald ash borer (Agrilus planipennis Fairmaire 1888) (Flower et al 2013, Knight et al 2013. Although this pest will further impact late successional floodplain forests, the prospect of planting disease-tolerant selections of U. americana into large canopy gaps created by dead Fraxinus offers some hope for the ecological recovery of these forests .…”
