“…For example, increased ash wood on the ground from emerald ash borer (EAB) infestation causes increases in leaf litter arthropods [67]. Tree-killing invasive insects, like EAB, may also result in changes to leaf litter-dwelling arthropod communities by temporarily increasing the litterfall input, which is then followed by significant light gaps in the canopy [68]. Invasive plants may represent an initial pulse of novel resources for leaf litter arthropods, thereby showing some benefit early on.…”

Leaf litter arthropods are some of the most abundant and diverse communities in forests and provide myriad ecosystem services from decomposition and mineralization to pollination and predation. They are important to forest health and management and, in turn, are affected by how we manage our forests. Various forest management techniques such as clear cutting, burning, and chemical control of invasive species all have differing effects on ground dwelling arthropods and, despite their importance, a review of the literature on these effects does not currently exist. My objective with this paper is to review the effects of different types of forest management on arthropods in leaf litter systems.

“…Ash leaves constituted only a small fraction of litterfall and was substantially reduced relative to the pre-or early-infestation rates (321 kg ha −1 ) reported by Kreutzweiser et al [12]. While ash litter was slightly greater at the new versus old infestation sites, the reduction in either case was not unexpected given the eventual complete death of the ash trees.…”

“…Clustered ash trees are commonly found in riparian areas and their loss can lead to a cascade of effects [9,12,19]. Our study demonstrated that ash mortality at both new and old infestation sites resulted in canopy gaps in areas where ash was clustered, and corresponding changes in litterfall, soil N leaching, and herbaceous plant biomass.…”

“…Recent studies have begun to test this hypothesis. For example, Kreutzweiser et al [12] found that EAB-induced loss of ash trees in streamside riparian forests infested at different times (≈5-year difference between initial infestations), significantly increased canopy openness, reduced litterfall and composition, and increased ash regeneration densities and stand structure. This, in turn, resulted in consistently and often significantly reduced C and macro-nutrient (N, phosphorus (P) potassium (K), and calcium (Ca)) flux to the forest floor.…”

“…Building on the study of Kreutzweiser et al [12], in the present study we examined the impact of canopy gap formation due to ash mortality on C and nutrient fluxes to the forest floor via litterfall, development of understory vegetation biomass, and soil nutrient cycling in streamside riparian areas. The study was conducted in riparian forests that had been infested by EAB in the previous 1-3 years (recent infestation) and in forests infested 8-10 years previously (old infestation).…”

Emerald ash borer (EAB) is an alien invasive species that is spreading across Canada and the United States killing ash trees. In riparian forests where ash may be abundant; loss of ash can induce significant structural changes; including the creation of canopy gaps; changes in light penetration; expansion of ground vegetation; and alteration of soil nitrogen and carbon cycling. In 2014 and 2015, we examined the effects of EAB-caused gaps in riparian forests on soil nutrient dynamics. Two sites with different infestation timelines, a “new” site (mortality in past 2–3 years) and an “old” site (infested 10 years previous) were selected to determine temporal differences in effects of canopy gaps created by ash loss on litterfall, herbaceous ground vegetation, and soil nutrient cycling. Within both sites, plots with clustered dead ash (canopy gap plots—CG) were paired with nearby plots of full canopy and no ash (canopy closed plots—CC), and differences between paired plots determined. Total litterfall was observed at all sites but was only significant at the new infestation site. Reductions in leaf litter deposition in CG plots resulted in reduced N and C flux to the forest floor but soil C and N concentrations, and nitrogen mineralization rates, were not significantly different between CG and CC plots. Nitrate concentration in soil solution was significantly greater in CG plots compared to CC plots at the new infestation sites but showed the opposite trend at the old infestation sites. Herbaceous ground vegetation biomass was significantly greater (up to 10×) in CG plots than in CC plots. Overall, despite changes to riparian forest canopy structure and litterfall, there was no significant difference in soil nutrient cycling between EAB-induced canopy gaps and closed canopy plots after 10 years, suggesting a high resilience of riparian forest soils to EAB infestation

Emerald ash borer (EAB) (Agrilus planipennis Fairmaire), an invasive, phloem‐feeding beetle native to Asia, has killed millions of ash (Fraxinus spp.) trees in North America since it was detected in southeast Michigan in 2002. Consistently high mortality of black ash (Fraxinus nigra) and green ash (F. pennsylvanica) which often occur in riparian forests is a concern given their role in regulating soil moisture and shallow groundwater levels. We monitored and compared hydrologic processes in a riparian forest impacted by EAB invasion and an adjacent unimpacted riparian forest site in southwest Michigan. From 2018 to 2022, we recorded soil moisture, depth to groundwater and meteorological variables at 15‐min intervals throughout the growing season in a canopy gap following EAB‐caused ash mortality and in adjacent, unaffected forest in the Augusta Creek riparian zone. Groundwater contributions to evapotranspiration (ETG) were estimated using a groundwater level fluctuation (WLF) method. Significant differences in volumetric soil moisture content (16%–26% higher in the gap than forest), average depth to water (10 cm in the gap vs. 70 cm below land surface in the forest) and mean daily ETG (0.6 in the gap vs. 3.0 mm per day in the forest) persisted across four growing seasons. Within the gap, prolonged saturation of the near surface may be contributing to a shift from a forested riparian ecosystem to herb and sedge‐dominated wetland. These differences have implications for an array of riparian zone ecosystem services, a concern given the extent of ash mortality already sustained in much of eastern North America.
