Combined effects of an anthropogenic (forest harvesting) and natural (extreme rainfall event) disturbance on headwater streams in New Zealand

Abstract: Although extreme hydrological events are a natural component of river ecosystem disturbance regimes, their frequency is predicted to increase with climate change. Anthropogenic activities have the potential to exacerbate the impact of such disturbances but there are few studies on the combined effects of both anthropogenic and extreme hydrological disturbances on stream ecosystems. We investigated the recovery of stream ecosystems over a 5‐year period following the impact of an anthropogenic (forest clear‐cut … Show more

“…and B. tricaudatus). These responses to severe disturbance are consistent with those seen in the Sierra Nevada [58], Oregon Cascades [59], Appalachians [60], and the Bay of Plenty region in New Zealand [61]. Where the riparian corridor survived the storm (L and H reaches), the macroinvertebrate community responded less dramatically.…”

“…However, with certain exceptions (e.g. Hynes, 1970; Woodward et al ., 2015), studies monitoring the responses of invertebrate communities after floods have shown rapid invertebrate recovery (Herbst et al ., 2019; Baillie et al ., 2020), with an initial decline in abundance usually followed by a rapid increase in both abundance and species richness. Moderate floods may even enhance the mobility of nutrients and sediment, and the complexity of the river habitat (Death, Fuller & Macklin, 2015).…”
