Ecosystem legacy of the introduced N2-fixing tree Robinia pseudoacacia in a coastal forest

Abstract: Habitat invasibility has been found to increase dramatically following the alteration of ecosystem properties by a nonnative species. Robinia pseudoacacia, black locust, is a nitrogen-fixing, clonal tree species that aggressively invades open habitats and expands outside of plantations worldwide. Robinia pseudoacacia stands in Cape Cod National Seashore were particularly susceptible to a hurricane in 1991 that caused widespread blowdown and a dramatic reduction in Robinia in some stands. We used this change to… Show more

“…These observations support previous studies which showed that a significant proportion of invasive alien species, particularly N 2 -fixing species, alter soil characteristics and processes in the areas they invade (Vitousek 1990;Stock et al 1995;Gordon 1998;Maron & Jeffries 2001;Marchante et al 2008;Von Holle et al 2013). These observations support previous studies which showed that a significant proportion of invasive alien species, particularly N 2 -fixing species, alter soil characteristics and processes in the areas they invade (Vitousek 1990;Stock et al 1995;Gordon 1998;Maron & Jeffries 2001;Marchante et al 2008;Von Holle et al 2013).…”

“…This means that some soil conditions, altered by invasion, may persist for a given time even after the removal of the invasive species. For instance, soils invaded by leguminous species, such as Robinia pseudoacacia L. (Von Holle et al 2013) or Lupinus arboreus Sims (Maron and Jefferies 2001), have maintained higher N content than non-invaded areas at least for 14 and 5 years after eradication, respectively. The residual effects on soil by Carpobrotus spp.…”

“…Nevertheless, greenhouse experiments based on seedlings have showed that moderate droughts exacerbate soil N deficiency but increase the biomass of nodules, thus benefitting the black locust over non-fixing tree species [72]. Therefore, it remains an open question to know the effects of recurrent and severe drought on the N-fixing ability of black locust and its persistence, given that this species often improves soil N availability in diverse temperate forest types even several decades after the removal of black locust [73]. The similar N soil concentrations found below oak and living black locust suggest they shared comparable soil nutrient availability.…”
