Abstract | Invasive plant species are economically costly and ecologically damaging through competition and niche displacement. Lantana (Lantana camara L.) has become one of the most detrimental global invasive weeds affecting agricultural production and contributing to biodiversity decline. Lantana has been reported to reduce native plant species richness and modify soil chemistry yet surprisingly little is known about Lantana soil legacy effects in Australia. To determine the soil legacy effect of Lantana, we collected soil samples from two sites, three populations, directly “under” (i.e., the rhizosphere) and five meters “away” from Lantana in south-east 978-0-646-70156-1 © CAWS & ISQ Queensland. The collected soil was used in a glasshouse experiment to test the effect of Lantana soil legacy on an Australian native tree Blackwood (Acacia melanoxylon). We assessed whether A. melanoxylon biomass, the number and biomass of nodules and specific root length were reduced when plants were grown in soils collected “under” Lantana versus “away” from Lantana in South-east Queensland. We found that A. melanoxylon stem, root and nodule biomass and nodule count were higher when plants were grown in the “away” from Lantana soil as compared to “under” Lantana soil. Our results suggest that there is a Lantana soil legacy effect that reduces native plant growth and symbiotic biota. |
