Standish, R.J. 2004. Impact of an invasive clonal herb on epigaeic invertebrates in forest remnants in New Zealand. Biological Conservation 116: 49–58.
Tradescantia fluminensis is widespread throughout northern New Zealand and can become the dominant ground cover of forest remnants that it invades. Epigaeic invertebrates were sampled within three Tradescantia-infested plots and three non-infested plots at each of three sites using pitfall traps. Impacts of Tradescantia were apparent despite large differences in invertebrate assemblages among sites. The impact of Tradescantia could be a result of the weed’s tall, dense vegetation structure and associated microclimate, relative to native ground covers.
