    • Native range size and growth form in Cactaceae predict invasiveness and impact 

      Novoa, A.; Kumschick, S.; Richardson, D.M.; Rouget, M.; Wilson, J.R.U. (Pensoft, 2016)
      Many recent studies in invasion science have identified species traits that determine either invasiveness or impact. Such analyses underpin risk assessments and attempts to prioritise management actions. However, the ...
    • Promise and challenges of risk assessment as an approach for preventing the arrival of harmful alien species 

      Keller, R.P.; Kumschick, S. (AOSIS, 2017)
      Background: Harmful alien species impose a growing environmental, economic and human well-being burden around the globe. A promising way to reduce the arrival of new species that may become harmful is to utilise pre-border ...
    • The relevance of using various scoring schemes revealed by an impact assessment of feral mammals 

      Hagen, B.L.; Kumschick, S. (Pensoft, 2018)
      Impact scoring schemes are useful for identifying to what extent alien species cause damage. Quantifying the similarity and differences between impact scoring schemes can help determine how to optimally use these tools for ...
    • Socio-economic impact classification of alien taxa (SEICAT)

    • Soft touch or heavy hand? Legislative approaches for preventing invasions: insights from cacti in South Africa 

      Novoa, A.; Kaplan, H.; Kumschick, S.; Wilson, J.R.U.; Richardson, D.M. (Weeds Science Society of America, 2015)
      The rate of transportation, introduction, dissemination and spread of non-native species is increasing despite growing global awareness of the extent and impact of biological invasions. Effective policies are needed to ...
    • The threats posed by the pet trade in alien terrestrial invertebrates in South Africa 

      Nelufule, T.; Robertson, M.P.; Wilson, J.R.U.; Faulkner, K.T.; Sole, C.; Kumschick, S. (2020)
      The pet trade has been a major pathway for the introduction of vertebrate invaders, but little is known about its role in invertebrate invasions. Here we assess the trade in terrestrial invertebrates (excluding spiders) ...
